=Introduction=
Building a REX 

This is a version of [http://bitchin100.com/wiki/index.php?title=REXclassic Steven Adolph's REX Classic] with a modified PCB design. 
It is electrically identical to REX Classic, and uses the REX Classic firmware & software. 

The PCB layout and shape are modified to:
* snap into a 3d-printed carrier to fit the Molex78805 socket
* provide connections for power and PORT_EN for programming the CPLD

'''[[REX:Build_(original_version)|Original version of this page, for building the original REX1]]'''

[https://github.com/bkw777/REX_Classic PCB Source] 
[https://github.com/bkw777/Molex78802_Module Carrier Source]

=Parts & Materials=

* PCB: [https://oshpark.com/shared_projects/2aTIo5Fq OSHPark] or [https://www.pcbway.com/project/shareproject/REX_Classic__BKW_re_spin.html PCBWAY]
* BOM: [https://www.digikey.com/short/tj7bzf3h Digi-Key]
* Carrier: [http://shpws.me/SGNn Shapeways] or [https://www.sculpteo.com/en/print/molex78802_pcb_28-13/Bw4x3yG6 Sculpteo]

Note if ordering from PCBWAY: On the order page, you may have to manually change "Min tracks/spaces" to "6/6mil" 
All tracks & spaces are well over 6 mil (everything is 0.2mm which is almost 8 mil), and that setting drops the price from $50 to $5

ENIG adds a lot of cost on PCBWAY and JLCPCB lately. 
Currently the cheapest way to get an ENIG version for gold contacts (other than OSHPark) is [https://www.elecrow.com/ Elecrow]. 
Upload the gerber zip from the [https://github.com/bkw777/REX_Classic/releases/latest releases], and manually select ENIG and Castellated Holes, and just use the cheapest shipping.

*[http://bitchin100.com/wiki/index.php?title=REX REX1 firmware]
:Start there, and follow the links to whatever is the latest "REX Release x.x Rebuild Package" zip file.

=Procedure=
==Prep the Bare PCB==
Lay a piece of medium grit (100-200) sandpaper face up on a hard flat surface like a cutting board.

Sand the edges of the PCB on the sandpaper just enough to clean off the panelization break-away points.

[[File:Castellation flags.jpg|thumb]]
Use magnification to look closely at the castellated edge contacts for copper or gold "flags" hanging on the edge of most contacts. Scrape them off with an xacto knife. 

==Solder the Electronic Components==
[[File:Soldered top.jpg|thumb]]
[[File:Soldered bottom.jpg|thumb]]
Solder these parts onto the matching labeled locations on the pcb.

:U1 = XCR3064XL
:U2 = 29F800
:U3 = LP2980-3.3
:R1 = 10K
:C1 = 1uF
:TP1 & TP2 = right-angle pin (optional)

Don't be too intimidated by the tiny legs on that TSOP-48 chip. 
Just use magnifying glasses, lots of flux, and the [https://youtu.be/erb6-i54tbo DRAG TECHNIQUE]. 
Another example: https://youtu.be/09qb0KY_IF4

The TP1 and TP2 pins are only needed if you think you will ever perform the hardware modification required to use the [http://bitchin100.com/wiki/index.php?title=Main_ROM_Management_Feature main rom management feature]. See [[FlexROM_100]] or [[FlexROM_102]] to facilitate this.
 


==Clean the Finished PCB==
Even "No-Clean" flux should still be removed as much as possible after soldering.

The best is to use an ultrasonic cleaner and saponifying pcb cleaning solution.

If you don't have that, then at least make sure your flux and solder are both "no-clean", and then use 99% isopropyl alcohol and a brush. This will still leave flux trapped under the chips no matter how much you soak it or wash it, but for no-clean flux it's not ideal but ok.

==Program the CPLD==
Now we need to flash the CPLD (Xilinx) with the '''.jed''' file. This configures the blank CPLD into a functional circuit that actually does something.

*Get the '''.jed''' file from [http://www.club100.org/memfiles/index.php?&direction=0&order=&directory=Steve%20Adolph/REX/info here]. [https://raw.githubusercontent.com/bkw777/REX_Classic/refs/heads/master/VHDL/rexbrd/rexbrd.jed mirror]

*Connect the jtag, 5vdc, and PORT_EN jumper.

==Flash the Firmware==
Follow the REX 4.9 update directions to load the firmware onto the REX. 
The original directions for that are here: [http://bitchin100.com/wiki/index.php?title=REX_Release_4.9 4.9 update directions].

Here are explicit/literal example directions to do that using [https://github.com/bkw777/dl2 dl2] on a Mac, Linux, FreeBSD, or other unix pc. 

(For Windows: instead of dl2,
:Download & unzip the various files manually with a browser instead of cutting & pasting the wget & unzip commands.
:use [https://github.com/bkw777/tsend tsend.ps1] for the bootstrap in place of "dl -v -b FILE.100"
:use [http://bitchin100.com/wiki/index.php?title=LaddieCon#LaddieAlpha LaddieAlpha] for the TPDD server in place of "dl -v -u")

Back up any files off of M100. M100 will be wiped.

Cold reset the M100 (ctrl+pause+reset)

Power off the M100

Install the REX in the M100's Option ROM socket

Connect the [[Model_T_Serial_Cable|serial cable]] between M100 and PC

Power on the M100

'''Install dl2 on a PC:''' 
On the PC, in a terminal window.
$ git clone git@github.com:bkw777/dl2.git
$ cd dl2
$ make all && sudo make install

'''Install TEENY onto the M100:''' 
On the PC:
$ dl -vb TEENY.100

Follow the prompts on the PC and on the M100 screen...

On the M100:
:BASIC
RUN "COM:98N1ENN"

On the PC:
:Enter
:wait...

On the M100:
:Enter
NEW
?HIMEM:CALL9643
:Look at the <code>Top: #####</code> number.
:A 32k machine should say 62213.
:Yours may say something else.
: Use that number in the following CLEAR command.
CLEAR 0,62213
MENU

On the PC:
:Enter
:should be back at a shell prompt now



'''Download the REX Classic setup files'''
$ mkdir rex_setup
$ cd rex_setup
$ wget http://bitchin100.com/wiki/images/3/38/R49_M100T102_260_rebuild.zip
$ wget http://bitchin100.com/wiki/images/6/63/M100_OPTION_ROMS.zip
$ unzip R49_M100T102_260_rebuild.zip
$ unzip M100_OPTION_ROMS.zip

'''Use dl2 to start a TPDD server'''
$ dl -vu

'''Copy RF149.CO to the M100, then run it.''' 
On the M100:
:should be at menu
:TEENY.CO
> L RF149.CO
> Q
:should be at menu
:BASIC
CLEAR 0,55000
MENU
:should be at menu
:run RF149.CO
:Answer Y
:Wait...
:should be at menu

'''Reset the M100 to clear out TEENY and RF149.CO'''
:ctrl+pause+reset
:should be at menu, ram wiped

The flash memory on the REX is now formatted and loaded with REXMGR and a TS-DOS option rom image.

'''Install REXMGR from the REX itself'''
:BASIC
CALL 63012

:should be at menu, REXMGR should appear in menu

REX is now ready to use, and empty except for TS-DOS.

'''Now install an option ROM image. Example: Ultimate Rom II'''
:REXMGR
:press TAB once
:screen should say "TS-DOS* ------"
:press right-arrow once, highlight should move to "------"
:press F2
Loading from image filename: UR2100
Hit any key when TPDD ready.
Loading 0:UR2100.BX ####
:now it should say "TS-DOS* UR2100 ------"

UR2 is now loaded into REX, but not currently selected/active, TS-DOS is. 
What this means is, If you were to go back to BASIC and run <code>CALL 63012</code> right now, it would load TS-DOS, as if you had a TS-DOS option rom in the option rom socket. 
To run UR2, you have to select it in REXMGR first.

:right-arrow to highlight UR2100
:press enter
:Y

UR2 is now the active option rom image. Additionally, the equivalent of <code>CALL 63012</code> was already done for you by REXMGR just as a convenience to skip a step.

F8 back to menu.

Leave dl2 running on PC while you load more rom images.

Ctrl+C to exit dl2 when you're done with it.

=Done!=
That was the last step. You're done! Consult the [http://bitchin100.com/wiki/index.php?title=Special%3ASearch&search=rex&fulltext=Search REX docs] to start using it!

== Summary ==
The original PC-8201 ROM was released in 1983 in Japanese, before the PC-8201'''A''', the "international" version was sold in the US.

This file is from the MAME/MESS ROM collection, but appears to be a good dump of the original N82 BASIC ROM. MAME referred to this file as "3256a41-3b1 n 82 basic.rom0", but there is no indication what those numbers mean.

Hackerb9: Add concatenated ROM file plus M14 ROM

"Model T computer" system rom Y2K patches

==General==
All the KC-85 clones have the same routine holding the century digits, though appearing at different addresses in different system roms.

A Y2K patching rule that applies the same to all machines is to just search for a certain string of 6 bytes wherever it happens to appear, and edit.

Using the hex-editor of your choice:
:{|
|-
|style="text-align: right;| Search for this sequence: || <code>23 36 31 23 36 39</code>
|-
|style="text-align: right;| Replace it with this: || <code>23 36 {{highlight|32}} 23 36 {{highlight|30}}</code>
|}

:0x5A56 0x39 -> 0x30

[[file:TRS-80_Model_100.orig.bin]] 
[[file:TRS-80_Model_100.y2k.bin]]

Most Model 100's have a non-standard pinout for the system rom socket. 
If your original system rom has the part number LH535618 (most will), then you can use [[FlexROM_100]] (optionally with [[Building a REX|REX Classic]]) to install the patched ROM.

If you have a late model without LH535618, then you can use a plain 27C256, or [[FlexROM_102]] (optionally with [[Building a REX|REX Classic]]), or [[28C256_to_27C256]].

File:Tandy 200.us.orig.bin

2026-02-15T08:04:13Z

Hackerb9: Hackerb9 uploaded a new version of File:Tandy 200.us.orig.bin

== Summary ==
This is a concatenation of all three system ROMs on the Tandy 200: M15, M13, and M14, in that order. While not usable on actual Tandy 200 hardware, this is a format used by emulators such as Virtual-T.

The first 40K of the file (0000H to 9FFFH) maps directly to the machine's memory address space. NOTA BENE: the last 32K of the file maps to a bank switched ROM which the Tandy 200 addresses as 0000H to 7FFFH.

Model T System ROMs

2026-02-14T18:56:49Z

Hackerb9: Tandy shouldn't be all caps as it was not an acronym, unlike TRS-80 and NEC.

This is the list of "system ROMs", the builtin software on a chip that came with the Model T. The checksums use CRC32/PKZIP and CRC16/XMODEM. When a [[Model_T_Y2K|Y2K-patched]] versions is available, CRC checksum refers to the original ROM. Also see: the list of [[ModelT_roms|ModelT Option ROM]]s and the [[FlexROM_100|FlexROM 100]].

== Summary ==
The M13 chip on the Tandy 200 contains the 8K of the main system ROM which extends from address 8000H (32K) to 9FFF (40K).

File:Tandy 200.us.orig.bin

2026-02-14T18:34:50Z

Hackerb9: This is a concatenation of all three system ROMs on the Tandy 200: M15, M13, and M14, in that order. While not usable on actual Tandy 200 hardware, this is a format used by emulators such as Virtual-T. The first 40K of the file (0000H to 9FFFH) maps directly to the machine's memory address space. NOTA BENE: the last 32K of the file maps to a bank switched ROM which the Tandy 200 addresses as 0000H to 7FFFH.

Hackerb9: Just note that there is no "Y2K" version of LibROM as it is not needed

This is the list of "system ROMs", the builtin software on a chip that came with the Model T. The checksums use CRC32/PKZIP and CRC16/XMODEM. When a [[Model_T_Y2K|Y2K-patched]] versions is available, CRC checksum refers to the original ROM. Also see: the list of [[ModelT_roms|ModelT Option ROM]]s and the [[FlexROM_100|FlexROM 100]].

Hackerb9: Add CRC16 checksums for all ROMs

This is the list of "system ROMs", the builtin software on a chip that came with the Model T. The checksums used CRC32/PKZIP and CRC16/XMODEM. When a [[Model_T_Y2K|Y2K-patched]] versions is available, CRC checksum refers to the original ROM. Also see: the list of [[ModelT_roms|ModelT Option ROM]]s and the [[FlexROM_100|FlexROM 100]].

=Pens=
[[File:EvidENTpens.jpg|100px|frameless|right]]

A German medical supplies company is manufacturing new pens designed for this plotter mechanism.

They're expensive, especially with the shipping, but, they're new, and you can refill them practically forever for pennies per refill.

https://www.evident-shop.de/en/search?sSearch=stifte

=Gears=
The pinion/spindle gears on the X and Y motors are made of Nylon, which has shrunk over time, and essentially all of these gears are split by now, or soon will be.

===Specs===
:13 tooth
:0.25 modulus
:1.5mm bore
:4.5mm length

These are the specs to re-create the gear from scratch. For example the FreeCAD model below was made by just plugging those values into the involute gear plugin in FreeCAD.

===Sources===


The original gears are nylon. You can't get those any more, but you can get two other forms of new gears.

Jeff Birt of the "Hey Birt!" Youtube channel has commissioned some machined brass gears: https://www.soigeneris.com/alps-printer-plotter-mechanism-pinion-gears

You can also get 3d-printed gears: http://shpws.me/Si9K

CAD model source for the 3d-printed gears: https://github.com/bkw777/ALPS_plotter_gears



To install brass gears, I used a small hobby/electronics table-top vise with plastic jaws (Panavise 301) to press the gears onto the motor shafts without deforming the end of the shaft. The rear end of the shaft is very close to the bearing and so you want to be extra careful to avoid even a tiny impreceptible damage to the shape of the shaft. You can remove a thin metal sheet that covers the motors on the back, and that exposes the motors enough to get the corners of the vise jaws on both ends of the motor shaft without having to remove the motors. The jaws on that model of vise are plastic, so they don't harm the motor shaft on the back of the motors. If you use a steel jaw vice, be sure to protect the rear motor shaft from direct metal to metal contact with the vice jaw, to prevent the vise jaw from deforming the motor shaft.

=Paper=

===Specs===
:plain bond
:4.5" wide
:7/16" core
:up to 3" diameter
:160 feet

Original Radio Shack item was 180 feet but that's not a common size. The Original paper may have been a thinner bond too. 160 feet of plain bond does fit in the machine with room to spare. Often the selling sites will list the roll diameter which removes all guessing.

Typical search term: "4.5" bond roll"

http://www.itplanet.com/parts/Star__87999850.htm

https://www.cibowares.com/4-5-x-160-white-bond-1-ply-register-roll-package-of-20/

http://www.sunshinesupport.com/prod/receipt-paper-rolls/1-ply-45-inch-x-165-paper-25-rolls-45165.htm

=Refilling Pens=

The new pens from the German medical supplies company are pretty expensive considering that they are so small and don’t last very long.

The new pens can be refilled fairly easily with insulin syringes available from local drug stores. Example:
:Walgreens item 677232
:10-pack, 29 gauge, 0.3mL
:super thin syringes for insulin

When looking for alternative inks, you need to know that the original ink is water-based. 
You want to use an ink that is water-based, and uses dye not pigment. In other words, not India ink! That has pigments made of particulates like a paint. That clogs up the wick fibers and the ball and wrecks the pen. You need inks that are purely liquid, which means dyes not pigments. 
The simplest way to identify a good ink is to search for water-based drafting/plotter pen ink.

These Koh-I-Noor/Chartpak model numbers are perfect:
:[https://duckduckgo.com/?q=3080-F-BLA 3080-F-BLA] black
:[https://duckduckgo.com/?q=3080-F-BLU 3080-F-BLU] blue
:[https://duckduckgo.com/?q=3080-F-RED 3080-F-RED] red
:[https://duckduckgo.com/?q=3080-F-GRE 3080-F-GRE] green

Fill a syringe to about the 20 mark. (0.2ml)

Around the tip of the pen (the new plastic german ones) there are 3 vent holes.
Insert the syringe into one of those. Angle towards the center a little to minimize how much the vent passage gets mushed open by the needle.

Slowly, giving the ink time to soak into the fiber filler inside, push the plunger from about 20 to about 10. When you see ink in the other vent holes, you’ve actually gone slightly too far, or too fast.

Put the printer in 80 column mode ( jumper 2 = off ) and LLIST a basic program until the writing looks clean. It may splatter a little at first.

Clean up with a calligraphy pen cleaning solution, like:
:http://artid.com/members/calligraphy/blog/post/1529-pen-and-brush-cleaner-recipe
or Koh-I-Noor Rapido-Eze.

It works to restore old dried pens too if you soak the disassembled parts in a jar for a day or so. Most original (30 year old) pens are not recoverable, but some are.

I have no idea how many times a pen can be refilled before the ball point wears out, but even once is worth it, considering how expensive they are and how quickly they run out. I have only refilled each color about twice so far.

For the original steel barrel pens: 
You have to completely disassemble the pens and soak the parts in the cleaning solution for a few hours, or even days. 
If the metal ball point still does not roll or flow, try passing the tip into a flame briefly to free up the ball from being stuck. This is just for METAL tips! I don't know if it works by melting the dried ink or by expanding the metal around the ball, but it works. It only takes a brief exposure, less than a second. Just pass it above a flame back and forth once or twice, don't hold it in place. This breaks the ball free and allows the ball to roll again, and the ink to flow again. 
You have to inject ink with the pen tip off. You can’t go in through a vent hole like you can for the new plastic pens. 
All in all, I’ve generally had less than 50% success rate refilling and reviving old pens. Even after completely disassembling and cleaning all parts and freeing the stuck ball points. But occasionally it does work, and a few pens are better than no pens.

=Pen/Ink Storage=
Store pens and ink in something that is more vapor-proof than oridinary plastic bags or boxes. You want metal or glass, like glass jars with metal lids or foil bags with actual aluminum foil not merely a silvery appearance.

The plastic ink bottles and pen bodies will lose both alcohol and water right through the plastic over time. If they are stored in ordinary plastic bags or containers, even with seals, the vapor pases right through that plastic over time the same way. So you want to store them inside something that will actually trap the vapor inside over long periods, which slows down the loss of volotiles from the ink. Metal in particular also protects the dye from UV.

Example:
https://www.amazon.com/dp/B006L80T2O/

This item comes with dessicant packs. Do '''NOT''' include the dessicant packs! The whole point is to keep the moisture trapped IN the bag.

They're expensive, especially with the shipping, but, they're new, and you can refill them practically forever for pennies per refill.

=Gears=
The pinion/spindle gears on the X and Y motors are made of Nylon, which has shrunk over time, and essentially all of these gears are split by now, or soon will be.

===Specs===
:13 tooth
:0.25 modulus
:1.5mm bore
:4.5mm length

These are the specs to re-create the gear from scratch. For example the FreeCAD model below was made by just plugging those values into the involute gear plugin in FreeCAD.

===Sources===


The original gears are nylon. You can't get those any more, but you can get two other forms of new gears.

Jeff Birt of the "Hey Birt!" Youtube channel has commissioned some machined brass gears: https://www.soigeneris.com/alps-printer-plotter-mechanism-pinion-gears

You can also get 3d-printed gears: http://shpws.me/Si9K

CAD model source for the 3d-printed gears: https://github.com/bkw777/ALPS_plotter_gears



To install brass gears, I used a small hobby/electronics table-top vise with plastic jaws (Panavise 301) to press the gears onto the motor shafts without deforming the end of the shaft. The rear end of the shaft is very close to the bearing and so you want to be extra careful to avoid even a tiny impreceptible damage to the shape of the shaft. You can remove a thin metal sheet that covers the motors on the back, and that exposes the motors enough to get the corners of the vise jaws on both ends of the motor shaft without having to remove the motors. The jaws on that model of vise are plastic, so they don't harm the motor shaft on the back of the motors. If you use a steel jaw vice, be sure to protect the rear motor shaft from direct metal to metal contact with the vice jaw, to prevent the vise jaw from deforming the motor shaft.

=Paper=

===Specs===
:plain bond
:4.5" wide
:7/16" core
:up to 3" diameter
:160 feet

Original Radio Shack item was 180 feet but that's not a common size. The Original paper may have been a thinner bond too. 160 feet of plain bond does fit in the machine with room to spare. Often the selling sites will list the roll diameter which removes all guessing.

Typical search term: "4.5" bond roll"

=Refilling Pens=

The new pens from the German medical supplies company are pretty expensive considering that they are so small and don’t last very long.

The new pens can be refilled fairly easily with insulin syringes available from local drug stores. Example:
:Walgreens item 677232
:10-pack, 29 gauge, 0.3mL
:super thin syringes for insulin

When looking for alternative inks, you need to know that the original ink is water-based. 
You want to use an ink that is water-based, and uses dye not pigment. In other words, not India ink! That has pigments made of particulates like a paint. That clogs up the wick fibers and the ball and wrecks the pen. You need inks that are purely liquid, which means dyes not pigments. 
The simplest way to identify a good ink is to search for water-based drafting/plotter pen ink.

These Koh-I-Noor/Chartpak model numbers are perfect:
:[https://duckduckgo.com/?q=3080-F-BLA 3080-F-BLA] black
:[https://duckduckgo.com/?q=3080-F-BLU 3080-F-BLU] blue
:[https://duckduckgo.com/?q=3080-F-RED 3080-F-RED] red
:[https://duckduckgo.com/?q=3080-F-GRE 3080-F-GRE] green

Fill a syringe to about the 20 mark. (0.2ml)

Around the tip of the pen (the new plastic german ones) there are 3 vent holes.
Insert the syringe into one of those. Angle towards the center a little to minimize how much the vent passage gets mushed open by the needle.

Slowly, giving the ink time to soak into the fiber filler inside, push the plunger from about 20 to about 10. When you see ink in the other vent holes, you’ve actually gone slightly too far, or too fast.

Put the printer in 80 column mode ( jumper 2 = off ) and LLIST a basic program until the writing looks clean. It may splatter a little at first.

Clean up with a calligraphy pen cleaning solution, like:
:http://artid.com/members/calligraphy/blog/post/1529-pen-and-brush-cleaner-recipe
or Koh-I-Noor Rapido-Eze.

It works to restore old dried pens too if you soak the disassembled parts in a jar for a day or so. Most original (30 year old) pens are not recoverable, but some are.

I have no idea how many times a pen can be refilled before the ball point wears out, but even once is worth it, considering how expensive they are and how quickly they run out. I have only refilled each color about twice so far.

For the original steel barrel pens: 
You have to completely disassemble the pens and soak the parts in the cleaning solution for a few hours, or even days. 
If the metal ball point still does not roll or flow, try passing the tip into a flame briefly to free up the ball from being stuck. This is just for METAL tips! I don't know if it works by melting the dried ink or by expanding the metal around the ball, but it works. It only takes a brief exposure, less than a second. Just pass it above a flame back and forth once or twice, don't hold it in place. This breaks the ball free and allows the ball to roll again, and the ink to flow again. 
You have to inject ink with the pen tip off. You can’t go in through a vent hole like you can for the new plastic pens. 
All in all, I’ve generally had less than 50% success rate refilling and reviving old pens. Even after completely disassembling and cleaning all parts and freeing the stuck ball points. But occasionally it does work, and a few pens are better than no pens.

=Pen/Ink Storage=
Store pens and ink in something that is more vapor-proof than oridinary plastic bags or boxes. You want metal or glass, like glass jars with metal lids or foil bags with actual aluminum foil not merely a silvery appearance.

The plastic ink bottles and pen bodies will lose both alcohol and water right through the plastic over time. If they are stored in ordinary plastic bags or containers, even with seals, the vapor pases right through that plastic over time the same way. So you want to store them inside something that will actually trap the vapor inside over long periods, which slows down the loss of volotiles from the ink. Metal in particular also protects the dye from UV.

Example:
https://www.amazon.com/dp/B006L80T2O/

This item comes with dessicant packs. Do '''NOT''' include the dessicant packs! The whole point is to keep the moisture trapped IN the bag.
