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]]'''

=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!

"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>

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.

Model T System ROMs

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]].
