| ===For Model 100===
| | There are 2 versions of the system disk, one for Model 100 (and 102) only, and one for both Model 100 & 200. |
| Parts:
| |
| *40pin DIP idc connector
| |
| :http://www.king-cart.com/phoenixent/product_name=HWS15322
| |
| *40pin female idc connector, with polarity notch and strain-relief
| |
| :http://www.king-cart.com/phoenixent/product_name=HWS1877
| |
| *40pin ribbon cable, 20 inches
| |
| :http://www.king-cart.com/phoenixent/product_name=HWS16014
| |
|
| |
|
| Assembly:
| | [[File:DVI_system_disk_1.jpg|200px]] |
| *Crimp the cable in the DIP connector such that if you are looking at the dip connector with the #1 pin top-left and pins pointing away from you, the cable exits to the right, red stripe on top.
| | [[File:DVI_system_disk_2.jpg|200px]] |
| *For the DVI end of the cable...
| |
| **This assumes you ordered the actual DIP connector linked above, or have another one that connects it's pins to the conductors in the same pattern. Not all do. See note below.
| |
| **Grab the red wire and the one next to it as a single pair, and peel the pair away from the rest of the cable for about 2 to 3 inches. Repeat for the rest of wires, so the cable ends in 20 loose pairs.
| |
| **Take a sacrificial IDC connector, with strain relief clip, all snapped together but with no cable, so that the connector makes a thin open slot that's the perfect size for a cable to fit in. This will be used as a wire guide to hold all the loose pairs into their original flat ribbon cable shape so that you can crimp them all in a connector.
| |
| **Take the 1st pair of wires with the red wire, twist the pair 1/2 way, and insert it into the empty slot, right against one end of the slot, so that there is a grey wire at the edge of the slot, and the red wire is one position in from the end of the slot. Repeat the twist & insert for all the remaining pairs, until the whole cable is in the slot, but with every pair twisted.
| |
| **Crimp a new female IDC connector on the end of the cable. Make sure the triangle marker for pin-1 is on the red-stripe side of the cable. Wiggle the bundle of cables around a little to settle all those loose pairs into their proper positions before really crimping. It doesn't matter much which way the polarty notch points. There is room for the cable to fold back over the connector under the DVI if it needs to. What matters is that the pin-1 marker is on the same side of the cable as the red wire.

| ====NOTES====
| | Arcadeshopper has copies of both versions of the system disk. |
| *This pinout flatly violates the pinout written in the Service Manual for the DVI! Never the less, this is the way it actually needs to be wired.
| |
|
| |
|
| *Some DIP IDC connectors connect pin 1 to conductor 1, and pin 40 to conductor 2

| :While some others connect pin 1 to conductor 2, and pin 40 to conductor 1. | |
|
| |
|
| :So, you may possibly NOT need to seperate & twist all those wires, depending on which type of DIP connector you happen to have. | | [https://www.arcadeshopper.com/wp/?page_id=11#!/Disk-Video-Interface-system-disk-26-3806-Model-200/p/143281618/category=28313042 26-3806 for Model 200] |
|
| |
|
| :The DIP IDC connector linked above connects pin 1 to conductor 2, and DOES need to have the conductors split into pairs and twisted. | | ==Cable== |

| | |
| Assembly:
| |
| *Crimp the male connector on one end of the cable. Make sure the red wire goes on the Pin-1 marker on the connector, and ideally put the polarity notch at the end of the cable.
| |
| *On the other end of the cable, same as for the DVI-end above for Model 100.
| |
| | |
| (Pics show the twists on the T102 end instead of the DVI end, but it actually doesn't make a difference where you put the twists.)

| ===Quick-n-Dirty neat trick===
| |
| Another much easier way to get the wires crossed the right way, is just join 2 ordinary female idc connectors with a straight through double ended male-male idc pin header. The arrangement of the female connectors must matter, and I assume that the rule is just match up the red stripe from both cables. Thanks Mike Stein for this trick.
