System Disk

There are 2 versions of the system disk, one for Model 100 (and 102) only, and one for both Model 100 & 200.

Steven Adolph has dissected and copied the system disk files.

-* 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.
-* Arrange the cable on the 40 pin female idc connector such that the red stripe goes to the pin one marker, and the cut end of the cable ends on the side of the connector with the polarity notch, and the cable extends away from the connector on the side opposite the polarity notch. Crimp the cable. Then fold the cable back over the top to snap on the strain relief clip. Now the cable is going the same direction as the key notch.

+==System Disk==
+There are 2 versions of the system disk, one for Model 100 (and 102) only, and one for both Model 100 & 200.
-====NOTE====
+[[File:DVI_system_disk_1.jpg|200px]]
-Some DIP IDC connectors connect pin 1 to conductor 1, and pin 40 to conductor 2<br>
+[[File:DVI_system_disk_2.jpg|200px]]
-While some others connect pin 1 to conductor 2, and pin 40 to conductor 1.
-So, you may, or may not, need to swap the positions of every other wire, the same as for Model 102 below, depending on which type of DIP connector you happen to have.

-The DIP IDC connector linked above connects pin 1 to conductor 2, and does NOT need to have the conductors split into pairs and swapped. With connector linked above, you only have to crimp the cable normally.
+The system disk formatting and files are fully described in the service manual.
-===For Model 102 and 200===
+Arcadeshopper has copies of both versions of the system disk.

-Assembly:
+==Cable==
-*Crimp the female connector on one end of the cable. Make sure the red wire goes on the Pin-1 marker on the connector.
+[[Disk/Video Interface: Cable|Cable]]
-*On the other end of the cable, peel apart the conductors into 20 pairs, about 2 to 3 inches long.
-*Take an extra female connector with strain relief clip and snap it all together without any cable. The strain relief clip on this connector forms a slot that is exactly the right size to hold the cable.
-*Take the first wire pair, with one red wire, flip it over and put it into the loose connector strain relief. Repeat for the remaining 19 pairs. In the end you should have all 40 wires in the slot, each pair flipped over on one side of the connector, and the wires all flat and lined up like a single cable on the other side or the connector.
-*Crimp the female connector (not the makeshift cable guide one) on these wires.
-*Pry apart the clips on the makeshift cable guide, or just break it off.

-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 matters. More explicit and definitive info about that will be added later. Thanks Mike Stein for this info.
