IBM F62 (4704 Model 200) - UK variant

[darkcruix]

I have aquired a F62 (4704 Model 200). It is a UK variant of the F62 with slightly different PCB.

Just wanted to share my wiring guide for a F AT Universal Controller.

The UK version of the IBM 4704 Model 200 aka IBM Model F62 with the part no.
6019319 or similar can be wired to a universal controller for the Model F AT.
Here's the wiring guide:

Top row is sensing PCB, second is the description, and last the Controller
Pin. All layed out in two parts counted from left to right when looking at
the sensing PCB at a normal typing position. F is short for the F AT solder
line and N is short for the 3178 solder line:

Code: Select all

01   02   03   04   05   06   07   08   09   10   11   12   13   14   15
GND  GND  Row1 Row2 Row3 Row4 Row5 Row6 Row7 Row8 GND  GND  GND  GND  Col1
F1   F2   F3   F4   F5   F6   F7   F8   F9   F10  F11  F12  N22  N23  F15
---
16   17   18   19   20   21   22   23   24   25   26   27   28   29   30
Col2 Col3 Col4 Col5 Col6 Col7 Col8 GND  GND  GND  GND  GND  Col9 GND  GND
F16  F17  F18  F19  F20  F21  F22  N24  N25  N26  N27  N28  F23  F29  F30

In the end, all 30 pins on the should have cable leading to the controller.
On the controller, you should see:

• First two GND on the F-row be soldered
• All eight Rows on the F-row be soldered
• Two GND on the F-row be soldered
• Two pins left emprty on the F-row (columns)
• Nine pins on the columns on the F-row soldered
• Last two GND Pins soldered on the F-row
• Seven GND pins on the 3178 row to be soldered

Meanwhile I aquired also a Model 300 .... Let's show that first
