I have finally got the workstation card working. I have a platinum //e
here in my office which I just booted off a disused Mac IIcx running
MacOS 6.0.3 (I first tried a IIsi but it needed 6.0.7 and Appleshare 2.0
only works with 2.0.3).

I found someone to give me the pinouts of the cables and made up some
of my own - I used DE-9 sockets instead of MiniDin-8 as they are much
easier to wire. It turns out that the w/s card may well have been designed
with DE-9 sockets originally - when I translated the 8 pins to 9 I found that
the wires went directly from the 10 pin header to the 9 pin socket with no
crossings.

I found a MiniDin-8 PhoneNet box someone had broken the pins on and so were
throwing it out. I cut the male MiniDin plug off it and soldered a DE-9M
in its place.

Sure. I believe that Appleshare 3.x will also support Apple // booting
(but we had a copy of 2.0 lying around unused so I used that).

I added the Old Mac DE-9 & Signal Name columns to John's table.

I will have to check and see if pin 1 on the header is also ground - if
so I can just wire it straight to pin 1 of the DE-9 socket instead of
jumpering it from pin 3.

Signal name pin 7 on the MiniDin-8 is GPI for general purpose input.

I checked and it is. So the pinout is:

Header Signal DE-9 MiniDin-8

1	Gnd	1	n/c
2	HSKo	6	1
3	GPI	2	7
4	HSKi	7	2
5	Gnd	3	4

7	Tx+	4	6
8	Rx-	9	5
9	Tx-	5	3
10	n/c
