I plan on "extending" my keyboard. And i don't know if i just missed it or what. But i would like to know the pin-outs for the keyboard jack. (that ugly 17 pin thing.) I would like to know all the pin-outs, so i can also connect my mouse and whatever else, to the keyboard. So i need al little as possible wires from the keyboard to the computer. Thanks. brian. bd6@vax1.mankato.msus.edu

Hello. I have a very old, many generations photocopied, schematic
to the 520ST (original model). It includes a pinout of J12 which
is the one that you would like. I also have information from the
back of the MEGA STe book which is the most up to date as far as
the mouse and joystick ports that I could find. I hope there are
no errors and that it helps you....

P.S. Pin 5 on JOY0 (middle button) was a surprise for me, I have
not seen that before... It was Not connected on the schematic I
have... I assume they mean JOY1 up.bjoern@drdhh.hanse.de (Bjoern Kriews) (06/16/91)

(01) ground (02) (no pin, protection) (03) J1 R (04) J1 L (05) J1 D (06) MBut R / J1 Fire (07) J1 U (08) M Y2 / J0 R (09) M Y1 / J0 L (10) M X1 / J0 D (11) MBut L / J0 Fire (12) M X2 / J0 U (13) VCC (+5V) (14) TxData -> 6850 (15) RxData <- 6850 (16) Reset (not used but working on Mega-ST KBD) (17) J1 Pin 5 (18) KBDClk 4 Mhz Hope that helps, Bjoern btw: The keyboard circuit diagram says something about pin 37 of 6301 chip being used as a Caps-Lock indicator -> transistor -> led. Anyone ever got this feature to work ? I have achieved nothing, so I think it has to be made in IKBD's OS.
