AT&T 6386 Keyboard

[Shadow Demo Account]

Hello all,

I have an AT&T 6386 and the keyboard is bad. I have a spare keyboard,
but it has a 5-pin DIN plug. The AT&T one has a 9-PIN plug (like an
9-Pin Serial). I looked through the manuals I had left, and couldn't
find the PIN layouts anywhere. I'm assuming that the keyboard works the
same as a normal keyboard that most MS-DOS computers use, and that the
only difference is the connector.

So, hopefully someone knows what the pins are so I can make an adaptor.

Hmm, there are 5 pins on the din that's about 100+ combinations? maybe
I'll try them all!

Thanks!

Can not reach you by e-mail so I guess I'll have to post here.

I have a 6312 that I am using a standard IBM AT 101 key keyboard on.
What I did was to make an adapter cable as follows:

1) Make sure you keyboard controller chip has a part number of
"CSL x" where x is 2-9. I have a couple of 6310 motherboards that
are not labeled with "CSL" and the will not accept IBM AT keyboard
inputs.

2) go to your local computer store and buy a keyboard extender cable.
($2.00 - $5.00)

3) Go to Radio Shack and buy a DB-9P connector and cover. ($2 - $4).

4) Cut connector with pins off of the keyboard extender cable and
wire to the DB-9P connector using the following net list.

DB-9P 5 pin DIN Function
Shield Shield
1 2 Keyboard Data
2 1 Keyboard Clock
3 and 4 4 Ground
9 5 +5 volts

connectors as viewed from the front
DB-9P 5 pin DIN

u
1 2 3 4 5 3 1 * = pin
* * * * x * * x = unused or missing pin
x x x *
6 7 8 9 5* *4
*
2
This should work for you.

I also have an AT+T 6386 WGS made for AT+T by Olivette. Do you have a
manual on the memory board for yours ? My memory board has 2 jumpers
on it and I have no idea what they are for. If you could shed any light
on their purpose, I would appreciate it.

Thanks.

Fred
