I just rescued an AT&T 6386 WSG workstation that is beautifully made (by Olivetti). It has a i386CPU plus a 387FPU.
It boots up fine to a VGA screen, but there is no traditional PC Keyboard connector socket anywhere! How can I hook up a keyboard?

Does anyone have experiance with this type of AT&T machine?

Also, is there anyplace I might find documentation for this AT&T? I've Googled, but not finding much...:(

Thanks for any help!

Is this the same system as the Olivetti M386/25?

This is a total somewhat educated guess - the 6300 used a standard DB9 female plug on the system unit for the keyboard. Obviously, some kind of weird wiring to fit a 9 pin plug. You have a likely transposition in the thread title "6836" which most likely should be "6386" as stated in post 1 body.

I am just guessing that the same DB9 keyboard input port would be used. It would look exactly like a standard CGA port or a serial port. Yes, the serial port is very likely to be a Male DB9, not a female connection, but if you are just hunting around, would be easy to overlook that and think "serial port".

I didn't have any luck with 6386 and google either, other than it appears to be a very popular choice when it was available. Maybe still available? Chuckle, unlikely.

I have a Olivetti M380/C (Pic here (http://www.flickr.com/photos/andysretrocomputers/2933257899/in/set-72157612165560718/))

It does not use a 'normal' PC keyboard. The system end of the cable is a DB9, and the keyboard end is RJ45 type connector.

Keyboard is quite heavy.

Perhaps you should Google for "6386WGS" instead.
That's WGS as in Work Group Station, not WSG as in Won't Search Google. :-D

Assuming you meant to write "6386 WGS", I have one at home and I'll take a look at mine when I get home in 8 hours and reply back.

That would be like the AT&T 630 terminals, then. I suspect that the keyboard itself is close to PC compatible, just with a different connector. (That's a DE9 for those who like to pick nits. The "B" sized shell is most commonly used for 25-pin connectors. The smaller shell is an "E" size.)

Crap, when I was typing "DB", I just knew the nits would jump out. Repeating over and over to myself DE9 DE9 DE9 ....

I have two machines close to yours:

AT&T 6386SX/EL20 WGS: Has a regular minidin keyboard input

AT&T 6286: Has the 9-pin DIN just like the 6300.

I would give you the pinout of the 9-pin keyboard but it won't help you; the 6300 keyboard has its own ROM code to produce a different signal than the standard IBM keyboard. You can not just buy or build an adaptor for the plug. You have to get a keyboard designed to work with the 6300. Keytronics and Northgate had versions made for the 6300 family, but it might be easier to just look for 6300s or 6286s on ebay and grab them for their keyboards.

Or, you can take a chance and try this: http://groups.google.com/group/comp.sys.att/msg/3acd24e73a6e1b00?hl=en&dmode=source&output=gplain

To ALL: Thanks so much. I never expected so much advice for such a scarce computer!

@chuckcmagee...You have a likely transposition in the thread title "6836" which most likely should be "6386"
You're correct, it's an AT&T 6386 WGS. I make typos when it's late at night..^^
.....It would look exactly like a standard CGA port.
I found the extra DE9 port on the rear of the case.

@andyt31....If you have an extra Keyboard like yours, I would pay you for it!

@ahm....Perhaps you should Google for "6386WGS" instead.(see lame excuse above)

@trixter....AT&T 6386SX/EL20 WGS: Has a regular minidin keyboard input.
AT&T 6286: Has the 9-pin DIN just like the 6300.
Strange that your 386sx wouldn't have the same 9 pin connector as mine!?

Here are pics I took tonight to show the machine. It's loaded with cards and the motherboard is underneath the frame bottom!! Really well made. >>

Good news--I finally found the right keyboard online at this place:
www.computertradeexchange.com

I have to highly recommend them since they have lots of hard-to-find computer parts, good prices and have great service!:D

I have two complete systems of this modle and I thing I have the 6286 WGS as well. I have the original keyboards and monitors and some documentation. I would consider selling all of it, but I'm inFlorida and these machines weight a ton! I used to prepair them for use in Kraft Foods Inc. I've never since seen any computer built to such high quality standards. It's unbelieveable how well these are constructed.

I agree-these are top quality machines.

I'd love one of your ATT-6286 models, but unless you have it with you while you happen to be visiting the Chicago area, the shipping would make it too costly.:eek:
