  Hi folks,
 Can anyone help identify the keyboard in these photos? (apart from the
 obvious, that it's made by Stackpole and has a part number of 86-90-0048 ;)

 I picked it up for fifty cents at a swap meet in the hopes that it might
 be an ASCII keyboard that I could use in an Apple I replica, but given
 that it has a 40-pin DIP socket, it's clearly not (it was very early in
 the morning, what can I say).  It has a five-pin power header on the top
 left, two red LED indicators, the aforementioned 40-pin DIP socket, and
 only one IC, an SN7414N, so it's obviously not doing much logic. Well it is a
nice keyboard ... better built than todays 39 cent keyboards.
You could be missing the keyboard encoder chip ( the 40 pin socket).
But that still leaves where do you get output from.

Sounds like similar to a keyboard I have but the chip is an 8048 not a
keyboard encoder.  The data was output on the 5pin connector in serial
format. The 8048 micro did the key scanning and serial IO.
