I have an unusual looking card with a red plastic tab that you could see on top when the card is placed into position that says "AMICA CPU". The card measures around 6-1/2" x 4-1/2" It is also stamped TECAN CPU on the card. It has a 64 pin connector on one end. I'll try and get a picture.

I can't seem to find any info on it, although AMICA seems to still be in business.

The most important chips are an NEC D2716D, a Signetics MM2716Q, a NEC D780C-1 and a NEC 8251 AC.

Anyone know what this might be from? Data acquisition maybe?

Sounds like a Z80-card for PC/104.
Does the connector look like the one in this link http://www.embeddedarm.com/images/boards/medium/ts-adc16.gif on the right-hand side, or like it might mate with it ?

Yup, it looks like it would fit that connector.

I should also mention the ic's are from 1982, 1983 and according to Wikipedia..."The PC/104 form factor was originally devised by Ampro Computers in 1987".

If it's the chip copyright date, unfortunately that doesn't relate to the manufacture date. For instance, I've got a 386sx sbc made in '93 or later, yet the 386sx has a (copyright) date of 1985 on it, and I don't think the packaging the chip is in was even used in '85.
Maybe if you ask around on a PC/104 or embedded board the board will ring a bell with someone ?
