How do I find What Chips were on an Old HP Board?

[johnorun]

I received a batch of boards yesterday, that were sold for "scrap" on Ebay.
One of the boards was an HP power card with one 16 pin chip socket, which was empty.
Some chips were included with this lot and one of the chips is an HP ceramic, Gold Gray trace chip with 16 pins. Maybe this chip originally belonged to this card? I have no way of telling, unless there is some kind of Database for old board/card #s. ???
The card has all Gold-plated circuits--really pretty.

The HP board # is: 03551-66515, REV. A, 88809F.
The gold HP chip # is: 1820-0634, 8735.
Thanks for any info.
