I designed that card, and one and a half of the three ASICs (at LSI 
logic) that are on it.  I'm surprised it says Plantir; I thought we were 
called Calera Recognition Systems by then.

The card was for OCR; $2000 new.  When the classiccmp archives are back 
online, you can search it and there is a long message or two where I 
describe how we configured these cards, even multiple cards in one 
system, without having any jumpers.  It is child's play on PCI, but ISA 
bus had no mechanism to make it easy.

I spent a lot more time debugging flaky boards than I spent designing 
it.  It wasn't that the design was bad, but we made about 300 
boards/month and there is always some fallout.  At $2000/pop, it was 
worth my time (at $35K/yr) to the company to sit and debug them.
