To whomever(s) were looking for one of these, I
scored out out of a junk
bin today. It's an HP C2502-66500, an 8-bit card with an NCR 53C400A on it,
a DB25F port, and a "HP ScanJet Scanner" label on the back panel. Condition
unknown but physically it's in near-mint shape.
From the number, it is for Scanjet IIP, IIC, etc. - the later true SCSI
series.
Oops! There were several similar HP cards with other numbers and no
labels in the bin, if somebody can provide me with the numbers of interest
I can go back and see what I can find.
