This is very sparsely populated board, based on a Zilog Z53C80, Zilog's version of the 5380 SCSI controller chip.

Does anyone have experience with this card?

I believe it works with other 5380 based drivers?

Does anyone have a manual?

I am particularly interested in finding a card with drivers for SCSI Target mode I.e. To make an 8 bit ISA bus clone appear as a SCSI hard drive to another system. I already have this working with a Symbios 16 bit card and appropriate software which was example code from Symbios Logic.

Can anyone suggest generic 5380 SCSI controller drivers?

I've just bought such adaptor from a local supplier and finding a drivers too.

Early NetBSD (and other *BSD systems) had a generic support for NCR 53C80/53C400 as "nca" device
