Hi,

what is a Packard Bell PB-0081-A (PB IRISA) 16bit ISA card?
Card has 68pin Wide-SCSI connector but only very small square main chip and some more logic. Card looks very simple and wide connector iss not common on ISA cards. Two pin cable could be front panel HDD LED?
I can´t google details about card. And i can´t read chip detail from photo. Is it simple SCSI controller or only some specialised riser card? From what P-B computer is it removed?

Is number "9752" a date stamp - end of 1997 year? Very late for ISA cards.

I know there were very simple SCSI controllers like Adaptec AVA-1502AI but with 50pin connector ( http://geb.ebay.in/m/ImportHubViewItem?itemid=121872945634 )

I appreciate any help that you can provide

The cable is is used on SCSI controllers, but I don't know that is a SCSI card. It looks too simple.

There also are SCSI cards that will only work with specific motherboards, because the SCSI BIOS is located on the motherboard instead of the card.

The external port is male, whereas all SCSI cards I've ever seen have been female.

Also, you would NOT put scsi on isa in 1997. (provided 9752 is an accurate date code)

Why not? I did. 😁

Because scsi2 will saturate the bus? If this was scsi, it would be 20+ mb/s and well beyond the ability of isa to handle.

It is a mistake to think you can solve any major problems just with potatoes.

Well, wide SCSI at least, which is what this card supposedly is (I disagree), can do 20MB/sec. 50 pin "narrow" Fast SCSI is up to 10MB/sec. Under normal conditions, I don't know that ISA can handle more than 5MB/sec.

There are some...exotic...solutions that let you slave another computer (usually a special dedicated appliance, but also some hardware development kits) to a workstation via SCSI. Just saying...

That's OK though if you use it for peripherals only, not mass storage. Which is what I was using it for. Scanners and some specialized lab equipment with SCSI interfaces.
