A friend gave this to me, he found it in a stash of scrap boards

Do you know what this card is/does?

Its a SCSI loop-back test card. Sorta common, usually alway one on eBay at any given point. Not sure how its used though. By the way, the card is better identified under "077-0219". You will find lots of test gear numbers start with 0.

It's part of the AppleCAT diagnostic set.

How do you hook it up? I see two macs in the photos

Do you have the software that comes with it? can you make an image?

thanks again!

If that is the Bus Master card in the AppleCAT kit, I have two of those. Never seen the loopback card, though.
