AMR SCSI

I was playing with an AMR SCSI card and was wondering if there was a later version of the EPROM, I have V1.2.

I was hoping that there might be a version that allows more than two partitions

I'm not familiar with that

I'm not familiar with that one and there is nothing about it on the Apple II Documentation Project.  Can you post a pic?  Any information you have?  It may be something worth preserving since it doesn't appear that there are any archived manuals or anything for it.

Thanks for posting that here!

Thanks for posting that here!  It looks like a very  cleanly desgigned card unlike the CMS one I have.

I wonder if those PALs are

I wonder if those PALs are locked.  I bet they probably are.  It uses the common AMD 5380 kind of SCSI chip, similar to the one the CMS cards and the ones Apple used on the early Macs.

There also doesn't seem to be

There also doesn't seem to be anything on the Cirtech Insyder SCSI card which is even simpler than the AMR

Thanks for posting that.  It

Thanks for posting that.  It is another 5380 based card.  This one using the original NCR branded chip.  I think AMD and at least one other company cross licensed the design.  This one is very compact, only one 74LS chip and it looks like one PAL but I can't read the markings on it.
