SIMH images to Zip Disks

I'm drawing a blank on the exact model number but it's the one that does disk only and not also tape. It could be CDU-720... that does ring a bell. It's got firmware on it that the '11 executes when you enable the ROM and then jump to that from ODT. That firmware provides a user interface for configuring the card and each of the target devices as well as the means to then boot from a specific device. I use that user interface to ge it to boot from one of the ZIPs. I wonder if anyone has attempted to archive the firmware and PALs on these SCSI cards? I have a second card that was injured in a horrible accident (I plugged it into the Unibus, justified the wrong way... so, it was off by two in all the edge connectors. This promptly fried the card because the +20V core voltage ended up in all the wrong places. That was the quickest $300 I ever burned. It was however, educational. I've since repaired most of the damage, replacing buffers, burned traces, etc. however a couple PALs were affected and need to be replaced. I am chicken to take them from my working board and try to read them out unless there's a high likelihood it can be done. Or, if they've already been read, then I could just burn new ones from the images and try them. For some reason, I've put most of this whole event out of my mind :-) Chris -- Chris Elmquist
