The 512K was a bit more challenging. Normally the 512K doesn't even support SCSI, but I have the MacSnap expansion board. Even though I came across some documentation that suggests there is actually termination power exposed on the board via the D1 diode, I couldn't trace that connection to VCC. So instead I added a new diode between VCC and the termpwr line. I added some glue to hold it in place and to prevent shorts.
