The NCR 53C80 was a really common chip, somehow I can't imagine it being *that* hard to source a replacement. It showed up in PC SCSI controllers fairly often in addition to Macs. Granted I haven't tried looking for one. (All the oldskool ICs I've purchased recently have been *really* widespread parts like small SRAMS and 6(5/8)00 series CPU and PIO chips.)
