Yes, but they are only PAL16L8 unregistered devices. They should be straight
forward enough to analyse unless they are utilising the feedback from the
output pins to the fuse array.

I made a list of all the components (but forgot to bring it with me today :-().
They were all pretty standard (6x 74HCT240, 74HCT245 and a few smaller 74LS
chips) apart from the RAM (4016 - an NMOS version of the 6116 2k x 8 RAM chip)
and the NCR5380 SCSI controller.
