I’ll look into getting a set of JMP proms. The local shop had 82s131 at $10 each but listed as refurbished, so a good chance they are already programmed with something. They also had 82s130 with open collector, which could probably be made to work with pull ups, but I might take a couple of tries to program and the effort of building a programmer.

I have RAM, 8154D, 8060N, and TTL so apart from the PROMs just need to order a set of switches and rig up a display until I can retrieve those from my Mum’s.
