Thanks to a fellow listmember, I found some fuji 7502's which my programmer will program, and are identical to the signetics 82S129, $5 bucks each. I also found some signetics 82S181's, which are the 8Kb proms for HP microcode boards for $6 each. No luck finding 82S141's though. I'm happy now :) Thanks to all who replied! Jay PS - I also found a stock of 2114 rams :)
