Things I've Built

PIC PIN/Pad (using PIC2550)

A vendor was not forthcoming in providing a sample of their TDES DUKPT pinpad; in frustration I said "I can probably just make one with spare parts in my junkbox"; then I did just that. It was later handy in proving bugs in the vendors' product.

DL13-C

Frankencalculator; re-brained HP12-C with crypto functions. Actually, this is incomplete. I got it running as an emulator of other HP calculators in the 10-series, but I got distracted with other projects. I hope to come back to this one day...

Well, thank you! And I second your suggestion about creating a 'retrocomputing' list -- actually that suggestion of yours is how I stumbled across your profile.
