Only just within the last month I finally obtained a ROM dump from a production HP-01, for
potential use in my Nonpareil simulator. Previously I only had the preproduction code
listed in a US patent. I'm not sure when I'll have time to actually work on the
simulation, though.
My original plan had been to crack open an HP-01 module and try to read the ROM bits
optically, as Peter Monta did for the HP-35. However, that didn't work, probably due
to a passivation coating on the ROM dies.
