What's new on my site? :

I started the HP-67's ROM exploration, in collaboration and with the help of Eric Smith :

A Java simulator is running the HP-67 micro-code saving & loading data and program from text files, simulating magnetic cards.
You can trace the R/W routine and study how the Card Reader Circuit (CRC) is cooperating with the firmware.
