Topic: HP-67 ROM Simulator
On the site see page "New & Upcoming" a link to the new version of my HP-67 ROM simulator with card reader.
I worked with E. Smith in December 2007 and January 2008 and I finally made it.
A problem was to understand enough the handshaking between ACT & CRC to make work a simulation of the Card Reader for Data and Programs.
It's done. It can read and write "cards" to/from the java applet window.
Articles will detail the micro code later.
Stay tuned.
