FRAM71 for HP-71B, short update - Hans Brueggemann - 06-10-2012
just a short update on my FRAM71 project:
updating the HP-71B from 1BBBB to 2CDCC is fully working now. thanks to Garth Wilson for pointing me to the forth module's CMOVE instruction for copying the system ROMs into FRAM, saving me a lot of time during last days' testing!
can anybody share a hexdump of the HP-71B's system diagnostic ROM? i am currently doing compatibilty tests on the FRAM71, and would like to test that one as well.

I can't take credit for that one, I haven't had the time to play with my Forth module much yet. Unless I have a twin I don't know about. :-)
