New Article: HP 41C Service/ Diagnostic ROM Versions - Allen - 03-10-2008
Greetings,
Despite the time change, I'm finally getting around to some articles:
Making sense of all the 41c Service ROM versions: 1A 1C 1D 2A 2B
Article Includes photos of three Service ROMs (2 live and 1 EPROM), along with advantages of each ROM and PDF version of Key-maps.
I am working on converting some Original HP41 DEMO programs into Bar-codes. Will post separately once complete.

Hi Allen,
Which one do you use typically?

I find the ET-11966 to be the most useful. My SM2A is hosted on an HHP Eprom box, which unfortunately limits it's utility since the card reader takes up Pages 4, E,and F- Most of the module tests that are added to the SM2A all default to Pages E/F for their test source.
Kind regards,
Al
