How to make a custom HP-41 rom for the rest of us

[derekamos]

Gene, sorry I seem to have misunderstood you.

Programmers hold all the aces here, if your programming is up to par you certainly can achieve this. The simplest job here would be to complete a clump of the roms you wanted in a block of whatever size it all comes to. Without complex functions like bank switching, library 4 or card reader roms.

For a programmer, one completed job leads to the next in relentless fashion, as perceptions open as to 'how it could have been done better', only after completing it. Finding willingness to continue, as it can become like 'to hard to labour with', may rely on a good set of tools that you are comfortable using.

Hope this helps,
DA
P.S Didn't I see an Isene rom around? you seem to me to be well established already.
