MCODE EPROM HARDWARE

[MeindertKuipers]

Learning HP41 MCODE is an exiting process, and I had loads of fun (and a bit of frustration) learning and implemention back in the good old days, using DAVID assembler and a real MLDL (which I still have but do not use anymore). I remember a friend reading HEX codes while I typed these in an EPROM programmer, and having to do this a few times because of typing errors (including the wait to erase the EPROM).

Today I would start with the V41 emulator and HEPAX to make the first steps in learning how to program mcode. HEPAX offers great documentation and tools, while V41 offers tracing through your code, so there is less need to recover from lockups when you make a mistake.
