HP 82106A memory module


Can anybody tell me how can I check if a HP 82106A memory module for the HP-41C is working?
Thanks a lot,


Set SIZE 000, then switch to PRGM mode, note the amout of registers.
Turn off the calc, insert the memory module, switch on, then go to PRGM mode, compare the amount of REGisters to the first one. If the difference is about +/- 64 registers, the module is working;-)




So you´re from Brasil. Maybe you´d like to know that there are around 6 very active HP fans in Brasil.

Me and other can help, either by phone or email.

Best regards,
