Survey Pac usage

Programs for HP-41

Survey Pac usage

Postby kburr » Mon Mar 25, 2013 7:21 pm

I have recently reinstalled the batteries (they had been out for a long time) for a HP 41 CX with a Survey Pac. When I go to use the survey programs (xeq Trav or Curve) I get XROM littleT (like an exponent) and either TRAV or CURVE as a response. It should be asking me for input at this time. What can I do to make it work correctly.

I'm not sure what could be causing this glitch, but the problem is either in the calculator or the ROM module. Have you tried running it in another HP41C? If it works there the module is OK. If not, maybe the ROM got corrupted somehow.

You could try copying the ROM programs into calculator memory and then reading the program (and executing it) stepwise in program mode, to debug it. :?
