HP 41CV problems

[nhkader]

Hi Karl,

I've tried the SIZE command. It cannot recognise 319. It's like my CV has lost its expanded memory and also some of it regular registers. Look like the NVRAM has lost their mojo.

I tried to key in the program but clearly something has gone wrong with my processor board. I tried to key in RCL IND Y but once I complete this program step it reflects as RCL IND T. Strangely if I do STO IND Y that is encoded correctly. Something is a bit wonky with my processor and memory board is all I can say. I will try to do the MEMTEST on my simulation of the i41CX on my iPhone to see how it works.

I fear my calculator could give me unreliable results hence I have elected to change the processor board and already purchased another one.

If all this fails, I will then upgrade to a CL.

Thanks again
