PRGM mode doesn't work on HP-25 Message #1 Posted by jbssm on 18 Jan 2006, 8:38 a.m.
Hello all,
I have this HP-25 that is in very good cosmetic condition and as all the keys working, but there are some strange problems with it.
1 - The STO and RCL keys work, but I cannot recall what I've saves in the registers, I always get an 0
2 - In PRGM mode, I can write my program, and it shows the steps like it should, but when I try to RUN it ... nothing, I always get an 0
Can anybody help me fixing it?
Regards,
Jorge
