hp41cx - Annex memory not recognized

Postby francois » Wed Aug 31, 2011 8:33 pm

Hello,

I'm new on this forum and I'm starting working with my 41 cx, I've a problem with annex memory :
Without any Xmemory module :
After a memory lost :
CAT 4 indicates a lot of strange names of files :
******* @.000
_______ @.000
EMROOM indicates 0 (instead of 128 I think)
SAVEP indicates NO ROOM

If I insert 2 Xmemory modules :
EMROOM indicates 474
SAVEP works
cat 4 return always stranges names

I think this could be a bad memory chip on the board or a bad solder on a DIL8 chip
but which one ?

best regards from france
