Programmable ?

Postby TI-88 » Fri Feb 26, 2010 11:59 am

Hi!

The following sequence of keys should be able to demonstrate the ability of a HP 41C to be programmed.
It is the case on my 41 CVs, but not on the 41C, I would like to know what is going wrong here.

Keys ----> Display
ON+CLX ---> MEMORY LOST
PRGM ----> 00 REG 46
GTO .. ----> 00 REG 46
LBL alpha AAA alpha ----> 01 ASHF :?
SIN ---> ROM :? :?
R/S ---> ROM
PRGM --> 0.0000
PRGM ----> 01 ASHF
SST ----> PRIVATE :shock:
BST ----> PRIVATE
GTO .. ----> 00 REG 12 :o
LBL alpha BBB alpha ----> 01 ASHF :?
COS ---> ROM :? :?
R/S ---> ROM
PRGM --> 0.0000
PRGM ----> 01 ASHF
SST ----> PRIVATE
BST ----> PRIVATE
GTO .. ----> 00 REG 12


And so on, I can't enter any program....
Any comments, gents (and ladies ;) ) ?

There are others who know far more about this than I, but I'll jump in anyway since there's not much traffic on this forum. The 41C should work the same as the 41cv in what you are trying to do. The exception I can think of (if there's not something wrong with the unit) is if you got a special-purpose one with a take-over ROM or something like that. I understand there were some made that way for employees who were not to be doing any programming but rather only use software supplied in the machine.
