A simple 0 STO c will do.

But can't you just clear memory by the usual procedure, i.e. turn off, and while holding down the backspace key, press ON. Does this work or not?
If pressing ON does not turn the device off, what about a simple one-step program with the OFF command?

I cannot force a MEMORY CLEAR by pressing ON and backspace.
I can turn it OFF by pressing ON, but not ON again.

I found this link: http://www.archives.hp41.eu/documents/sav-hp.pdf
I saw that there was an instruction (HP-internal) with some steps where one would press:
ON, ENTER and <--- simultaneously 10-12 times. In the next step there was a CAT 5 test. If that command does not complete one was supposed to send in the 41CX for repair. I am at that stage now.

Does somebody know how to reset the 41CX given the facts at hand?
