HP-41CX mistake(?) installing HP-IL module

[TASP]

Appreciate that tip there. I installed an HPIL with the I/R module installed and locked up a machine a while back too. I didn't have anything irreplaceable loaded so wasn't too worried about Memory Lost. The first battery pull or 2 didn't do anything but the third (or forth?) did. Each time I tried it, I left the pack out a little longer. Didn't get a Memory Lost, but was really annoyed with ME for making the error in the first place.

I think there was a module you could make that was described in an old PPC Journal that had a button that would pull an address line lo (or high) or something else entirely, and it would do a soft reset more effectively.

I'm not eager to go looking, but if I do the HPIL-I/R tango again I'd better think about it.

If the 'soft reset' thing looks like a tried and true 'feature', might consider putting it internally in my HP41CX #3 project . . .
