RE: HP 41C mod
I have an HP41CX with the magnet activated switch built in. I was able recently to get it back to regular speed (the magnet fell out of the port cover and is long gone).

I didn't do the mod, but I don't remember who I sent it to. Undoubtedly they advertised in PPC Journal.

Except for gronking the card reader, I don't recall any trouble with it at 2X speed, although it makes all the beep tones exceedingly shrill.

2speed HP41CX,int2XMEM+ZEN, HPIL+DEVEL, HPIL+X/IO, I/R, 82143, 82163, 82162 -25,35,45,55,65,67,70,80
