I just checked my Sharp PC-1211 (which is the same
thing) and the
battery is almost dead - the screen is hard to read but it still
works. Given that I've had it for 20 years or so that's not too bad!
I'll pick up a new battery later today (should last another 20 years!).
I've been told (not checked it myself) that the original battery for the
PC1211/Radio Shack PC1 was 4 mercury cells in series, giving 5.4V or so.
4 alkaline cells give 6V, and the machine doesn't work correctly at that
higher voltage (it doesn't do any damage though). On the other hand _3_
alkaline cells are rumoured to work.
