So I just opened it up and <surprise> it's
got an Intel 4004 inside!
Does it contain the other related chips (4001 ROM, 4002 RAM)?
Unfortunately, I'm not able to test it out because it requires a funky
squarish three prong power cord. I'll have to look around and see if I
can find one.
This machines is the sort of thing you don't just power up!. It's
sufficiently rare, and the chips are also rare (4004s are difficult to
find, the ROMs with the right code in them are presumably impossible to
get) that you _must_ find a way to test that power supply on a dummy
load. Get the 4004 etc data shsets to work out vhat voltages to expect (I
can dig these out if you can't get them any other way).
If in doubt, stop and ask. This sounds like a very interesting machine,
and it would be a great pity to do damage to it.
