I heard that recently too, I think because I mentioned the 30 but I can't 
remember.  But on checking, I see there is talk of a rumor, but that 
there's no truth.  That would have been great back then, add a jumper or 
something and get a "Programmer" for 30.00 or whatever I paid for the 
TI30.

TI had a single board computer using their 990 microprocessor (the one 
used in the TI99/4).  And they used a TI calculator case to house the 
keyboard and readout for the board, a nice method of doing.

I remember decades ago the damage batteries would do to flashlights.

But I got a Grundig shortwave portable for $2.50 at a Rotary Club "Garage 
Sale" some years back, and the batteries had leaked (though I can't 
remember if the batteries were still in there).  But it turned out they 
just did cosmetic damage, eating away at some shielding but not at the 
circuit boards or parts.  I guess  it depends on how it was kept, the 
batteries were at the bottom so if it was standing up, most of the leakage 
would have left the radio through the battery cover.

I also ended up with a Casio musical keyboard that showed signs of battery 
leakage when I got it home, and I expected the worst, but while the 
plastic shows signs  of it, I saw no trace of the leaking on the 
circuitry.

I got a TI58 for five dollars in the nineties, and it came with the 
printer. That calculator was the one like the 59, except it didn't inclue 
a cardreader.
