I got a TI 58-c calculator a while back but there was no transformer
with it... I was hoping someone would have one and could give me the
specs on it and if it plugs into the calculator in either rotation...
thanks, bob laag

I don't know if the -C is the same, but my TI-58 (no -C) requires
6.2V ac @ 200mA. There are rectifier diodes in the calculator so
the supply can be connected either way round.
There is, or was, a website with all the details of the TI58/9 series,
including circuits etc. google should find it. I'm afraid I didn't
keep the url after downloading the info I needed :-(
PS Just found it: http://xgistor.ath.cx if it's still active.

I just checked my TI-58C, and it does indeed take a 3.3VAC 500ma power
pack. The links I posted earlier agree. The connector is keyed. The
part number is AC-9131. Are you sure that's the right pack, Stan? The
references say the TI-58 uses the same AC-9131 pack.

I had to go and find it* first, but the wall-wart definitely says
6.2V / 200mA Model AC9900/H-UK and is the one that came with it
when I bought it new way back when. The connector is keyed, but it
didn't need to be, the supply is definetly ac.
I've got it on charge now, and it still works fine - it's seen a
lot of use, it's on it's 3rd battery pack!
* Searching had the useful side-effect of my finding my Sinclair
Programmable Calculator, I'll get a battery later and see if that
still works.

According to these:
http://www.rskey.org/detail.asp?manufacturer=Texas+Instruments&model=TI…
http://www.rskey.org/gene/hpgene/tiadapt.html
...the output of the AC adaptor is 3.3VAC at 500ma.
