I became the grateful recipient of a TI Programmer today. A buddy at
work said "here, you like calculators, right? Better than throwing it
away." Well, I said "thanks!"
Now, in looking about the internet for some info on the battery styles
for these things, I have a couple of questions that I cound't find the
answer to.
This calculator has a battery pack called BP-8 which has 2 AA ni-cads
and a small circuit in it. It connects to the calculator internally
with a connector that would also mechanically mate to a 9 volt battery.
Now I would not expect a 9 volt battery to work where 2 AA's work, but
I'm not sure. In looking at Gene's web site he says the BP-8 is also
used on the TI-30 and I see TI-30's on ebay saying that they work with 9
volt batteries.
I will replace the two AA's with new ones. That should make the BP-8
good again.
I guess the is a roundabout way of asking for some background on the
power requirements of this calculator. Unfortunately my buddy had lost
the AC adapter (apparently it was an AC-9132, thanks Gene!). So I'll be
looking for one of those. 5.7v, 240ma, and that small 2-pin connector.
Thanks for any help.

Well, after a little more searching, it appears that the circuit inside
the BP-8 battery pack is a step-up circuit to generate 9 volts. But
I'll wait to hear from someone here with actual experience before I hook
up a 9v battery.

My TI programmer has (and works well with) a 9V battery (the battery
compartment door shows a picture of a 9V battery) and just a hole for where
the charger goes.
Is the connector for the charger part of the BP8?

Yes, the connector for the ac adapter is part of the BP-8, as is the
cover to the battery opening. There might have been a plain ole battery
cover at one time for this one, but it was probably discarded when the
original owner started using the rechargable pack.

Dave,
I had a NIB TI programmer and it could use regular 9V batteries or the rechargeable
NiCad pack. I don't remember if you could use the AC adapter when the standard 9V
battery was installed but I think you could. I'm not sure if it had a separate holder
for the 9V battery but I don't think it did, I think you just pulled out the NiCad and
put in the 9v battery.
I've been meaning to E-mail you. I moved the MDS to Leesburg last week. I looked it
over, it looks like it's in pretty good condition except that it's filthy. The
internal drive is connected to the card in the back so it's set up as SSSD. The only
card in the MDS is an 8085 CPU card and the only card in the expansion is an FM controller
but I expect that you have plenty of cards for it.

I had a NIB TI programmer
There were TWO "TI Programmer" calculators!
Please identify WHICH when talking about them.
The first used LED display. It went through batteries almost as fast as
you could put them in, and a charge lasted at most hours. But it worked
GREAT when plugged in.
The second used LCD display. The batteries last a LONG
time! Unfortunately, the keyboard seems to not last as long as a charge
of the batteries!

I have one of those on my desk, the 9V battery in it is least 6 months old and
still good, I dont use it all that often but a couple of times a week. The
fact that the calculator goes asleep (display goes into standby in ~30
seconds, calculator powers down in several minutes) helps

The rechargeable pack of mine would not hold a charge - a replacement
might be in order. And with disposable batteries in it, I've had it go
dead in a shorter time than one of my long work sessions.

HMMMM!
My LED (early model) one did NOT go into standby. THAT difference between
yours and mine would be enough to account for it.

My LCD one does shutdown. But the flaky keyboard is not as nice as the
LED one (when it's plugged in)
