Title: Anyone wanna sell a Texas Instruments TI-99/4A Computer?
Post by: mr_lou on 18:42, 27 September 13
I have a mate who'd like to join me and my other mates in our retro gaming evenings. He used to have the Texas Instruments TI-99/4A, so our current mission is to find one of those for him.

I don't suppose anyone here would happen to have one lying around they'd like to sell? It has to have the European PSU, be in fairly good condition and such. It also has to be the black and silver version, rather than the beige version.

eBay has several. Like this: http://www.ebay.co.uk/itm/Vintage-Texas-Instruments-TI-99-4a-Computer-/271282956889?pt=UK_VintageComputing_RL&hash=item3f29b96a59 (http://www.ebay.co.uk/itm/Vintage-Texas-Instruments-TI-99-4a-Computer-/271282956889?pt=UK_VintageComputing_RL&hash=item3f29b96a59) .


I always really liked how this machine looks, I think I've got one somewhere...

Yes, there are plenty on eBay, but the majority of them are not tested, or says something along the lines of "worked fine 30 years ago when I put it on the attic". No thanks.

But yes, there's one auction ending on monday that I'm watching.

Yes, they were definitely sold in Australia. Been a fair few for sale on ebay AU over the years...do not see them a lot these days but they do pop up.
Currently on ebay Australia someone is selling 32 cartridges for the TI-99

Yes, they got to Europe, and it has to be a European model because the US PSU takes 120 volt.
It also has to be the black'n'silver version.  :)

Not interested in cartridges at this point. He'll start up slowly, trying to load games from WAV files first I think. Then try to find a nanoPEB or CF7+. Like most other retro machines has a flash-card solution nowadays, the nanoPEB and CF7+ is the TI-99/4A's Compact Flash solution. Getting one of those will be an much bigger challenge than getting the actual machine though.

There are a few European TI-99/4A's on eBay at the moment that I'm keeping an eye on. So we'll see.

Hmm okay. I was having a look at the Aust. eBay too and found someone selling their 99/4A from the US happy to ship it to Aust. Naturally it was 120v 60hz. Could that be made to work here or Europe do you know?

I not sure if it's worth asking about this on the Vintage Computer Forum (http://www.vintage-computer.com/vcforum/forum.php), which is based in the US, there seems to be a few sites which are dedicated to the TI-99/4A, and one of those appeared as if they were selling those machines. Unfortunately the site (http://www.shop.texintreasures.com/) was under repairs.

I don't have one but I do have a ceramic + gold pins TMS9900 processor (the one pictured here: http://en.wikipedia.org/wiki/File:KL_TI_TMS9900_Black_Background.jpg (http://en.wikipedia.org/wiki/File:KL_TI_TMS9900_Black_Background.jpg)) and all the chips needed to make a complete TMS9900 system (ROM/RAM/clock generator, UART, I/O chip and many more).


My father trained to be an electrical engineer in the 60s/70s and bought the complete set to build his own system (from a magazine guide, I believe), but then got married and never found the time to assemble everything. He did tell me the processor cost him £70 when he got it, and in 1976 that was a months wages for him (though I'm not sure how accurate that really is)! I've always wanted to build something based on it, and give it to him as a present, but I've never figured out exactly what I could build that would actually be useful. Of course, I've no guarantee that the chips haven't long since been destroyed by static.

We're interested in the black'n'silver version.
How's the condition? Can you attach some pictures here? (Preferably showing that it's working)
Has it been in a smoke-free home?
Title: Re: Anyone wanna sell a Texas Instruments TI-99/4A Computer?
Post by: BluesBrothers on 21:17, 30 September 13
The 2 I am selling are both boxed and in good cosmetic condition and I will upload photos tomorrow when I've "hopefully" finished thorough testing. All the TI's I have are the silver and black variety TI-99/4A.
I have already had some interest via PM for one of these and Mr Lou obviously wants one so if anyone else is interested I'm afraid both are temporarily on hold but I will let you know if either (or both) decide against taking one

If you don't smoke yourself, you should be able to pick up any smell of smoke quite easily. If you do smoke yourself, you won't be able to quite as easily.
Would you say that the machine(s) smell of smoke?
(I don't know how picky my mate is, but me being an ex-smoker I'm one of the worst in that regard.  ;) )

Have given up myself earlier this year (though I haven't smoked inside for many years) and whilst my sense of smell is improving it is not great still. If anything the machines just have that old smell. I will strip each down and give a deep clean so regardless of where the machine might have once been you'll never know. I can't promise rose petals and apple blossom but it won't smell of fags. :laugh:

Quote from: mr_lou on 05:34, 01 October 13That sounds great. You have a lot of experience with electronics?
Well I'm not an expert but I do alright. I consider myself to be very thorough (which Corifoot will vouch for since he's had to listen to me drone on ::) ).

I have now finished full testing you be pleased to hear and both machines have passed through a "deep soak" test with flying colours. I'd like to give a clean to each before sending images but I will endeavour to get that done today all things being well.

Very nice pictures indeed.

Just to be 100% sure, this is only one of the machines, right? I'm asking, because I see two different years on two screens shots. First 1980, and then 1981.

My mate will be viewing the pictures within the hour. Looking forward to hearing what he'll say.

Can you please PM me which of the items on the photos you're including with the offer you made?

Yeah, it's the same machine, the years are the release dates for software.

I'll post images of the 2nd machine after lunchtime today. Was hoping to have it done already but have been landed with kids till lunchtime so the chances of getting any work done are next to none existant ::)

That also looks very nice. To be honest, I'm having trouble seeing what the big difference is between the two.
Apart from the accessories of system 1, which we will need though. Is the price difference because of the accessories?

Am just having difficulties uploading shots of just the computer but when I have you will be able to see that the aluminium is quite as pristine as on the first one especially when you enlarge or even supersize the photo thumbnails. Let me try and get these other images on and then we can chew the fat about price, condition, accessories, etc

Not exactly. Just that the first one was more expensive than the 2nd one. And then he suggested a price for the first one. Don't know about the 2nd one yet. So nothing 100% definite yet.

The monitor output of the Ti99 is a bit of a pain. Certain cartridges were very common (I think they came with a few cartridges thrown in) and can be found very cheaply. Other cartridges go for a lot more. Ti games only work on that machine and no other machines games will work on it.

The machine itself is easy to find, but finding one without damage / dents to the metal plate isn't that easy.
