WTB: TI-99 Modem Power Supply and Keyboard

Recommended Posts

Hi all,

 

I'm trying to put the finishing touches on my "maxed out" TI-99 setup. All I need is the power supply for my TI acoustic coupler modem, and I'll be done.

 

Does anyone have a spare they'd be willing to part with? The model number is 901017, output is 20V AC, 400mA. I've heard it's the same as the one used on the Atari acoustic modems. I'd also consider purchasing a second modem with power supply, if someone has one they'd consider selling.

 

I also have a second TI-99/4A console, but the keyboard is damaged (broken keyswitch and missing keycap). This is one of those earlier black keyboards. I'm looking to either repair the keyboard, or just swap in a fresh one. If anyone has a parts keyboard, or just a spare, I'd be interested in negotiating.

 

Any help is appreciated. I'm including pictures of the modem power supply, which is apparently somewhat unusual.

That one is pretty hard to find (at least with the TI part numbers). The only Novation power supply I saw on eBay that even comes close had a 24VAC output. . .Keyboards show up on eBay pretty regularly, but they end up costing almost as much as a console. Whatever you do, stay away from the keyboards that were manufactured by Mitsumi (the board underneath the assembly will be a light brown). They used a membrane to establish contact, and those did not withstand the test of time. All other keyboard types are OK to use (green boards of various types).

So in the month or so since I posted it, I actually managed to find a loose adapter for the Atari version of the modem. Should be a direct swap in, right? Same voltages and all? Nope, looks like either Atari or TI (I'm betting TI) swapped the barrel connector to make their box proprietary. Oh well, still on the hunt for one. I'll find it eventually.

 

 

I have several TI-99 keyboards if you need one. Let me know which one you are looking for. I have 3-4 different types.

Sorry for taking so long to get back to you. Yes, I'm still interested. I need one of the original black style that was first used on the 4A. I don't know much else about variations beyond that, but I can look at what I have if you need any more information. How much would you want for one?
