How much were they/how much are you asking? ~CJ On Tue, Jun 5, 2018 at 9:05 PM, J. Alexander Jacocks via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
All,
I just picked up, at the Manassas, VA, hamfest, a pair of new-in-box Texas Instruments 99/4a machines. Both boxes are a bit scuffed and dusty, but one still has the factory tape on it.
I opened the other box, since it wasn't taped, and looked at the contents, which are definitely factory new. The computer was in a sealed bag, which I opened to check it out. The PSU and RF modulator are in their cardboard wrapper, which the adhesive has failed on.
So, I decided to keep one machine. I checked the PSU, and the voltages were within 1VAC on both the inputs, so given that they are internally regulated, that should be close enough. Via RF adapter, I get a grey screen, at power up. Via a homemade composite video cable, I get a stable tone, and a black screen.
So, two questions: 1) Does anyone want a new-in-box, untested, TI 99/4a beige model? 2) Does anyone know anything about fixing TI 99s? I'd like to go through the one machine and figure out what's wrong.
