  1. That's a good idea and if I can get the computer working I'd probably rather use it with a composite cable than the RF modulator anyway.
  2. I'm wondering too, and I know this a loaded question, is this thing even worth trying to repair? I'd like to play with it, but if it's going to cost a lot of time and money to get it going maybe I should keep a look out for another one in better condition. Is it generally pretty straightforward to repair a TI-99 with some basic soldering skills and access to some testing equipment?
  3. No beeps. No symptoms other than nothing appearing on the tv. I'm using the original RF modulator set to channel 3. I opened it up and took quick look inside. Confirmed only 2 wires connected from the port to the internal power supply board. The board looks like the QI board as per the photo at http://www.mainbyte.com/ti99/hardware/power_supply.html. I don't know the voltages of those capacitors so I just closed it up for now. Looks like this computer has just become a project.
  4. I just picked up a TI-99/4A on ebay. (Never owned one before.) It doesn't power on. If I hold the power brick up to my ear, I can hear a faint humming which seems kinda normal-ish to me. Looking at the power port on the back of the computer, I see only 2 pins where it looks like there should be 4. Does this look right to you?
