I've heard that the TI 99/4A computer monitors were actually Portacolors with no tuner....how true that is I'm not sure, but they sure do look a lot like one. That would take it up to '85 or so if you count them.....

Nice find, and that's a WEIRD control panel!!! Definitely one of the last ones of the Gen I style, and I see it has a 10VADP22 in stead of the hated 11SP22.
The only later model of the Gen I style, is one I saw which was solid state, and had click UHF. I think by '81, they went to the smaller cabinet with the pocket type handle, and with Hitachi-inspired board ("AB-B/AB-C"), and dropped "PortaColor" in favor of "Performance". Charles

Nope,
The monitors for the TI-99/4a where a 13" made by Zenith and a 10" made by Panasonic that was a rebadged pro monitor. The TRS-80 Model 1 used a monitor made by RCA, Apple II/III monitors where made by Hitachi or Samasung, the IIgs monitor is Mitsubishi. Commodore monitors are JVC and can be driven with S-Video with a 4 pin din to dual RCA adaptor.

I think I remember reading where the solid state AA chassis came out sometime in '77 to replace the tube-type HE chassis. Of course, they could have continued production of the tube chassis for a while longer in order to use up old stock and I'm sure the tube version was offered at a lower price than the new solid state model. Years ago, I saw an early AA solid state set that used the same tuning knobs as the tube portacolor. The later Ax series sets used more modern tuning knobs. The newest tube portacolor that I've actually had my hands on was made in late-'76 and I've heard many reports from reliable sources that some '77 models exist. If any newer models exist, I'd love to see one.

Somewhere I have a service bulletin from GE dated sometime in '77. It is headlined something like "Goodbye HE, Hello AA!", stating that production had ended on the tube chassis and begun on the new one. But, I've seen several reports of the old one being built as late as '80. Nobody ever seems to have a photo, though. I have to wonder if this is just a case of people confusing the two models.

It could very well be confusion. I know the solid state Ax series was around for several years. BTW, didn't GE make a 15" tube set that used an inline CRT and a portacolor style chassis.

Someone here mentioned a 13" Zenith monitor perhaps used on the TI99 computer system. I have one of those monitors and it is a Zenith "System 3" unit in almost new condition. Can I trade it for a 1966 Porta-Color??
