I am confused, just get a scart cable and a scart to hdmi. Done. Scart supports a bunch of TV image formats (composite, svideo, rgb etc..). In

All the TIs, Amiga, Amstrad, etc... Work ootb. You can find those converters for a few bucks on ebay. If you want to get fancy buy yourself an OSSC to get a really good image quality.

I was a young adult when the TI-99/4A hit the market. I worked in the digital communications industry and considered getting one, but I ended up waiting for something better and comparably priced. I put together a Ferguson Big Board II a few years later. Many of you might say the TI was "better", and you would be right about the CPU and the color graphics, but not about the software availability. CP/M was the best "business" OS of the day until MS-DOS eventually overtook it. It still makes me sad to think about what Bill Gates did to Gary Kildall.

Not to denigrate the post, but the TI-99/4A did color out of the box; this post is talking about a modern adapter board to work with a modern display instead of TI's proprietary monitor or a TV. I know because I first programmed on a TI-99/4A and we didn't have the space nor free connection to hook it to the living room TV, so I used a 13" B&W TV in my room for years before ever seeing the color that it was capable o…

It's still amazing to see an image coming out of the TI-99/4A without any ghosting or other analog artifacts.

It was years into my computing journey before I saw such a crisp display. It always throws me for a little bit of dissonance whenever I see a TI-99/4A on an emulator or here with a VGA output going to a LCD display.

Yeah, that is beautiful.

Props to you. The TI-99/4A was my second -- and longest childhood -- computer. Getting one working again so perfectly warms my heart. Fun fact about the TI-99/4A: It was actually fast , sporting a 16-bit CPU in an 8-bit era. The BASIC interpreter was slow because it, like many TI-99/4A programs, was written in a sort of interpreted bytecode that could live in video RAM/ROM. The CPU itself had access to only 256 bytes…

You sound like you know a bit about TI-99s, so let me ask you this: Do you have any idea why they made the lower case character set be small upper case letters instead of real lowercase like the Apple II or C64? A couple of years ago I did a Sunday morning project of inserting the Apple II font into the TI-99 ROM to run on an emulator, and other than having to shift the j's and g's up a pixel or two it worked beautifully.

Wow, what a coincidence: I, too, first programmed on a TI-99/4A, mostly with the small B&W TV in my room, for the same reasons. I saw the color output on one we had at school, and at a friend’s house, but I outgrew the machine before I ever got my own color TV.

Count me among those whose first computer was a TI-99/4A. Learned so much on that little machine, esp. hexadecimal with the way sprites worked. Extended BASIC cartridge was a must have. I wrote so, so many half-finished game programs on that thing.

That brings back memories. Parsec was a great game.
