    This was my first computer ever. My dad got it for me in 1993. I think he paid $10 at a thrift store with a bunch of games. I still have it. Not the best computer ever made, but for me it brings back cool memories.

      @@fractalMD Yes it still works! I still have it. I have the FinalGrom99 for it so I can play all the crazy "16 bit" games! I have so many other retro computers, this one doesn't get used as much. I try to use it at least once a week though.

    There's always joy getting stuff to work (and it sucks losing the footage). The TI99/4A is a lovely machine. I typed in an Italian text adventure onto an emulated one, and did an opening scene for it too in Extended BASIC.

    I had friends who had TI-99/4A computers BITD. I was a C64 kid. As an adult I tried liking the TI-99/4A computer, got myself a nice boxed unit, a bunch of cartridges, etc and in the time I owned it my thoughts were it was better than the VIC-20 but not as good as my Commodore 64, so I sold it off. Side note, I love your Galaga t-shirt Taylor. Galaga is a long time favorite arcade game of mine.

    This is the exact condition my TI is in one day after I got it. It powered up ONCE, but no keyboard at all. Then the screen went blank so I tore it down and reseating the socketed chips and got video back. Now I am in the process of fixing the membrane. I need a silver conductive pen I believe because the header traces are flaking.

    Great video (as usual)! I had a friend 3 doors down who had a TI-99/4A (although either black keyboard). We would visit each other to try games and BASIC programming between the Coco and the TI. A year or two later when I got my first Coco BBS up (1983), a different friend got one up on his TI-99…, and that had the huge “sidecars” of cards (speech module, modem, 2 floppy drives)… it was huge! (I didn’t have a multipack on the Coco yet to compete…lol).

    Love the sound of that keyboard. You could probably put out a typing ASMR video with it🤣. Great job on this machine. When I first saw the keyboard I thought it was going to be one of the cream coloured plastic machines so was surprised to see the brushed metal version as I always thought they came with black keys only.

    Finally! I've been waiting for you guys to do a video n the TI-99/4A ever since I saw it on the shelf in your Tandy 100EX video. It was my first computer growing up and even though it has the better style of keyboard (without the mylar membrane) it also has issues. Just curious as to why you guys went with a BackBit Pro cartridge as opposed to the FinalGrom (other than they are very scarce right now). I am looking forward to more videos but you'll find out that if you are going to program in basic, go with a memory expansion and Extended Basic. Much more powerful. And check out PixelPdeant's videos on the TI, lots of great information.

    • @TaylorAmyShow

    The first computer I got to see was a Ti-99, but I'm sure it had a flat keyboard. It was on a shelf alongside an Atari 400, also with a flat keyboard, and an Atari 800. I was most interested in the 800 because it looked like a typewriter. I think that it was about £650 ($1200 dollars in 1980). I looked around to ask my dad if I could have it, and saw him walking away with some urgency. Thinking back, I guess he saw the price tag.

    that isn't the keyboard for the older black/silver TI-99/4a. that keyboard goes to the newer beige/tan TI-99/4a. that particular type of keyboard has had lots of issues over time. the black keyboard was a lot more reliable. I actually have the opposite of a new beige/tan Ti-99/4a with the older black keyboard because my beige/tan keyboard that came with my newer beige/tan ti-9/4a was beyond repair so I jut replaced it.
