  1. Regular console BASIC could not access the extra memory. So with that all you have is the 16k that is really the memory native to the video chip. Extended BASIC gives you access to the 32k. Under that setup you have about 24K of space for actual program code, and almost 14k of space for things like variables. That 14k is within the memory native to the video chip. So out of the 32k, you get 24k for program code.
  2. I find it interesting to compare Coleco and TI games given the same video hardware. Something like Q*Bert was done so very well on the TI. The programmers there went that one extra step to have the main character made up of more than a single sprite, giving him white eyes with black pupils and a black detail at the end of the nose, which adds so much to the main character. The coleco version had a single colour sprite with the eyes and nose having transparent parts that looked odd.
  3. Maybe actually finish off a game I've been working on for (ahem) 36 years now? I had posted my first real updates to it here (see link) in 2014. I had done more work on it since then but life got in the way. My next "real" work on it is to get working on a compiled version of it.
  4. By itself, the machine is a very closed and limited box. But as soon as you add memory and something like the FinalGROM it opens up beautifully.
  5. Honestly, I'd love a full size TI 99/8 machine, even if the entire innards are a raspberry pi, but if it looked and acted like a TI 99/8, complete with all external ports, I'd be thrilled and happily fork over cash for that.
  6. I assume everyone has looked over at the Colecovision version of Time Pilot. Given it uses the same video chip as the TI, it shows what could be done.
  7. There are compound reasons why both BASIC and Extended BASIC are slow on the TI. For example, although a bit more involved than what I'm about to say, your program is being interpreted twice before it is actually executed at the machine level. What Extended BASIC does though, is give you access to far more of the machine itself. Prime example is sprites, which can be set into motion and not have to be constantly updated by your program. XB is a must have, it's an essential cartridge.
  8. Well, it wouldn't really be something I'd hook up to my existing TI, since what I have always wanted is a fully functional TI 99/8 with all the hexbus peripherals. I like "real" iron, never been one for emulations. So having a physical /8 setup would be awesome.
  9. Getting a major "Threshold" vibe. This was a game on the Colecovision. So if it can be done on that, it can be done on the TI (given the same video chip used on both machines).
  10. So, completely out-of-left-field question, and given that it sits solely in the video chip socket I suspect the answer is no, but...... For things like switching the sprite limitation, could there be a way to do that via a keyboard combo? Or running a small utility on the TI that could do it when you want to switch? In other words, any way of pushing a change to a setting via the console that would not require adding a physical switch or hooking up to USB?
  11. Which console do you have? If the black and silver one, is the power led coming on? It's right next to the switch at the front right corner of the machine. If the beige console, I don't think it has a power led so it could be harder to tell if the console is actually getting power.
  12. Even just a variation on TOD would be cool. Maybe find a way to implement the "in room" battles in a 3D way? It could still be turn based, but just a switch-up on the visuals.
  13. Bosconian! I have this cartridge for my MSX machines, but always wanted it on the TI. And the TI voice synthesizer would be a natural for the in-game speech as well.
  14. For "utility": Extended BASIC For "game": Tunnels Of Doom
  15. PLA is cheap and cheerful. It's also easy to use and is more than sufficient for most purposes. If you tweak your printer settings really well, you can get impressive results. A bit of filler and sanding can also give a decent surface for painting over. I have not gone down the route of using other filaments since some, such as ABS, need a controlled environment that usually entails enclosing your printer to prevent drafts and heat variations.
