  1. Since it has 1.2 roms, it is likely an older motherboard (rev 5 or lower). If so it will need an adapter for newer ROMs. I can't recall if there is more than one type of adapter or if they are all the same for the lower rev motherboards.
  2. There is also the Meanwell RPD-60A (Digikey link), as discussed in the thread below. In my build I de-soldered the Meanwell input and output terminals; I then soldered the Atari terminals to the Meanwell board. AC side: DC side:
  3. From what I could tell it takes the ROMs and GROMs and converts them into a format that is consumable by the compiler. The architecture may be genius, but it sure is unreadable.. the bulk of it looks to also be (computer) generated code. First few lines of what is generated from the TI ROM: /* automatically generated from rom.bin */ const unsigned char rom[] = { 0x83, 0xE0, 0x00, 0x24, 0x83, 0xC0, 0x09, 0x00, 0x83, 0xC0, 0x0A, 0x92, 0x30, 0xAA, 0x04, 0x60, 0x02, 0xB2, 0x00, 0x08, 0x1E, 0x00, 0x04, 0x60, 0x00, 0x7A, 0x1E, 0x00, 0x04, 0x60, 0x00, 0x78, ...
  4. Not sure if emulation is your thing, but you can always go laser + a daisy wheel font: Daisy wheel font above (by Volker Busse) is attached. I always imagined it to look more like courier, but there was probably more than one look. Daisy Wheel.zip
  5. TI Basic as a scripting language on Windows, Mac, Linux: https://github.com/abbeyj/ti99basic This runs the TI Basic ROMs in a GPL virtual machine on the Windows/ Mac/ Linux host.
  6. The FinalGrom is able to run grom images. It’s probably the simplest hardware solution. Otherwise it can be done using an emulator. @ralphb has a gpl assembler which will produce cartridge images which can be used in the FinalGrom or in an emulator.
  7. I found this nice retrospective on our favorite computer https://www.howtogeek.com/731558/a-successful-failure-the-ti-994a-turns-40/amp/
  8. New release Changes: - Resolves the issue reported by Elia, where the game displays "I don't understand" after a valid command is entered. The input routine doesn't allow repeating keys. This is when the same char repeats when a key is held down. There was a (bug?) that allowed ENTER to be repeating when the key was held down.

  9. These are the latest binaries. The only differences here to the last set of files are: - title screen text has additional credits - the system reboots on exit from the game INNUH-TI-EN-40.zip INNUH-TI-IT-80.zip INNUH-TI-IT-40.zip INNUH-TI-EN-80.zip
  10. It appears that the game is functional after this happens. What I think I will do is open an issue in the project, so that the bug is documented; I will keep looking to see if I can reproduce the issue. For now I will make a pull request to Davide, so that he has the code as well.
  11. Thank you I will take a look at it edit: does the bug happen only in the white room? I think there are some known issues in that room. See here https://github.com/DarwinNE/innuhs_pyramid/issues/2
  12. I cannot seem to reproduce the bug. Here is the output from my game, in Classic 99. Anyone else able to reproduce the bug?
  13. Thank you @Elia Spallanzani fdt I would be happy to look at the oddity that you are seeing. It would be helpful if you could tell me what commands you wrote in the game. Also, I want to add some acknowledgements to the game. I would be grateful if you or someone else could check that my google translated Italian looks ok: English to be added to title screen: C version ported to TI99/4A by Chue Xiong 2021, and uses libti99 by Mike Brent (Tursi). Italian to be verified: Versione C portata su TI99 / 4A da Chue Xiong 2021, e utilizza libti99 di Mike Brent (Tursi).
  14. New versions: 40 column English 80 column English 40 column Italian 80 column Italian The 80 column version requires 80 column capable hardware (F18A). Each is in a zip file. You will have to use option 5 to load one of: INUTIEN40 INUTIEN80 INUTIIT40 INUTIIT80 Tested and seems to work in classic 99... Not tested on real hardware.
