+acadiel Posted November 29, 2020 Share Posted November 29, 2020 Finally have my Tutor/Pyuuta the way that I want it. Took quite a bit of work to get to this point, and a lot of people to thank. - @tanam1972 3 D cartridge adapter with Japanese and US BIOS and Japanese BASIC - @tanam1972 Door Door, @AsmusrTI Scramble, @retroclouds TI Pitfall, and US BASIC cartridges - @jedimatt42 Cherry MX Keyboard PCB printed by @dhe, along with Matt’s keyboard bezel (printed by Damos Designs). MX1A key switches, Keychron key caps and four translucent key caps with custom labels. (We really need to get some custom MOD/MON and music note keys - the music notes are really \ and | ASCII codes.) - Modified 3 D cartridge adapter BIOS to support modern key layout for US BIOS - Custom built joystick adapter (with six 1N914 diodes on each joystick) - supports extra fire button on unused Atari joystick pin and two joysticks. - Rewired NES game pad to support Atari pinout plus one extra fire button - Removed Japanese RF modulator - Socketed and replaced two VRAM chips - Removed top RF shield and put two heat sinks on 9995 and 9918A Let’s do some more experimentation next! Figuring out mass storage and maybe translating some TI XB programs could be next! 3 Quote Link to comment Share on other sites More sharing options...

+dhe Posted November 29, 2020 Share Posted November 29, 2020 So are there any differences between a Tomy and a Pyuuta? What "keys" did you end up buying? Quote Link to comment Share on other sites More sharing options...

The only difference is the ROM/BIOS. The 3D cartridge adapter from @tanam1972 (order it from him on Twitter) can override the internal ROM and make a JP version a US one and Vice versa. The keys are from this key set: https://www.keychron.com/products/keychron-k2-keycap-set-1 Quote Link to comment Share on other sites More sharing options...
