+acadiel Posted December 15, 2022 Share Posted December 15, 2022 Brought to my attention by the person who helped with the CC-40 MAME emulation: https://github.com/palazzol/PIC70x1_TMS70x2_dumper For example, all the CC-40 and TI-74 and peripherals have TMS70xx ICs with either 2K or 4K onboard ROM (I think the only 4K one is the CC-40+ and TI-74). My video controller has a socketed 2K TMS7000 series, which should make it easy to remove to try this (once I verify the unit works). (By the way, the video controller is just a Hexbus VT-100 terminal that outputs video to a TV. You control it by using device #40 and OPEN, PRINT, and CLOSE statements in BASIC. Or the appropriate assembly commands. To move the cursor around, use chr$(27) plus VT100 escape codes. - Stephen Reid) 4 Quote Link to comment Share on other sites More sharing options...
