Sega G80 Vector Development Kit

New games written for a vintage 1982 vector arcade machine

• Follow the development progress on YouTube shorts
• Not emulated, not MAME, no Raspberry Pi, no Teensy, no ESP32, no kidding.
• Runs as it would have in 1982 on the original Sega G80 boardsets
• Runs on a Zilog Z80 at 3.86712 MHz, less than 32KB ROM and 2KB RAM
• Integrates with the Sega XY vector coprocessor (a two board set of 74k logic)
• Programmed bare metal C
• Loads and works with 8035 CPUs on the sound and speech boards
• Burn directly to 2716 ROMs and run in the real game
• Can also run without hardware, just copy over the StarTrek MAME ROMs
