It's the ultimate 8-bit machine: 7 MHz (*1) Z80-compatible CPU, 512K main RAM, 128K video RAM, FM synthesis (OPLL), MIDI, adjustable speed autofire on space bar. Full specs here .

(*1) The original Z80 took 4 ticks for even the most basic instructions, more unless paired with fast RAM. The R800 in the turbo R can do them in 1 tick. So it's a lot faster than what the clock speed would suggest. For an 8-bit machine, that is.

While I still have it wired up, I must admit that I only really start it when doing research for the openMSX emulator. If I want to play old games, I do it in the emulator: it is just more convenient with save states, reverse, cheats etc.
