The Triton PC64 is a very rare MSX1 computer, it was released by the British company Radofin Electronics and manufactured in Hong Kong.

The function keys F1 to F8 are on the left and the right of the spacebar, what's unusual for the MSX computers, while F9 and F10 are missing. Many other keys are at strange positions. It seems to be a pre-version of the MSX1 computer.

There is no MSX logo and the advertisements indicate a Microsoft Triton Operating System with CP/M capabilities, 512 characters graphic set, 7 peripheral ports, 4 video resolution modes, 64kB User RAM, Z80A 8 bit processor, selectable 40 or 80 columns mode x 24 lines, 16 colors, 3 sound channels and remote control cassette.

Available peripherals were the 4 Color Printer and the Dual FDD. The feature allowing to choose 40 or 80 columns is available under CP/M.

Some below details are based on Dragon MSX-64, they need to be confirmed.
