Sega
Teradrive

What a strange computer ! It was built by IBM (like the Atari Jaguar few years later) in Japan for Sega, and was sold only there.

It is an IBM PC AT compatible system mixed with a Sega Megadrive (Genesis) console. On the front panel, one can find a Megadrive cartridge slot, two joystick connectors, a reset button, a MD/PC switch, a volume slider, a headphone output, a power button, keyboard/mouse connectors (PS/2) and one 3.5'' disk drive.

Three models were released, a low-end Model 1, with 640k RAM and no HD, a Model 2 with two floppies and no HD and 1MB RAM, and the high-end Model 3, with one floppy, 2.5MB RAM and a 30MB drive. All three shipped with the same software and accessories.

Amstrad made later a similar computer called MegaPC.

It is said that this is a very reliable computer, I also remember hearing that it was pretty popular in Japan, it was never released in the US, it could use any accesories developed for the PC XT because it used the ISA standard, it ran a version of Windows, possibly 3.1, and MS-DOS
