Sanyo MBC-555

Sanyo MBC-555 (1982)

The Sanyo 550 & 555 were the first MS-DOS compatible computers that retailed for under US$1000. It was also quite possibly the only (somewhat) IBM-compatible system that was actually slower than an IBM PC (the PC clocked at 4.77 MHz, while the Sanyo clocked at 3.6, giving it a Norton SI rating of 0.8).

it's the only IBM clone that runs at a lower speed than the original: 3.6 MHz instead of 4.77 MHz. It has a matching keyboard with reset-button on it. The board includes a pin out on which a 5 MB hard disk drive can be attached.
