This is a quite popular MSX 1 computer. As soon as it was available (in Europe at least), a lot of extensions were already available too, making the HB-75 a quite complete system. It is also a quite well designed computer.

There's a built-in piece of software (Personal Data Bank) available on startup and composed of an agenda (scheduler), a memo, an address manager and a transfer utility. And you could save your work via a special RAM cartridge.

There is a ROM of 48 KB : 16 KB for the integrated software and 32 KB for the Basic. The RAM is composed of 64 KB and 16 KB for the video. You can connect a disk drive controller to the second cartridge slot which is at the back of the computer, the primary cartridge slot being on top.

Foreign models where named HB-75F for France, HB-75D for Germany or HB-75P for PAL models...

Tack för en mycket trevlig radiosida och framför allt serviceinstruktionen till min Radionette Autofon AF 2, har nya nålar och snart ska den igång.
