Sony
Hit-Bit 75

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...


 

Very good and reliable computer, my first home computer ever. The cursor keys were good, but they fail about time because the switches used by Sony, but nowadays are easy to find replacement.

You can connect a disk drive to *ANY* of the cartridge slots, same as on any MSX, not specifically 2nd slot...
