The Hit-Bit 55 was a classic MSX1 computer. It was very similar to the Hit-Bit 75. Its most distinctive sign was its flat but good quality keyboard. It was one of the few MSX with the Philips VG-8000 to have a low-cost keyboard.
Unlike the HB-75, it had only 16 KB RAM. There was a built-in software (scheduler and memo) which was a kind of cut-down version of the one built-in the HB-75, program size was only 8 KB against 16 KB on the HB-75, it seems that some version had the 16 KB version though. To save files made with this apps, a 4K S-RAM non-volatile cartridge was used (called HBI-55).
The Hit-Bit 55 was clearly marketed as the low-range MSX model of the Hit-Bit serie. It was also available in a red and black cases.
