| The Hitachi MB-H50 is an MSX1-compatible home computer released in 1984 by Hitachi in Japan. It was part of Hitachi’s MB-H series of MSX systems and was a slightly lower-end model compared to the MB-H70. The system adhered to the MSX1 standard, which defined the architecture and compatibility of early MSX machines. It used a Zilog Z80A compatible CPU running at 3.58 MHz. The MB-H50 came with 32 KB of RAM and 16 KB of VRAM. The video display generator was the Texas Instruments TMS9918A, which provided graphics modes typical of MSX1 computers, including 256×192 resolution with 16 colors. It had one built-in cartridge slot on the top and a keyboard with a standard MSX layout. The keyboard included a numeric keypad, which was not common on all MSX1 machines. The system offered composite video and RF output for display, and a cassette interface for loading and saving programs. It supported standard MSX BASIC, stored in 32 KB of ROM. The MB-H50 was primarily intended for the Japanese market and had limited distribution elsewhere. No built-in software or unique features beyond standard MSX compatibility were present in this model. |
