The Sanyo MPC-200 is an MSX1 home computer that Sanyo sold in Spain in 1985. It is the Spanish version of Sanyo's Japanese MPC-2, with a Spanish keyboard that includes an Ñ key, two cartridge slots and the power supply inside the case.[1] The MPC-2 was first shown at the Japan Electronics Show in October 1985, and the same design was also sold as the Sakhr AX-170 and AX-230 in Arabic-speaking countries and as the Fenner FPC-500 in Italy.[5]

Hardware
[edit | edit source]The top of the case carries the two cartridge slots, labelled "Double slot system", the power lamp and the reset button; the cassette socket and the two joystick ports are on the right-hand side; the printer connector, power switch, mains lead and the RF, video and audio outputs are at the rear.[6][7] A label beside the slots tells the user to switch the computer off before inserting a cartridge.[7]
The CPU is inside a Toshiba T7775 MSX-Engine, a surface-mounted chip on the underside of the main board that combines a Z80-compatible CPU with the other MSX1 functions apart from video and sound.[3][8] The video chip is a Toshiba T6950, which Sanyo's manual calls a TMS-9929A equivalent.[1][2] Inside the case the mains transformer, labelled PT0129, sits at the back left beside a fuse marked F101, T1A 250V. The main board is marked UF063481 and MCL437F, and a separate board marked SANYO EB1402 sits behind the cartridge connectors.[9]
The T6950 video chip
[edit | edit source]The T6950 supports all the documented screen modes of the TMS9918 family but not the undocumented "mirrored" modes, so a few games and demos that use them do not display correctly. Its colour palette is also slightly different from the Texas Instruments chips.[10] Neither is a fault in the machine.
Power supply
[edit | edit source]The MPC-200 has its supply inside the case and is rated at 220 V, 50 Hz and 6 W. The Spanish label on the base says not to open the computer without first disconnecting it from the mains.[4] A photograph of an opened machine shows a mains transformer with a fuse beside it, and two large electrolytic capacitors next to a part on a heatsink.[9] The mains lead has a two-pin European plug.[11]
Documentation
[edit | edit source]Sanyo's Spanish operating instructions are hosted here as Sanyo MPC-200 Operating Instructions. They give the specification, a list of precautions and a table of problems and checks, but no circuit diagram or pin assignments. No service manual for the MPC-200 or the MPC-2 is held in the MSX Archive's collection of service manuals or on the Internet Archive.[12]
