Description
The Sanyo PHC-28S was aimed at the French market. However the keyboard is QWERTY instead of AZERTY as would be typical for the French market. This model is based on the MPC-5.
Contrary to the Japanese machine, this computer has an expansion bus slot: it can be used as third cartridge slot with an adapter, which was original meant for the MEB-01 slot expander, which in turn can be connected to the MPC-X, a Graphic Expander Unit which adds a MSX2 palette, high-resolution, superimposing, still function and zooming and supports a lightpen. Note however that Sanyo has never released the MPC-X in Europe.
This machine has been officially released in France by S.F.C.E with 16kB RAM in the first instance then with 32kB. The German company Olympia has released the PHC-28 with an AZERTY keyboard.
