Daewoo CPC-51

The CPC-51 aka Zemmix V (V for Victory) is a surprizing MSX1 console with its aerodynamic design and its interchangeable wings. The power supply is integrated in the unit. It was released by the Korean company Daewoo in 1988 and was available first only in red/black, then a second release offered 3 different color versions. All MSX-compatible consoles from Daewoo are called Zemmix which means 'It's Fun'. The MSX logo does not appear on this machine, because the absence of keyboard makes it not fully corresponding to a MSX computer. We can therefore speak of a hidden MSX! This machine has only one cartridge slot and it's not possible to add a keyboard, although there were plans to allow such an extension on the underside of the unit: no such keyboard has however been released for this model. The CPC-51 is a MSX1 console that does not use a MSX-Engine but a custom IC DW64MX1 that includes the 8255 PPI, slot select circuitry, a memory mapper and various glue logic. The CPU is a Z80A from Goldstar (GSS Z8400A PS). The main RAM is present on slot 0-2, a configuration that can cause poorly written software to crash. Also, with this layout, the POKE-1,(15-PEEK(-1)\16)*17 trick to workaround buggy software that does not handle subslots properly will cause this machine to freeze. This machine also has problems with sound playback from cartridges containing sound chips, such as the SCC. This is because the SOUND IN pin on the cartridge slot is not connected.
