The Daewoo CPC-50 is a MSX1 console with only 8kB RAM. It has been released by the Korean company Daewoo in 1986. It was available in pink/white. All MSX-compatible consoles from Daewoo are called Zemmix that 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. Two other revisions have been released, CPC-50A and CPC-50B. It comes with a massive AC power adaptor including a power switch. Each revision has a different mainboard and a different power supply adapter.

Do not use the power supply of CPC-50A or CPC-50B on the CPC-50!

The CPC-50 is a MSX1 console that does not use a MSX-Engine. The CPU is a Z80A from Goldstar (GS Z8400A PS).


  • RF output
  • Analog sound & Composite video
  • 2 general connectors (Joysticks, Mouse, Paddle controllers, etc)
  • 1 cartridge slot
  • Power supply input: +/-19V and +9V (8-pin DIN type 8A)


In emulators, this console can be easily converted into a MSX1 computer with keyboard, second cartridge slot, etc. However, Hangul BASIC is not available, as there is only one ROM in this machine: a slightly modified version of the BIOS+BASIC rom.

After booting, you come to an empty black screen, just like on the Sega SG-1000 console. It's an illusion! By default, you are in SCREEN 1 with COLOR 15,1,1. Just enter COLOR 15,4,7 to get the classical SCREEN 1 screen.

You will also notice that the system does not provide any 'Ok' message or MSX-BASIC info text, the cursor is invisible and the content of the function keys is empty. All these tricks are just to make think that it's a game console!
