Sord M5 is a computer with hardware that seems close to MSX1s. It was released in 1982 in the countries such as Japan, South Korea, UK and Czechoslovakia with localized character set and keyboard. The UK release was called CGL M5 after its distributor CGL (Computer Games Limited). Later the low cost versions called M5 Pro and Jr. were released.

The (big) power supply is external.

Run Sord M5 software on MSX

Sord M5 software can't run on MSX without changes. No loader is available and no software was converted.

The differences between the Sord M5 and MSXs are:

  • Memory map
  • BIOS
  • Z80 CTC (software are probably difficult to convert to MSX because of this CTC)
  • Used I/O ports
  • PSG is a SN76489 instead of AY-3-8910 (noise generator is on a separate voice)
  • Controllers
