CPC 464

The Amstrad CPC 464 was one of the most successful computers in Europe. More than two million computers were sold. Despite its ordinary characteristics (like those of the Sinclair Spectrum and often less interesting than those of the others like the Commodore 64 or Atari XL/Xe series) or odd features (like video memory or strange floppy disk format), it was very popular because of its really low price and its interesting commercial concept : all peripherals were sold together (like the Commodore PET that was sold years earlier): CPU/keyboard, tape recorder, monitor (monochrome green or colour).

A huge number of programs and peripherals were developed for this machine. It ran AmsDos (Amstrad's Operating System). AmsDos was completely embedded in the Basic using so-called RSX commands starting with |, but it could not format disks, you needed a special application for that.
The 464 also could use CP/M 2.2 or 3.0 when used with an external Floppy disk unit (3" Hitachi, 180 KB / face). A lot of great CP/M software was adapted for the Amstrad CPC.

About 42 KB RAM was available for the user, the video memory and the ROM were mapped on the same addresses with a dedicated chip to switch the memory banks automatically.

Notice that the first Amstrad CPC prototype (called "Arnold", which gave the name ROLAND (Arnold acronym) to several CPC games) was built around a 6502 processor and then changed to a Z80 late in the computerís development. A few months later, the CPC series would be completed with a computer which offered a built-in floppy disk unit: the CPC 664.
