Only the amount of space that can be used to read/write defines the CPC class. EPROM space (read only!) doesn't influence the CPC class.

Serial / network I/O is disregarded, because it works independent of memory and disc space. However a letter can be added to define communication device classes.

*Class A CPC: Communication with up to 19.200 Baud

*Class B CPC: Communication with up to 38.400 Baud

*Class C CPC: Communication with up to 76.800 Baud

Example: A 6128 with two disc drives, 512 KB expansion RAM and an serial interface from Amstrad would be: Class 5A.

This concept was developed by [[TFM]] of [[FutureSoft]]. Please do not change CPC classes without previous discussion and agreement, since other pages of the CPC Wiki point to this definitions.

Class definitions of CPC's

The CPC computer range can be devided in different classes. This makes sense to tell in quick which kind of CPC and hardware-expansions are needed for a certain application. This definitions are taken from the FutureOS handbook and must kept in agreement with that please to omit confusion.

Defined memory and drive space classes are:

  • Class 0 CPC: 64 KB RAM, no drive (CPC-464)
  • Class 1 CPC: 64 KB RAM, 3" drive (CPC-664)
  • Class 2 CPC: 128 KB RAM, 3" drive (CPC6128)
