*Class 1 CPC: 64 KB RAM, 3" drive (CPC-664)
*Class 2 CPC: 128 KB RAM, 3" drive (CPC6128)
*Class 3 CPC: 128 KB RAM, 3" drive, 2. drive: 80 tracks, doublesided (DS)
*Class 4 CPC: 320 KB RAM, 3" drive, 2. drive: 80 tracks, DS
*Class 5 CPC: 576 KB RAM, 3" drive, 2. drive: 80 tracks, DS
*Class 6 CPC: 576 KB RAM, 3" drive, 2. drive (80 trks, DS), 20 MB hard-disc
*Class 7 CPC: 576-2048 KB RAM, 2-4 internal and 2-4 external drives, hard-disc with at least 20 MB
*Class 8 CPC: 576-4096 KB RAM, 2-8 drives, hard-disc with at least 20 MB
*Class 9 CPC: 576-4096 KB RAM, 2-8 drives, hard-disc with at least 128 MB
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.
'''Defined communication classes are:'''
*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
*Class D CPC: Communication with up to 100.000 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.
