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

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.
