There are 3 connections to the main CPC464 P.C.B.
*Cost-down revision of the CPC464.
**Reason: The Gate-Array is of a different design and is soldered to the main P.C.B.
*CPC664 or CPC6128. **Reason: The Gate-Array and Z80 CPU are sited sit in positions which the SP512 can't connect to.
*464+ or 6128+.
**Reason: These two use a new design with an ASIC which is soldered to the main P.C.B. The SP512 can't connect to this.
