Capacity
- A nnK expansion adds nn Kbytes to the internal 64 Kbytes in the CPC. So the resulting size is nn+64 Kbytes.
- This does in most or all cases also apply on the CPC 6128: only 64 Kbytes of it's internal memory are used (the 2nd half of internal memory is disabled and replaced by the expansion RAM, the resulting size is nn+64, not nn+128 Kbytes)
