Fitting a 3½" Disk Drive inside your Amstrad CPC 6128 or 664.
This is a little more difficult than fitting an external drive.
Reasons :
- the ribbon connector inside the CPC has to be slightly split because although it's nearly compatible, it's shorter (less number of pins) and the last few pins of the pinout don't match, they have to be shifted.
- the power connector has its colour convention reversed, to double/triple check voltage before connecting your drive to it, or you'll connect 12V to the pin expecting 5V and fry your drive.
- Ready signal issue, maybe?
This is based on content available on:
- Short guide, 664, few photos Retrofitting a CPC 664 with a 3.5" drive (ParaDOS recommended for full capacity)
- Longer guide, 6128, better photos CPC6128 Parados and Internal 3.5" floppy drive mod
