3??�?" & 5??�?" Disk Drives

Besides the "big" brands' disk drives for the Amstrad CPC, there were also user solutions and garage company made disk drives for the Amstrad CPC.

These usually came without their own DOS, or you had to replace the built-in AMSDOS with a DOS like ParaDOS or a patched AMSDOS.

But even without a special DOS taking use of the higher capacity of those drives, the use of such drives made sense, as media were much cheaper than 3" media.

Today, with supplies of 3" disks draining and company solutions no longer being produced, a self-made 3 1/2" disk drive is the perfect supplement for every CPC user.
