Connects one CS/A65 expansion card to a Commodore 64 expansion port or beneath a PET's socketed 6502.

The C64 revision 1.0C is marked okay and publishes Eagle files, but it works only with the C64, not the C128, and a fitted CS/A card can conflict with long video or IEC plugs. For PETs, revision 1.1A was tested only in a CBM 8296 and had power and clearance problems. Later 1.2A and 1.2B layouts add 3.3 V power and more mounting options but are explicitly untested. A working 8296 Ethernet stack is documented. usb65 later lists PET plus adapter plus NetUSB 1.x as tested, although the older NetUSB page says its single PET-adapter test was not fully working and suspected a supply problem. Treat that USB path as experimental. No current assembled seller was verified.

Build itChecked Jul 25, 2026SCSI-64 Project Familyby Andre Fachat

Adds SCSI disk hardware to a Commodore 64 through a CS/A adapter, with experimental external IEC-drive variants.

Only the modular C64 CS/A adapter plus CS/A SCSI card combination is reported tested and working. The simplified combined C64 board was not fully checked. VC-SCSI 1.0's component boards were tested separately but not as a complete drive, VC-SCSI 1.x remained an idea, and VC-SCSI 2.x was preliminary and untested. The published FAT12/FAT16 filesystem software is explicitly early beta and may corrupt a disk; never test it with valuable media. No current kit or assembled seller was verified.
