Why not CF for Vic20 too...

The number of pins is correct.. maybe it works out of the box?

25 years later, and we find that the Apple II and VIC-20 are fully hardware compatible.

Has anyone actually tried this on the VIC-20? I don't know nearly enough about the VIC-20 or the Apple II to know if this even could work but if it did that would be wholly remarkable.

I am convinced if you plug this thing "as-is" in your VIC, you are likely to simply fry it.

This however, does not mean that it is impossible to make it "VIC compatible". Perhaps a simple rearrangement of the pinout would do the job.

and while your at it fixing this for the vic20, also include an 3k-16k ram expansion+switch and there is a need for a reset switch to...

There is the uIEC and 1541-III, both of which would work perfectly on the VIC. They emulate disk drives for maximum compatibility.

A cartridge-based system would be a lot more challenging on the VIC, because as d0c points out, you need reconfigurable 0K/3K/16K+ memory, plus BLK5 for cartridge images...

Such a project would become the VIC-20 version of IDE64, connecting an Harddisk or a CF directly to the expansion connector of your C64. Nice project but completely 1541 incompatible. Programs using their own IEC routines and circumventing the ROM for this reason simply don't see this drive.
