these floppies?

I haven't, but it's clearly GCR, and the encoder/decoder circuit is very
similar ot that used in a Commodore disk drive (for example an 8050). I
have no idea if the encoder ROM cotnents are the same.

DO NOT USE DSHD (600 Oerstedt) disks with it.
They may appear to work fine, but will typically not be readable within a
few weeks.
DSDD will work, but 2DD (double sided, double density 96tpi) are best for
it.
