"Karin Maxi" was an Atari 8-bit drive made in Poland by "Karin". Basically
it's WD1772 + 2 KB driver ROM + 360 KB or 720 KB drive from a PC. It works
as a "new device". The interface may be on a cartridge or built into
the computer. No slow SIO, no need for additional CPU (Atari's 6502 does
all the work), up to ca. 20 KB/s transfer - simply an 8-bit user's dream.

Not from Atari disks.
You may need e.g. to read whole 512-byte sectors from PC 360k disks,
but on "Karin Maxi" this can't be done using built-in SIO driver (you have
to program WD1772 yourself). Some other Polish drives ("TOMS") can also read
PC disks, and they use normal SIO - unfortunately I don't know how to read
512-byte sectors on such drives (probably you just use PERCOM commands
'N' and 'O').
Bye,
Piotr
