Hello,

does anyone have a ROM image of the Amtech RF512C drive? It seems to be
a 1571 clone.

I am asking because I asked someone to give me a ROM image that is
collected with M-R (cbmctrl download from OpenCBM), and the image looks
very "suspicious". That is, things are not at the locations where they
should be. The image "as is" would not even boot, because the RESET
vector is invalid!

Does anyone know if this drive has some "counter-copyright-detection"
measures? That is, does it really return the ROM contents on M-R in the
are $8000-$FFFF?

Does anyone know if that device has the usual memory map of a 1571
drive?

Regards,
Spiro.
