Rainbow disks are readable on a PC with 1.2M. But, it's sometimes a
little easier if you use a 720K 5.25" drive.
96tpi, 300 RPM with 250K data transfer rate
(or, with some 1.2M drives: 360RPM with 300K data transfer rate, but NOT
double stepping as would be done for 360K disk at that data transfer rate)
There are commercial programs available for the PC to read/write Rainbow,
and even programs for the Rainbow to read/write PC 160K/180K disks.
(for writing PC on the Rainbow, start with a virgin disk, and format it on
the Rainbow in PC format, or in a PC using a 1.2M drive in 190K format
-same track width problems as rewriting 360K disks in 1.2M drive)
