I'm certainly not a Mac guru, but ISTR that Macs up through System 6.x
or so could copy single-sided 3.5" disks, which would make a Mac the
appropriate "bridge" machine for getting this disk onto a 3.5" double-sided
format.

And yes, Pascal low-level formatting is identical to ProDOS formatting.
But Chameleon can copy *files* from one file system to another, not
just disks (preserving the existing file system).
