Yes, the Universal Disk Converter (it was/is on Asimov somewhere,
UDC.DSK) by Gary Charpentier (sp?). Allowed conversion to/from ucsd,
prodos and cpm. It also allowed filecards, something chameleon doesn't.
I gather it was written in Apple Pascal 1.2, from what else is on the
disk. I once managed to email Gary, who said he had released the source
but no longer had a copy himself.
