UCSD P-system could only allocate contiguous disk space. So a disk that had
become "checkerboarded" by writing and deletng files had to be defragmented,
using a spplied utility called "Crunch".
Was that adequately protected against catastrophes caused by interruption?
Softech and UCSD Regents filed trademark registration for "XenoFile", and
listed it as a product, but as near as I can tell, NEVER sent out any copies.
(February 1987, I went to the Patent and Trademark Office outside of
Washington, Dc, and researched some trademarks, in preparation for my trademark
registration)
They also announced a "universal disk format" for ALL machines, but never had a
clue about how to do anything compatible with FM, MFM, and GCR.
