32 sector 8 inch floppies

[Barry Watzman]

Re: "I just found a box of about 15: 8 inch floppies 32 sectors (hard
sectored) Double Sided Single Density. Some are TDK F1-H.  Any takers?"

These are used in the Processor Technology Helios disk system (intended for,
but not really specific to, the SOL-20 computer).  I have what might be the
last two such operational systems in existence, and I have to say that
carefully because they have not been powered since 2004, when they were
working and booting PT-DOS.  However I have several boxes of the diskettes
and don't really need more.
