Hi Al
So, do you still need the CD?
Also, my friend may have some manuals. I don't know if it is just Solaris stuff
or HaL specific.

Operator error on my part, didn't know about "drvconfig" and "disks" since I've
never used Solaris 2.x before.
I may be that the 300 required some special init sequence to the processor. It
seems like I recall that it needed to do a scan to initialize a couple of
values. This may make it not work on a Sparcstation 5. I don't recall if we
shipped units with this problem or if they made a rev of the

It has been spoken for and now I feel bad now that I don't have more to give
away
to everyone who spoke up.
IBM created the 8" diskette as an inexpensive and reliable means of
loading microcode and shipped the first read only drives in 1971.
Memorex did ship a hard sectored R/W drive some time in 1972 likely
because Alan Shugart had jumped ship from IBM to Memorex. Some sources
credit Shugart with
I'd be interested if Doug isn't.

Hi Chuck
I agree it is easy to convert but I am surprised that a start-up would have the
guts to change the "standard," whether it was Memorex, Potter or Century. I
think before the 33FD Memorex was the market leader but I could be wrong. I've
asked some SA founders the question. Does
Doug Crawford has one of these, he may want this.
