have yet to plug it in. All of the software I do have
is hard-sector
HDOS... no CP/M whatsoever. I thought I had it, but apparently I don't,
IIRC I haev HDOS on hard-sectored disks and CP/M on soft-sectored disks...
unless I missed a box. I have already contacted Don
Maslin off list to
request a soft-sectored Magnolia CP/M boot disk, and check my thinking
here... it should be possible to create a bootable hard sector disk from the
bootable soft sectored one by installing both controllers. Unless I'm
missing something, that seems like a no-brainer. If that is in fact
Yes, that should work.
possible, I will be happy to share the benefits of
that (small) labor with
those in need.
One unfortunate rub since my earlier discussion in this thread with Tony...
last night I pulled my reference machine out of storage and powered it up,
and it almost boots. Almost. A working machine went into storage six
months ago, but what has emerged seems to take a (hard sector) disk read
error on every modulo-10 numbered sector starting at 40 (that's sector, not
track), with any diskette I use. No problem with any other sectors, just
Very odd...
You might try checkking the index monostables on the hard sector
controller (they only really do anything once per track, when the index
hole between the sector holes comes round), but I can't see why it would
then work for the first 4 cylinders.
I am really digging into the depths of my memory here, but IIRC there's
some RAM on the main CPU board used as a sector buffer, and it's 2114s. I
might well be thinking of some other machine though. If there _are_ 2114s
for this, then check them. As you know by now, 2114s are know for their
unreliablitiy...
