I have a copy of version 6. It's on 1.2MB 5 1/4 disks. If you'd like an
eval copy, let me know.

I'd add tht at the time of the Rainbow and pro 80track drives were not

???? CP/M disks nominally start logical block 0 after system tracks.
Dos disk are different and I never paid much attention to them.
POS for the PRO was same media but file allocation was different again

I saw a stash of 3 or so AT&T 3B2 systems. Don't know the exact model, but
they are a common one I've seen before. They are a metal white case that
normally sits on a desktop. Approximate dimensions are 17" wide, 24" deep,
and 17" tall.
The scrap dealer said I could have 'em for $35 each. They are not in mint
cosmetic shape, one case appears a bit mangled. I have no clue what (if any)
cards or drives are inside them.
If anyone wants these as-is-site-unseen, let me know asap.

Ssssh... is this what are you looking for:

I really don't think that sharing this *old* stuff harms M$ bussiness.
Hope this helps.

Actually, it WAS called DR DOS as it used to be
owned by Caldera until 2003 (which was at one
time part of Novell). It is now owned by SCO and,
like most things SCO gets involved with, they
take ownership, drive it into the ground and then
abandon it like the group of a--holes they are.
Last official DR DOS release was 7.03 by Caldera.
SCO just wanted some of the pieces of it so they
can make more of the "we have rights" B.S. claims
that they make. SCO did absolutely nothing with
it once it was purchased from Caldera. There are
"unofficial" releases of DR DOS 7.04 and 7.05.
They are part of Partition Magic, Western
Digital, Quantum/Maxtor and Seagate/OnTrack
Diagnostics. 7.03 would be the last and easiest
to obtain. Versions .04 and .05 have pseudo-DOS
FAT32 support, but it breaks certain basic DOS
functionality and was actually customized from
the .03 version for obvious specific purposes
(drives larger than 80/120GB, etc).

I have been having some fun with Prime Numbers using FORTRAN 77
under RT-11 on a PDP-11. Since I rapidly run out of the capacity of
32 bit numbers (INTEGER * 4 NUMBER), I have started to use
64 bit values (REAL * 8 NUMBER) but the conversion routines
leave a lot to be desired on output. When using F32.0, I can count
on only about 15 digits of accuracy even though the values are often
accurate to an exact integer.
If needed, I can write my own conversion routines, but I though I
might inquire if anyone knows of any libraries which are exact or
better still, multi-precision libraries which can handle up to 128 bit
integers?
Can anyone
Sincerely yours,
Jerome Fine

I also have a Spanish version dated 12/90, some utils have been
updated, e.g.
- MEM (1.00 -> 1.01) now displays HMA contents.
- CHKDSK (6.14 -> 6.16) ??
- EMM386.SYS (1.2 -> 1.21) Windows 3.0 works in extended mode.
... probably some more, but I didn't check all of them.

I just acquired a Rainbow with ~10 boxes of disks.
Most are for DOS it seems, though some for cpm/86.
Could someone explain the differences between the
types of media meant to run on this puter, whether it
has to do with os, or physical properties (soft
sectored, hard sectored, RX50...). I also have access
to a crate of pro 350 disks, and would like to know
how to archive them. Is Teledisk or any other program
useful for any of this?

Now I'm not an expert on these, indeed I know nothing at all about apples,
but these look pretty weird to me - are they actually what they say they
are, and really common? eBay item 5219329581 (expensive as usual, so no
bids) for three linotype boxes, one of which has a disc drive with an apple
logo on it. (Listing has some larger pics linked from it).
