Hello all:
Last week I got a toshiba T-100, with two 5.25" disk drives and a
monochrome monitor. It starts up with Basic.
Anybody knows if this system can run CP/M?
Another question: I own an IBM system 36. It has two hard disk drives,
105 MB each, and a tape cartridge drive. Could anybody tell me if these
drives are SCSI?
Thanks in advance.

I picked up a copy of D.P.I. s Print Director MS manual. Looks like
a neat peripheral-access controller device. Anyone have any need for
this ? No disks.

Heaven forbid I ever insult anyone's choice of OS. :-) The gist of my
comments still stands, and I think it's highly appropriate to this
list: without an established mechanism for the preservation of the
rights of old software, or some process of stewardship of archaic
software, computer collectors are often violating the copyrights
of others.

I can argue with that. What about upgrades? If bought XYZ v1.0,
then paid a special price to upgrade to v2.0, I don't have two copies.
Technically, the company doesn't allow you to resell v1.0 as its
own package. It's true of many of today's packages, and I'm sure
it's true of any old mainframe/mini OS license, too.

I thought the list might be interested in the feeding frenzy occurring at
eBay ( http://www.ebay.com ) over some Altairs and associated
hardware/software. This is going to be very interesting to watch. The
Altair 8800a is up to almost $500.00 in just twelve hours.

More information on the Altair auction items. They have (finally!) all
been posted to www.ebay.com
in the Hardware:General section. Most of the items have been posted, but
a couple have not. If you
are looking for a particular item, check the list below, the URL for each
of the items is listed.
There have been several requests for copies of some of the items. I don't
have a way to copy the disks,
can anyone help out with that? If you can, please let me know.
Feel free to e-mail me with questions.
Thanks again for your patience and support.

I've got my old Amiga 1000 in the basement, with a serial number in
the 30s. Circa 1986, it qualifies, no?

Circular?
Believe me, I gave it strong consideration.
Purely to determine the efficiency of image manipulation in Java.
Oh yes, to show off as well, I guess.
I thought better of it, and went on to write emulators of my Soviet
Calculators instead.
;)

In fact, there are some useful things you can do to ACTUALLY recover
on computer running a reasonable operating system. Back in the late
60s and through 1981, Oregon State University ran an operating system
(called humbly OS-3 (short for Oregon State Open Shop Operating System
or OSOSOS)) but I digress.
OS-3 ran on a Control Data 3300 which had been fixed to actually
conform to the Control Data specifications for User/Supervisor
operation. The operating system was written to be as reentrant as
possible; all OS code (but a very small part pertaining to interrupt
dispatch) was PURE (not self modifying.) This is noted, since the
standard subroutine call (as was common those days) altered the
first instruction of the subroutine to be a JUMP back to the calling
code. I.e. there was no "stack" mechanism in hardware.
Since the monitor code was not self modifying, the OS could at boot
time compute an exclusive-or checksum for itself and save it for the
occurrence of a parity error. Parity errors only reported the memory
location of the error, not the actual value read. So when a parity
error occurred and if it was in the monitor reentrant section, the OS
could recompute the value of the bad location by exclusive-oring
all the OTHER locations together and then exclusive-oring the computed
monitor checksum. This reproduced the contents of the bad location,
it was stored back at the address indicated by the parity check
hardware and the OS resumed from the parity error interrupt.
Of course, for user programs (which were seldom re-entrant) the OS
just aborted the program with an error and went on about it's business.
Consequently, the parity error interrupt was RARELY fatal (at least to
the system at large. Individual users did occasionally complain when we
had a memory stack that started to go bad, but didn't get bad enough
to find with the overnight diagnostics.)
This was all back in a day when ECC did exist, but it was Horribly Expensive
(and this was compared to memory that cost about 1 to 2 dollars per byte.)

Keep an eye open as finding another VS2k with more memory than the one
you have is more likely. VS2ks are pretty common. Besides you can then
use the short memory one for spares. They are also a fun little vax. I
have three here, one running VMS, one diskless (mopboot)
and one running ultrix.
They can hold up to 14mb, with the 4 and 8 mb cards being the most common.
FYI: VMS 5.4 will run in 2mb (slowly as it will swap it's brains out).
With 4mb and a RD54 it makes a fine single user system with DECwindows
support.

there are several things on that disk including versions 5.4 through 6.1
