I know, this is completley off the wall, and odd at best. But are
there any surviving copies of v6, that ran on the 370? I understand
there were several ports, one running on UTS, another on bare metal
before AIX was ported...
Did any of these survive?
Bad luck. The CD's are lost (unreadable actually). Not surprising seeing as they
were old and had been tossed around so many times (sic).
Maybe the original request for Mach sources should be redirected to comp.os.mach
or to some of the original authors to see if they still keep something around.
It might be that even CMU keeps something.

This sounds like a Digital BA-11 of some sort. It could be something
as early as a pdp 11/20, 11/05, 11/34, 11/35, or as late as a 11/24
or 11/44 -- possibly others.

Not easy or cheap. It's bulky, heavy and would usually require 2
persons to move around. I've moved various of my pdp11s around and
it's always been hard work. Stashing a case of beer in the bottom of
an H960 is good incentive for assistants.

Hi All,
That's a BA23 in tower stand, aka a room heater.
The system looks like a Micro-PDP11/23 or /53.
The tape unit seems to be an old model TK50 (it
has no markings, which was standard for the old
units), the disk could be an RD-53, it has the
same alu frame. Other disks (RD54) are full-metal,
or smaller (RD31, 32, 20).
The buttons on the front panel seem to be just 4,
not 6. The original Micro-11 (aka 11/23) had 4,
because it could handle only a single disk (the
10MB disk RD50); the newer systems had two extra
buttons (online and WP) for a second disk.
So... looks like a Micro-11[/23] with larger than
standard disk (RD53)and the original TK50 tape.
On the back panel we only see the bulkhead for the
system-standard DZV-11 4-port async module, of
which ports 0 and 1 (console and aux, resp) are
in semi-fixed mode.
Cheers,
Fred
PS: for people in NL; I have a few 11/53 systems
left... :)

Those CD Doctor "cleaners" (they actually do a minor
resurfacing of the disc) have rescued several discs
for me.
Hi,
I have the same problem with an old floppy disk (2,5). Any Ideas what I
can do?
Thanks a lot and kid regards,
