Does anyone have an image of the Fortran DECtape which is compatible
with RT-11 v2C?
I have a copy which is labeled as being suitable for RT-11 v2C, but it
does not have the 'fortra.sav' file.
There is a 'forgen.com' file. Since RT-11 v2C doesn't support command
files, I don't think the tape is
for RT-11 v2C.
Thanks!

A coworker of mine showed me this link. Whatever it is looks pretty sweet,
but I don't think I've ever seen a similar machine. Anyone know what it
is? Is it even a computer, or some sort of teletype switching office?

Hi,
I run the website http://oldcomputers.net
I get a lot of old computer systems offered to me for cheap or free, but most I don't want - too big, or too far away to pay shipping.
A while back I asked for other collectors who would be receptive to these orphaned systems, and over 60 people have signed-up so far!
But entire parts of the US are still open - the East coast is covered pretty well, but west of the Mississippi River these is almost no one until the coast. I've got Nathan in Iowa, Richard in SLC, but that's about it.
Send me your name, email, and what you collect, and I'll try to get you some good stuff (some people got some REALLY good stuff).
Thanks-

Some ccmp listers will have fond memories of MPW. I know I do. Still
runnable on my PPC G4! (OS X 10.4) & I still occasionally need to build
with it.

Today, September 4th, in 1986, we completed MPW 1.0, 25 years ago!
I just thought we should note the occasion.

Just a reminder - this Saturday, just a few days away, RCS will be
doing triage on our big pile of VT100s and VT100oids. We need the
space! Incoming Cray!
Failed VTs will be available for pickup at our open house in
Providence, RI (see rcsri.org for directions). I may be able to move a
few to the MIT Flea on Sunday.
And of course, cash donations are very much appreciated, but not
required. But appreciated. Really appreciated...

Finally pulled out the TRS-80 Model II tonight with the intention of
actually working on it for once (shocker!) and trying to get it operational.
It powers up, drive spins, screen comes on, lights glow, etc. Insert
any one of about 20 8" floppies that I have that are specifically for
the Model Ii and.....
Nothing. Well. BOOT ERROR RS, which is translated as, "Disk not in
RadioShack format."
I'd believe it for one or two, but all of them? It seems unlikely,
although I could blame bit-rot perhaps. I'm hoping it has something to
do with the hardware instead.
Popping it open, the unit powers on and the drive head is dropped to the
spinning disk, then lifted, then dropped, then lifted, and the error
occurs. I cannot see if the head is close enough to the disk or not
(and I have *no* idea of the tolerances anyway) and am not sure how I'd
adjust it -- or drive speed, etc. if that's an issue.
So, anyone got ideas? There *is* a remote possibility that all the
disks I got were wiped either by the previous owner or in some sort of
magnetic disaster, but they're well-labeled and came from a working
haul, so I have to imagine that they're still good. Or at least, I'm
hoping they are. (The bits are damned near visible on these things,
after all.)
Your ideas and good guesses welcome and very much appreciated.
Nathan

I need to get rid of this drive. I don't have the TI990 computer for it anymore.
If I don't get any offers in the next couple of days I'm going to scrap it out (that said - this is not free).
It's a TI CD 1400 branded drive. Magnetic Peripherals 944B drive.
The unit weighs 175 pounds so it puts out of the standard shipping range.
Please send any offers off list. Drive is located in Port Huron, Michigan.

Precisely, yes. But even with byte encoding of bitstreams you have an
endian problem. At some point the capture system imposes its personality
on the process and you simply have document what you've done so the
upstream ('viewer'/'accessor') toolset can take it into account in post
processing. The adding of metadata context is what contributes to the
deterministic outcome, rather than attempting to force raw capture into a
rigid format.

Thanks for the reference. I must have come across it before at some point
as it seems very familiar. But it wasn't a work I was referencing yet in
preparation. I'm studying it closely, along with things like the UPF.
What strikes me is how there are several originating documents around
effort followed by long silences and lack of back references. It may be
down to the relatively cursory nature of my work so far, but it seems
adoption of these formats and processes has been either quiet or limited.
Is that a misapprehension on my part? Any other efforts you think I should
investigate?

My HP Laserjet 4050 works fine with a USB to Parallel cable.

I received an old HP LaserJet 6P. According to the doc it has an IEEE-1284
interface (B and C ports). The PCs I have don't have parallel ports. Will a
USB to parallel converter cable "just work" or how should I hook this up to
a Windows XP box? Also, any comments on this unit? I remember seeing
some threads with people praising/damnning various HP models. Thanks.
