After being contacted by Don's niece, I went down on behalf of CHM in July and
retrieved
every box of media that was in the storage unit from his garage. I've spent several
months
going through everything, including the PCs that were there, and could not find what I
had
assumed were disk images that are described in the 'sysdisk.txt' file that Don
maintained
which I've attached.
Does anyone have any contacts with the San Diego folks that knew Don that could help with
figuring out where these images would have been? It's possible either they were on
more
modern PCs, or on a CP/M system. CHM is not willing to take everything that is still in
the storage unit (mostly paper and the computers that were in the garage). I'm going
to
have to make a pretty strong case for trying to recover any of the systems that are still
there.

That's really bad news. If they were images it seems like you would have
found a setup that he used for copying them out again. It is suspicious
the names of all the disks are limited to eight characters. That would
sort of indicate they were files on something.

Exactly. I would assume it started on an MSDOS machine since I had heard he
was using Teledisk. I also suspect some just came to him that way, since I've
been able to find what I think may be the original disks, but it isn't everything
that was there. I've tried reading some of them and it's a very mixed bag. They
were stored in a garage and I've run into some that got wet. I also found most of
the hundreds of disks from G. Herr that I sent him a LONG time ago. I have been
able to recover a few things that people have been looking for, like TurboDOS 1.43

If you ever run into the Monroe ones let me know. I spent years looking
in vain for them and always Don's SYSDISK.TXT kept coming up in searches
taunting me. I don't even have the machine anymore but, I spent so many
years looking I can't give up now. I won't let it beat me. I'm just
going hang the floppy on the wall as a trophy.

Well, I don't think Don was even much of a Windows person. Most likely
his stuff would be stored on a DOS drive of some sort. Have you looked
for tapes or optical media that might have been used for backup?

Yes. There were no obviously labeled backups. There are copies of DOS tape backup
programs, though :-(
No CD-Rs, or machines with CD-R or tape drives. There were one or two CD-Rs that appear to
have been
sent to him with CP/M content. It's pretty frustrating to have gotten this far and not
actually have
found the files or any backups which is why I'm hoping they may still be on machines
that weren't in

Then he would carefully take it over to his own computer, of the same

cp/m boxes. Pretty silly I guess.
It's nice we are still talking about Don today. What made him a good guy
was not his collection but, that he shared it with anyone who asked.

I visualize at least four file cabinet drawers full of floppy disks.
Even if he DID image everything, he would not have discarded the floppy
originals. If you haven't seen a cubic yard of mutually unique floppies,
then his collection is still missing.

I retrieved a Ford Explorer's worth of media. Well over 1000 floppies.
What I did was went through as much as I could do before literally
getting heat exhaustion in a totally packed 10x10 storage unit,
pulling out any box that looked like it contained media.
The recovery rate has been OK so far, but there's no way I have time
to do it all. Much of it is unlabeled, or are applications (lots, and
lots of copies of DBASE, Wordstar, etc. etc.).
From looking at the pictures, it was just whatever was in the garage.
The disks from me were still in the boxes that they went down there in.
They certainly weren't in filing cabinets..
I can sort of figure out what was done later. He had dot-matrix printed
labels on those (some of which you can see in the label jpgs I've been
putting with the .img files on bitsavers)
so I've been trying to match those up with the contents of the .txt file
What I've done sort of matches.
Someone else from CHM is going to be down there on other business for
the next couple of weeks, so this is probably the last gasp of our involvement
with any recovery.

You have a herculean task! Unfortunately, the Alpheus and Peneus rivers
won't help any.
Don't overdo it! We can't afford to lose you, too!
Actually, the picture of his garage didn't look like I expected it to be.
I expected a full cram, with no way for "outsiders" to differentiate
between the clutter and the goodies.
For XenoSoft, the most important Intellectual Property is the collection
of sample disks. Everything else could be re-written, and you never know
when you might need to go back to the original to recheck something - "Ah
HA! That disk is 77 track, but it is FORMATTED to 80 tracks! THAT's why
disks more than half full have file position errors on some files!".
Don apparently always worked alone - even his wife didn't know about his
hobby. Therefore, his labelling, for his own use, might be completely
indecipherable for anybody else. 17/4 could mean, "disk is the 4th disk
in the 17th box", etc. Although he probably had extensive imaging to make
it easier to fulfill requests, his primary collection is disks, not
images. His memory was probably eidetic, and he probably relied more on
remembering everything than on organization and labelling.
A VERY large portion of the sample disks will be duplicates of the user's
WORDSTAR disk, no matter what was ASKED for. And the USER labelling was
oft less than useless. Lots of the "Televideo" disks that came in were
due to the user not understanding that the name of the TERMINAL was not
the name of the computer system.
Even if the numbered or labelled sample disks that comprise the REAL
collection are never found, there is a wealth of information scattered
through what is there. Finding the image files would permit resuming
SOME of the day-to-day ways that Don helped people.

Uhh...I used a Hazeltine 1400 for a long time. (then a 1420, then a
1500) I don't recall anything even remotely ANSI-like about its command

H1400 was ANSI just like VT100 (in Vt100 mode) and
many others. The
escape sequences were ANSI plus private (hazelitne additions).

More likely the 1500, which definitely did use a ~ leadin for what for
most terminals would be escape sequences. (The 1420 used an escape
leadin but was otherwise completely unlike X3.64 or X3.41.) The 1510
and 1520 were switchable. The 1552, well, in the words of termcap:
# Note: the h1552 appears to be the first Hazeltine terminal which
# is not braindamaged. It has tildes and backprimes and everything!
(The 1500, in addition to using ~ as a leadin, displayed ` as a solid
quad rather than a backprime. I forget whether it filled up the whole
character cell; I think I still have a Hazeltine of some stripe, and if
so and if it still works, I can check what it does in these respects
within the next few days.)

After a little checking, it was the 1500--it was 1977 when I used one.
The attribute occupying a character space was indeed the godawful WY-50.

I received a few sample disks with the disk format identified as "Wyse",
so they must have sold a few. A significant portion had "Morrow" content

a rare

Remember that in the days of Teletype, ALTMODE was character code 175 or
176 (Umm, 7D or 7E for the octally challenged). Hazeltine was using the
ALTMODE character to introduce command codes, as intended. Only later
was ALTMODE redefined to be 033 (1B) = ESCAPE.

Sure, but this was a terminal that was brought out in 1977. X3.4-1968
has 7/14 as a tilde character.

It came to mind because of how easy it is to use it to switch between
various DOS and DOS-clone type operating systems. If that's the case, and
these files are small, they could easily be hiding in a disk image file on
a hard drive somewhere.

It would seem odd to store that stuff on a Win9x or Mac. A machine running
MacOS X could have been a possibility, but if he wasn't a *nix guy, then
that wouldn't seem likely either.

Gulp. I first read "Maxtor ESDI" and then "wiped"...that sinking

is awful. If this was the main disk image storage, let's hope someone just

Hmm, I think that's a worthwhile route to investigate - either get the
drive into a more modern system, or boot via floppy and either serial-link
data blocks across or run something to scan for anything that might be a
teledisk signature. None of which are trivial, of course...

That VT100 terminal box goes with a VS11/VSV11 raster graphics system for a
PDP-11.
In the VSV11 Interconnection Diagram on page 9 of this manual it is shown
as a VT100-LA or LB (I think the only difference there is 115/220):
http://www.bitsavers.org/pdf/dec/graphics/MP01102_VS11_Engineering_Drawings…
In the VS11-FX/HX/JX Raster Graphics System Installation Manual
EK-VSFHJ-IN-001 there are illustrations of this box being used in
combination with a VRV02-AA/AB color monitor where the box is refered to as
the "keyboard interface box" and the combination of the monitor and the
"keyboard interface box" makes up the VRV02-FA/FB.
The "keyboard interface box" video output feeds into the VS11 where the
terminal video output is then fed back out along with the VS11 raster
graphics output to the monitor.
I can't find an online copy of the EK-VSFHJ-IN-001 manual anywhere. I have
an original hard copy of the manual.

I have one of those VT100 boxes and the three board set, M7061 Sync
Generator, M7062 Memory, M7064 Display Processor. I need to get them
installed in a system and see if they work.

Do you have a VRV02 Monitor ? I looked
on google but, can't find a
picture of one. Be neat to see a video of it all up running if you get
it going.

I have no idea of what this might have been intended for, but it seems
obvious that it's simply a version of the VT100 that lacks a monitor.
Since the standard VT100 board has an NTSC video output on a BNC
connector, one could certainly use this with an external monitor.
Very interesting, and very odd!
