RT-11 has always been 6.3, RSX-11 is 9.3 IIRC, and UNIX doesn't have any
fixed format - though early versions had a fairly small limit on name
length (12 chars?). All versions of UNIX allow as many dots as you can fit
in the length.

Hi. Just heard about this, so I dunno really what I'm talking about...
Appearantly, this company is (was) selling liscences for DOS 3.3. I'm
guessing that this is from a deal with MS. Has anyone ever seen this? Is
it available with another product, such as early Windows releases?
Ciao,
Tim D. Hotze
OK, to aviod confusion the first system in question is a SMS-1000, with a
PDP-11/73 board, 2MW RAM, RL02 Controller (DL), TK50 Controller (MU), Dilog
DQ606 Floppy Controller (DY). The SMS-1000 has an internal Floppy and HD,
which it thinks are a RD51 (DU) and RX50 (DU). The boot ROMs support DU
(DSA, the HD and Floppy), MU (TK50), and MS (TS).
I'm able to boot off of RL02 by entering in the bootstrap from ODT.
I've got RSX-11M and XXDP RL02 packs, and can boot from either. I've
managed to make a bootable XXDP floppy diskette. I can boot the machine
directly off of the XXDP floppy on power up. I can boot the XXDP floppy
>from the XXDP RL02 pack, and then boot the XXDP RL02 pack from floppy.
However, if I power up and boot from floppy, I can not boot the XXDP RL02
pack. Is this because the Boot ROMs don't support RL02's?
Does anyone have any instructions for a Dilog DQ606 controller? I gather
that it can be configured to act as several different floppy drives. The
drives that came with it are labeled as being a RX-50 and a RX-33, yet
RSX-11M sees both as RX-02's. I'd like to get these changed back to RX-50
and RX-33.
What does the device name 'MS', device type 'TS' stand for? My guess is a
9-Track tape drive.
I've also got a PDP-11/44 that I'm slowly working on restoring. It's in
two racks, one has a pair of RL02's which have been cleaned up. The other
has the CPU, 2 RX-02's, 2 TU-58's, and a battery backup. In looking at the
CPU, it looks as if it has a LED for the battery backup. Does that battery
need to be in the system? I would just as soon remove them and not have
anything to do with them since they are old lead-acid batteries, and I'm
not very fond of such things (spent 3 1/2 years of my time in the Navy
working on UPS's). Is there any reason that I can't just plug the whole
thing into a power source outside of the rack. I'm asking since for all I
know the battery and powersuppy in the bottom of the rack are some kind of
power conditioning circuit.
Also does anyone have any recommendations on how to go about testing out
the power supplies on the 11/44? I'd just as soon not blow anything up. I
have powered up the RL02's, but that is all so far. I'm waiting to test
the power supplies before I get the remaining boards that I need for the
system.
Thanks,
Zane

I'm trying my darndest not to get too involved in this thread, even though
I started it, but I need to set the record straight: The URLs I sent
weren't from ebay, they were from Haggle Online. An online auction that is
totally free to buyers and sellers, unlike ebay, that charges a fee to
sellers. Not that it really matters, since online auctions seem to be the
new "great satan" on this list. I would like to point out though that if
you don't know the true value of an item, why not let the public decide?
What's wrong with making a little bit of money off a hobby? I know this
probably isn't over, but I'll try to stay out of it, regardless.

The smallest I've seen run on 8080 and fits in some 100 or so bytes. It
was published in Kilobaud April 1978 page 102 and yes it was real.
To multitask on most anything all you need is an interrupt and save the
context of the current task and start some new task... the order, where
the tasks are and memory allocation can be somewhat tricky but, for
small tasks its pretty trivial. I've done it in 8048 MCUs where the
resources were 64byts of ram and 1k of rom and the tasks were keyscan,
display, serial IO and code conversion. The timer provided the
interrupt.

Do you mean the NCR Tower series? Or was this some other offering by
AT&T? I seem to remember that the old Tower 400's had 68010's - I've
still got a few boards somewhere for one (system board was about 1 metre
long and half a metre high!). I've got a complete Tower 700 with a 68030
as main CPU, and performance still rates really highly even these
days...)

> How do UNIX files work? Is there a header of some sort?
Not really. Certainly not consistently across all file types. Often
command scripts have a comment at the top, and some versions of unix (eg,
Irix) embed a "tag" number into executables so they can distinguish
individual programs/versions quickly, but other than that, filetype
determination is done by looking at various parts of a file and comparing
what's found ("magic numbers") to a database (the "magic" file).
So, for example, my system "knows" a certain file is a command script
because the first 256 characters are all ASCII (which means it's probably a
text file of some sort) and the file permissions are set such that it's
executable (not merely readable).
It also knows that a certain file is an ELF-format executable for a 32-bit
little-endian MIPS processor with a version 1 architecture (ie it will run
on *old* MIPS cpus as well as newer ones) because the bytes at offset 1 are
"ELF", at offset 4 there's a binary "1" (which in this context means 32-bit
not 64-bit), at offset 5 there's another "1" (little-endian), at offset 16
"2" means "executable", and at offset 18 "0" means "MIPS" (not Sparc,
80x86, 68000, etc).
Some magic numbers are much simpler to decode, of course: a file that
begins with "GIF89a" is a GIF file, surprise, surprise. And the more you
dig, the more detail you can work out.

True! I have the advantage that I see designs and immediatly see the
core of the design with all the fluff removed. But it's years of
experience and a good basic grounding in circuit theory that allows me to
look st stuff I've never seen and synthsize the elements of the design in

Troubleshooting is a very complex process that I've never been able to

is something that I find natural and easy. I carry that to design as
just a different problem to solve (cheaper, faster, better; pick any two).

Exactly, hence the value of an auction environment. That is what "whatever

We've been over the "is it OK to sell stuff here" question a million
times. The auction thing adds a nice twist because they address the
all-important valuation issue.
Anyway, did you have anything to do with the Microsoft Museum

Interestingly enough there was a thread recently on comp.sys.ibm.ps2 re the
collectiveity of PS2 s. Most mentioned the 700. Some quotes :
"The Thinkpad 710T (IBMs first Trackpad). I have one - without the 5MB
TP-File. There were two different model-lines out: one has a 2.5" IDE HD,
the other has a 5,10 or 20MB PCMCIA Solid State disk. The SSD-models have a
different planar and cannot be converted into IDE-models. I have a
SSD-model (2523-AY9) but no TP-Filecard. Too bad."

That's probably it. Though not the first with a built-in pointer. As Doug
mentioned, GRiD had one, as did the Mac Portable (1989) and the Atari STacy
(year?). Not sure what year the Outbound came out but I'm pretty sure it
was pre-thinkpad (maybe '89ish?).

Looks like I made a real splash with my first post since resubscribing! In
my defense, all I have to say is this: If don't really know the current
street value for an item and I want to get rid of it, the best thing to do
IS put it on auction and post to similar lists and newsgroups. I'm sorry if
I offended anyone. During my hiatus, I was spending alot of time on usenet,
a place where this is done all the time. Guess I got a little brainwashed.
If it's gonna cause a problem, I won't let it happen again.

After reading Doug's message, I checked at my favorite trift store and
found a pile of manuals for a Wang PC. NOT Personal Computer but
Professional computer! The manuals seem to be sort of generic to all Wang
PCs. None of the manuals mentioned a model number of the computers
themselves but they did list the model numbers of the various options and
accessories.
I also found three Wang computers. They were under a pile of stuff so I
didn't get a good luck at them and I don't know if they were Wang PCs or a
different model but they looked like the PCs. Two looked like 8 slot
electronics units (that's what Wang calls them) and the other looked like a
5 slot unit.
