Cool! It's an 820-II.

More cool -- I'll check the diskettes that came with it to see if this

Sure, but I'm reluctant to make any internal changes w/o docs.
As always, thanks, Don!

Unfortunately I (somehow) missed the start of this thread, but I figured I
might as well jump in.
I don't even know for sure who asked the original question, but I hope
this gets to whoever is interested.
First of all, you need to set kermit to transfer binary files in order to
transfer tasks (I figure it handles this if you allow it to
automatically decide the mode as well).
Second, kermit-11 can send attribute packets, which tranfers RMS
information, along with the file.
Third, KERMIT-11 is somewhat buggy. I wrote a patch or two to remedy the
most obvious errors (which crashed KERMIT-11 if attribute packets were
sent).
However, I got tired of this whole thing, and wrote a program similar to
uuencode/uudecode for RSX, which preserves everything, while converting
to/from plain text files. I called it COD, and it's in MACRO-11. Not in
all respects a beautiful program (the source, that is), but it works very
nice, and it's free.
Using this, you just throw your file at COD, transfer the text
file, run it through COD, and you have your file back. It retains all
attributes, contigous state, and some other meta information as well (such
as file protection).
If anyone need it, it is free, available in source at
ftp://ftp.update.uu.se/pub/pdp11/rsx/tools/cod/

yes, seriously, my eyesight is not much good for soldering, or chip reading.
Everyone - Please remember this is not the altair you think of with the blinky
lights and switches, it does have a video out (some sort of terminal board)
and floppy drives. It has been sitting in a garage for some time, and it's
only an offer so far, not delivered.

Dear Vintage Computer Festival fan:
It is with great pleasure that I announce that the fifth annual
Vintage Computer Festival is being sponsored by the Computer History
Museum.
In conjunction with the CHM's sponsorship, VCF 5.0 will now be held at
the Moffett Training & Conference Center at Moffet Federal Airfield in
Mountain View, California. The dates of the event will remain October
26th and 27th. Moffett Federal Airfield is of course also the home of
the Computer History Museum. This year's tours of the CHM's Visible
Storage exhibits will be more tightly integrated with the VCF. The
collaboration between the VCF and CHM will make for an exciting
computer history experience.
Admission to the event will be $10 per person per day for full access
to Speakers, the Exhibition and the Marketplace, or $4 per person per
day for Exhibition and Marketplace access only. As always, kids 17
and under will be admitted free, and parking is free.
Important note for foreign nationals (i.e. non-U.S. citizens): because
the Moffett Federal Airfield is a United States military installation,
foreign nationals must undergo screening prior to being allowed on the
base. We regret this inconvenience. If you are a foreign national
(not a United States citizen) planning to attend VCF, please fill out
the Foreign National Registration form on the VCF website:
http://www.vintage.org/2002/main/foreign.php
Your registration must be received by September 26, 2002.
If you are a United States citizen, you do not need to register.
Stay tuned for forthcoming announcements regarding VCF 5.0 or visit
the VCF 5.0 website for more information:
http://www.vintage.org/2002/main/
Vendor booths are still available!
Best regards,

I was scrounging around last week and found a pair of HH 5 1/4" floppy drives that are marked "2.4" next to a disk symbol on the front. Just out of curiousity I picked them up and checked <http://marina.mfarris.com/floppy/Hitachi.html> and sure enough they're 2.4Mb floppy drives! I've never heard of these before. Does anyone know what the disk format is or where these are used? The drives are Hitachi model FD532EIU. The label on them says that they're made for IBM. They're in some sort of a plastic sled.

There's a AT&T/Pixel Machines model 964d 'video thing' down at university
salvage, and I was wondering if anyone had any information on them. It
appears to have been produced in 1989 by an offshoot of AT&T called "Pixel
Machines". Using google, the only result I can get that matches "Pixel
Machines" and 964 or 964d is a thesis of some sort, which doesn't have a
whole lot of useful information on the beast. As far as I can tell, it's
some sort of redering/raytracing 'thing', and from its outputs, it appears
like it might output NTSC video.
I'm not sure yet if I want to bother lugging it up here - it's about
2ft x 2ft x 1ft in size, and looks like it might weigh as much as a small
car.
Thanks for any information you guys can turn up,
-- Pat
does anyone know anything about these? does anyone have docs? i'd love to get
mine setup and working, but i can't seem to figure out details. like for
instance, there is a db25 on the back, and the robot doesn't show up as a scsi
id, are the robots on these things serial controlled?
docs would be best.
thanks all!!!

Your wife is probably correct. Consider your self lucky, my wife is
understanding. As a result, I'm the one that thinks I've got too many old
computers.
I've said it before, and I'll say it again, collecting old computers is a
disease! DECitis is one of the more extreme and dangerous varients of this
disease. Developing DECitis can be especially dangerous if you already
suffer from Bibliomania.
If you think I'm joking, think again.

PS at least the disease isn't as distructive as some.

I assume that you mean 2.4M. I did some searching on the 3174 and option 1048 for them is a 2.4Mb drive so that looks like that's where they came from.
Later I checked the drives closer and I found a disk in the one that I hadn't looked at. It looks like a standard 5 1/4" floppy disk. It had a plain white label on it with no brand name. The lable says "DISKETTE TYPE 2.4MB 3174 CONTROL", "LICENSED INTERNAL CODE - PROPERTY OF IBM", "MACHINE 3174 P/N 25F8499 E/C A78831 ML90095 MICROCODE LVL B2.0" etc etc so it appears that it's definitely for a 3174.
