Just got an HP 5381A frequency counter, and although it's basically
straightforward and simple, I was curious if anyone had a manual that they
could copy, scan, etc so I had it for future reference, or knew of somewhere
on the web that it might be stored in scanned or PDF format.

I went that same route. When I started collecting I went for diversity,
but I found I never have enough time, so now I concentrate on a small
range of systems I'm interested in, and even now I still wish I had
more time to play with what i've got.

NeXT shipped *A LOT* of machines, man. Now, granted, nearly none of
them went into households, but they installed (by practically giving
them away) huge numbers of them in american colleges, and a large
nameless US Gov't agency bought a VERY LARGE number of them.
I'm definitely not trying to be a NeXT-tribesman here...but NeXT's
products, and their relative success & failure, are some of the most
misunderstood things in the workstation industry.

AmigaDOS is different, but I don't know if it has all the features

Please.
Try running the A/UX CMW version. Validated B1(+) level system. Also had a
secure X Window system (no cut-and-paste between windows with different
security labels, etc.). My first "real" job was with SecureWare, the
company that wrote it (and similar systems for HP, DEC, Tektronix, etc.).
And, yes, we wrote the C2 subsystem for SCO Unix.
People who want to run C2 & B-level systems almost never know what they are
getting into.

Hello, all:
For those interested, I seem to have found at home another copy of the
history of the Apollo guidance computer book by Eldon Hall, speaker at VCFE.
I purchased a signed copy from him today because I thought that I didn't
have a copy at home. Surprise!
So if anyone is interested in the *unsigned* copy, I'll let it go for $35
including shipping. I paid $45 for the signed copy and bought my first copy
on Amazon for about $55.
Again, interested parties please contact me off-list. Thanks.

Though the original message was intended to be humorous, I have to
agree with you here. Though I've lived in the Washington DC area now
for about nine years, I've lived in Tampa for a while, and I have a
house (a rental property) in Treasure Island...Every day of the
Washington DC summer that I sweat and choke through leaves me longing

near this cold in the winter, and a certain lack of bullets flying

I recently found a PDP-11/23 (Model 11C23-FE) at Goodwill. It is in a tall
slim tower style enclosure, has a dual 5.25" floppy disk drive, a hard disk,
and 1024KB. It passes the memory test, and trys to boot from "DU0". The
light on the hard disk comes on for a few seconds, and then I get the
message

First is there a hard disk drive there????
If there is start with Tony's suggestion of checking the enable and
ready.
IF not, you'll need a drive maybe.
Do either of the floppies or their lights become active????
If they are it's looking for bootable media and there is none.
The other possibility is the drive(s) is/are disconnected or maybe plain
DOA.

Does anyone know where an online copy of the cipher f880 docs might be

I've got 5 Fuji 8" SMD drives (M233x and similar) just
inside the DC beltway (I-495) available immediately. You
pick up only; I will not ship these (weight with power supplies
is 35-45 lbs each). They all worked about three years ago, the
last time I fired them up. Anyone hauling them away also gets
my collection of Emulex SMD controllers and Fuji SMD manuals, and
the rack mount slides/trays, and whatever else I feel like making
you take.
Also available are some 8" Pertec voice-coil floppy drives, in
"parts only" condition. Manuals and some Pertec-specific
test equipment are available too. Again, you-haul.
Email if interested; first-come, first-served.

I've got the following PDP-11 equipment free for pickup in
Austin, Texas. David Williams from Houston has first shot
since he is coming to pick up some uVAX-IIs, but anything else
left is fair game. If you come get something (email me first!),
you have to promise that it wont be scrapped or the front panels
sold on eBay for some rich CEO's wall collection. I'd like it to
all go to good homes where it will be appreciated. (god, I sound
like an animal shelter)
- PDP-11/60 and UNIBUS expansion cage (and some maintenance printsets)
- two RX01's
- one RK05J
If anyone is interested, please email me. This stuff CAN NOT and WILL

I've seen this happen a couple of times. Someone that really wants
something will put a very high bid in, knowing that no matter what
happens the eBay bidding mechanism will automatically up their bid.
Someone else that really wants the same thing will then come along
and put in a very high bid. This causes the bid to automatically
shoot up to the lowest of the high bids.
Fortunately I don't bid this way. I only bid what I'm willing
to pay and that's it.

Another suggestion would be Brooklyn Bridge. You can transfer files using

While at the junkyard yesterday, someone had dumped a bloody lot of QIC tapes.
The original labels said "AS/400 SYSTEM SOFTWARE" and such things. Great,
right?
But then there were additional labels saying such things as "H:\ NT BACKUP".
Arrrrgh! They're reusing OS/400 tapes for such things? Bastards!

The only stuff I run that way would be PCs... for the Prime, I made

I recently got an old AlphaServer 4/275, and it worked for a while, and
then after I moved into another room, and it stopped working. I only have
one or two grounded outlets in my apartment, so I had to hook it to a
non-grounded one (via a surge protector, plugged in with a grounding
adaptor). I'm not sure if it's coincidence, but that appeared to kill the
AlphaServer (the power supply, to be precise). Is it technically possible
for non-grounded power to be able to kill a system? In general, what
type of hardware will require real grounded power to function? I have a
whole slew of PC's, for example, using non-grounded power outlets without
a hitch, so is this only going to be a problem for industrial equipment,
like AlphaServers?
Also does anyone know where I could get an AlphaServer 4/275 power supply
for cheap?

Not really. Logically, the innards of the hub are the bus. The ports are
the taps. Then, since the stations connected are typically some distance
away, you use an appropriate technology to get the cable to them, and
that's why there are additional transceivers (one on the host card, one on
the hub port) to drive the signal over a resonable distance. It certainly
changes the physical layout of course (short bus long drops instead of a
long bus with short drops).
> Now 10/100 switches really screw with it.
Those switches are just bridges, which have been around for decades (albeit
with fewer ports).

Er, yes, that was a typo, induced by trying to type 15 minutes of email in
a 5-minute slot :-)
In fact, part of the reason the Torch board causes Beebs to misbehave if
Torch's own code doesn't grab it and hide it, is that the 6522 is seen by
Acorn's Tube code (in the DNFS ROM) and Acorn's code will try to initialise
it (and gets it wrong, of course).

I used to run A/UX on a II (later IIfx) and I liked it. I
didn't find it all that much slower than running the MacOS
straight. I can even remember playing Hellcats (I think
that was the name; it was a WWII flight simulator) under

You want to inquire about software too. The hardware is mostly

I must say I was a bit surprised at how well done the show was. It wasn't
over-sensationalized at all. On the contrary, I thought it was very well
researched and did a good job of telling the stories and explaining the
technical stuff.
I was glad that they had more quotes from Jonathan Littman than from John
Markoff. Littman told Mitnick's story closer to what really was going on,
while Markoff stuck to his agenda of vilifying Mitnick, which he's spent
the better part of the last five years of his career doing. Markoff is
the kind of reporter I despise; one who attempts to make the news or mold
it in his view rather than simply report it.
But I don't think Mitnick's story is as rosy as he paints it either, and I
think he's spinning some revisionism on it. He's certainly got some
skeletons in his past that he's not owning up to.
Anyhoo, Draper's story is pretty much how I've heard it told before. He
really was just an unfortunate fall guy of sorts.
The warehouse where they filmed Draper is where my computers used to be
stored (well, a few still are, I'm not quite done moving yet :) There
were some shots of me typing on an Apple ][ (you may have noticed the
"CALL -151" on the screen at one point :) but you couldn't tell who it
was, just hands. The display of 1's and 0's that showed periodically was
generated on an Apple ][ as well (that is, by far, the acme of my career).
There was also some other stuff, like 6502 assembler scrolling by, and of
course the computers they showed rotating were all mine ;)
Well, that was fun. One to the next show: I'm providing some Altair
footage for a National Geographic special on computer history.
I'm also in the process of developing a documentary on the F14 flight
control computer, but that's a slow-going affair. Once the VCF's are over
for the year then I hope to kick that up into full gear.

Easy to setup; in your case I'd format a disk in the old PC (360K),
take it to a newer PC, SYS it with 6.22, put the files on it
for the ZIP drive, and boot it on the old PC. The parallel ZIP
only needs a 1/2 dozen or so control files to work.

He's not mistaken, while the latest version(s) don't look to still support
68k processors, it does support a LOT of different CPU's.

I've no idea, but I think people have done this successfully. I've only got
one VAXstation 2000, and it's got bad RAM, so the only thing it's good for
is a disk formatter (but then that was all I wanted it for in the first
place).

Anybody know what these might be out of?
No company name/markings that I can find.
About the size of a modern PC motherboard, maybe a little
smaller. They DONT look like DEC boards to me, but I may
be wrong. The "levers" on each board to remove them are
two different colors - one white with a label, one colored
(I guess to color-code installing the boards). Each board
has two card-edge connectors to plug into a backplane, and
some have top-edge connectors (cables, etc, I would guess).
Here's what they are so far:

Yup. Time to install that lime pit....

Well... If it were me, I'd just hook the things together modem to modem (or
serial port to serial port as the case may be) and send everything over
using terminal software. Procomm was what I used on my olde '286 and XT;
Hyperterminal for my Pentium machine.

You would mention that... I've got a Dell PowerEdge 2400 sitting three
feet away that's slowly robbing me of my hearing... it has a "slow mode"
but since airflow around the unit is a problem, I don't feel safe using
it... so it stays set on "hurricane"...

I'm not sure what would qualify as "real" to you... would it
have to be a machine built from the original schematic prints?
Or would a re-implementation using modern devices (e.g. FPGA)
qualify as "real"...?

I've not looked at one for a while, but that makes more sense. Presumably
the 6522 is mapped into the Beeb's 1MHz bus space.

Oh, then I stand corrected. The Tube is the only 40-pin connector on a
Beeb.

Anyway, I noticed that one of the big electronic surplus places had tons of TOPS network stuff ~5 years ago.
I think it was Alltronics in San Jose, but I am not sure.

Subject: Vintage equipt
Dear John, I am trying to find vintage mac networking equipment,
specifically TOPS Flashbox and TOPS Flashcard. They were used for
interconnecting Macs and PCs around 1991.
Any suggestions would be appreciated.

I picked up an IBM keyboard at the Village des valeurs on saturday. It
has nice tactile feedback, no vanity keys and takes up less desk space then
my aged Keytronics. Cool.
However, it "doesn't work". When I plug it in and start the computer, all
3 leds go on, then NumLock goes off and nothing responds as I would expect
(caps, scroll, del to get into bios, ctrl-a for adaptec scsi monitor)
I was under the impression that there were 2 types of keyboards for
clones: PC/XT and AT keyboards. This keyboard has a PS/2 style miniDIN-6
connector (though I now notice it doesn't have the rectangular plug in
the middlish that my other keyboards do), so I assumed it would be AT and
therefore compatible with modern motherboards. No luck :(
Looking on the bottom I see :
Part No : 1395300 IBM
ID No : 2117313
Date : 12-05-1992 (C) IBM Corp. 1984
Plt. No. : WP1 Model : M2
Made in USA
[bar code]
1395300112117313
So, do I have a defective keyboard? Or is this not even a PC keyboard but
for some other piece of equipement?
