I don't really see how the fanout units on offer (or my unsuccessful
back-to-back device) could do that -- the termination isn't in the
transceiver or fanout unit, it's a resistor on the end of the cable.
Anyway, it would still only be one termination domain. Or maybe I've
misunderstood what you mean? If you mean my back-to-back transceiver idea,
yes, if it had worked, you could use it to split a termination domain into
two, just like a two-port repeater, or a very simple bridge (except a
bridge usually separates collision domains too).

Yes! I just repacked my lidless 4116 chips. I only ever got as far as
cementing slide-mount covers on one and sticking it in an Apple II at the
top of RAM and demonstrating the effect by clearing video RAM then lifting
the lid. Many bits sparkled in when light shone on the chip.
Now that I have a digital camera, I'll have to take pictures (as soon as I
buy/find/make a Mac crossover cable to connect a QuickTake 150 to my Mac).

I was a beta tester for the Spartan in 1985. Somewhere I've still got my
contract with them (all I could find on a casual search of my bookshelves
is a copy of the docs). I have the case for one in the basement; I forget
what happened to the mainboard. I think it died, or else I wouldn't have
stripped the supply for another project.
During my testing, I remember running Enchanter on the Apple CPU and Sorcerer
on the C-64 CPU, typing a command on one, switching to the other and typing
a command there to multi-task the games (since the disks were so slow).
Interesting concept, but about 50% the cost of a real Apple. If they ever
sold any, it would have been to some serious die-hards. Mostly back then,
Apple guys and Commodore guys didn't mix much. Kinda like Atari guys and
everybody else. :-)

uPD410 is 18-pin 0.3" width, 4k x 1, with one ~CE line (the MOS Technology
MCS6550 has 2 ~CS and 2 CS lines and it's 0.4" wide). I can't find any
data on a 4600 but I assume it's similar.
If you're asking about the 6550 I'm looking for, yes it is single 5V rail,
but it's 1k x 4 and it's not Motorola. In fact, I'm fairly sure no-one but
MOS Technology made them.

A friend of mine has a Televideo TS-802H that he is looking to part
with. I was familiar with the machine a few years back, and I'm sure
that it is still in good shape.
If you are interested, contact Dick Hubbard at 619-229-0955. He will be
pleased to hear from anyone who might like the machine.

I don't know how they got there, but I remember seeing a large pile of

there.

I've stuffed a few other things on my web site at

A few of the files are bootstraps taken from handbooks or manuals, but
several of them are little bits of nonsense I wrote when I first

laugh out loud :-) If you think the syntax is a little non-standard, it's
because I had to write my own cross-assembler and I hadn't used MACRO-11

>A Network Server 500 is one of Apple's two ill-fated Unix server models.
Not to mention thge _very_ ill-fated Apple Networ Server 300, which never
made it past the prototype stage. My web site, Applefritter, is hosted
on one of these machines.
"The ANS 300 had the same architecture as the 500 & 700, but was intended
to be an easily rack-mounted unit intended for Internet/FTP/Mail/Web
serving, departmental and small database servers, etc, and consequently
less expansion. It has two removable drive bays and one fixed drive
(behind the LCD). Much of the serviceability & security was abandoned for
the sake of size. For instance, there is no obvious way to secure the
drive bays, or the motherboard tray from being removed. The power supply
is fixed and would be slow to field repair. The fixed hard drive mounted
behind the LCD is very hard to reach, etc. The key lock on the front
controls only the "on, lock, service" options, unlike the multiple key
lock controlling those functions plus doors and security on the full size
500/700 units. These issues eventually ceased to be important, however,
as the ANS 300 never shipped.
"Code named Deep Dish, the ANS 300 is essentially an Apple Network Server
without the large drive array. As a consequence, the computer is only
four rack-units high. The logic board is in the bottom of the unit on a
slide-out tray. There are two standard ANS removable trays on the right
side of the unit's front. The Deep Dish also has one fixed internal
drive, and the floppy drive is fixed, as well. Apple also had plans to
produce an external drive array for the machine, reason for the ultrawide
SCSI port above the PCI slots."

At least to start with, I'd ignore the MSCP stuff and play with the 11/73
and RXV21. It's easier to see what's going on, since you can single-step
and look at the RXV21 registers; MSCP is a relatively complex protocol
which uses command buffers in memory, and the registers won't tell you
much.

An RXV21 (RX02) bootstrap is different from an RXV11 (RX01). Below is one
for an RXV21. I also have quite a few little routines to do things like
echo to the console, test/size RAM, dump memory, find CSRs, do serial port
loopback tests, etc; all small enough to enter using ODT. Mail me if you

I don't know either, but I might hazard a guess that they originated in the
days of thick ethernet, when taps were expensive, and had to be fitted at
specific intervals on the thick coax. Then perhaps it might make sense to
connect two devices to one tap/transceiver. I'm just guessing, though.
Now if they'd been the other "gender", so to speak -- ie, if they could be
used to connect one device to two transceivers -- it would be tantamount to
a bridge. Then I could probably use one as a media converter by adding
both a 10base2 and a 10baseT transceiver, and link the 10base2 part of my
home network to the 10baseT part without leaving a power-hungry repeater
running all the time. I don't think they'll do that though. I once tried
it with two transceivers back to back, and just got millions of collisions.

OOPS! I misread the previous post . . . it does say 1k x 4 bits.
The only 22-pin 4K-bit sram I remember from those days is one from EMM-SEMI,
but the number escapes me. Nevertheless, the only SRAM I remember in a
22-pin package other than the EMM-SEMI parts, was the 256x4 2101. There
were plenty of non-multiplexed DRAMs in that package, but few SRAMs.
If you have 22-pin parts and the memory diagnostic is failing on a 4K-byte
boundary, it's likely the parts are something wierd. The conclusion that
Philip has reached here is quite plausible. I'd explore his proposed
solution before going any further.
MOS Technology did build a few oddball parts, but I don't remember seeing
any of their parts as being THAT odd. My MOS data books don't include any
memory parts, though they did build some ROMs at that time.

Correct :-)

Yes, I'm sure that's true. The 2114 PETs are rarer, but I can't see any
reason to use 200ns devices, except that's what MOS Technology (who were
largely owned by Commodore) were making.

I've got the schematics for all 4 types. They're almost identical except
for slight differences in the memory decoding.

Oh, I did that to check that it was definitely the RAM and not anything
else, long before I posted my request. I could fix about anything else on
the PET, but I draw the line at grinding the top off to poke at individual
flip-flops in an IC :-) FWIW, the first job I had in
computers/IT/whateveryoucallit was looking after (and repairing at
component level) PETs and other micros, in 1981.
The PET determines the RAM size by reading and writing a byte in every
block and assumes it has found the top of RAM when it gets an error. It
was just coincidence that one of the 5th pair was the one to go. So I now
have a 7K PET, because I put the faulty IC in the top pair. It reports
6143 bytes free.

I would have thought a 2101 was far too small. These are 4kbit chips.
I agree 200ns probably isn't essential - my PET of that date uses 450ns 2114s.
On the 1MHz 6502 you have 500ns between the two clock edges that govern RAM
timing - one guaranteeing a valid address, the second latching in the data.
(FWIW there were FOUR motherboard designs for the early PETs, based on all
permutations of 2114 or 6550 RAM and 2316 or 6540 ROM. Mine is late for an old

That's right. When they revised the ROM code, they revised the motherboard so
that all ROMs were 2332s (and the sockets would take 2732s) and all RAM was
dynamic.
The thing that bothers me is that it says 3071 bytes free. This is EXACTLY the
number of bytes free you get on a 4K PET.
My advice - Identify the suspect pair of chips (remember these are 4-bit wide
parts) - I have the circuit diagrams if you want - and swap them with the
corresponding pair for the top 1k of RAM. You should then get the message "6143
BYTES FREE" when you power up. (Or try swapping them with the video RAM -
you'll soon see if the chip is dead!)
I suspect, however, you will still get 3071 BYTES FREE.
Let me explain. On these early PETS the top four address lines come from the
processor and go straight into a 74154 decoder, AND NOWHERE ELSE. This outputs
sixteen block select lines - one for each 4k of memory. Your PET is failing
memory test at exactly the point where it passes into the second 4k block from
the first.
In short, I think a failure at the block boundary is too much of a coincidence.
I'd trace out what this line is doing from the 74154 (there is only one, and
it's 24 pin, so you can't miss it!) to the RAM. Failing this, I'd suspect
something else in the chip select logic. (It could, of course be a failure that
affects a whole chip, but I'd try the other things after you've swapped RAM
chips if the BYTES FREE doesn't change)
As I said, I can lend you my copy of the circuit diagrams if you haven't already
got one.
Philip.

A good goal for you would be to get everything working under RT-11. That's
a great way to learn.
BTW, if you don't have a bootable 3rd party controller, or the DEC board
with the boot ROMs, I hope you've figured out how to send the bootstrap
over a serial line from a PC (I never did).
Zane
I did. I used to boot my 11/34 from RL02's with a 386 PC running Procomm. I believe I put the code in just a basic ASCII text file one line at a time with a carriage return after each and then uploaded the file as text over the same serial console line. Worked like a champ, and it sure saved the fingers from pressing those little chicklet keys on the programmers console...
This is probably OT, so flames to my address.
I finally tracked down a source of upgrades for my Apple Network Server 500.
It will shortly be upgraded to 80MB RAM, and I'm mulling over buying a new
processor card for it ($200! cough). MacWorks has some stuff in stock. So,
with this buff discontinued box, I'm thinking of getting it a DSL line to boot.
But I can't find a straight answer if all DSL services give you a static IP
address or not. Do they? And should most of them work with AIX 4.1.4? I would
think so, since it's just a DSL router and the ANS500 plugs into that like
any other network.
Thanks, sorry for the off-topic. (But hey, we've been discussing iOpeners

In keeping with nerd tradition I've got the thing all in pieces before even

But the 44-pin connector is right there as promised. I'm thinking of maybe

Hello again,
Well, due to the overwhelming response for these 2-port and 4-port Ehernet
fanouts (actually, none) I'm posting this one more time. Since each of these
weigh less than a pound packaged for shipping, your total cost for one to
three is only $4.80, delivered in the US I will send these internationally,
but the cost will be higher. The current list price on the two port units is
$80.00+, and the 4 port units go for $200.00+. If there is no interest by
tomorrow morning, I'll be listing them on eBay.
Perhaps someone can tell me, on list, why no one on this list has any
interest in these. Maybe everyone is saving their money for iOpeners d8^)

No. The earliest PETS almost all used the MCS6550 SRAMs I mentioned; a few
used 2114s (different and fairly rare PCB). The later ones all used 4116s.
None of them ever used 2101s or 2102s.
I'm looking for a MCS6550; nothing else will do :-)

I've got a GRIDcase 1530 here, with no power supply. I tried using one
of the cheap 9.95 "multi-voltage, multi-attachment" generic power supplies
I have here (use it to charge my mavica battery).
Power supply's max is 12V. The GRiD says 16V, but someone told me they'll
run off of 12V (automotive voltage) too.
When I plug it in and hit the switch, the status lights above the keyboard
flash on and off rapidly (continuously) in conjunction with a "ticking" noise.
My guess is, the power supply isnt up to snuff with what the laptop wants.
Anybody got a power supply (and/or an entire system WITH power supply) for
a 1530 for sale? In fact, I'd be interested in ANY GRiD hardware that
anybody on this list has for sale.

I'm not at all sure what you've said here, Allison. Aren't we in agreement?
The 2101 was a 1k-bit sram organized as 256x4 with separate inputs and
outputs.
The 2102 was a 1k-bit sram organized as 1kx1 with separate in and out.
The 2112 was a 1 k-bit sram organized as 256x4 with common ins and outs.
They're all different, but whoever wrote the message to which I attached
mine already knew that it was a 256x4 in a 22 pin package 0.400" wide.
Additionally, there was a 2115 which was a high-speed (25 ns) 1kx1 sram with
open drain outputs. I saw few applications for that one, however. It had a
cousin, the 2125, which had the same pinout and architecture, but had
tristate outputs.
Things got muddled when the iNTEL folks started using unused numbers in the
1K-bit family, e.g. 2114, for memories larger than 1k-bits. The 2114,
however, was just a microcomputer-compatible (slow) version of the already
widely used 2148/49, which was a fast (35-70ns) equivalent to the 2114.
They also made the 2147 which had the same bit count as the 2148/49 but with
a 4kx1 organization with separate input and output and pinout compatible
with the much slower TMS4044.
The PET 2001 was pretty early among the production microcomputers, hence may
have come along too early to capitalize on the high-volume production of the
4K-bit srams.

I'm not certain I know which of the items on my list you're referring to ,
but I've learned that I have only five drives to deal with, so I'm not
worrying about making a board at this juncture. I've got to adapt from two
fairly standard connectors, i.e. 40-pin IDE and +12, 2x GND, +5, of which
the +12 isn't needed, to that 44-pin connector on the notebook drives.
The best arrangement I've seen is is a dual-row by 22 with short soldertails
sticking strainght out from the connector in such a way as to facilitate
soldering to a 2-sided PCB. That, at this point would work for me. I have
an adapter between the two connector types but that's just a mite too large
for my application, particularly since it restricts my ability to mount the
drive such that it's centered on the PCB, half protruding through the top of
the board and half through the bottom so as to avoid interference with the
adjacent cards.
So, John, did you find they were back-ordered on the ribbon cable? Since
I'm in no hurry, perhaps it doesn't make much difference. You're right
about the suitability of 50-conductor ribbon, though.

I think the basic number you're looking for is "2101" from the same 1K
series as the famous "2102" which is a 16-pin 1kx1 with separate in and out.
The 2101's I have are not fast enough to meet the 200ns spec. However, not
much of anything that was readily available at the time the PET model 2001
came out was that fast. Either it was quite a bit faster, e.g. 2147, 2115,

Maybe somebody can clarify something for me. I had an 3100/M38
a few years ago and had to buy a disk for it. At the time I
bought a Quantum 210 MB drive. In order to use it with VMS
I had to get a special utility that I ran from my PC with the
drive and had to turn off the "Write-Preallocation" feature
off on the drive.
Is this strictly a VMS thing?
Is anyone interested in acquiring this rack mount communications
controller in new condition with manual and disks. A very casual
reading of the manual suggests that it is intended to provide
access to IBM and compatible machines including Systems 360/370/3
as well as 4300, 8100, system 36 and AS/400.
Communications protocols include Synchronous, SDLC, SNA, BISYNC,
X.25, and 3270 Emulation.
I would like to get at least $20 plus 1.2 x shipping for it, else
I will strip it and send the metal off for recycling. In any
event, it is gone by the end of March!

I am still trying to track down the Motorola structured assembler for

said "any operating system with FORTRAN").
Do any big iron folks have this?

Do any of you fellows know of a ready/reasonable source of the 44-conductor
connectors and cables used with notebook drives? I believe the spacing of
the connector pins is 2mm. I need a limited about of this stuff and a few
of the IDC connectors to be used at each end of the cable. The adapter I
have for this drive type has a typical HD power connector on it along with
an inline pc-mount connector that would also be of interest.
Any suggestions?

There's great hack running around where you take a regular 44-pin cable
that's long enough and attach a second connector immediately adjacent to
the connector on one end. You use the inner pins of the end connector
and the outer pins on the new connector to attach to the motherboard.

^^ (use these "pins")

Since one way to view the problem is that the motherboard connector is
on the "wrong side" of the PCB (causing pin 1 to map to pin 2, etc),
couldn't you do make a cable like this...

--------------------

Wouldn't that simulate having a connector on the wrong side and reverse

AFAIK, there is no ready source of 12V. Also, consider the power draw. A
laptop drive pulls 500-700mA (2,5-3.5W), a desktop drive draws closer to
9W-15W. It's even a consideration when choosing a different
CPU (ISTR the WinChip180 is rated at ~9W, most Pentia suck around 13-17W).

It depends on what you mean by required. According to the VMS FAQ
("ftp://ftp.digital.com/pub/Digital/dec-faq/OpenVMS.txt", topic VAX5,
"What system disk size limit on the MicroVAX and VAXstation 3100?"):
[...]
Systems that are affected by this limit:
o VAXstation 3100 series, all members. No PROM upgrade is available.
===========
[...]
Generally, as I understand it, the corruption results from the
firmware writing to a too-large disk, as when a crash dump file is
written. As the firmware on these machines mentions both ULTRIX and
VMS, I assume that it is comparably adept at wrapping around at the
1.07GB limit and corrupting a disk with either style file system.
Disks larger than this limit are fine as data disks. (I have a 4GB
disk in my model 38, for example.) They also work fine as system/boot
disks, until something goes wrong, and the corruption occurs. (I boot
my model 38 from a smaller, safer disk.)

Does anyone have a working NEC PC-8886? I think this is the model
number. It may very well be an NEC APC. At any rate, it would be a
model with 8" drives.
I have some 8" disks (I believe they are single-sided but the box they
came in says "2D" on it; they are 256 byte sectors) containing some
valuable geological data for the country of Guatemala that I am trying to
recover for a geophysicist working on a project in conjunction with the
UN. They contain graphical maps and textual data that would be very
useful for Guatemala.
If anyone can loan me a working NEC computer that can possibly read
these diskettes I'll be sure you share in any praise heaped upon us by
Guatemala, and I promise to share any villager women they bestow upon
me for my efforts. In the very least shipping costs will be reimbursed.
I have an NEC PC that would probably be able to run whatever is on
these things (providing they are still viable) but it doesn't work. In the
meantime I'm going to go retrieve it from my warehouse and see if I can
fiddle with it and coax it to be reborn.
Please reply directly to me as I am not subscribed to ClassicCmp.

Only the oldest 2001-x PETs use those SRAMs. I guess it's time to build
that upgrade board (a PAL, a pair of EPROMS, and some 6264s, a 62256, or
some cast-off PC cache).

Thanks Allison,
It has been a while since this--and I don't even have the
machine anymore, but I guess I can consider this debunked.
At the time it was VMS-5.5.4. I was using the machine as
an X-terminal for want of it running real-X.

Conclusions for the archives...
It is entirely possible to put non-DEC third party drives in the VAXStation
3100/M76. I have recently installed two 2.1 GB "Barracuda" drives in them
and they are working flawlessly. The steps are:
Install the drive, select an ID that isn't being used on the SCSI bus.
Run the PROM based formatter on the drive using "TEST 75" to the monitor.
Install your software on the drive.
On the M76 there is no requirement that the boot disk be smaller than 1GB
(apparently this is true on earlier models).
This looks like it will turn out to be a good NetBSD development machine as
it is reasonably fast (7+ VUPs), and reasonably compact as VAXen go.

No, unfortunately they're about as different as you could get, for that
era. MCS6550 is 22-pin 0.4" wide static 1k x 4; MCM6665 is 16-pin 0.3"
wide dynamic 64k x 1. Thanks for the offer, though.

One of the MCS6550 RAMs has gone west. Does anyone have a spare, or an

Saw the recent request for info on the Sharp and want to add my name
to the list for info.
also looking for info on the Wang WLTC. Picked up one with no power
supply!
Hello group,
These were given to me recently by another member of this list who also has
no use for them (thanks, Pat). They can be yours for 1.5 times shipping
cost. All are in great condition and I have no reason to believe they
shouldn't work. Specifically, what I have are:
Quantity 3 Allied Telesis / CentreCom model AT-280 (2-port transceiver
fan-out)
Quantity 3 Allied Telesis / CentreCom model AT-480 (4-port transceiver
fan-out)
Quantity 3 Canary Communications model F 4000 Rev.B (4-port transceiver
fan-out)
All are DTE powered and "can be installed with any existing standards-based
transceiver used in thicknet (10BASE5), thinnet (10BASE2), fiber optic
(FOIRL) and twisted pair (10BASE-T) installations".
Summary information on the Allied Telesis units can be found at
http://www.lantech.nl/products/ati/fanout.html and technical information and
manuals in pdf format can be found at
http://www.alliancedatacom.com/allied-telesyn-products.htm by using the
site's "Search Site" button and entering either AT-280 or AT-480.
Information on the Canary transceivers can be found at
http://www.canarycom.com by searching for F-4000 and using the first link in
the returned list. Information in pdf format for the F-4000 can be found by
using the eighth link in the returned list, under Transceiver Products.
Please contact me off list if interested in one or some for your own use.
Please don't ask if your intention is resale.
I realize these aren't vintage yet, but I know some of you can and will use
these in networking vintage equipment d8^)
I'll post to the list when all have been spoken for.

In today's thrift store trek, I came up with a Wico trackball for my
C128 and one of those cute little Apple //c mini monochrome composite
monitors which in the ultimate irony will go to the 121-colour Commodore
Plus/4, which has been sharing a Commodore 1902 with two 128s.
The other thing I found was an Atari XE GS with no power supply or
peripherals. Since it was only $2, I picked it up. Aside from being
dusty, it looks to be in good shape, so I'm going to try to clean it
up. Can anyone tell me about them? How unusual are they? What is the
pinout on the power supply (it's an 8-pin DIN)?
>From the looks of it, it seems to be a 65XE in a case with no keyboard
and just the regular Atari function keys (OPTION, etc.). I've heard
of them but never actually seen one, and I don't know too much about
the Atari 8-bits to start with. I assume it takes 5200 and regular
Atari 400/800/1200/etc. cartridges and the usual Atari/Commodore joysticks.
I'm also interested to know how uncommon they are.
Thanks for any help!

Not yet... they are out of stock nationally (due to the ./ effect). Mine
is on order and won't arrive for at least a week or two. I've heard that
Netpliance is evaluating how to reword their ads/sales agreements/etc. to
make the idea of hacking one less attractive because they are currently
subsidizing a $300-$400 machine to sell their ISP service. If you order
one direct from the company, they "include" the first month's service on
the sale, but you can cancel after that. I'm wondering if they will go
to a rebate sales model - buy the unit at $300-$350 and get the first year
on the 'net "free".
In any case, I'll be getting mine eventually. One of the nicknames for
the box amongst the hacker community is the "iOpenedIt".

Hi, folks,
Well, I've run into a snag. Turns out my oh-so-slick Livingston router
won't do ARP proxying along with NAT (both of which are needed to deal with
my DSL hookup for adding servers).
So, I'm going to build a router that does out of an old PC box, a couple
of Ethernet cards, and either Linux or OpenBSD. My first question: Has
anyone on the list done ARP proxying with a home-brew router and one of the
above OS's?
Also, at the risk of venturing slightly outside of the "classic" realm
(not by much -- two years or so if I'm not mistaken), I'm looking for the
100Base-T media module for the Compaq NetFlex-3 NIC. Anyone?
Thanks in advance.

The only thing stopping me it it hasn't arrived.
Heres the scoop:
Its a P180 (winchip, socket 7) with 32mb ram internal DSP modem and
16mb of Flashram. There is also an IDE port for 44pin 2.5" drives
(connector is mirrored pinout so any cable has to fix that. The
flashram beomes IDE-1 if there is a disk. There is USB and a Parallel
port, potenitally a second unused serial port. The video is Trident I7
driving a 10" dualscan flat pannel color LCD. The Video memory is
mapped to the main memory map (flat). Looks like it would make an
excellent lowend linbox, Winbox or whatever.
The present OS is QNX with their browser and email client, fixed target
of netplience (or their agent). The QNX demo is about the same thing
as Netplience. Anywho it's what in the Flashram obviously of fancier
quality than the demo.
The suggested application a week ago was a microkernal and a emulator for
whatever prefered Hardware/OS comes to mind. One suggestion was Supnik
or John Wilsons PDP-11 emulators and PDP-11 unix. One I've giving thought
to is DOS/MYz80 to make a really nice CP/M crate.
Oh, there are a dozen or so web pages on hacking it.

Are you _sure_ it's 300 baud? I thought it was 2400. We had a 20K byte load
module that took about a minute to load - this corresponds to a little over 300
_bytes_ per second. Same load module from tape took SEVEN minutes! No wonder
speed loaders and things were popular! (Typical disk speed loader used 2 of the
wires in the serial bus for data, doubling the throughput. May have used higher
baud rate as well - I never had problems with 4800 baud in software on a PET.)

Hello ClassicCmp and Port-vax,
I am trying to track down the compatibility of the VS3100/MS SCSI bus with
"modern" SCSI drives. The case in point is that I'm trying to connect a
SeaGate Barracuda (ST32550N) drive (2.54GB SCSI) to the internal bus,
replacing a 426MB Seagate drive. When the drive is installed the system
gets indigestion. I'm currently attempting to disable parity on the drive
in case that is an issue.
Has anyone done something similar? Is there some caveat I've missed?

Subject: Old Kaypro's Home?
Can't bear to throw my old Kaypro II and manuals in the dumpster.
Does anybody out there want it or the Okidata 92 that goes with it?
Would any foolish old sentimental collectors want parts for their

Any suggestions?

This is an integrated file server that runs a hacked up
version of MS-dos, along with 3+Share, which was 3Com's
Networking software. It came standard with a 70Mb
hard disk, 60MB tape (Wangtek 5099EN24) and 800k memory.
It differs memory-map wise from the PC in that, of course,
there is no ISA bus nor video adaptor, hence they could
allocate more memory to MS-DOS.
You could get a Cache card for it, which allowed LIM 3.0
expanded memory operation for disk caching. The 3Server3
uses an 80168 cpu at 8Mc (IIRC).
I used to make a fairly decent living maintaining these;
then Novell took over, and we all know what happened after
that.

There was no skunk box version of the board (meaning it has the
S-box handles)... but there is a skunk-box version of the
break-out panel so that one can be used... I have one such
unit on my uVaxIII at home... works just fine...
And yes, the cable with the right-angle connector is required,
otherwise the cabinet front won't close...

On the SCSI drive, disabling parity made it work. Without parity disabled I
would get a machine check ?21 CORRUPTN. Weird, DEC usually leans in favor

I would like to know what material can

3.5 floppies when these are missing,
on the right hand top corner.
We used PDP 11/04's with a cassette drive to collect microbiology data.
There is nothing more frustrating than coming in in the morning and finding
the cassette tape drive trying to write to the cassette and rocking back and
forth on the same spot until the oxide is worn off. We didn't have enough
memory to store all of the data in the PDP-11 and there were no disk drives
in the system. The entire program was loaded into a PROM and booted the
machine. It was one large program that monitored the incubator, moved the
test kit carousel, removed the cards, read the optical transmittance, and
did the data analysis. The console was a VT-52 with the hard copy option.
Even earlier incarnations had PDP 11/05's with core memory.
I seem to remember that we were excited when the RX01's came out, we
purchased DSD versions and wrote the data to 8" floppies. We wrote data to
the correct sector and when we were done the data was in a RSX usable file.
What memories.

The C64 Serial _PORT_
The C64 Kernal does have routines that implement a serial port
using certain pins on the C64 User Port. But if you don't mind
writing your own driver then theoretically speaking all you
need to implement a bidirectional serial port is two bits on a
port with the capability of defining one as input and the other
as output (the input bit should be capable of generating an
interrupt), and a ground reference. And if you want RS-232C
signal levels (many computers and other serial devices are
just fine with TTL level signals) you need to add a RS-232
driver and receiver to the interface. Back then that meant
the 1488 and 1489. Today you have the ADM202,MAX202 and the
LT1181.
There is a problem with the C64 RS-232 Kernal routines. It
turns out that the time they take to process one bit plus the
timer value for one 1200 baud bit time was slightly more than
one 1200 baud bit time. By the 8th bit, the timer interrupt is
happening more than 1/2 bit time late, missing a bit. This is why
in the early days (before 1985) people had to set the serial
port speed to 1210 baud in order to receive reliably at 1200
baud. And of course you really needed two stop bit time to
to prepare for the next byte. I really believe that our group
wrote the first serial driver to allow the C64 to run full
speed at 1200 baud.
If you don't need interrupt driven serial routines, we use
to do our software development on the Stratus and then download
to the C64s in our offices using a serial cable that plugged into
one of the joystick ports. Software in the C64 would bit-bang
the joystick port at 9600 baud (with the screen blanked).
The C64 Serial _BUS_
All fast serial disk software for the C64 can actually be
traced back to those clever C64 users in Germany, they did it
first. I reverse engineered the Epyx cartridge about 1985.
Yes, bits were transfered two at a time with another line used
to to signal "ready to receive a byte". I do remember that the
intrabyte transfer time for two bits was 10 clock cycles. That
doesn't include any of the byte setup time. We were loading
just over 50K in less than 15 seconds.
The real trick to fast disk routines without blanking the screen
was knowing not ask for a byte to be transfered from the disk
when the video chip was drawing every 8th scan line. In the C64,
the video chip causes a DMA at the end of every 8th scan line
to access video ram and get the information for the next 8 lines.
This tristates the 6510 for 40 clock cycles and no instructions
can be executed.

Since floppy drives no longer use optical sensors, using a mechanical feeler
instead, you may find that the write-lock tabs that you once used on 5-1/4"
drives work fine, so long as you apply them so they're tight. That way the
feeler will encounter resistance when it tries to feel the hole.

AFAIK, it is _not_ a regular cassette but the drive mechanism is based on
regular cassette transport hardware. The media is coated for low friction
to extend media life and reduce head wear, among other things. One minor
feature of the cassettes themselves is a plastic flippy write-protect tab.
Not essential but a nice touch.
As has already been pointed out, the cassettes have a notch in the middle
of the top and there's a finger or a block or something at the corresponding
location on the drive preventing you from mounting an audio tape.
I used to use tapes by the crate on my PET way back when. A regular speed
tape drive mixed with cheap Rat-Shack tapes was a dangerous combination. I
wouldn't want to use consumer grade tapes with a high-performance mechanism.
It makes me think of the nickname of the TS-11 - the "Tape Stretcher 11",
maybe a "Tape Annihilator 60"? :-)

Hi
Another question.
I'm trying to put back in service PDP-11/05 used to controll aircraft
structural test sytem. I's equiped with DECcassete drive (it looks like
normal audio cassete).
Is there any replacement for them ? I mean using good audio casset or
so.

Same or similar. At one time I was doing cassettes for data storage
(ca 1975-76) and still have my Redactron drive and also MPI plus a few other
scraps.
There were two major schools on the drive, capstan driven (PHI deck) and
reel to reel drive. Obviously one was constant speed tape and the other
without elaborate electronics were constant data rate (more or less).
The tapes themselves were different length, formulations and even front
coatings. Compatable... barely from the same drive.

True, while they would work for a while eventually they stretch though
some audio tapes were thicker. Also most audiotapes had huge dropout
zones where the recorded level would drop significantly.
Also the saturation recording was nothing like audio recording in how the
head was driven or the read back signal. The closest thing we have now to
the recording technique used is floppies.

After since the newspaper article about my collecting was printed in the paper I have been getting calls and emails everyday with someone wanting to give me something. Here's a short list of some of the items I have picked up:
1. Lisa II complete and working with manuals and tons of software.
2. complete Mac IIcx in the box with Apple monitor also in it's box.
3. Prototype scsi tape unit for Apple done by 3M with tapes loaded software. The guy wrote the firmware for these drives that gave a box full of Apple stuff.
4. Complete Mac Plus system
5. Lots of books and manuals. One really nice one is a special Promotional Edition of Inside Macintosh dated 15 March 1985. The pages are made of thin tissue paper and were given to programmers at this guy's shop which purchased a large number of Lisa from Apple early.
6. Several IBM PS/2 systems not yet 10 years old.
7. Several printers, ink jets and dot's.
I still have about 6 more systems and other items to pick up from various people that have called. Now if someone would just give me another warehouse to store this stuff in. Keep computing John
I have set up my terminal server and put a PDP-11/35 with RX02s running

If someone is already there then you will probably get a connection error.

I will be putting online a PDP-8/S and a PDP-11/20 in the next couple of
days so I need to make sure everything is okay.
Please e-mail me: dylanb(a)sympatico.ca after you try.
Some useful reminders:

Caused, IIRC, by Tramiel who demanded of the engineers that the next computer
not use the same connectors because of a supplier shortage at some point in
the PET's past (dunno if it was the edge-connector end or the IEEE-488 end
that was hard to come by, but that's the story that's been circulating for
twenty years).

It is, effectively, the same character protocol, but the serial bus is
lacking in some of the handshaking lines that characterized the true IEEE-488.
There's a great book on the PET and its implementation of the IEEE-488 bus
by Osborne Press. If you ever see a copy of it at a bookstore or flea market
and have even considered programming for the PET, grab it.

It was because of this slowness that at one company, Software Productions,
we compressed the menu and splash screens for our C-64 version of "Micro
Mother Goose" (sold under the Reader's Digest label). It was a simple RLE
compression, but it cut the pictures down about 70% (lots of black space around
the menu items) and decreased the load times significantly even accounting for
the extra code to decompress the images. We had plenty of RAM and loads of
disk space, it was squished purely to speed up the load.

I'd have to check. I know I have the one Unibus controller. The next

Right. Device classes have access types, and you can't put device

Yes. You want to set the logical device up like something like this:
TYPE? 32
SUBTYPE? 14 for direct connect, 15 for modem connect
ENTER [TERM TYPE#], [DESCRIPTOR FILENAME]? 18 or maybe 20, not sure
SPEED IN CHARACTERS PER SECOND? depends, use bps/10
RECORD WIDTH? (chars per line)/2
OUTPUT DEVICE? 0
ACCEPT JOB/SESSION? no
ACCEPT DATA? no
INTERACTIVE? no
DUPLICATIVE? no
INITIALLY SPOOLED? can be yes, can be no
INPUT OR OUTPUT? out
DRIVER NAME? HIOASLP0
DEVICE CLASSES? probably LP
Regarding "initially spooled": if you say yes, I'd set a high OUTFENCE
(probably OUTFENCE 13) in SYSSTART.PUB.SYS so that the spooler won't
try to start printing spooled output right away on boot (which might
lose output if the printer is switched off or disconnected). The
alternative is to make the device not initially spooled and start
spooling manually with a STARTSPOOL command. I think I like initially
spooled with high outfence better.

For dome timre I'm trying to connecyt my VAXStation 3100 to PC runing
Linux via TCP/IP and thin wire ethernet. I got TCP/IP services
(origanal Digital's tcp/ip for OpenVMS 7.2) running and passing all
internal test. However I can't get connection. I suppose the problem
is in network interface.
Interface passes boot time test and i can get it's hardware addres, so
it is OK I hope. The swith on the back of unit is set properly - the
green LED is lit on side of BNC connector.
Using '$ SHOW DEV' command I can see one network interface 'ESA0:' which
is online and labelaed as 'template devece' (whatever it means...).
After starting up TCP/IP I get two other interfaces 'ESA3:' and 'ESA5:'
owned by processes related to TCP/IP services.
Does anybody know what I've to do to get my network up ?

So, I set up the printer up as a terminal (don't recall type and sub-type)
and it sorta worked. I think some of the control sequences are not quite
right. I'll have to tinker with it until I get the right combo. Is it
possible to set it up this way and still have the print jobs spooled?
Hi everybody,
Just wanted to let you know that the retrocomputing web site I've been
working on,
http://www.retrobits.com
went live, as scheduled, yesterday evening!
Thanks to those of you who helped out with the collecting survey. And
for those who haven't filled it out but are still interested in doing
so, there is still time. There was so much material, I broke the
article into three parts to do it justice. Parts II and III are yet to
be written, and if any new points emerge on Part I, I'll update that
section also.
The site's premiere contents include:
- Vintage Computer Collecting, Part I
- An Interview with Cameron Kaiser
- Book Review: "Apple - The Inside Story of Intrigue, Egomania, and
Business Blunders"
and of course, Cameron's world-famous Commodore and Tomy web sites!
Please visit the site and let me know what you think. And bear in mind,
it's my goal to make the site increasingly interactive over time. I
want nothing more than to make this a useful, community-driven
retrocomputing resource. If you've got ideas for information, articles,
and other resources you'd like to see, please pass them along.
And if you've got any questions or concerns, please don't hesitate to
contact me.
Thanks,
Earl Evans

I agree. I recommend putting up a link on a webpage like mine and then
updating it with an IP poster. My IP numbers change *very* rarely but it is
a good idea to still use a link on a webpage that is updated by an IP
poster. I still recommend using a Windows box for the job, a cheap 75Mhz
Pentium with Windows 95 will easily handle 7 TELNET connections at 9600
baud. I am moving mine over to a new Celeron box tomorrow morning for
dedicated 24/7 connections to my PDP-8/11s
http://www.pdp8.com/1135.htm
Anyone here have any vintage software to run on a PDP-11 as a front end
connection server? Waterloo University used a PDP-11/45 back in the '70s in
front of their *huge* cluster of some 3-500 DEC minicomputers. I've got
heaps of DZ,DL,etc.. from the warehouse so serial ports are not a problem.
Expect the first version of DOS/BATCH-11 next week.
No electricity costs here ;-)

I've adopted a couple of MV3100/M76's in my quest for different VAX
hardware :-)
Having been using Q-bus VAXen for some time these have some mysteries that
I would like to explore.
First boot sequence, I know there is a list of boot errors somewhere, I
remember reading it but it isn't in any of my VAX book marks. I get these two:
? C 0080 0000.4001
? 6 80A1 0000.4001
The next mystery is the SCSI connector on the back. It isn't SCSI-2, what
is it?
I also got an expansion box (big fat SCSI I connector so no connection
there) with an TZ30 in it, can I move that into the M3100 for now? Is that
a supported config?

Nope, I don't have the software, but one of my 11/23's was originally a TCP
(see below) at Edinburgh University.

Edinburgh Regional Computing Centre (part of Edinburgh University) used to
do something similar. According to the chart I still have (dated 1985),
ERCC had eleven 11/10s, eight 11/23s, three 11/40s, and a few 11/34s and
11/03s connected as Terminal Control Processors (TCPs, basically front end
processors for fixed or dialup terminal lines). I'm not sure what the
interfaces were, but my 11/23 had a pair of DLV11-Js when I got it, and
originally a synchronous line as well (which I think went to a GEC packet
switch). ERCC also had an 11/34 and an 11/40 connected to the central
processors to handle "slow devices", and fourteen CAMTEC PADs, as well as
several VAXen, other PDP-11s running RSX, a few Systimes, a few Pr1mes, a
couple of DEC 10s, an Amdahl 470, a few big ICL 2900 mainframes, a few
GECs, and at least one Data General machine.
Altogether, Ednet supported 33 local host systems, 100 synchronous and 1521
async connections.
Leeds University also did something similar, up to about 1992. They had
three 11/34s with (AFAIR) 32 serial lines each (mostly Emulex devices)
feeding a pair of DX11s into a big Amdahl. The 11/34s ran some homegrown
software, booted from an RX02. There was also a couple of 11/73s, one of
which was in a proprietary unit that incorporated a DX11-alike on two (or
maybe three) Q-bus boards. That one also had some wierd CAMTEC ethernet
interface in it. I've got one of the 11/34s, and one of the 11/73s; one of
my friends has one of the DX11s.

As all most of us "Old-timers" know, when you read a prompt that reads "To
continue, press any key", pressing any key on the keyboard will take you to
whatever is next. I read recently that on a few Compaq keyboards there
actually was a key labelled the "Any" key! Now *that's* what I call
idiot-proofing! (iSore, eat your processor out!)

I have a number of these as well.. I believe that the HDA can be
used with either an RZ (SCSI) or RF(DSSI) board...
Make sure that you know for sure which board it has on it... both
types will say 'rz35/rf35'...
Easy way to know... the power connector will be 4-pin for SCSI
and 5-pin for DSSI (at least all the ones I have are like that).

DSL is in and functional, at least at a basic level. I can't -believe- the
speed increase!
With basic router configuration dealt with, I'm going to (over the course
of the next couple of weeks) get the servers and DNS authority taken care
of. I'll post a note when I have my domain entirely under my control.
Honestly, I'm surprised the router configuration was as easy as it was.
Definitely something to be said for Livingston boxes...
Gotta run back to work for a while. See you lot later!
