Hi,
Can someone point me at any documentation for installing/configuring the
tcp/ip package for RT-11? I got the pkg file and have looked at the
contents, but a little bit of doc would go a long way at this point...
Thanks,

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.

Anyone done this yet?

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.

That's all true. I've been using it for a while and have even put together

There are a couple of versions out there. I know the older one, 2.9.3. Write

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?
Obviously the DEC manual isn't much help :-)

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
of error detecting/correcting protocols.

I don't have any figures for geometry or access times, but I do know that

I would like to know what material can
be substituted for the black slide on
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.
Just my $.02

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"? :-)

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.

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

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.

Hi Does anyone know of a FAQ or other document which describes the HP Apollo
(700 series?) and/or the HP-9000 series of PA-RISC machines (9000/7xx?).
I've had a look around but can't find anything, even on the HP site (just
details of the latest machines).

I'm interested in a couple. I have the same arrangement - 11/05 w/TU-60 and
one whole tape!

I'd have to check. I know I have the one Unibus controller. The next
time I get to my secondary storage location (friend's basement ;-), I'll
check if there's a second card in my Unibus pile. I've always been
curious how a TU-60 performs on a PDP-8. Anyone ever use one?

Right. Device classes have access types, and you can't put device
classes with different access types on the same 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 ?

I hooked up a serial thinkjet to one of the ports but didn't get the
configuration just right. Originally, I tried to configure the serial port
as an "LP" device but, the system balked. It said that I couldn't mix device
types on the same ATP controller. In other words: If I have a TERM attached,
I couldn't have a LP attached at the same time.
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.

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!
