I have set up my terminal server and put a PDP-11/35 with RX02s running
RT11v3.0B on the Internet.
Please visit this page: http://www.pdp8.com/telnet.htm and click on the
link.
If someone is already there then you will probably get a connection error.
(soon there will be 7 available ports - only 1 now)
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:
Hit ^C (Control-C) when you connect so you can abort any program running.
type BASIC to run basic... it has some games online.
type "BYE" to leave basic.
Thanks again!

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?

Did you do "@ SYS$MANAGER:TCPIP$CONFIG.COM"? What are everyone's IP

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 ;-)
