Sorry for the shotgun-style forward, but this just came across classiccmp,
and I thought it might be of interest here.

I have about 25 BA350 style enclosures, BA35x power supplies, and
RZ24,25,26, 28,29,40, etc. Some are in canisters, some are bare drives.
I'm trying to clear a path and it's all in my way. Take one or all.
shipping from IL, 61853. Please contact me off list
Thanks, Paul

Yah, it was 6 bit tape for text preparation, with 8 bit tape used for
programming & setup of the phototypesetters. Meant a lot of messing around
with the tape readers, since one width of tape expected the feed holes to
align with the center of the data holes, and the other width expected the
feed holes to align with the leading edge of the data holes.
Speaking of Flexowriters, we had one of those for doing commercial mass
mailings that looked typewritten - I still have one of the 576 bit core
memories it used. Each memory board was about 8X11 inches. The individuals
cores are really big on these boards.
Good times...when you weren't dozens of levels removed from the actual
physic of computation.

How many people on this list have ever used paper tape at a job? My first
computer job we used it to control phototypesetting machines. When an 11/70
was added to the mix of gear there, we ordered it with paper tape readers
and punches on it to help in transitioning away from the paper tape only
gear it was replacing.
That was probably 6 bit tape -- most typesetters I've seen that were fed
with tape used 6 bit tape.
My first programs were written on paper tape -- Flexowriter editing
papertape typewriter/reader/punch machines, with a character set optimized
for Algol 60. That was at the Technical University Eindhoven, then known as
THE -- which is where the operating system by that name came from. It was a
batch system: paper tape in, line printer output. Magnetic tapes available
in theory but rarely used, plus a drum for paging. Processor was a Philips
(Electrologica) EL-X8, a 27 bit machine with a rather exotic I/O
architecture that I never really understood.
BTW, Flexowriters are great machines. Teletype Corporation never built
anything remotely as reliable as those -- certainly not the cruft known as
Model 33, and even a Model 35 isn't as good.
Semaphores (in the computer science sense) were invented there.

Hello!
Interesting. I recall a PDP-8 based system who accepted 8 level (or 8
bit) punched paper tape from a terminal and also for composition. That
was fed in through the reader on a Model 33. Naturally after the
terminal (the teletype) would cue the operator that the system
finished reading the job tape, it would then create one containing the
composed work, it would the be fed to a Merganthaler VIP, and the
output device would run.
The terminal who did all that as it happens ran its programming via an
Intel C8008-1 processor. The PDP-8 was a PDP-8E.

It's ham parlance, CW shorthand, that basically means "seeya, have a

Actually it means "Regards" or "Best Regards".
Oh good heavens. Same sentiment...and used in exactly that way since well

I must have used the same image you are talking about. I had to BRU it to a bigger disk first to avoid running out of headers during the netgen.
Ah, I didn't save the mail message, but it involved setting the machine type in simh to 11/93, so a TOY clock is available, and commenting out the time setting dialogue in [1,2]startup.cmd. That and putting the command "boot rq0" as the last command in PDP11.INI were enough to take care of the SIMH and RSX startup issues. Then I added an @reboot event in crontab that does the pdp11 command to start simh, and viola - RSX sunning whenever the power is on.

How did you do this, do you have the tape images? I have a pre-installed disk image for 4.6 but my NETGEN failed on it due to lack of file nodes and it needs migrating to a new disk with more nodes.
I ve gotten RSX startup automated on PI power up thanks to a HECnet list discussion from a month or so ago.
Could you point me to the relevant archived mail conversation? I'm trying to do this myself with VAX and PDP-11 emulations :)
I d like to automate the startup of DECnet as well, so it all comes to life whenever power is applied.
What s the hot setup for automating this? I never had DECnet back in the day when I was managing 11s, so I never got to look into the best way to go about this.
Your bootstrap startup file is STARTUP.CMD - I think if you tack the command(s) (which I have forgotten, damned addled brain) in at a late but relevant position in that file it'll fire off when you bootstrap RSX-11M+. I used to have one of my previous RSX-11M+ 4.2 emulations setup this way.

Did they call ANF-10 DECnet phase 1?
-P
For historical amusement...
In reading the Phase II NSP spec, I spotted a summary of how that differs f=
rom Phase I. I've never seen any Phase I documents (perhaps no formal docu=
ments ever existed?). From the discussion in the Phase II spec, it's clear=
that Phase I is quite a different protocol. Phase II through IV are all v=
ery closely related, especially at layer 4 and above. Not so Phase I -- it=
would be quite difficult (at best) to make an NSP implementation that coul=
d speak both Phase I and Phase II. I don't see any signs that this was eve=
r done. For example, there is no "how to interoperate with the previous ve=
rsion" chapter in the Phase II spec -- unlike the Phase III and IV specs.
