Yup, the language was indeed PILOT, which was a language focused on CAI (Computer Assisted Instruction). It was written in BASIC (a pretty large series of programs) on the HP Timeshared BASIC system. It was used quite a bit in the Chemistry and Math curriculums at the high school I went to run courseware for these classes. It annoyed us computer guys, as it meant more kids coming in to compete for the online 33ASR TTYs!

Hello list,
spotted this video recently on youtube:
https://www.youtube.com/watch?v=ZQzDSOXHd70
It's a Xerox Digital Systems mainframe! Wow, I didn't know that such installations were still running as of 1997!
The computer room is quite untidy. Andybody has an idea, where with was filmed?
There's also a Data General minicomputer and Honeywell mainframe equipment.
Can anybody identify the Honeywell stuff? It's Level 6000 style, but
it's strange to me that there seems to be just this one cabinet along the
rest of the XDS equipment. Maybe a Datanet option?
There are *very* nice close views on running CDC disk drives using the 100/200MB disk packs.
I was looking for a long time for a video actually showing how the big head actuator
of these drives moves when performing data operations!
And there are nice reel tape drives which look to me like rebadged IBM drives (not sure, though).
Enjoy watching it! I did!
Kind regards,
Pierre

I'm looking for a cable or cable pinout to get the console of this 11/03
going. I figure to ask the simple question here rather than dig my self
a hole trying to puzzle it out or guess the solution.
http://jimsoldtoys.blogspot.com/2015/11/pdp-1103-system.html
It has a M7940-YA DLV11 controller. I hope to get it working and run
thru some testing of the other boards I've accumulated and sell one back
off to end up with a working system.
I'll probably be in the market or need to try to set up a floppy drive
as this appears to have a floppy controller to also have a bit more
functionality.
Right now ODT and some fun would be nice.
thanks
Jim

Okay, this is where things get cool. For you folks who have issues with
javascript heavy pages, I don't recommend clicking the following image
links.
The teletype is connected to one of the original 300 baud Hayes Smartmodems
I had in a box doing nothing which solves a lot of problems with trying to
make an older dataset work with the much more plentiful Smartmodems and
their later clones by just about everyone. (which as a few have mentioned
have no issue working at 110 but with a catch) That I've found so far you
can dial pretty much any other hardware modem that isn't relying on a DSP or
sound CODEC (so late ISA and all PCI cards don't work) and it will work by
pure modulation. You just need to make sure the COM port on the machine is
set for (or will automatically detect and switch to) 110 or else it assumes
300 and nothing works.
The quirk I added however is that I took the guts of the teletype's UCC6 and
a TWX controller and built a custom CCU that gives me feedback on the modem
status and lets me control and dial from the front panel. The modem itself
now hides in the stand and I don't need to type in commands to do anything.
It looks as if it's a factory option. I even added a feature where in
Automatic Answer mode the motor is relay controlled by the modem itself.

I have a massive writeup and a video that are about ready to go live but I
need a set of videos demonstrating the setup connecting to a remote user,
connecting to a remote machine and a remote user dialing into the teletype.
That's where I was having my troubles.

People have been nagging me for the last year to get a Panasonic 308. I've
yet to come across one so far that wasn't weirdly priced, plus my parents
aren't interested in a PBX being installed in their house.

Large HP boards from the 70's. This sounds just about perfect. This one
would have fit the description of a HP 1000 mainboard pretty well. Medium
sized ones too. Anything HP from the 70's or early 80's for that matter.
Bring' em home!

Hi Guys
1 Real 8/e panel as absolute check leaves US on its way to
me to-day
2. Out of twenty slots sixteen have gone. That leaves four.
If they don't go before printing starts I'll have them
screened to uncommitted /e (can become A or B)
3. For me its back to PDP11/40 thru 11/70 layouts.
4. Anybody need a one off. I'm trying to find an economic
way to handle custom jobs
5. I'm also looking at an option to put manufacturing
locations on as found on some systems (default is Maynard)

Drat!? I just bought one for $10,000 last month.? Could have saved enoughfor a $5000 Lisa mouse.

No u couldn't Bill as that price is in sterling not dollars :)
I was just browsing eBay for stuff near me when I came across this:
http://www.ebay.co.uk/itm/Apple-Color-Plotter-/291611803288
I don?t know anything about Apple stuff at all, but surely ?5,000 for this
is a bit optimistic, isn?t it?
