In the video the macintosh I referred to was the apple I was eating; of course, it also indirectly referenced the computer that was a decade away. Glad you liked the admittedly corny video!
The tape save and tape load procedure is similar to how sound waveform data on electronic music synthesizers can be saved to cassette tape and loaded from cassette tape. They make a unique sound as each sound program is saved to tape. A high beep is a 1 and a low beep is a 0. It's amazing to hear sound program data flying in the air. :) Cool paper tape! Retro computer! :)
@FuyuAkiWorld Yes, it is a real, working PDP-11! I acquired it in the 1980's and keep it running. It's impossible to purchase paper tape now, so I don't punch tapes too often, but it does indeed still work.
Actually, in this paper tape system PAL-11 produced a loadable image. The one thing I did simplify in the video was the loader. Technically, one had to toggle in the bootstrap loader, then use it to load the absolute loader which was used to load all other images. In the video I suggested that the bootstrap loader could be used to load all images.
A nice way to give some perspective on how easy we now have it. Then again, I could edit paper tape programs by cutting out or splicing in other sections of tape. So it had some benefits.
Yeah but now we can use vim or whatever other text editor you want to splice together large sections of files in a few keypresses, no scissors required.
He didn't explain how he changed the execution of the computer between re-running the already-loaded loader and re-running programs multiple times. I hazard a guess that the user toggling between programs in this way is actually computing's first user-mode kernel-and the architecture includes a human user.
Never ran across a PDP-11 that didn't have disk and RSTS/E on it. Very interactive machines. My first was a PDP-11/70. But I'd also gotten to play on a PDP-11/34.
So, is there an operating system at all, or does it just run one program at a time, off of the paper tape (or front panel toggle switches)? In any case, it's a fun video. Nice job.
@numba1netsfan TOriginal systems and components show up in the retrocomputing marketplace every now and then. In the nineties they gave them away for free or put them in landfill, but thanks to the collector market, now complete working systems go for thousands of dollars. They require specialist technical expertise to keep working, though, and are better suited to a museum. Newer (mostly) binary-compatible machines from the eighties and nineties from Mentec are also available.
That's pretty neat, but you didn't show us how to load in papertape when you run out of papertape, or what happens when you run out of tape halfway through punching something! . &eB
300 Bytes per second. That's only 100 Bytes/s slower than a standard Commodore 64 1541 Disk drive (without fastloader). The PDP11 btw has a very neat instruction set. If you look at it, you can easily see that the Motorola 68000 engineers (my favourite CPU) ripped it off almost completely.
The part which I don't get is how do you EDIT the existing program using a screenless terminal? It's impossible to go back and forth through the code on a teletype!

Thanks for making the videos.
And I think I can appreciate why you have collected and maintained that big iron:
It's awesome!
Thanks for this info. It's a excellent guide to start Programming on PDP-11 computer.
In a world without walls or doors who needs gates and windows

"What can I say I'm a nerd" i lol'ed.

Lol to the ending. Hahaha
Good videos!
God this guy needs to chill out. What's the rush, geez.
tnstafltph time machine's running out of power
He jelly because the cute chick is having fun with PDP Guy and ignoring him.
Wow, I remember paying $40 for my first two pass 6510 assembler. Came on a homemade labeled 5.25 disk.
Yes, I’m a nerd. However, I think I’m in love. Wowza!
The nice lady is pretty cute, too!

I LOL'd at the McIntosh apples
@DouglasHarms wow, that's awesome! You're so lucky!
Cool 👍🏻
I like the Apple Mac reference at the end.
So, is there an operating system at all, or does it just run one program at a time, off of the paper tape (or front panel toggle switches)? In any case, it's a fun video. Nice job.
@vleon1012 yeah. the first mouse wasent made untill the late 60s. and even then they weren't mainstream
these are some nice videos. it's very interesting to me. and I have to ask this, is that a real PDP11? If it was, that'd be SO awesome!

What I would do to own one of these systems!

Many consider PDP11 assembler, together with the 6502 and 68k, as the best instruction sets there were.
@aure232 windows rocks!
@aure232 Windows rocks! Without Windows, Macs woulden't be the same. The OS would be WAY different. it probobly woulden't even be a GUI.
@FuyuAkiWorld it wasn't Microsoft that invented GUI. google "History of Graphical User Interface"
I’d like to learn more about Tara
Back off - I saw her first 👺
I get the Eagles joke!
that must have changed after the actual macintosh was realeased. Or everyone would be confused.
Great wig
Actually the first spam email was sent on 1 May 1978, advertising a new DEC computer.
I programmed PDP-11 in 1990 russian clone)
Girl--> "and one time in band camp...."
Nah, McIntoshes have been cultivated since at least 1811.
seriously, windows is the best thing since the apple 2 or the IBM PC

eklipsegirl Ever heard of EDLIN? Or CP/M's ED? Line editors were the standard before WordStar.
Richard Hall OK, I get it, I actually used to edit my BASIC programs on ZX Spectrum like that.
what the...Macintosh joke!
3:09 - Quickest program load ever.
No way is the assembler that short!
So, it is a complicated typewritter?
Is it possible to purchase a pdp11?
You wish they are gold dust these days
I get frustrated in the time it takes me to type "make"; I think I'd explode if I had to develop code in this way!!
We played Diablo 2 on this, course we had to chop down half the amazon rain forest to make the paper required to load the program.
lulz
Play the song properly, dammit !!
This is worse then waterboarding.. - or not.. you decide..
papertape.. so lucky i passed that.. but hey, i know 5.25" :D
Man, how did unix even work on such a machine? Blows my mind.
This can't be authentic, there's a girl in this video.
Even BillGates doesn't know how to use this machine..
tara will you date me?
Get lost fool. I call dibs
Cool.
Someone should do a GNU/Linux port.
