    I had to take two assembly language courses to get my BS in Computer and Information Sciences. The first was assembly language for the IBM mainframe computers. The second was for the PDP-11 (I still have the textbook.) Assembly language for the PDP-11 was very different than for IBM and at first very confusing. Once I got the hang of all the different addressing modes, it seemed easier, very flexible and I enjoyed it. The IBM assembly language seemed primitive in comparison.

  • @Alpha8713

    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.

    Cheezy, but fun! I'm old enough that I actually lived through that era, though thankfully near the end of it when CRTs and hard drives and timeshare operating systems were becoming more widely used. My very first program, in 1977, was written on a Varian 620f, which had a hard drive, so all you needed to toggle in was the hard drive boot program, then run the editor on the TTY, enter the assembler mnemonics, save to disk, then run the assembler (debug, rinse, repeat), then run the resulting program. Hello world was very popular then too LOL! When I graduated to bigger systems, we got to punch our programs on 80 column cards, then transfer them to magnetic tape, then run the assembler, etc, etc, still outputting to TTY. A few years later, we were programming on PDP-11/44 running RSTS/E, with one computer (the size of a room!) supporting 20 programmers with a whopping 256K of RAM and a 480MB hard drive which I'm sure the whole system cost well over $100K (in 1985 dollars), but at least we got to use DEC VT102 (80x25 CRT) monitors... sweet! Ah, memories...

    This video definitely served it's purpose of introducing the PDP. I'm working on building a clone of the Altair 8800, and am always interested in the 70's technology. Thank you for making the video. Could you share a link to watch the fifteen minute show? I believe this show had some of the same actors, directors, etc, but I haven't been able to find it.

    I remember back when I bought my first PC in 1987 (a 80386), I went with a 40MB hard drive (Seagate ST-4051) and a buddy who was a PDP-11 programmer and operator told me I was wasting my money to buy a drive that big that I would never fill it up. I still have that hard drive and now wonder if I will ever be able to see what's on that drive.

    I was to the marketing guy for the 11/10 which was exactly like the 11/05 except for one thing, the bezel. The 11/05 was originally targeted for the Orginal Equipment Market, OEM and the margins were very low. The marketing and sales cost for the end-user market was much greater so we need more money for the computer. There we created another model for that market. As I remember it was $500 more. I also had to explain the difference between the 11/05 and 11/10. Never lied just told the truth. The only time a program was toggled in was to run a loader for paper tape input or some other device. The teletype was the cheapest loader and was very slow. Its speed was 110 baud.

    The inside of such computer has lots of cooling fans, which can get pretty dirty. So in manufacturing areas we had to do maintenance monthly, take it all apart and clean all circuit boards and cooling fans to avoid overheating. It was a real dirty job for a Rookie technician.

  • @b.baggins8893
    @b.baggins8893 3 ปีที่แล้ว

    Being a DEC technician we used the console to toggle in minimal code like to print letter a to the attached printer. That told us that Cpu and memory is basically working. Typical repair time about under 15 min. To repair disk drives and tape recorders takes longer. Memory boards been pretty expensive in the days. A car crashed into my trunk and damaged my spare part containers. 90% of the total damage was on my parts, 10% on my car.

      I hope your parts are better now. I had 3 cracked ferrite beads in the core memory. The DEC quote was outrageous. A third party guy rethreaded them for 300 pounds Did you about the memory overheating test program? It worked, so was withdrawn.
