  • Dave goes back 20 years and find an old PC Based Logic Analyser project of his that was published in Electronics Australia magazine back in 1996. He uncovers the original timing diagrams, schematics, and prototype. And tries to resurrect the old Borland Pascal 7 source code and Lattice ispLSI PLD chip code.
    And the old Protel Autotrax for DOS PCB and schematic files.
    Will it all work 20 years later?
    A bonus side detour into the venerable Tektronix TDS210 TDS220 oscilloscope, the first review!

    Oh, man, does that bring back memories. When I was a freshly minted embedded real-time software engineer in the mid '80's I was immediately tasked with programming all the GALs and PALs (using PALASM), since that "felt like software" to the old-school EEs (who were still transitioning to PC-based schematic capture). But that work sharpened my digital hardware skills, and got me deeply invested in moving functionality back and forth across the hardware/software divide, to get the most done with the smallest board and the least power consumption. Now we live in a wonderland for embedded design that ranges from discrete jelly-bean logic, to immense FPGAs, to low-power multi-core SoCs that include a shocking number of peripherals and application-programmable GPUs. Whew, what a ride!

      Stefan A It's one of the many benefits of exercise, staying aggressively active and fit. I'm 58 and look nowhere close to it. Some part of it has to be genetics (my dad still looks great in his 80's), and another part has to be avoiding stupid eating (easy on the carbs, avoid processed food), but the rest is absolutely dominated by the contribution of staying fit. It was a chore for me until I started triathlon, now it is a joy that defines my lifestyle.

    This video brings back some memories. Back in 1979 (or was it '78) I designed my own 100 channel data acquisition device. It had a trigger level and if any channel triggered all channels were fed into a commodore Pet computer. I used a 6502 microprocessor and a couple of PIAS. The whole mess was wire wrapped and on several cards in a rack card cage. I was in the last few years of a BSEE degree at the time. I finally graduated in 1980 after taking a final 400 level math course.
    Anyway, I entered it in the IEEE student paper contest and won third place. Thanks for all your great videos. I have been a code monkey for the last 30 years but miss the lab with scopes and spectrum analysers, etc...

    Even as advanced as electronics have reached in scale today, the fundamentals remain valid. When my grandfather past away, his books on electronics were passed on to me and some of them dated back to 1948. In fact, he had a book that gleamed the Wheatstone bridge circuit as the latest Apple product!, but this circuit is still used today and has gone from dollars to pennies to make now.

    When Dave is sleeping, his supercap is c­harging, when it is fully charged and dr­iving the base current of the transistor­, he wakes up in the morning......he sta­rts to work.......the lunch is acting l­ike a resistor and he feels like eating is resisting him from wo­rking and he is desperate to go back to the bench.......I mean Dave, you sleep elect­ronics, eat electronics, you work elect­ronics.....love you man! Oh the good old DOS days......everything you say make me nostalgic, really! We learned everything/electronics the hard way.......rather the fun way.......I wonder if I can make one of my son (yes, I'm blessed with two, first one- double the age of Sagan and second one half his age) get into electronics, I try to show him your videos and blogs, how enthusiastic one can be about electronics, how much you can be in love with these things and stuff like that! Electronics is fading away now a days.......anyways....really love your passion and knowledge. Keep going......keep up the porns for us.......

    Looking at computer stuff before my era is quite fascinating to me. The fact we went from having to model things like this on paper 20 years ago to simulating everything inside a program inside a true UI is amazing. My father gave me a "Computer Shopper" catalog from September 1991 and looking at it is quite simply fascinating and the fact the stuff we have today is something people 20-25+ years ago could never have imagined working. "You'll never carry around a calculator with you all the time" is a popular line from my elementary school teachers, but we have so much more. I carry around a 5.5" 1080p phone with a 2.5 GHz quad core processor and 3 gigs of ram with 16 GB memory and 4k video camera. That is simply unimaginable just two decades ago.

    The old Turbo/Borland Pascal bug which you hit is where the runtime library does a quick timing test to calibrate the Delay procedure... It counted how many times it looped in 1/18.2 seconds and computers faster than around 400MHz actually hit this bug.

    Hi Dave! I definitely agree with you! I am only 16 but I can tell you that you do learn a whole lot more when something goes wrong! I originally was just doing the raspberry pi and arduino thing until I realized that when something did not work, I had absolutely no clue how to troubleshoot it and figure out the source of the problem. I then started learning my basic electronics skills, heck I even went so far as to buy a copy of The Art of Electronics and read it from cover to cover. Anyways, thanks for all the awesome, informative and entertaining electronics videos!
    Keep up the good work!

    Nice one for 747 ;) I´m still using Protel ´99 on a Win98SE machine for my hobby electronics..... I´m pretty fast with it, due to my special 4 axis input decive (a mouse with a trackball on top), so i can navigate cursor and sheet independently; never change a running system :)
    I hate BP V7.0 for this bug!, and never use these "StarterKits" again, as it all depends on the software, when the software refuses to load, you won´t be able to use the hardware....
    Long time ago i bought a Motorola DSP EVM56k board, it was great but the software runns in DOS native only (no dosbox!) up to 5.x so you would need an old PC just for this board;) it was also very famous that days, even prof. synthesizers uses these boards...

  • @teknifix
    @teknifix Год назад

    I realize that this is an old video but I still write in Borland TP7.0. Even if you put the graph unit and the others in there the resulting compiled program would fail with runtime error 200. The CRT unit wasn't coded with the realization that computers would exceed 200MHz and the initialization code for the delay procedure would fail.
    TP7 still works great if you create or find a CRT unit replacement.

    BTW, the Borland CPU speed bug patch is a hot patch. You don't need to recompile the code, you just run the patch. The bug was in the start up code and is/was in a known area of the EXE file. I still have a copy of it just in case I have to reinstall some old Borland based tool. My old DOS cross compilers run just fine id DOSBox.

    I'm really good on archiving ancient stuff and sort of bulk indexing it. Some of my -Rs cds are turning yellow. I combined a lot of these CD-Rs into DVD-Rs and saved space when I did it. I don't care about the totally obsolete Linux versions going yellow though. Some stuff I am NEVER going to use like Red Hat 3 or slackware or like 1994 Corel draw or something, so I don't know why I keep it. One pretty cool program came with like a Sound Galaxy card, voyetra midi studio or something. When I got to win7 none of it descendants would work, so I found a Japanese program that does the same things mostly. Also I use 'kxproject' for my Audigy2, and the synth implementation does not work properly in win7, so I got some sort of soft synth with loadable soundfonts to mimic the former ability. The kx days are ending because the end of the emu 10k chips, but I have like sound dsp flowchart conifgs for different things I am using my computer for. Very nice to use...

    bigger screen, bigger resolution, gridlines, true color, hardware accelerated line drawing, infinity part database, auto-routing, two side PCB support, quick analog and digital simulation :)))

    I use 5mm grid paper when laying out circuits for pad or stripboard, there's not that many tools for that on the market (or free for that matter), and it sometimes happen I go the TeukkaEDA(tm) route for very simple designs or ideas. A stack of gridded (and lined and blank) notepads is always useful.
    So, Davealyzer Mk I design notes ? *continues to watch*

    Heck, we used these TDS 220s in EE lab... a few years ago. Poland, so backwards.
    You seem to love the word "basically" Dave. It's anything but basic - pretty good design. You could replace these 72ACs with modern equivalents to solve the issue. And of course replace the CPLDs with modern small FPGAs. You can still do it the old schematic way, I've experimented with that in Xilinx and Altera tools - it still works.
    Why would you compile it in original Turbo Pascal when there's Free Pascal and is 100% compatible? :)

    Cool, I'm already printing the schematics!!! Any plans of a new version with CPLDs or FPGAs??
    Question they still use Delphi at Altium? By the way in Brazil people, still use delphi a lot :P

    Haha, great video dave! what i find funny is when you say borland pascal, it sounds like youre saying ball-end pascal, and i was just like, who names something ball-end?! XD

    OOPS! EEVblog looks like you are pointing to the input buffers but are actually talking about the SRAM at 21:17 to 21:50. Gotcha! ;-)

    Used Protel at Practel electronics. Did you ever write programs to auto generate changes to text file pcb file. For like generating Buses or large Memory layout. Before Autotrax and was faster than autotrax for repeated layouts

    Omgwtflol?! I've just spent the last hour or so trying to figure out if I should spend $20 on the (discontinued) USBee AX for access to their PC suite or attempt soldering SMD's with JYT Tech's 1-Ch 200khz DSO138 DiY Kit for access to a nice TFT and Arm development board? And then I see the title on this EEVBlog, uploaded just a few hours ago...Exactly what I've been trying to understand about the USBee is the PC Based Logic Analyzer advantage and weather it grants access to an Oscilloscope portion of the software or not? 😟

    ispLSI were discontinued? Damnit.. I've still got a few dozen of those around and planned to use them in an upcoming project. Any hints whether the programming software which supports that series can still be obtained?

    "Who knows, the way things are going, TV and VCR service manuals of the future may have logic diagrams instead of CRO shots..." - Dave, you also predicted something in your article:D By the way Borland's GRAPH.TPU graphics library had absolutely terrible performance so I wonder why Protel used it in their software. My only guess is that it was easy to cater to most graphic cards because of these BGI driver files instead of doing it efficient way by writing straight to graphics memory (0x2000 segment or something?). Still I remember that after trying to do any decent graphics with that module I ended up writing assembler routines because responsiveness of interface was worse than damn Tektronix 4014 vector storage tube display...
