That's very interesting, I'd have never thought the harmonics could cause problems, except with big broadcast transmitters designed to put out RF. Companies actually sending people out to mod electronics if they have issues is just plain cool. Bet it wasn't cheap for them to do either. You don't see that kind of attention to detail from many places anymore, except in certain markets. Didn't know CG used to have a slightly different meaning. Honestly, the whole harmonics thing you mentioned makes me wonder if I'm causing anyone trouble. I do a lot of electronics experimentation and I have yet to ever shield a circuit, no metal housings (too expensive). I generally use astable multivibrators and opamps feedback loops to generate signals, and lots of the digital and analog circuitry I make runs between 8 and 30MHz. I don't have a spectrum analyzer, but I do have a RTL2832 USB SDR, which is very sensitive. Think I should go and sweep a decent sized antenna around my projects and check for emissions?

If you're only using a couple of your projects at a time, I wouldn't worry about interference. We had a hundred units and they each had several big boards which ran at 13.5 Mhz (or 27Mhz)

Chris W Ah, ok. Makes sense, it was a matter of how many, not just one or two in your case then. Guess I'l just make sure not to run too many at a time then. And if I ever run a larger or more complex setup then I'l prepare to do a bit of testing. Can't hurt to be cautious if I make something larger. Thanks for the info.

I used to work for Waldorf Electronic GmbH, a developer of highend synthesizers, in Waldorf, Germany which is just a small village of like 1500 souls. Our group's office was on first floor of a residential building; the ground floor was occupied by a shoe shop. One day the door bell rang and I went downstairs to open the door. Somebody flashed some sort of ID at me and waiving something that looked like a big pistil-sized toy crossbow in the other hand he ran by me upstairs straight for our ISDN router in my office. Turned out the Hercules card in that router PC (this was about in '94) which had been assembled from PC part from our trash collection was faulty and had turned into a powerful transmitter jamming the red cross at a distance of 8km (!). Our well stocked collection of random PC bits had anothergraphics card to offer so repair was a 5min job, the Rohde & Schwartz direction-finding crossbow pistol said this was good so we went for the final chapter, having a coffee with the guys. They were pretty happy to have ended in an electronics company so there was not much explaining necessary to do. Apparently occasionally some broken kit at the home of a granny is causing trouble and that's much harder to do. Another funny story fromthose days was the original board for the Waldorf Microwave which was a very successful rackmount synthesizer. It was using a 68000 microprocessor running at afair 8MHz. Back then products using RF frequencies had to be approved before they could be sold and the microwave failed becase of a sharp spike in its emissions at 2GHz. Which made the product name ironical and since then everybody in the company started giggling when the word microwave was spoken. The board was modified significantly to solve the issue oh and the product name was there first before the microwave incident :)

Lon.TV What would've been the 2001 version of this? I'd still guess a studio-quality device would be more than $10.000 by then. It'd certainly be cheaper than the 1996 device because the video resolution for tv was still the same.

It made its money back many times,. one hour of NLE editing cost a pretty penny back then

i shudder to know what people think of my still operational Amiga 1200 and 500. kids today would say, did you get out and push that to get it going? "shutup kid and go play with your fragile ipad while i use this nokia as a hammer"

First "modern" computer my family owned had a whopping 8mb of RAM, a screaming fast 100mhz Pentium processor, and ran Windows 95. The on-motherboard video card had an option to add another 1mb video ram chip in a second socket. It had an 800MB hard drive, 4x CD-Rom drive, and a 1.44mb 3.5" floppy drive. It even had PCI slots! One of them had a 56k modem in it, so it was the first computer we ever got The Internet on (AOL dial-up). Those were the bad old days. My current system makes that look like a calculator. Heck my mom's old Galaxy S3 makes it look like a calculator.

It is vintage. It's over 20 years old.

Crimson Sunrise you see I graduated high school in 1993 so if that's vintage that means I'm getting old therefore I feel terrible.

I totally agree! And filling out re-calibration dates on labels than end 2018 or even 2020 - thats not a year to me.

as in editing

ahh watched all the video, it does not work.. shame.. probably a lot of work to trouble shoot this, what an amazing machine!

i would like to see that :D hope he gets it working sometime :D

wytsfrevsf send it to dexter, he could repair it. Well he got plenty of experience from the quantel stuff, so I assume he could

Them spoilers.. :)

why would it?

Watch some more of Dave's videos, and you will understand.

Male and Female connectors of different shapes and sizes.

@@snarkylive lol

The Bright Pixel ~ I remember when hey hey it's Saturday was on like in the mornings. Gee I feel old now, late 70's , back then we only had two TV channels, GLV10 witch later become GLV8 and ABC4

Yeah, looks simple enough

can have some damage, but look how dirty and oxidated the machine was when they opened, have a high chance that it was just oxidation in the conectors (since this machine seems to have a lot of boards connected via sockets)

Other systems like the Immix Video Cube also used TMS340XX chips for CG and graphics. They were the basis of the Truvision Targa and Vista cards that did video in Avid and other systems.

It also probably does the output to video recorder and broadcast as a semi autonomous hard realtime system, something you cannot expect of a Pentium Windows 3 PC with an S3 Trio driving a PC monitor. On your PC monitor, dropped frames are OK, on the tape output they are clearly not. It will also easily do windowed compositing, colour manipulation, overlays, scaling, character generation, basically the bulk of the realtime functionality of the unit, save for 3D which is an optional extra card here.

Yes, those PCBs are work of electronic art!

Yes, and the rest of the crew who burnt out their lives on this digital equivalent of the Manhattan Project.

They were likely underpaid "salarymen" who burnt out their lives on this one.

Amiga and the Video Toaster, that was the mutts nutts, back in tye day

Yeah, but it was Quantum BigFoot HDD (not IBM) and it was in mid-to-late 90's and not in 1989...

Oh, and Dave, 99% sure that the RTC is dead, and that's why it's not booting. That is a common problem with those Dallas RTC driven computers. If you find the pinout, you can rig a battery onto it and check. I had the same problem with a P5A board I own and replacing the internal battery with a jury-rigged external button cell made it work like a charm.

"comprising a bank of Betamax decks". By definition, NOT an NLE system. What made NLE NLE was that it didn't have to scan linearly to the right place on the tape - it could random-access the video from hard drives.

Seeing that chip brought back the entire narrative arc of what it meant to see it in a system. From the early "holy crap this thing is amazing," to "hmmm... should be able to handle it," to "lol, crap," and finally "Whoa I remember that! ... scrap it."

Naah, to an Aussie that's a locked Apple iPhone or a couple of "second hand" car stereos (with those screwdriver marks on the sides). Old habits...

@KarMC: More like about 40,000GBP at the time. Probably a lot more since the UK got tricked into voting for Brexit.

Oh I am, the EU is doomed. The unelected bureaucrats are becoming increasingly power hungry and eroding more of our sovereignty, other nations will follow. I love the free movement in the EU but it's not worth trading freedom, independence and democratic power for.

@@theantipope4354 they weren't tricked, the vote was rigged.. another corruption case, the majority vote against it. why do you think its taken so long for the UK to exit the EU? , The bargaining agreement is bs excuse. The crooks just don't want to exit the EU.

greenaum You have not seen many electrolytic capacitors if that is the largest one you have ever seen. :-) You should see some of my test gear that includes the old computer grade electrolytic capacitors (think 100,000uF, or greater) that are large enough that they are physically strapped down to the chassis (not PCB mounted), or even the start and runtime capacitors used on larger single-phase induction motors which can also be quite large (though owning to their operating voltage, rather than capacitance, in that case)

Um, actually, a lot of manufacturers in the 90s painted themselves into corners by using off-the-shelf motherboards as embedded controllers. Problem was that motherboards had a product life cycle of about a year, and the following year's motherboards had a whole different mix of chips, leaving them with having to either do an end-of-life buy for the particular motherboard they bought, or having to go through months of compatibility re-engineering when they went to another supplier. I worked at a company in the mid 90s, whose whole bailiwick was building embedded PCs, and their main selling point was guaranteeing 10-year availability on their products. This was accomplished through careful selection of chips and end-of-life buys, since practically NO chips had lifetimes even close to 10 years. In this case, though, it's likely that by the time this became a problem, the whole system was obsolete anyway. I started doing NLE on a generic PC in 2001, and by that time the industry had already gone through a lot of evolution as the motherboard CPU could take on more and more of the tasks. In my case, all it took was a Radius card to handle the Firewire input, and another card (don't remember which) to handle NTSC capture where I couldn't use Firewire.

maybe

Do R/C! My guess is that the JPEG encoder is actually using it's own SCSI to interface with the device, that's why the board also needs the SCSI populated. Could it be that it needs a full SCSI bandwidth?

Ádám Elekes my thought too, lol

Yep, shielding, see the other boards...

LAN Master I think so too. Also I'd guess the jpeg encoder has it's own scsi controller. A DVCPRO50 would output 7MB/s worth of uncompressed data documentation.apple.com/en/motion/usermanual/index.html#chapter=B%26section=2%26tasks=true which almost fills up a scsi 2 bus www.tldp.org/HOWTO/SCSI-2.4-HOWTO/scsibus.html Not sure which scsi version this Win 3.1 machine supported though, the newer SCSI protocols would handle a lot more.

Well, it was your one stop shop for medium-scale production ASICs, you'll also find them on many specialized PC interface cards like GPIB controllers and so on:)

Braeden Hamson Only the digital portion of the equation gets emulated in software and hardware, unless you are actually capturing and recording to an analog format. But these days we seldom leave the digital realm as most video nowadays starts out digitally captured, recorded, edited, rendered, and then output back to digital format where it will then be played in digital format without ever seeing analog (except briefly at the end if using a VGA display).
