So here is where you'll find me getting my tech fix, you'll find videos on Quantel's products, electronics, teardowns of old scientific equipment or other unusual items, geiger counters and occasionally fixing things.
Located in Manchester, United Kingdom. In my youth i would take just about everything i could find to bits, some of it went back together some didn't. I just had a intense desire to see what was inside and find out how it works.
Sadly i didn't pursue electronics and favoured computing instead, cutting my teeth on the Spectrum, Atari ST, Falcon030, TT030 and the PC too and went on to design websites in the 1990s, hand coding html and eventually web application development and also administering front and back end servers for a multinational company (now long gone!). So my understanding of electronics is at a basic hobbyist level though i love reading and learning about things i don't know.

Wow, this is bringing back memories. I would love to paint directly on those video clips like back in the day. Something I STILL CAN'T DO with Adobe! BTW, could you replace the Dylan with a striped RAID array?
Awesome
15:40 When you said the disks went bad, I was immediately thinking of the AWRE and ARRE SCSI modepage settings (bad block relocation) :) DEC also disabled this on their drives to make sure they could do the bad block handling in the OS themselves
Yes, turns out disabling bad block relocation will make the drives appear to last far longer but would fail format if you ever try to do it. Probably doesn't help that the disks in these machines would have been heavily used for 10+ years also masking the issue.
I love the "do not connect anything to the VGA port" sticker... 🤣 the reason given souds rather fishy the "do not attach mouse" sticker is also rather hilarious wouldn't the jar files be sent to the quantel ?
Keep an eye out for an update video on the Masher. We have it nearly working perfectly, now we have a Hal to try it with.
Jump cuts in the colden OOpen but leave the intro and outro unedited... what's the rattionale behind that??? Don't jump cut at all
this is not the channel you are looking for, move along... move along
the programmable devices next to the FPGA probably contains the various bitstreams to configure the FPGAs on boot
Does ist handle 4k? Does it run Doom?
With our help it can make all the graphic elements of Doom look like real life!
How is the MAME version of the paint box going ? Remember hat there was an effort to port it...yes/no ?
I am afraid it's been stalled for a couple of years now. I am still hopeful it will be finished.
@@DextersTechLab If they ever get an emulator up, that's also good "future-proofing" for preserving the accomplishments of design/engineering at good ol' Quantel. 👍
Good to see you back! I have missed the Quantel vids, and got a bit overwhelmed with all thr cool stuff going on on the Discord.
Thanks! I did wonder why we hadn't seen you!
great and detailed video mark! thanks for producing and uploading!!!
What an adventure to get it all working. And what a powerful machine.
any chance of recreating a replacement PCB and transfer all the chips on it ?
Good luck reverse engineering the 12 layer PCB!
I actually did a variant of the zuluscsi a few years back that could be built for exceptionally cheap. The bluescsi board was simple enough to be able to build without needing too many pricey parts, and I used one of the weact blackpill variants that was pin compatible enough - just one pin had to be left disconnected on one of the headers. From memory one could be built for well under $10 each plus the sd card However because it wasn't using the more advanced features that zuluscsi could do, I suspect it might not have been fast enough for your purpose
Welcome back
wouldn't the actual performance depend on the type of SD card or SSD being used ? good thing the firmware of the zulu-SCSI is opensource (GPLv3) so it can be modified to implement a simulation of the missing features were the fixes sent as a pull request ?
The maximum throughput of the ZuluSCSI is mostly dependent on the speed the RP2040 can write to the SD card, which is way below the rated speed of the SD card itself.
Congrats on your successes! I dream of a world where all mechanical HDDs can be replaced with solid state equivalent/emulators... I'm glad you're getting there!
HAL + Dylan so nice together (so glad you got a working disk array even if it's not the original Dylan unit, I felt bad when it was still erroring out at the end of that series). But what an odyssey.
When it's high processing, have you checked how many kilowatts the monster needs. Sounds like a lot of silicone sweating.. 👍👍
Yes, it's about 500 watts for HAL and Dylan at idle, but +30 watts when processing video. That's about 200 watts less than a period correct setup.
The intro is ❤🔥 , respect!!!
Maybe you could do a making-of sometime;)
@@GregorPQmaybe i find some time to do this. good thing is, i recorded everything why creating the intro.
@@studiopaeper2877 You really should. When I saw it for the first time, I asked myself: "Could he have done it with HAL? No way, this looks wayy too good to be made with this ancient tech!"
@@GregorPQ thanks. yes i was trying to create something 3d looking completely on the HAL. if you pause the intro when the DTL logo enters the screen, you can see that i just stack 20 2d layers on top of each other to create thickness.
20 spinning rust buckets working, man that's one hell of a requirement !
Woah! Shout out to Swindon! From... erm... well... Swindon, actually. ... can't help wondering if you got 'em from someone I know.
Now that the Dylan is using 16GB SDs rather than the original 1GB HDDs, does that mean it has much more capacity for video now?
Watch out for a future video 😉
@@DextersTechLab Cannot wait. Now I may not be from the Quantel era, I was very much a part of the follow-on Desktop Video era (just after the NewTek Video Toaster, more like Avid Media Composer era). And 16GB of storage, at that speed throughput. This is going to be absolutely M-A-D ‼
Wonderful to see you back! Love the new intro! Funny enough, I was thinking about you and Quantel stuff last night and wanted to ask you a question, it's a bit out of knowhere but I figured you might know or able to tell; somehow it had a Quantel feel to it, the time period seems to fit, it's from the BBC... Do you know if they used Quantel stuff in the early seasons of Red Dwarf?
Yes, Red Dwarf used a number of Quantel effects. Some shots were outsourced to post production houses who had access to the Quantel Mirage for example. There is even a reference to Quantel in dialogue from Kryten!
Good to see you back! Fascinating video.
Thank you! Good to see you still here!
wow thats mindblowing !! thanks for doing these videos! back when these where modern i was a kid using 3dstudio on ms-dos, with my 486. Systems like these paintboxes where just a unreachable dream back then.. great to finaly see them in detail now.
Thank you, i was very much the same in the early 1990s, i think that is one of the reasons i find them so amazing and need to be detailed!
Thank you for getting this monster running again and showing the work process. Fascinating to see that from a hardware perspective, so much was done with dedicated hardware while the computer itself is a comparatively modest 68k. I really like to utilitarian user interface - 3D buttons? who needs that? Back when this was state of the art and used by tv networks, I imagined such systems to be way more like high performance computer and less dedicated hardware, something like 100x 68k processors in some fancy parallel arrangement. Somehow actually really elegant to achieve this result with some fast logic and what is essentially an atari or macintosh...
Hmmm. I never thought about swapping out the SCSI disks for disk emulators and SD cards... I guess that vastly reduces the heat and the noise, let alone the power requirements.
I worked at a post house that had a Harry, Hal, Henry, Paintbox, Editbox, and a three station Domino. All Amazing products!
I worked at one that had a Carl, Darryl, Donna, Randy, and Hugh-useless pricks. We didn’t have any production systems, as such, but it was a International House of Pancakes, so probably would have been weird if it did.
Any chances of uploading any ITV Quantel Paintboxes and some Backgrounds as projects?
I eagerly await any kind of future Quantel videos. :)
Can't wait to see the new stuff. You seem to be looking better with age. Can't say the same for me.
I love that theme tune, well, sort-of... It's fallen straight out of the 1980s and accompanies your Quantel graphics perfectly.
I have had fun watching and cant wait to see what more you have ...
Good to see you back...
Love the new opening sequence.
8 months? You do look younger, could be the longer hair! Good to have you back making videos!
A Quantel update!! I'm in... [frantically hits like button and starts watching]
All you need is desolder pump
The use of SCSI for networking is a bit odd...but then there were also printers and scanners which used SCSI, and Scientific Micro Systems made mezzanine interface cards which provided ST506 hard disk and floppy interfaces over SCSI.
can you record more of the battery holder i want to see if can make one
Sorry but this video is 10 years old and i am not in contact with it's owner anymore.

Hey. Could you do a teardown of an Ohmeda Biox 3760 pulse oximeter? I have a lot of medical issues, but when I was a child in the 90s, that was the first pulse oximeter I used and while I have much higher grade monitors these days, I will never forget the Ohmeda Biox 3760, and I want to see inside! ChatGPT said there's a VFT inside of it, but ChatGPT said that the Ohmeda Biox 3700 has a VFT, but we obviously saw in your video ChatGPT was wrong.
