I just stumbled upon this channel. I LOVE the concept. If I'm interpreting it correctly you are going to live through each year in real time, and make videos with things you find along the way? Even if that's not the idea, I really love what you're doing here.

Okay this is cool.

I can see you used Tesla TDA3505. I still have a lot of these (and others) in old TV modules. Good work :)

I have the original software for this card on the collection DVD of the Dutch edition of the magazine, I sent you the zip file by email.

The reason your camcorder isn't showing color might be the signal level of the color burst. It's possible that the ICs on your ISA card are expecting something with a higher amplitude. There might be a way to tweak the components on the RGB to composite box to boost that. Also, you could just get a modern RGB to Composite solution and see if that works. I really like your idea of trying to get these old boards to work, it was a fun watch. That said, I think I would probably try to get the first board working 100% before trying to throw the second one into the mix. Some things I would try are getting an RGB console to record a still via the RGB inputs. A playstation or PS2 can easily output RGB.

04:51 hahaha

The most incredible part about this to me is that this guy says he can't wrap his head around object orientation... I'm not really a fan of OOP, but it's certainly the easiest to understand imo. I've never heard a dev say they can't understand it.

Any chance you can look at the Kenwood KDM-7 DTMF keypad and see if you can create the pcb for the kit or 3D print the keys ?

1353.00 for that card in 93 would be like 4000 dollars today. I remember buying an ATI full motion PCI card that popped back through my VGA card and sound card. It cost around 300.dollars So, I. Think the 1353.00 is not US dollars

Grymt jobbat!! Dessutom, koda C i DOS är inte för folk med svaga nerver. 🙂

Jaså du är Svensk! Det var som fan :D AoE-tidningarna är inte att förakta!

This is very cool.

In those days, we might have just extracted RGB from a real TV instead of building a board. Everyone had at least 2 TV's. The real cost was the test equipment. Guess it was ISA because the edge connector was cheaper than a parallel or serial cable.

ohh - I bought that magazine - the English edition - and so wanted to make this. Thank you for doing it and showing the pain I would have gone through! :D

A lot of work for less than stellar results is often frustrating. But hey you tried at least. Some result is better than no result.

Believe me, these "period-correct cheap, nasty IC sockets", are much more reliable than modern cheap round-hole type IC sockets.

I remember going through all of this in about 1997. It really was terrible until maybe 2003/4.

Love the dedication to not using any modern resources, at least as much as is actually possible... Question, though - once you saw the input stage of the RGB converter pre-splits the composite signal to an S-video one for processing anyway... why not just build that part and pipe it into the composite input of the card, at least for initial testing? It's such a simple circuit, and I've got some two-way SV/Comp converters that are basically the size of the two plugs because the electronics fit neatly inside. Also it might not have helped for the colour capture, but doesn't the NES have S-video output? (maybe RGB in Europe, even) Also videotape downconverts the colour signal to be even lower bandwidth than regular RF TV or live-modulated composite. That might be something to do with not having any colour in the captured images? Perhaps whatever signal is coming out of the camera isn't using quite the right frequency so the converter doesn't pick it up, or it's even the colour transition enhancer getting confused and cancelling it out? Or something to do with the PAL phasing, if the line lengths aren't quite right (could easily happen with slightly stretched tape or other analogue media woes). There's green and purple fringes on a lot of the edges after all, especially vertical ones or very thin horizontal, which is one of the primary colour axes for composite encoding (I think maybe what you get when both quadrature components are fully positive or negative together? You see it in corrupt digital video signals and files particularly). There's a reason professional studios always had a timebase converter in the stack. How does it look if you play the tape back on a TV, or through a VCR with an adaptor? Can you point the camera at a scene and use the live composite / Svideo (RGB??) output from it as a test? I think maybe the NES has slightly scruffy timings vs true PAL also, might work to tune a standard def channel on a digital TV box (or analogue if still available where you are), play a commercial VHS tape or allow a slight stray into modernity by using a DVD player, just for verification purposes? That would eliminate or better confirm suspicions. Also the weirdness in the capture itself... I wonder if something's just not sitting right on the board. You said the sockets were cheap and nasty, and poor seating or connections in them are the source of a lot of unhappiness when it comes to computers. Maybe try cleaning the sockets and reseating the chips one at a time and see if that improves things, like what happened with the slot itself? There was also a question in my mind over IRQ and DMA assignments ... I don't know if a card like this needs them, as you're basically always polling it via direct memory mapped register writes and reads, but maybe the lack of arbitration itself could lead to there being interference from other devices on the bus? You've got a lot of things plugged in there, and ISA isn't that fast so it might be very busy, especially with the video card and maybe hard disk controller sharing the bandwidth? Could be interfering with both the reads and the writes, even, hence pixels being jittered back and forth, and the periodic brightness glitching that doesn't look like it's either 1/10th or 1/64th of the image width. (though, the fading effect suggests more a capacitor or inductor issue... something's the wrong value or not working right, or has the wrong resistance connected with it... Also also, running a 24MHz clock on the card? Very odd choice for them to make. Doesn't match with PAL pixels or ISA bus speed, even with divisions, unless yours happens to run at a true flat 8.0MHz. Wonder if that itself could be causing phasing problems. Unless of course it's all happening in the RGB converter...)

2:43 RIFA intensifies, ewwwww! - I have to grab that and make a GIF out of it :)

I Enjoyed a lot mate, great video :) I don't know if this will interest you, but I'll take my chance: Could you make a dedicated video about Mode X? I've written a small program in C and a few lines of ASM to render non-RLE BMP files on the screen using Mode 13h. As you know, it retrieves the palette from the file, extracts the pixel data, uses a buffer, sends the palette to the port, and then transfers the pixels from the buffer via memcpy to the VGA address to instantly display the image on screen-and it works. But what really interests me is moving toward Mode X to implement side-scrolling.And honestly, I'm struggling-a lot. I'm not an expert at all, just very curious. I've understood how to activate this mode, how to use the 4 planes (16KB * 4) to display pixels via VGA address, and how to do page flipping, but I'm struggling to grasp how this mode is structured so I can adapt my BMP renderer. I want to load two images on two different pages and be able to side-scroll from one to the other. I tried modifying the viewport, but I keep seeing page 1 in a loop. I did my search to find out but most of the source codes using mode X are very advanced including sprites backgrounds wrote in multiple different files. Mode X is not easy, for me to be honest. Mode 13h is much simpler because as you know its 64,000 bytes of memory are laid out sequentially. If you could dedicate a step-by-step video to this topic, with a simple side scroll nothing else all in one file...(Mode X for dummies)you would make a stranger very happy. ^^ Thanx for reading

excited to see you install slackware, I have fond memories of learning linux with slackware, installing it from floppy disk sets on my 386 took a while but was perfectly usable afterwards.

I'm familiar with late 90s computers, since I used an old pentium 3 Win98 machine in the early 2000s as a kid. Scary to think about how this machine a few years later than 92 would be completely and utterly obsolete. The 90s must've been crazy... I still use the PC I built in 2019 and refreshed in 2023. I can't imagine a 5-6 year old machine like mine being completely obsolete.

Next up, HDMI capture on a 5150, 8088mph style

I remember reading thru electronics magazines and going, hold on, what if we stacked a couple of 386s on top of each other? Yea... I should've patented that idea(Intel Core/AMD x3D(sorta))...

Great video, like a trip back to the 90s. Btw: 15:34 you built such beautiful and elaborate PCBs, solder everything together and then bite such a hole around the Scart connector? I don't get it 😀

I'm trying to get some motivation to do something similar with a CPLD that's on a board from a E1 modem. I don't know exactly if I want to sample everything from an adc and do the magic on the cpld, or sync everything externally and only sample the actual line data (which could be only intensity, and chroma in two different adcs, or separate them inside the cpld). cool that this thing is ona a ISA card. such standard was so simple, but I think most tinkerers were afraid of developing for it. I saw some isa dev cards for you to do something with them, but not many projects on electronic magazines or similar, at least on my country

Old computers were very well documented. I built expansions cards for ZX Spectrum, MSX and IBM PC both for ISA and LPT port. I built them from various articles from magazines and when I felt comfortable enough, I made my own designs. For the software I used BASIC and Pascal.

With blackjack and what? :-)

ELFA-katalogen! Vilken nostalgikick. Jag spenderade mycket tid som barn att bläddra i den katalogen och drömma om alla coola grejor jag skulle bygga… Och coolt projekt, det närmaste jag kommer nu förtiden att koppla in grejor man bygger själv är väl en USB till UART konverterare…

What a great project! It's so cool to see what was going on in the computer world when I was a child and absolutely ignorant to all of it. Amazing job!

holy crap that old Dos text editor... brings back nightmares

Great video ...I would love to see more content on your channel

Use the Id engine please, good luck

21, He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him. 22, Judas saith unto him, not Iscariot, Lord, how is it that thou wilt manifest thyself unto us, and not unto the world? 23, Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him.

At what exact date in 1993? 🙂Slackware came out in July 93 🙂🚬

Eesh, and I thought 1998 Linux was a frustration experience

Now Linux is broken because SystemD-scrap. FreeBSD is the better choice today. It's more stable, faster and efficient.

07:10 That is a free implementation of Klotski. I played this game a lot in the 1990s on Windoze 3.11 and DOS.

I did pretty much this same SLS install on a 486 with a Tseng ET4000 just a few years ago. I used multiple MINIX partitions due to their small size and discovered that, while SLS supports extended partitions, it uses a different code for them than the version of XFDISK I had from FreeDOS, and the latter will modify things in a way that makes them unbootable. To work around the missing disk I simply copied files from a slightly newer SLS into a separate binaries directory, but I didn't find a compatible LILO, so I ended imaging SLS's boot floppy and booting the disk image via GRUB4DOS. Haven't tried TCP/IP on Linux of this era yet, however, so maybe I should.

I remember walking through my dorm building at Georgia Tech (Long Live Techwood!) and seeing somebody walking down the hall with a stack of 3.5" floppies with Slackware 0.2 on it and wondering WTF it was... This was the same guy who when he graduated later that year, had the entire Unix MAN pages printed out by the campus computer center because he had so many "bananas" (GT's computer time resource allocations) stockpiled over his time at tech and decided to do something with them before leaving... They delivered the printouts on a PALLET!

Even in the late 90s, it was a royal pain to install and use

Installing Linux today is a breeze compared to what it was 30 years ago.

This was awesome!

Ah, the "good old days"!! I first looked for "Linux" after I saw a mention of it in a tech column in Infoworld magazine. I was excited about the availability of a free C compiler. This was the first time I heard about Slackware Linux, when we were still anxiously waiting for the release of v.1.0 of the Linux kernel. I was still learning Unix on my Atari ST with shells like Gülam and MiNT. This is when I chose vi over MicroEMACS. After many years of trying various other Linux distributions, starting with Red Hat 6, I finally settled, in 2008, on Slackware Linux because it reminds me of the good old days. It's still the most unmodified, simplest, and most Unix-like Linux still active. It's also the most internally documented Linux distribution. Online support is available in the Slackware distribution forum on LinuxQuestions.org

sls was rough.. still was the start of my linux journey..

Linux used to suck. It still does too. Only difference now is that it has gained enough hardware support to suck in HDR on my desktop.

I burned some crts trying to guess the frequency. It sucked! They were expensive and often there was no fix.

Thanks for sharing. Very interesting approach especially towards problem solving. ❤

Oh, the memories...

It was a pain in the ass to mess with and clunky
