I'm calling bullshit on the 14x speedup of the graphics capability. I stopped watching as soon as I saw that. If you're not willing to show what the actual experience of using this computer was like, don't bother with making a video about it🙄
"Infamous" VIC and SID? Why?
Interesting mod, though not something I'd have bought back in the day.
I just picked one of these up the other day. I may have to do the power cord mos, that would make it a lot nicer
This is a link to the sockets I used. amzn.eu/d/dlikieH
Those games are a bit disappointing, the video-chip inside this computer is the same as in the MSX-1. So, 15 colours and transparent that happens to be just as black as black, and a resolution that was fine for the eighties. I saw better games on the MSX than on the Texas Instruments 99/4A. My impression is that whey did not even try to make something really good. Even the ZX Spectrum performed better and that computer did not even have a real video-chip!
Nice pink dong
Just saying hi. Met you at ZZap Live, you may remember we chatted about the ZX81 workstation. I've subscribed now, looking forward to watch some vids :)
Would u like a neoGS?
I’m OK. Thank you anyway 👍

2 month ago I bought mine, thanks to your movie I can consult if maybe something is missing in the kit!
computer what needs second chance <3
You spoiled that nice computer... power supply thing, that terrible fdd and terrible "white" 3d thing... I am now at the half of the video and this kind of nice computer need to treated better. you made a diffrent computer. this is not "retro" anymore...
Great video, but where is the true hires (you needed modified RAM-pack or in 1K play my 1K hires games of which you had one in screen for a moment). And since may 2024 I discovered a new displaymethod which I call "quaracterdisplay". You can swap characters before the current character is drawn. So with 4 lines of the 8, 2 lines of the I and 2 lines of a D you get a key displayed.
@@johankoelman2996 I had to stop somewhere 🤔
what a strong case! great review, thanks.
This was even worse than the Intellivision ECS computer, the graphics were far worse, not even real graphics, just ASCII charters and it was not even a real computer, far worse than any other computer out during it's time, the VIC 20 was better, the controllers were worse than the Intellivision 2 controllers because they had key pad with only 6 buttons and no action buttons.
So why not repair the non-working 16K RAM pack? And can the ZX81 be upgraded to 64k?
Hi Everyone. This time Retro Relix reviews the 1981 Sinclair ZX81, we complete an existing project and review some of the remarkable features from this little retro gem. Enjoy, Mark.
the sam coupe psu and rf box is identical to the amstrad one
You are to kind to this monstrosity case xD
The games look like zx spectrum ports.
Your keyboard membrane died during the production of the video xD
Building further upon the basics of the ZX Spectrum is voluntarily limiting yourself. I understand that they wanted to improve the ZX Spectrum with a better keyboard and something better then a cassette player and that they aimed at the ZX Spectrum user. I like some ideas, the buses to expand the computer, the six channel sound etc.
Congrats on your find! So nice to see such a rare item.
Thanks ! Nice video.
I really wanted one of these at the time. Nice system, but the market was way overcrowded by the time it came out.
euro connectors, they work great when soldered to a board, but my god I have banned them from being used when connected to a cable, they are more fragile than a dried egg shell
This is pretty cool. They should have made the case black instead of white/beige.
Floppy drive doesn't have network controller that's the midi ports back machine
Mode 2 has 6kb pixels then a 2kb gap and then the 6kb attributes
dis is fucking hot, except the old powersupply, good that it is changed
> Where’s Miles? I think we moved on from miles to metres a long time ago.
Romove the cardboard shield it is trapping the heat. Surprisingly it does not have a exhaust fan with two old 1541s and a C64 motherboard generating all that heat, it won't be good for long-term use.
look like the MSX he suffer from poor spectrum port with low res graphics and bad sound, far beyon its possibilities.
This was several years too late. At that time I was about to buy an Atari STE. But at least now we have the Spectrum Next as the logical continuation of the original ZX Spectrum.
It a lot like early Amiga software
got 2 of them in my collection
A totaly june if you can't be productive and only play...on dat... Wtf for upgrade? . For games.. ?...a junk...just drop him in garbage recycle shit
15:27 Marek Biliński "Dom w dolinie mgieł"
The Lyra 3 demo 👍
I recall a mod at a user group meeting that seemed to double the speed. Anyone know anything about such a mod? The guy added a small board with some chips and jumper wires.
I live in Poland and in 1988 I bought an Atari 65XE with an XC12 tape recorder. In 1990 I already had an Amiga 500, so I didn't buy SAM Coupé. If it had appeared a few years earlier, it would have probably been a success, and in 1989 16-bit computers were already king.🎮🎮🕹🕹
I had the MGT 3.5in floppy for my speccy, excellent bit of kit. I lusted after the SAM Coupe, but by the time it was actually available (and I could afford it), the Amiga 500 was just a better option.
I love the design.
I saw this at a ZX Microfair and talked to either Miles or Gordon. Forgot which but he was very approachable and happy to chat. Very cool machine.
Did you daisy-chain the drives internally? The last shot of the back of your setup suggests so (as there are no serial/disk drive cables visible from the outside).
Hi, That last shot was meant to demonstrate the Dymo labels without the clutter of cables - so still externally daisy chained 👍
i think put a pi4 in there give it some turbo.
My first ever home computer! Takes me back.
Ahhhh! ... Wait, Sam Coupe. . . Brain recall says yes it existed, but no one outside of the press said anything about it. 80's flashback over. Amazing video, cannot believe how simple the mainboard layout is for this system. Know very little about it, shame it was not more widely known. Looks like an excellent system, with the obligatory odd keyboard layout especially on that righthand side. Looks intriguing.
Lack of hardware graphics acceleration meant it was never gonna be taken seriously in 1989. Single and flip screen games were pretty passe by this point, and "smooth scrolling" like a Spectrum game would get you laughed out of the room. Most kids would've rather opted for the cost reduced C64 because they'd take proper smooth scrolling over screen tearing and 8 pixels at a time or low framerate, which would be regarded as pure jank. That's if they didn't opt for a Sega Master System.
