8-Bit Show And Tell
Канада
Добавлен 27 ноя 2018
Hi, it's Robin. I'm a programmer, collector, and all-round enthusiast of vintage computers and video games. My videos focus on what I find interesting in the realm of 8-bit (and sometimes 4 or 16-bit) computing and gaming, whether it's about easter eggs, programming, bugs, history, game development, or whatever else. I usually go very in-depth with topics because I want to understand the how and why. There's still so much to learn and explore in these old systems.
Please note: you're of course welcome to email me, but the longer and less focused your email is, the less likely I am to respond. There's many of you, but just one of me, so requests to debug your code, or teach you assembly, or to phone you because "you just have some questions" all take a lot of time and energy that should be put into making more videos, and will probably not be answered. Sorry!

Oric-1 First L̶o̶o̶k̶ Listen
We take a first (short) look at Tangerine Computer System's ORIC-1, a British-made 6502-based computer that had some, but not a lot of success in the UK and France in the early 1980s, competing primarily against the ZX Spectrum. I couldn't manage to get any video output from the computer and normally that would mean I'd just shelve the video and move on to something else. But when I was told I could blindly get the computer to make sounds through the internal speaker, I had so much fun with it that I still made this video. Sorry! At least it's short by my standards.

Best Ever VIC-20 Cart? Penultimate 2
had a ZX Spectrum. POKE 23609, 0-255 would change the keyboard click (value 1) to silent (value 0) up to a 1 second beep (255). 30 was a good length
In Europe a lot of computers had a RGB output to connect to a TV through the then mandatory SCART plug. This gave a pretty good picture, much better than what could be achieved with an RF connection
Just stumbled on this channel. I was a kid in the 80s and spent a LOT of time on the C64, but was too young and not patient enough to ever write anything other than very basic and silly programs. I did try to type in a horse racing game from Commodore Gazette once but it never worked 😅 But since those days, I’ve never really understood the LOAD command that I typed in thousands of times. This video was a real blast and I leaned something about a cherished part of my childhood. Thank you!🙏🏾
Please pop the cover off the step-up transformer and check that the live and neutral on the UK connectors aren't swapped on one of them; with the configuration they're in on your device, it is ultra tempting to just run the wires straight across from the left live to the right neutral, which can be a shocking problem.
The first home computer I ever saw at my friend's house, absolutely blew my 8 year old brain!
My parents bought the Tomy Scramble for me for Christmas of 1982. It was awesome. It actually has 5 levels. That's pretty good for a VFD game. Tomy also made a handheld version of Pac-Man but it sucked. Many people hated the Atari 2600 Pac-Man but it was better than Tomy's Pac-Man.
I like your "Telidon" button. Always wanted to play with Telidon but it was DOA.
RGB to SCART? Every RGB connector I've ever used is SCART.
The RGB output may well be at TTL levels, requiring voltage level conversion to be used with SCART. This is what those RGB-to-SCART cables tend to do. Of course, since Robin is going to feed that SCART cable into a converter to get HDMI, it should probably be noted that there is the widely known RGBtoHDMI device that uses a Raspberry Pi Zero to do a direct conversion. I imagine that a configuration for the Oric-1 is already present in the firmware for that device.
Orientation on AC doesn't matter. If you use the EU plug you can put it in, in any direction. There are other things that are more important than the orientation of the plug that you don't have in the US and Canada. Why didn't you replaced the power supply with one for 120volt?
I had a magazine with a list of pokes. Brought it to school to study them in my free time. Handed it over to a kid who asked for it. He never gave it back. Very tough lesson learned. Never entrust anyone with your poke codes.
Just wait till you discover the background and foreground colour attributes for the screen. These have to be placed (poked or plotted) on the screen and take up one 8 x 8 character location. They affect everything to the left of that location on that row or until there is a different attribute further along. Alternatively just use the colour command for a screen wide colour for text or background. Over writing attributes with on screen text can do your head in sometimes
Hi Robin, your video made be laugh today 😂 Just listening to the Oric 1, I have one here In the uk, and they're a sweet little computer.... Thank You 😊
Code golfing on a C= 64, this video is the cutest.
I LOVE MY C64❤❤❤
I REALY LOVE MY C64 ❤❤❤ FOREVER ❤❤❤❤
ZAP and EXPLODE? Robot uprising is coming!
Be careful with that voltage converter - those un-shuttered 'Death-daptor' style outlets might ZAP and EXPLODE if you catch your fingers in one...
I LOVE MY C64 ❤❤❤❤ FOREVER ❤❤❤
5:08 Those death-dapter sockets where you can stick the Earrh pin of a plug into Live don't make it look very professional.
It's a relative thing; I was comparing it to the type shown in Tech Tangents' "Making 240V AC In the USA, Interesting but Dangerous" video. That socket style is very common on all converters/adapters in North America. Not saying it's good, but that's how it's done here for whatever reason.
lol what happened to your power connector? UK plugs are supposed to have 3 prongs, not 2.
Man, that little song reminded me of the music in Tazmania on the Sega Megadrive, lol.
Later UK mains plugs banned plastic earth prongs
I was going to claim the lack of joystick ports was due to early British computers being more serious systems (not to be confused with powerful lol), then you went ahead and showed off the ZAP and EXPLODE commands and I decided, whilst that was generally true, clearly in this instance I'm completely wrong XD. Thanks! Great video, the Oric 1 seems immediately lovable as a system, though maybe its all in the telling ;). Cheers.
outro music was inspired!
Interesting! 😃
In Germany from about the 90s on every TV could also receive and display NTSC/Secam/... - Why is this different in the US?
hm, human music, I like it.
I would not have been surprised if there was a television out there somewhere that was capable of showing PAL broadcasts. Many American TV's were made in Japan (the reasonable ones) or China (made by slaves in a prison camp). In both cases at the same factories there are NTSC TV's and PAL TV's made, often the production belt has to keep on turning to make a profit. Often stuffing in the same boards to keep it simple and cheap. If it is not working on one TV try another.
I love that the RETURN key makes a deeper THUNK sound instead of a CLICK like the rest of the keys.
12:15 Crazy Bus OST
How cute!!
Connect it to a modern TV.
You know you will have to play Petscii Robots on it, there's a free version just for this system.
12:13 Cool! It's the Crazybus theme song!
Loved it! Thanks for the smiles and chuckles!
"That's not a standard cable connector" *points to an ordinary looking DIN/MIDI socket that's been around, at least aboot 50 years, or more, and still used on certain kinds of hardware. You could have probably just got one that broke out into component, composite or VGA, or whatever NTSC connection that was convenient.
Well it’s probably 15khz not 30 vga expects…and then it’s also 50hz not 60hz for vblank , so doing this might make it show something just not something usefull :)
4:3 Sharp Aquos TVs from the 2000s are great for multiformat RF and AV!
4:53 WTF are you doing, brah? Just grab any North American 9V DC power supply, and check polarity, and/or solder the connecter if needed. The ground plug is broke off that British transformer, so if it fails and mains passes to the DC side, it might light your computer or yourself up.
why not just use an adapter from your country that spits out 9 volts DC @ 300 ma ?, I mean all you are after is the DC voltages any way and that is the same no matter where you are in the world and a lot cheaper than using a voltage up step system.
Make it play random music in a particular key and add rests. More typing though, more chance of mistakes, and even something like a CPU trainer or altair would give more feedback.
The Oric, one of the many cheap colour/sound home micros that attempted to grab a piece of the pie that Sinclair was gorging on. Aside from the domestic rivals - Oric, Dragon, etc - It seemed like barely a week went by without another hastily-imported-from-somewhere micro being announced. I think I recall a Texet, a Laser 200, the CGL Sord M5, and there must have been a half dozen others I've forgotten. I seem to recall that magazine reviews of the Oric 1 highlighted unreliable tape loading as being a problem, and I don't know if it was much improved in the Oric Atmos. I also recall the magazines often showing a photo of, or mentioning the closeness of the name Oric to the advanced computer from the British TV sci-fi programme: Orac.
Orac as in Blake's Seven?
@@Metal_Maxine Yes, thanks; I clearly didn't finish my sentence off.
The forst two games are funny because you could just buy a deck of cards then deal a hand to yourself for a lot less money. But hey, toys are fun.
Reminds me of the music from Short Circuit. And now I need to find an Oric, because that is neat.
3:02 we never could use joysticks because we always have a cup of tea in one hand.
In the early 1980s I worked for a radio station in the UK that transmitted a programme about the craze that was home computing as part of its education remit. A computer review on the radio who would have thought it, a bit like a RUclips review with no video output! More often than not, the companies forgot about their machines they had sent out for review (or the company went bankrupt) so I still have an Oric-1, Atmos and a Jupiter Ace tucked away in my loft. Sadly, the only machine of that time that I did have to return was the brilliant Memotech MTX 512.
I loved my oric 1
UK TV channel 36 uses the same video carrier frequency as UHF channel 34 in North America. So with a British computer like this, if you have an old TV with manual tuning knobs and a manual vertical hold control, you should be able to tune it in on channel 34 and then adjust the V-hold knob to lock onto the 50 Hz refresh rate. It won't be in color because of the PAL encoding instead of NTSC, but at least you'd be able to see it in black & white. But newer TVs and VCRs with electronic tuners will just skip over the "foreign" signal on that channel, and even if you could get the TV to display it, the picture would be constantly rolling due to the lack of a manual V-hold adjustment.
I would never have expected to take a video in this direction, but you absolutely made it work. That was fun. Can't wait to see it in all it's video glory. ;)
But isn't a RGB signal a direct video signal, and not a RF signal? As in, couldn't you feed some monitor with it, like a 1084? May need a custom soldered cable though. Same goes for SCART btw.
🤣
