Just found your channel because I'm writing a Z80 core and am taking a look on youtube. Such cool stuff on this channel. The custom hardware videos are really neat. I'll have to make a space invaders emulator now too.

Could you make a tutorial about this ? It's interesting, but I can't understand how to implement it with this video alone

That was really interesting. I was wondering where you got all your Space Invaders information? Was it various sources, or is there a document like Chris Lamont’s PacMan one? I am currently writing a PacMan emulator in Swift, and Space Invaders will be next on my list.

I think I came to the wrong video I only needed to type connect “my macadd” after pairing

I have this same monitor XD

Didn't have the correct adapter. Thanks.

Programming a computer you made with switches, phenomenal. Thanks for sharing the derramp5113 Advent Of Computing, will have a look at them both!

This video came up on my KZbin recommendations, this is awesome!

Mpm?

Thanks for the video It was an interesting way to do this because I was trying to connect via Raspberry Pi Zero which has no USB ports without having to buy an adapter.

Thank you very much for the video. I'm working on a Z80 Single-board computer. I've got Flash, RAM, CTC and SIO here. I've been missing the crucial bit of bootloader code that would let me fetch some bytes from the serial port into RAM and execute them - and here's your video, perfectly on the topic! Now if I will be able to modify your code to suit my board and burn it into the Flash, I could get started on porting the CP/M :)

I worked in the same building as the game developers for the jupiter ace an old warehouse by Wandsworth bridge they had a 100mb hard drive the size of a fridge they were all networked to!

Worked a treat on my Samsung MC28H5125AK. Tabs that hold the bulb in place are different (like inverted rawl plugs) but everything else the same. Many thanks for the excellent video.

is it bidirectional?

Interesting to see it was Yahoo software

Able to help me? Mine stopped halfways on a print and then a red light came on. Wont start any prints now after that. Turnned it off and on and unhooked the printer as well. Goes yellow and then goes red after trying to start a print.

may i ask a question, why dont just power it up from vin? the nominal voltage is about 3.6 isnt it sufficicient even though the Vin ranged from 5v to 12v.

If you left it on for too long without moving anything you could see the marks where the bats and net and stuff were visible while you were watching TV after my dad was convinced it was going to bust our telly as we were given it he didn't decide to buy it otherwise it would have been the best thing since sliced bread! He got us a Speccy a few years after this he even got the black plastic Sinclair ZX Spectrum + upgrade cover and put the gutts of our beloved little rubber key legend in to that! Never felt the same playing manic miner and Jet set Willy without the amazing little rubber keys I'd sit for ages at programming my own games which were even better than the old Binstone contraption!😂

We had one

does it work only on Raspberry PI? I think it could work easily on a x86/x64 PC with Linux as well.

Is there any chance you will ever release or sell the source code for this project? The whole CPU in a C just fascinates me.

Can we fit LED?

Nice to see this implemented in discrete components. The pity is there is probably a microcontroller that can do it cheaper.

Excellent work! Worth a subscription all by itself.

How's it going I am trying to read a BT wireless dongle from my car through my RasPi for my Senior design project ( I have 2 wired ones as backup) can you tell exactly what you type in the commands to be able to read the port, I can barely see. Was it rf comm?

ZX81 sleeper computer first. Genius.

do you have schematics?

Nice work!

is it possible to connect Pico directly to Serial port using logic level converter?i want to send midi form pico pin 0 to serial port pin 3

nice video, thanks for showing how you do this. I don't have the patience to wait 2 weeks for delivery of the $2 boards from china, but they are probably why I don't see many doing this anymore. but i have a bunch of bare coppy boards and a big roll of uv photoresist so gonna do it this way. After failing for 2 weeks I will then get the chinese boards in the mail, so no worries. :)

I want a written composition

Thanks for this intriguing review where the 10F turn out to be more useful for remote projects than the larger capacitance ones. I searched for the "Nano" brand 10F 2.7V caps - no longer available - can you recommend another BRAND as an alternative - as so many manufacturers make these spec caps nowadays that one wonders if the performance of the "Nano" brand was a general indication of 10F vs 100F or whether it was brand specific. Thanks. PS. did you include circuit diagrams - they would be useful - presume you were using 3V solar cells?

Looks brilliant, but I couldn't find the code on your github. Is it published somewhere?

Nice, thankyou so much for your results

Nice

can it read floppy discs ?

Hi, i have trouble implementing double buffer. I am using ESP32 and TFT_eSPI libarary. Could you provide some code that uses double buffering successfully?

GOOD JOB 😁👍

hey mate this seems to work so far. Hopefully it stays thanks for the tip.

Woah, I forgotten all about that little steam engine... watching this now, I remember how pleased I was when I got to that page of the manual...and how I might be able to "show them" now that my little Jupiter Ace wasn't as awful as "they" all said it was.

Excellent video. I thought the little panel inside the oven led to the bulb. Unfortunately, that led nowhere. I had been scratching my head on what to do when my KZbin search led me here. Very explanatory and straight to the point. Thanks!

Does AY sound work?

Any more details in this project? I think is super cool

is it bi-directional?

А в чём проблема подключить микросхему SPI SRAM?

USB completely without Data would according to the specs be limited to the absolute minimum. It's just that most devices ignore those specs. So according to the specs walwarts should have data lines.

I hold that one of Nintendo's biggest innovations with the NES was the use of a shift register in the controller. Because things like the NES' use of tilemaps, sprites, etc are evolutions of things that came before. However having a bus for the controllers was brand new and forward thinking

Hello, it is possible to capture "flat audio" from an accesory output accesory connector, from a radio ?? Its mono audio and need store in wav format. My purpose is capture and store the audio, store in a SD card, and other things, like "get" some information fromm screen if the radio. Almost all videos capture audio from a MIC, but not my case. Do you use the A/D from pico ???

The Tandy 100 has an 8085 CPU, very similar to the Z80. The Amstrad runs at 4Mhz but the Tandy at 2.4Mhz, which contributes partially to the difference in speeds.

I was a test engineer with Cambridge Audio at that time. We shared a common building, once a mill right next to the river in St Ives. This was a very embarrassing time as Cambridge Audio had a good reputation as a quality HiFi amplifier and Sinclair was just cheap crap. Sounded dreadful, was unreliable and full of cheap unbranded components. Was built to a similar standard as Amstrad.
