I've been rewatching your old content this weekend after wondering if you'd updated your channel recently, so It's great to see you are still alive and working on interesting hardware. This new project sounds like a great step up from the previous boards. I look forward to watching follow-up videos and playing with the emulator.
There will be some interesting follow-ups I hope. The Minimal 64 will come with a very fast Python-like interpreter that can *easily* run a TETRIS game. Stay tuned!
Oh I am SOOOO excited for this! What a fun kit this will be to build and tinker with. Can't wait to dig into the schematic and theory of operation and start dreaming of ways to make a simple sound-and-joystick interface!
That'll be great! Haven't thought about sound at all. But the Minimal 64 does have an expansion port. You can hook up any device to it and have it "memory-mapped" as I've shown in my earlier videos about the Minimal UART CPU. Cheers!
Hi Jim, it actually *is* good fun programming this toy natively. I might get rid of my Windows-PC now ;-) no just kidding... I must admit the Space Invaders clone was written with the cross-assembler and emulator. But the MINIMAL 64's workflow for me is *much* more user-friendly than on a C64. Cheers!
Did you consider selling kits for purchase that contains all the parts needed to build it? Your creation deserves more attention. I am a software engineer for over 2 decades but I am a total noob when it comes to hardware and embedded systems. Would be neat if there was a kit I could purchase that contains everything I need :)
I've got all my components in hand. Now I'm holding my breath waiting for the PCB files to arrive in the GitHub repository. When can we expect to see those? Thanks!
Amazing, I wish I had that knowledge and skills! Bravo! I hope you will be written it in the history of 8bit books! ps. You should take a look at James Sharma's TTL only computer - lots of cool ideas too. But be yourself ! I like your minimalism you always have in mind.
Thanks for your kind words, man. It is really appreciated. I am aware of James' great work - he is doing quite the opposite of minimalism though :-) still great stuff :-)
Amazing! This projects has become so advanced, it may even be commercially viable... Have you considered "compressing" the simple logic chips into a CPLD? Or would it be 'cheating'? It's just an idea to keep the cost down...
@@slu467 I will look forward to you releasing the design. I’ll probably try a configuration together to my BespokeASM assembler with it like I did with your previous system.
its good to see things evolving in today`s time, where can i get more idea about the PYTHON like language. also is there a minimalistic design like this which can run C or C++ like languages
Hi, I will show more of the Python-like language MIN in the future. Actually I started development of MIN with C syntax but refrained from it since the indented code blocks of Python offer some subtle but important advantages in the implementation. Until then, I recommend watching some of my earlier videos about MIN.
I think I have a circuit for DVI worked out, for a minimal couple of colour, low res, put out on a high res, high colour count link, so it looks like a height definition signal to the display….
Hi Tom, that sounds interesting, I really appreciate every effort to sort of build upon my design and make this system more capable. *However*, this is and will always be a *minimalistic* design. It is it's core justification. If my design had color output today and I saw a way of getting rid of 4 ICs as a trade-off for that color output I'd do it immediately :-)
@@lawrencerubanka7087 You are completely mistaken. I'm talking about the subscript commas at the bottom. They're language specific to certain countries in Eastern Europe and in English they're placed at the top not the bottom. I like this channel so no I'm not kidding.
This will be awesome! I'm waiting patiently and rewatching your earlier videos. Take your time and deliver the great quality content that you always do. All the best!

I'm really looking forward to what you have done, I'm sure it will be very clever and I can steal some ideas off you ;). I've added an SSD to my TTL CPU which is a near clone of yours. I see you are still allergic to colour but that's ok, monochrome is minimal, maybe you can design a minimal colour CPU in the future.
Hi David, thanks for following my long and winded road again... well, color (colour of cause): The memory and efficiency cost is so great for *only* color to be gained. For a true bitmapped output as the Minimal 64 produces it still has not enough processing power to spare for color... and I am slowly running out of tricks...
@@slu467 Thank you, mine isn't really very "personal" as it's the size of a large picture you'd hang on a wall. I'm really enjoying the TTL processor thing, I'm thinking of my next processor already.
@@PaulasTechStuff yep, there is always this next little idea... I've just started a side project of pushing my CPU from 8MHz to (in theory) 15MHz (still with 74HCxx logic). We'll see how that plays out 🙂
I love the "Minimal" animal logo... excellent visual pun.
Yeah, it had to be "something with cats..." ;-)

That's amazing! I look forward to seeing more. I was wondering what you've been up to.
Year, it just took it's time ;-) ... and it's only a fun project... although it *is* getting a bit out of hand.
Very cool! I had it in my mind to build one of your Minimal UART computers at some point, and this looks like a great continuation of that project. 🙂

Wow, fantastic. I would love to try it.
Thanks for Sharing
Cheers!!
It's a pity that there is no sound output😅
Missing an expansion bus? Then adding a sound module is very troublesome.
An expansion port is of cause included (see left upper corner of PCB).
This is just wonderfull❤… i wish i could make one.. thanks for the video i’m going to watch the rest of your video..
This is quite extraordinary, particularly all the work on software utilities and games. I take my hat off, sir.
Thanks, glad you like it. But this my old design. There is a new one out now with twice the computational power called Minimal 64x4.
@@slu467 Yes, I know. I'm catching up with your work a step at a time :-)

This will be released with my next video...🙂

Did you change the architecture of breadboard MIN or just routed a PCB?
The Prototype and PCB represent the very same schematic (except for the expansion port pin header).
@@slu467 You was able to put the whole th-cam.com/video/KBO1bHh34Vo/w-d-xo.html expansion board into this motherboard?

Please stop using those comma quote things, great upload but you might put a few viewers off with them.
Oh brother, you've got to be kidding. FYI, the rest of the world uses inverted commas.

It has this 'hard to define' vibe delivered by the 80s home computers. It's pure magic. Einfach gigantisch, der Minimal!
Glad you like it ;-) Danke!
I had been planning to start a project EXACTLY on this for the past few months haha. Odd and super cool to see someone having done it already.
This will be awesome! I'm waiting patiently and rewatching your earlier videos. Take your time and deliver the great quality content that you always do. All the best!
Thanks, Lawrence, it's really appreciated 🙂
impressed
Amazing, great project. Good job!
thats a pretty cool idea, i kinda want to get into interpreter integration with LUA now and making a home computer around it sounds like a banger idea
What is its power consumption?
Power consumption is 200mA @ 5.5V (1.1W).
This is a really cool project! Also, speaking of TTL computers, there is one more called "Gigatron" that the 8-bit guy also reviewed.
But I like this "minimal" approach
Hi I am aware of the Gigatron. However, it's design does not take a "simple as possible" approach...
WOW - thats looks cool for this count of "simple" chips! Cant wait to get the emulator ;)
Well some consider FLASH ICs as cheating since they weren't available in the 80s. But as I said its a "modern" home computer 🙂

@@slu467 consider moving to 74AS, you can get a 4-5x speed increase with that family compared to 74HC for a little increase in price
Where can we get the pcb/BOM/etc to build one?
Slowly coming step by step... took me 8 months just to get to this video :-)
@@slu467 That would be really great ! Can't wait for it...
Congratulations, that's a great system!
Thanks, Paula :-) but the CPU you build is also getting more and more powerful! This TTL stuff is getting kind of addictive, doesn't it?
