Next part of Pure Turing is up, this goes over the memory system is formed.

I wonder if 6522 is Turing complete? I suspect yes because the interaction between I/O and counters allows a deterministic sequence of bus cycles to perform computation.

(A schoolfriend of mine borrowed my Compukit while I was away, and wrote a monitor with a single-stepping capability which was ...

Next one is up, https://youtu.be/vkU06umK2xs
This covers the logical instructions ASL, LSR ROL and ROR

The next video is up. It is the bring-up for the 4 symbol Turing machine emulating a 6502 (rather slowly)

Given that you showed 6502 assembly for a Turing machine, I imagine it would be possible to have a 6502 emulate a 6502. Not a good idea, but certainly possible.
Yes indeed, i'm planning to do that in an upcoming video. Not practical, but it shows the idea of one machine emulating another including ...

I watched the first couple of Apple ][ videos. I really like the split-screen view where you show the schematic along-side footage of your actual working practice. I'm going to try that insulation sliding trick on my next project!
Great thanks. The trick is to pre-stretch the wire relative to the ...

This is the second part of the Pure Turing build.

I never thought of placing a wide IC over the breadboard power rail. This frees up the tie points that would have been covered by the chip, though perhaps it results in a slightly less compact layout. Unfortunately, it doesn't work with a machined socket.
It actually works surprisingly well. The ...

Hello all. I'm Matt Regan. I've made a bunch of youtube videos on the 6502, from a Turing Machine perspective.
The different playlists are at varying levels of completion, but here is a basic breakdown of what is where and the logic behind the progression

1) Apple 2 wire-by-wire build.

Cool, shall do. Thanks.

Hello all.

I'm Matt Regan. I was originally introduced to the 6502 back in the 1980s via the VIC20 and Commodore 64.
I've made quite a few videos on some TTL 6502 CPU builds. These machines are based on Turing machines and so they do not have the usual hardware you find in a 6502 such as the ...
