Great pics, it seems like you took your time and enjoyed the experience. When I built mine I had a horrible dose of the Flu and I tried to rip through it in a couple of hours, it ended up taking about 3 hours, somehow miraculously worked first power up and then sidelined me in bed for the next 48 ho...

Mine arrived just before Christmas and I had it up and running pretty quickly, here's a video of it in action.

Apologies for the shaky cam, but my phones' cameras have crapped themselves and the tablet's motion camera is so much clearer than it's still camera :/

I was inspired by all the clocks being posted, so I thought I'd add my own to this thread; the timing code for this clock also originated from this thread. https://streamable.com/285jt 'Keeping time using the '59.98 Hz frame counter const TICKS = 60 const SECSX = &h60A0 const SECSY = &h61A0 const MI...

Very The Fast and the Furious, I love it.

Seasons greetings everyone. https://streamable.com/5ds9d The slightly modified code for the compiler, (the midi track was auto generated by gtmidi ) : 'Falling snow flakes 'N must be 6*n+1 or 6*n-1 const N=127 10 dim X(N)=0 : dim Y(N)=0 20 C=63 : D=16 : I=1 : J=0 : W=159 30 poke 162,D : cls 40 poke ...

The vector can also come from outside zero page. We still have 3 unused bytes in page 1 at $1f6..$1f8. Alternatively, we can simply jump to a fixed address. Except I like to have a mechanism that switches this off completely (I think...), so some variable will be needed. A single bit will do. Of co...

Because of the instruction pipelining, (there's a good explanation of how it works here https://gigatron.io/media/gigatron-hackerhotel.pdf), there is always a branch delay slot following every branch in native code. In simpler terms; every instruction following a branch is always executed, (even if ...

Whilst finishing this BASIC compiler I am working on, one of the things I have been implementing is a time sliced architecture that allows a chained set of routines to run in a real time fashion. e.g. I want my audio routines, (sound and MIDI), to playback uninterrupted and at the correct tick rate ...

Awesome presentation, congratulations.

I'll tackle it this weekend, I'm about to release a beta version of my BASIC compiler in the next couple of days. P.S. I whipped up a quick breadboard version of the new circuit using my second Nano and it works great with the latest BabelFish, although it took me a couple of minutes of head scratch...
