Working on 68000 Single Board Computer.
Made a clock circuit and busy designing a power-on-reset schematic. I’ve made one before, but this circuit needs RESET and HALT being pulled low.
The 68000 being 24 bit address and 16 bit data needs 2x 8-bit roms and 2x 8 bit ram, but i didn’t have the components yet in this picture.
Address decoder using ATF22V10C is also halfway.
Schematics online soon.
Started a protected Git repo for C64 demo and proof of concepts for our old ICECREW group.
Installed Gitea, behind a reverse proxy.

My Sidplayer as an option to select own collection.
And I’ve made a top list

Investigating syncing effect to Sid music.
I got a great tip from Youth who made the Freakandel demo presented at X2024.
> Setup the loop to play the music > Copy part of the memory to the screen ($0400) in the same loop to look for memory locations that are used as variables for the music. > Looking at > Memory where the music is stored > Zeropage ($00-$ff) > See if there's some useful changes that coincide with for example drums > For my own tunes, I use a music routine where I can put event markers in the music itself and react to those from the code. That's >how I synced https://www.micheldebree.nl/posts/big_angry_sprite/ > You could also try reading the SID registers for voice 3 (waveform and ADSR), those are the only ones that are not write-only. > Obviously you can then only react to those changes in voice 3.
I used retrodebugger to see which bytes are changing.
Then I wrote a program which changes the background colour to this value.
I also made a program to use a joystick to see which address have the most interesting effect.
