The audio in this video is a little soft, so be grateful for small mercies. I have been working on a secret project, which is to put the ZX Spectrum BEEP code into ROM for the #RC2014 Orton 3C. By coincidence, I found that I was using a tune from Star Wars on the day before Star Wars Day and so I went for it today and made a complete medley.
(Yes my Orton 3C is fitted with the 3C-PO shim...)
I wrote my first blog post about this before I'd added the ROM, so it was a pretty pure 3-chip 'all code and data toggled in' project at that point.
I couldn't have done this today without using the ROM though!

@shieladixon@oldbytes.space That is fabulous. I also saw the Happy Little Diodes video and thought about doing something like this, but never took it further. If you've not seen it already, Ben Eater did a great video on creating sound for his 6502 breadboard computer.

@shieladixon I love the fact that the Z80 was released in 1976, so George Lucas could have genuinely used 3 chips to make this tune for the movie in 1977!

@shieladixon My kitty is fascinated by your Orton 3C music :)
