This 65C02 computer circuit has outgrown breadboard construction. There are 5 chips on the top right almost completely hidden by bus cables. I'm not yet ready for PCB. Starting next week, I'll move this to wire wrap on a perfboard. Wire wrap supplies are ordered and on the way.

I'm up to 7 breadboards and 11 ICs. The scope shows how sloppy the clock signal gets as it goes over long wires from the oscillator to the I/O and sound chips. I've seen no functional problems at 1 MHz system clock, in spite of this.

@daremo
For a moment I thought you had 3 oscopes. I was about to express my jealousy.😃

@daremo @oranje looks like you're getting a kind of noises from these breadboards ? are your using a passive filter ? btw nice project

@castrillo Yes, I think it's a combination of noise on the breadboards and on the very long signal wires. Believe it or not, I have almost no filtering in place right now except for a couple caps on power/ground rails. When I start to move it to the wire wrapped perf board, I'll put a cap across VCC/GND for every IC.

@daremo indeed , you can get a cleaner signal 👍 I used to do the same from my projects
