featuring 8 registers

reg0 - accumulator

1,2 - work registers

3,4 - jump address and condition

5-6 output registers

7 - memory address register

this program does not use any memory (which i have yet to implement the microcode to)

the max memory size is 256 bytes, i am using a CPU with 16 to help with performance.

It runs roughly at 2kHz.

it uses the lower 8 bits of rom as instruction, and upper 8 as immediate data.

it currently does not feature any inputs.

EDIT:

with absolutely 0 RAM, including the memory address register removed, I more then doubled the performance to around 5kHz!

A year ago, I stumbled upon a tutorial on yt about building an 8-bit breadboard computer and was deeply fascinated by how computers operate fundamentally. From building an 8-bit breadboard computer to a 6502 computer on a PCB, it was a mixture of frustration and enjoyment, but in the end, it was all worth it once u get them up and running.

Anyway, I just learned PCB design recently and managed to get the 6502 computer running on my PCB on the first try. I even made some electronic music using the VIA timers. u can listen to by clicking the links below:

i can provide more details if need be. The EEPROM is AT28C256.

AUDIO explains what im doing

I am trying to do it much like he does in this video: https://www.youtube.com/watch?v=BA12Z7gQ4P0

seemingly the EEPROM that comes with the kit doesn't have a maximum write pulse time, so im just controlling that with a button. Its possible im just not sending any sort of write pulse idk.

Steps:
Set output enable to high (deactivated)

Connect data bits to low/high

Press button to send write pulse

disconnect data bits from low/high

Set output enable to (active) low

See that the lights are still all on, instead of displaying the on/off pattern that was supposed to be programmed in.

I didn't get the EEPROM programmer yet because I thought i could maybe just use an Arduino for now, but i can't even get it to work manually
