Initially, I wasn't sure which one to choose, but I ended up buying a Commodore 64 Ultimate Starlight Edition.

Here's something interesting about the Z80 NOP Tester:

Once we reach address A7, from A7 and beyond, their LEDs flash twice as fast as the A0–A6 LEDs.
This is because of the refresh cycles. (Cont.)

You'll also find a potentiometer at the bottom right corner that allows you to adjust the clock frequency from around 4 Hz to 90 Hz.

I also added LEDs for the clock and other control signals, such as M1, RFSH, MREQ, and RD, which I think are really useful.

When designing my Z80 NOP Tester, I thought, "Why limit it to just the first eight address lines?" So, I added LEDs for all sixteen address outputs.

A breadboard is good for a first prototype, but a custom #PCB is much better. πŸ˜ƒ
What do you think about my #Z80 NOP Tester?
I think my new #oscilloscope has arrived 😁
I built a circuit for a #Z80 NOP tester using a few components I had lying around on a breadboard, and it appears to be functioning properly!
