Any interest in the Z80 - looking at creating a breakout board?
Has anybody else seen the Perf+ 2 boards ? I have added several pictures from a 6502 computer somebody built with them. Notice, NO WIRES. Connections are made by cutting pads free from or soldering pads to
traces that all run in one direction on the top, and at 90 deg. angle on the bottom (see connection diagram pictures). I bought 5 of them for $25 when they were getting funding on Kickstarter (I have no other ties with
this product) and I've been trying to figure out what do do with them. A similar minimal Z-80 project seems like a natural.
As my projects show I make PCBs as needed.
The perf board idea is not new idea. IBM used this style PCBs of the 1980 and 90's.
I saw an arduino version that was not as cheap.
Looks like you can buy them here.

Sparkfun had these smaller versions for a while (now discontinued)
On one side only each hole connected to the one beside it.
Not quite as handy, but solved some issues.

Once one becomes very proficient with manual PCB layout - you just can't get past making your own!
Particularly for making SMD to Through Hole adapters.
I started out laying PCBs using pencil and paper.
If you want to decrease the component count for a 6502 system use a R6511AQ!
It's a 6502 microcontroller with the lot. It just needs an external ROM, crystal and a few passives for a minimal practicable system.
Very cool for the late 1980's!
