Early reZet80 history - stage 2

This time I moved to bigger PCBs.

I used a ZIF socket in order to use both NMOS and CMOS CPUs.

I sticked to the nonvolatile SRAM chip and managed to keep my program alive in the RAM.

I also sticked to the single stepper and blinkenlights.

But I controlled all data, address and control lines via DIP switches.

I introduced the reZet80 bus.

And my power supply for 5V and 3.3V got an update.

Soldering didn't get much easier even with bigger sized PCBs.
