This project is designed to be an easy build Z80 system.
The idea is that you can build the board without even fitting those tedious RC2014 sockets, then test it with the simple bit-bang serial port. That's 5 chips + oscillator + 6 pin header + a few Rs and Cs + LED + reset button. Looks like this takes about 175 solder joints. Sounds a lot, but way fewer than typical RC2014. Should be a good cha...
Banked EPROM RAM Board
- EPROM can be enabled/disabled with write to register
- EPROM occupies first 16K of address space
- First or Second bank of 16K in EPROM can be selected
- Modified to use ZIFF Socket
