Description
This board is my design for the Grant Searle 56k z80 computer. This design has been the starting point for many other SBC's and now this one!
The expansion port is now 40pin Scothern Cross compatible, see my other projects for a 4 slot backplane. You can also use the backplane created for the Southern Cross SBC.
A new jumper to disable onboard memory has been added, useful when using RomWBW on an rc2014/rcbus card.
The RTS line is now connected for hardware flow control. You may still need delays in your terminal software.
An extra power socket.
A ground plane added to reduce cross talk etc.
