Z180 "Brains" system Board-1
I have been working on this for some years, This is the first in a set of boards that i hope to add on and make a Vintage Z80 set of 3 systems .
all the systems run very similar hardware so i think this may just work out. but you can use this as a starting point to make your own Z80/Z180 system board.
The Main board i have labeled as the "Brains" board-1 and holds the Power unit 5v dc to 3.3v, The PLLC socket for a CPU i chose the 10Mhz version of the Z180.
It has 512Kb of S-Ram and also the Breakout Header for the next board or your own Breakout board, as all signals are on the header pins. There is also a small connector for a PI or Programmer to put data into the board if needed.
There is an option to power the board from a 3.3v on the small header if using a PI but do not run Power from both connections... YOU HAVE BEEN WARNED !!!
So i hope this will help a few people looking at building there own Z80/Z180 PC system. please keep an eye out form more updates as i find time for.. and let me know what you have done with it and your addon's.
