Z80 NE REPLICA

 

by Paolo Pinto

 

 

 

 

 

Paolo Pinto made a computer replica by making printed board circuits of most important boards.

Sometimes boards where slightly changed and optimized. For example on CPU board revision 3.0 all ram and eprom were removed, and on LX.388 video board there is a new input for a PS/2 keyboard.

 

You can find gerber files of Paolo Pinto cards to make printed circuit boards in the printed circuit boards section.

 

The PS/2 interface has been made by Pino Giaquinto. In the "Add-ons and Researches" section you can find files needed to program the PIC 16F628A.

 

The CPU board lx.382 has been reworked to version 3.1 by reducing components number. Here you can find schematics: lx.382 version 3.1 schematics.
