Hi! I just finished building and testing the new N8VEM VDU board PCB
version. It is a 6545 based video board for monochrome character display on
your home brew computer much like a KayPro 10 display. It works OK and
provides a composite video display, PS/2 keyboard, PS/2 mouse and a parallel
port printer interfaces.
It is meant for the N8VEM SBC but the design is general enough it should be
useable on most any Z80 style system. If you are interested in building
your own and/or writing software for the N8VEM VDU please contact me.
When the SBC, ECB backplane, Disk IO board and VDU are combined they offer
the potential for a completely stand alone home brew Z80 CP/M computer. The
software for the VDU is still in development and it
There are pictures and code on the N8VEM wiki in the VDU folder. Schematics
and PCB layout are available. I have several PCBs. Constructive comments
welcome. Please no flames.
Thanks and have a nice day!
