Hi,

I uploaded the initial schematics for ECB PropTerm:
http://n8vem-sbc.pbworks.com/w/file/63550295/ECB%20PropTerm%20-%20Schematic%20-%200.1.pdf

Basically it is a ParPortProp together with an 8255 PPI and ECB
interface attached.

It provides simple and reliable terminal (and also SD card storage)
capabilities to ECB systems.

Perhaps schematic can be simplified a bit (I think 74LS241 buffers on
EBC are redundant).

I'd like to get any comments and suggestions...

Thanks,
Sergey
