Hi
 It sounds like it is missing the processor card. Still, it may
have one but it doesn't interface with the front panel. The only
signals that run through the ribbon are data signals. All of
the rest go through the bus. This means that if you don't need
the ability to used that readouts of the panel, you can do
things like reset and run without the ribbon. Check to see
if there is some other processor card there.
 I see original 8080 cards on ebay often but there were many
second source Z80 cards with the ribbon cable connector made
as well. I see these very often on ebay. Just keep an eye out.

 So, install a new cord.

 Take pictures. Put them on a web page. Note any text found on boards.
