  I reviewed my old BGMicro orders and found it to
be LED1059, which
 is no longer available. 
There don't seem to be any ready sources for this particular display, but I
found that Osram apparently took over Siemens' opto products and *still*
lists an very similar device, the PD353x series:

I should locate some of these and do a Tiny-8 PCB run, but I also am lacking
8008's ;-(

I have an 8008 and HDSP2132 (8 char version).  Wire wrap and a software 
patch will have to do.

The 8008 appeard in one place thats common the 11/34 KY11 programmers pannel.
Possibly others.

I may not duplicate the design exact;y as you did it.  Rather than memory
mapped I may implement IO ports.  However looking at your design there
there some design simplifications that hadn't occured to me last 8008
project (1974).  It's pretty cool and saves a carload of chips.  Most
people back then were implementing multiple busses (address, ram data,
IO in, IO out, interrupt instuction) and thats a lot of chips. The MCS-8
is a really good example of getting carried away with multiple busses.
I hadn't looked at that chip in years and that was a different 
perspective.

You could create a CPU, memory and IO card set.
