Hi Raoul
I have the schematic for an Intel 80/10. This is one
of the early 8080 SBC's that Intel sold( I think the 80/05
was first ). Many of the parts would be vary hard to find.
I would recommend doing a 8085 if you can. These are a
lot more friendly. Other than an address latch, the rest
is more like just tacking on various bussed parts. I don't
recall but I think there are some simple circuits in
the Intel 8085 manuals I have.

Hello,
I am looking for circuit diagrams of the original 8080 / 8085 to
construct a prototype board
Any hints?

I can provide schematics of an 8085 SBC which includes a processor,
minimal RAM, ROM, serial, CTC, and parallel.

I don't think it's very hard to make a "minimal" 8008
system, even buffered. I used a 8080, 8224 clock
driver (not hard to find), a 241 and a few 373's for
the address buffering, a 138 to decode memory on 8K
boundaries, a pair of 2114's and a 2716 on my demo
display board. All are available from Jameco. a 7404
and an 00 were the only other TTL on the board. I'ts a
pain to come up with the +12 and -5, but still, not a
big deal.
The "hard" part is finding nice, displayable
components instead of second-source junky plastic
chips.
