One large piece of veroboard (stripboard for those across the Pond :-))
on top of the case for all the logic (that way you coupld probe at all
the IC pins without extender cards). Another somewhat smaller piece of
veroboard on top of a similar case for the CHAMP-PROG (1702 Eprom
programmer). This was a 4040-based machine, of course.

I should still have all 10 artictles for the CHAMP, CHAMP-PROG and
CHAMP-UV (EPROM eraser). But don't even think of building one now -- just
about all the LSI parts (CPU, RAM, memory interface, EPROMs, etc) are
almost unobtainable.
