Hi Tim,

Chances are that is simply a jumper block that shorts D0 - D7 all to
ground. I doubt it is anything else...that is the DATA setup required
for Signature Analysis on the 8080 CPU based games.

KK used to do things like that, make a blob of a jumper circuit so they
could sell the blob for $50 or so...

I made one up using a dead Eprom...cut all the address pins off leaving
just the Data ones that I then jumpered all to ground using fine wire
soldered to the shoulders of the pins. If you want to get proper you
could tie the Chip Selects to Vcc (turns off the Eprom) then it will
present the least load to the power for the system.
