Looking for this rom code.
It is part of the Kurz-Kasch TC-590-89 kit for Midway 8080 boards which consisted of
8080 module Clips B3, D3, E4 #0500021 - which is a small circuit board with the rom on it, that plugs into socket H
all I need is a copy of the rom data.
Thanks Tim
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.
