Title: Kramer pcb troubleshooting help please
Post by: mike11 on August 18, 2013, 07:16:45 AM
I have a Kramer poker here I'm trying to get up and running and all I get is a gray screen ...... I've swapped the 8080 with a known good z80 along with reburned the Roms and still nothing ....... Anyone know these boards that can help.   ??
Thanks

You can't substitute a Z80 for a 8080, they are different. Try a working 8080 and see what happens.
