I'm beating up an Omega Race board right now for a customer and I find it is not very pod friendly. I found that if one clipped pin 8 (9? - I'm at home right now) of the final reset stage and tied it high that this would deal with the negative RESET stuff. I had a lot (8) of the 2114's that were bad and ended up making my Xeltek Super Pro be able to test those suckers as I do not have a stand-alone RAM tester that would handle the 2114. Problems with reading the Vector ROM/RAM have yet to be solved, even had trouble reading the game ROM for a while - flaky 74LS138. I hate getting working on these corroded boards. Not worth my time, yet too much of a challenge to discard...I love puzzles too much! John :-#)# At 12:36 AM -0800 1/22/07, Matt Rossiter wrote:
This might be more of a Vectorlist question, but I thought I might try here.
Right now I'm using a 100% working Omega Race boardset to make sure I have the correct setup using the Fluke 9010a and Z80 Pod.
First of all, the boardset just won't run with the Z80 Pod. I can see that the Reset line is pulsing. It won't run if I disable the watchdog circuit either. *sometimes* I can get it to do a Quick Ram Test successfully. Other times I get data error messages and if I do a bus test it will report a bunch of data lines tied together. Of course, if I put a normal z80 processor back in the game works perfectly fine.
So, I'm just wondering if anyone out there knows how to properly setup an Omega Race boardset for troubleshooting with the Fluke 9010a and Z80 pod. This Pod should be working fine since I used it recently on a Pac-Man.
thanks
Matt
