Please bear with me.

I have a Roadblasters machine. I bought a RoadRunner PCB. Should this be plug and play?

It was listed as wrking. I plug it in and get the following errors:

BANK SWITCH ERROR

ROM AT 020000 ERROR 0 08FF
ROM AT 028000 ERROR 0 38FF


Was I wrong in assuming this board wouls plug and play with Roadblasters hardware? Or did I perhaps get a bad board?


Thanks,
Chris
 
should plug right in where u took out the rb daughter card... try reseating chips on the roadrunner card and make sure the two bds are plugging together properly..
 
should plug and play but I have seen a cartridge work with one main board and not another. Honestly there should have been no reason it wouldn't work but it didn't.
 
i thought that the only one that may have been special was marble madness. i know that RB and Indiana Jones is swappable. i would do as mentioned above and reseat and double check the connections.
 
Well... from my recent MM repair, I found that Bank Switch Error is typically a bad Slapstic, but in my case it was a bad ROM. If the board is supposed to be working, and your +5V is good, maybe there's also an incompatibility between some boards... I really don't know.

Thanks everyone, I will try re-seating the ROMS and see what happens. The seller is very nice and offered to burn me replacements if needed, so I do have an option if that is the case. I will also be trying it in another cabinet to see if it's something with my Roadblasters machine, though Roadblasters works fine.

I've seen system 1 errors from:
- low +5vdc
- dirty edge connectors between the main board and the cart
- wrong ROM jumper settings
- slapstic issue
- bad game cart

good luck
 
FWIW, sometimes my MM will display the message "Software Exception Error". I have no idea what this means, though...

I seem to remember some discussion of a different style of system 1 board some time ago. I believe it came from when phet was possibly going to acquire some system 1 parts. I also recall that the cockpit road blaster uses a different style system 1 board.
 
Dont worry you have the normal mother bd on top and daughter card set up on bottom just like I would say 99% of us....I have never seen a stacked set up like that either....My guess since you are getting the messages on screen is that you are seated together ok and just have a bad chip.. or two...
