Hi, you need to replace the Time Keeper and ZeroRAM chips at locations 200E and 210E on the main PCB. The replacements are M48Z02-150 ZeroPower RAM and a 48T02-150 TimeKeeper RAM
I've done this myself a few years ago on my Hard Drivin', but I took this info from...
Thanks, that's great. So I just need two 27c400 for IC 7&8 then.

Thanks again both for your help & advice. I'll...
Thanks very much for the info guys - Yes, the jumpers are all fine and the TV (it's a PDP-V402) is fine with 25khz (I've played other Model 2 games with this setup).

EDIT - realised my supergun does have those...
Just wanted to say thanks to everyone who's helped with the Pilot Kids jumper settings - got my ROM board working now!
The only issue is that the Test and Service buttons on the PCB don't work - could that be to do with any jumper settings? Those buttons do work when I put a Virtua Striker ROM...
thanks very much - do you mean JP19 & JP20?
it's a little bit difficult to see on your picture - I have them set as follows: JP20=3&2, JP19=1&2. Same as Virtua Striker, as i hadn't changed them!
