Austin Powers
Stern, 2001I just received a new CPU EPROM for Austin Powers (after installing a newly burned EPROM upside down!). It still does not boot. I get garbage on the DMD and neither LED next to the CPU is lit.
Did I manage to damage something else when I installed the other one backwards? What is the most likely culprit?
Thanks!

Probably not. I've had a few customers install game roms upside down, and all it ever did was ruin the EPROM.
What happens if you put your old CPU ROM back in?
Look to see if you bumped any connectors on the board.
Look to make sure the EPROM is fully seated, no legs rolled under the chip, or hanging out the edge of the socket
Quoted from johnwartjr:What happens if you put your old CPU ROM back in?
Same thing.
I reseated all the cables and connectors, to no avail.
I did notice, however, that I had also managed to install the 4 sound roms upside down 
Fixing those did not help, although I imagine they are toast now as well.
Even with these blunders, shouldn't I still be getting the 5V led?
I'm not above reseating everything again if you think it would help.
Thanks for the reply!
edit:if it helps, the GI is comming on
99% of the time, installing an EPROM upside down will ruin it.
I don't have many whitestar games, so my troubleshooting ability is questionable beyond basic stuff. Are all the fuses good? Perhaps you have no +5 LED because you have no +5?
The GI is powered by its own transformer winding, and will come on whether the game boots or not.
Good call! Sure enough F23 is blown.
Could that be a direct result of my carelessness with the EPROMS?
Also, do you sell unprogramed eproms on the cheap? It looks like I will have to replace all of the sound roms.
I still can't belive I did this
I have another Whitestar game I can steal a fuse from. Would it be worth throwing it in?
My wishful thinking that maybe it blew a fuse from the CPU being installed incorrectly and the sound roms might be OK. (Very wishful thinking)
I'm just paranoid I have damaged something else.
You have John Warts attention...and thats a good thing. He knows his stuff. I blasted a board on LOTR and had problems with it for a couple of years until I replaced the EPROM on the display board too. That finally took care of the last of the problems.
Thank you John (and everyone) for the input!
I have played a few test games and it would seem that the following happened (please correct me if I am missing a potential problem):
Installing the CPU EPROM backwards blew the F23 fuse. It seems that this blew before it could reach the incorrectly installed sound roms. I replaced the fuse (after reinstalling all the eproms the correct way) and, voilà, everything seems to work!
All seems to be working fine. I get very paranoid when a fuse blows. I cannot tell you how ecstatic I am that it is working again.
My girlfriend and I wish to exclaim a hearty spasiba!!

Great news. Perhaps this is one of those few times it was really 'just a fuse' 
Early on, in my collecting 'career', I bought a 'project' Taxi for about $400 shipped. It, too, turned out to be 'just a fuse', new mains fuse and it fired right up.
Enjoy it. Glad you get to Play it all weekend instead of waiting on parts!
