High Speed
Williams, 1986I am looking at purchasing one of these however the CPU has some pretty severe acid damage on the IC under the battery holder and above the battery holder as well. It was sitting in a garage for 15 years. It maybe repairable but i know the display traces on the back are pretty thin and when I power it up, the display is all screwed up. Coin door switches dont work, etc, etc.
Thoughts...Discuss...
High Speed should have a Sys11 (no letter) CPU.
A Sys11A or Sys11B CPU can be modified to work in High Speed.
They are out there, they are NOT cheap. Expect to spend $300-400 on the CPU, and if you get a deal, or if yours is repairable, you'll be in it a bit less.
At one point, aftermarket system 11 MPUs were available here:

But...as of this month, looks like they are no longer being produced, which is unfortunate.
Rottendog still has their version available from various resellers, as far as I'm aware: http://rottendog.us/MPU011A.html

High speed is not compatible. It's a system 11, not system 11a. Strange one.

Huh. Didn't catch that.
Thanks guys, I will just hold off on it. Its not cheap enough for me to grab at this point. When I find the board, Ill buy it and find the game later.
Quoted from lordloss:Rottondog is good as a last resort, but the sounds are off.
Is there a thread about this I haven't heard that.
Quoted from Mitch:Is there a thread about this I haven't heard that.
Personal experience. I had two whirlwinds once. Rottondog on one and original on the other. the sound differences were pretty stark.
Funny i just saw this thread. I pick up the high speed barn find that started thread. Board was pretty, bad worse than I thought so I pick a referbished one. Had some switch and wiring issues but all resolved. Playfield a little dark but in really good shape for age. Sets up and plays now. Display is speeder 3 out but plan to play and enjoy for now.
