The speech on my Berzerk is fast. Like listening to A 33 1/3 LP played at 45 speed. I replaced all 3 of the Eproms on the VSU 1000 board. but I'm still having the same problem. Any help would be greatly appreciated.
Thanks,
Tony
 
coindetectedinpocket! Chipmunk-Berzerk might be pretty cool.

Disclaimer: I'm no Berzerk expert...

Looks to me like speed data must comes in thru B6, then counters thru A6 & A5 (presumably to create a frequency some amount slower than the CPU clock freq), then finally fed into the clock pin of the speech synthesis IC (C3). A few inverters in A4 are also used.
 
Berzerk Speech Problem

It is kind of cool, but tough to understand. Do you think A6, A5, and A4 need to be replaced?
Thanks for you help!
