- Note: Not all Atari dealers are stupid. :-)
-
- The jumper wire you talk about has to be inserted in Mega STs that have that
- strange extra chip on top of the CPU. We did that, that really is NOT the
- problem.
-
- btw, without the jumper, these Mega STs wouldn't work at all, since the BGACK
- (bus grant acknowledge) signal wouldn't reach the CPU.
-
- The problem with AdSpeed is, some MegaST/TEC machines don't work in a stable
- way; they simply crash from time to time, some have blitting problems, some
- will run in cold state and crash once they become warm - these are not all
- kinds of symptoms I've seen...
