- There was one weird "feature" which Forex copied when they cloned the
- OPTi chipset... if MASTER# is pulled active outside of DACKi#, then
- the system resets. This occured a lots of times when DREQi was
- removed ahead of MASTER# to speed-up the already slow handshaking.
-
- If this is what everyone was referring to, it went away when the 385
- chips were no longer being used.
