- Here's my funky experience with it:
-
- I went out and installed the 50Mhz osillator on my IIsi. I started up,and
- no probs. It was about 20-25% faster than before. After that was done, I
- decided to go ahead and install my NuBus adapter card with the built in
- co-processor and that is when my problems started. I started getting
- really funky screen noise. Sort of like wierd lines drawn accross my
- monitor.
-
- As soon as I took out the adapter card, everything was back to normal
- (except a lot faster). So, from what I could gather, it does not work
- with the NuBus adapter card.
-
- Anyone Out there have similar results? Or did your setup work?
