- Yep, that's it. And another problem is the metastability of whole system
- when CPU is at double the clock of bus. The FX has the best settings I
- can imagine (123I DM2), but it still often hangs :-(( I can't imagine the
- black magic needed for solid 50 MHz CPU. BSS are quite clever they go
- only for non doubled CPU clock. The bus is the slowest part of Falcon,
- anyway.
