- There are lots of other clock sources in there for clocking the SCC
- (serial chip), so I don't think the CPU osc would be used.
-
- My si is running connected to the 57 MHz video osc, and is functioning
- as a server to a variety of machines, and prints to a Personal LW NT
- and a LW II NTX just fine.
-
- It might be a good time to check that your cables were plugged back in
- to the right places... although I expect you've triple checked already.
-
- Did your serial port work with the 50 MHz osc?
