Connects up an SCC.

Thomas Harte
294e09f275
All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

Thomas Harte
d97a073d1b
Adds the necessary routine for all machines to be able to respond to get_scan_status.

They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.
2020-01-20 21:45:10 -05:00
Thomas Harte
c1bae49a92
Standardises on read and write for bus accesses.

Thomas Harte
962275c22a
Removes clock for NCR 5380.

It doesn't have one in real life, and now can live off the time counting that occurs on the SCSI bus.
