2020-01-22 19:34:10 -05:00
Thomas Harte
a71c5946f0 Ensures proper manipulation of scan_statuses, leading to the correct result out of a CRTMachine.
Possibly with the exception of the TMS, as I appear to have uncovered an unrelated issue there.
2020-01-21 22:28:25 -05:00
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

c1bae49a92 Standardises on read and write for bus accesses.
Logic being: name these things for the bus action they model, not the effect they have.

da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT.
