aac3d27c10 Adds activity indicators for the BD-500 and Jasmin. 
Also slightly cleans up DiskController a little further.

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.

b035b92f33 Corrects accidental use of sector contents as addresses in multi-sector reads and writes. 
As a secondary defect, this was also causing erroneous CRC error reports.

96bf133924 Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed. 
In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.

73080d6c36 Added an easy way for disk controllers to clamp termination of written data exactly to the index hole. 
This commit also temporarily provides a whole load of extra logging and minor logic improvements from the 8272. I'm mid-flow on finding a particularly vicious error in its handling of writing; wait for the pull request. But, at least: now waits for the first part of a post-ID gap before writing data, and attempts partially to handle appearance of the index hole during writing a track. More work to do on that though.

4abd62e62b Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty. 2017-07-27 22:05:29 -04:00
