Constructor & Destructor Documentation

◆ WD2793()

openmsx::WD2793::WD2793 ( Scheduler &  scheduler_,
DiskDrive &  drive_,
CliComm &  cliComm_,
EmuTime::param  time,
bool  isWD1770_ 
)

This class has emulation for WD1770, WD1793, WD2793.

Though at the moment the only emulated difference between WD1770 and WD{12}793 is that WD1770 has no ready input signal. (E.g. we don't emulate the WD1770 motor out signal yet).
