Support FORMAT cmd:
. HDC firmware: byte $FE, b3=1 (format supported)
. HDC firmware: allow both SmartPort and BLK FORMAT cmd (and check that SP FORMAT only has 1 parameter)
SmartPort Controller:
. Format will just zero all blocks (if not write-protected)
. Write cmd: if write-protected return NOWRITE
. SP Status cmd: 'General Status': set format-allowed & write-protected flags
If HDD image is read-only then support as write-protected.
. On Insert() setup m_bWriteProtected flag correctly
Added new SmartPort Harddisk Controller (HDC) firmware for Enhanced //e. (@burniouf)
. remove the old DOSMaster entrypoints.
. firmware ID byte (at $FE) defaults to 4 ProDOS block devices (was 2 with older v2 f/w).
Enhanced //e defaults to using SP f/w, and older Apple II's still use the older v2 f/w.
Support up to 8 units per HDC (currently limited to 4GiB capacity for each unit).
Save-state: save HDC firmware in state file.
New slot-specific switches to configure each HDC's firmware: -s<N> -hdc-[sp|bm2|bm4].
New switch to select old non-SP firmware for all HDCs: -hdc-firmware-v2.
. A phoneme will continue playing back infinitely; unless the phoneme is changed or CTL=1.
. Reset doesn't affect SSI263/SC01 (so phonemes continue to play).
. CTL=1 sets "PD" (Power Down / "standby") mode, also set at power-on.
. CTL=0 brings device out of "PD" mode, the mode will be set to DR1,DR0 and the phoneme P5-P0 will play.
. Setting mode to DR1:0 = %00 just disables A/!R (ie. disables interrupts), but otherwise retains the previous DR1:0 mode.
. RESET is not connected to !PD/!RST pin 18.
. Support edge-case where RESET can enable ints & assert IRQ.
. Power-on: PD=1 (so D7=0), reg4 (Filter Freq)=0xFF.
. Support SSI263 IRQ and D7 on a Phasor mode change (including Echo+).
. $Csxx I/O mapping (same for Mockingboard and Phasor mode).
Other:
. SSI263 save-state: support SC01 as a sub-unit of the card.
. 6522: Fix reg $F (ORA w/HS) to be identical to reg $1 (ORA).
. Command line config only, and only permitted in slot 3 for now.
. Save-state Unit v9: Extended: memory (added 'Last Slot to Set Main Mem LC', 'MMU LC Mode').
. Add LanguageCardManager class.
