* a new entry in the list of clones and a dedicated RUN button
* has differences in IMC2001.rom to support Apple ][e like
lowercase characters in the monitor ROM
* the video ROM for 40-character more IMC2001-Video.rom is quite different
(mainly to support lowercase ASCII characters in NORMAL mode)
* the keybaord act more like a Apple][e, decided to use the CAPS mode
switch as for the Apple][e in the emulator
* TODO: support for special keyboard features like the separate HOME, DEL,
UP, DOWN, LEFT, RIGHT block of keys. Also F1 to F12 keys which are
hard-coded in the keyboard ROM (with a switch for APPLE and CP/M mode)
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.
