-To-do list (Tom)
-================
-
-This is a (non-exhaustive) list of stuff that I personally would like to get done:
-
-(14/8/2014) Having moved all non-system headers out of stdafx.h, it looks like
-  many headers are included just to call Init() or Reset() methods for Apple II sub-systems.
-Cut down on the headers by:
-- Using the Visitor pattern (for all Apple II sub-systems)?
-- Or just a vector which contains all sub-system Reset() methods?
-
-. Consolidate the Spkr_SubmitWaveBuffer() & Spkr_SubmitWaveBuffer_FullSpeed() funcs.
-This will make the code cleaner & simpler.
-
-. Software mix Speaker & Mockingboard waves before submitting to sound-buffer.
-This will:
-a) fix the problem with speaker sound be rough when MB is active.
-b) probably fix the problem with other processes having problems playing sound at the
-same time as AppleWin. (Although I've not experienced this)
-c) hopefully simplify things :)
-
-. Run emulation (or message-pump?) in a seperate thread.
-So that the sound is continuous when dragging the window or starting other applications, etc.
-
-. Add proper Votrax support (using PinMAME samples & code).
-
-. Fix SSI263 so that phonemes are overlapped (like Votrax).
-
-. Save-state supporting Phasor, harddisk & Ramworks III
-
-. Support for switching display modes mid-frame
-To support Bob Bishop's intros, tight-loop page-flipping, etc
-
----
-
-Plans for (1st pass) cleaning up are:
-. Ditch the x86 code to access the PC speaker + ditch PC speaker support
-. [DONE] The arrays ioread[] & iowrite[] in Memory.cpp should be switched from units of 1 byte to 16 bytes.
-  This will yield 256 entries spanning [$C000…$CFFF] – currently it’s only [$C000…$C0FF]. This will mean that:
-	a) cards with I/O mapped above $C0FF (eg Mockingboard, Mouse?) don’t have to be kludged as in the READ/WRITE macros in CPU.cpp
-	b) $CFFF (ROMs out) can be emulated
-. Talking of CPU.cpp & those macros: I’d prefer to replace them with inline funcs. Maintenance of these
-  macros is a bitch & they can’t be single-stepped. Inline funs should yield the same code (in release build)
-  as the macros.
