New clones marked as NOT_WORKING
--------------------------------
Poly 1 Educational Computer (early) [Nigel Barnes, Andrew Trotman]
Poly 2 Learning System [Nigel Barnes, Andrew Trotman]
Poly Development System [Nigel Barnes, Andrew Trotman]
Merged with strnskil.cpp, with modernization and cleanups. (nw)
Add MCFG_SCREEN_RAW_PARAMS. (nw)
Added coin counters to markham, strnskil, banbam and clones.
* proposal: move z80daisy* to devices/machine
Seems to me this is a machine, not a CPU? Main reason was to stop the Z80 CPU from being dragged into systems that don't have one just because they use a Z80 family peripheral.
* missed this one (nw)
* missed a spot (nw)
* interpro: slotify mouse (nw)
Needed to make the mouse a slot device to enable it to be connected to graphics boards under development.
* add validity check (nw)
* bt45x: new devices
Basic implementation of various Brooktree RAMDAC devices. Two of these (bt457, bt458) are used by InterPro graphics boards currently under development, the others are unused/untested at this point.
* bt45x: tweak descriptions (nw)
Start replacing special device macros with additional constructors,
starting with ISA, INTELLEC 4 and RS-232 buses.
Allow an object finder to take on the target of another object finder.
(For a combination of the previous two things in action, see either the
INTELLEC 4 driver, or the Apple 2 PC Exporter card. Also check out
looping over a device finder array to instantiate devices in some
places. Lots of things no longer need to pass tags around.)
Start supplying default clocks for things that have a standard clock or
have all clocks internal.
Eliminate the separate DEV versions of the DEVCB_ macros. Previously,
the plain versions were a shortcut for DEVICE_SELF as the target. You
can now supply a string tag (relative to current device being
configured), an object finder (takes on the base and relative tag), or
a reference to a device/interface (only do this if you know the device
won't be replaced out from under it, but that's a safe assumption for
your subdevices). In almost all cases, you can get the effect you want
by supplying *this as the target.
Eliminate sound and CPU versions of macros. They serve no useful
purpose, provide no extra checks, make error messages longer, add
indirection, and mislead newbies into thinking there's a difference.
Remove a lot of now-unnecessary ":" prefixes binding things relative to
machine root.
Clean up some miscellaneous rot.
Examples of new functionality in use in (some more subtle than others):
