I have done Intel 4004 implementation, here is a patch (it also
contain a POC driver for 4004 Nixie tube clock, that runs under MESS).
4004clk is artwork file, and roms file contain needed roms (just rename ZIP).

Miodrag

* Full Inputs.
* DIP Switches.
* Simulated spark-watchdog circuitery.
* Demuxed custom port.
* NVRAM support.
* CPU clock derived from #defined crystal.
* 8000-8007 Output ports.
* Coin related counters.
* Sound components and trigger found at 8000-8003, bit2.
* Full lamps support.
* PCBs layouts & technical notes.
The 4 games are fully playable. Sound seems to be discrete, so the circuitery need to be traced.
Colors are still wrong.

Multi-Poker [Roberto Fresca]
- Added a new implementation of the I8255A device. Rewritten from scratch to properly support handshaking in modes 1 and 2.
- Refactored sg1000a.c to use the new implementation.

Looks like I messed up a few of the driving games. Here are the fixed layout files,
along with a small change in \src\mame\drivers\mw8080.c, as lagunar was referencing 280zzzap.

Johnny Nero Action Hero [R. Belmont, The Dumping Union]
The boot ROM has a lot to say on two different TTY ports (really).

Tokimeki Mahjong Paradise - Dear My Love [David Haywood, Angelo Salese]
Tokimeki Mahjong Paradise - Doki Doki Hen [David Haywood, Angelo Salese]
changes:
- split tmmjprd / tmpdoki from rabbit.c as it uses the graphic chip in a very different way, and having them together was making it more difficult to make progress on [David Haywood]
- changed them to use custom rendering code instead of tilemaps, as they can address tile data at a sub-tile level, this fixes the girls in the intro [David Haywood]
- added inputs [Angelo Salese]
- added some notes about a hang, and possible reason [David Haywood]
- marked the graphic roms of tmpdoki as BAD as it appears to be using tiles which are not present in the tmmjprd roms for the title screen [David Haywood]

No credit please, it's just a skeleton driver with another unknown CPU
(Haze did the gfxdecoding iirc)

Subject: [patch] "Regularize" some interfaces in MAME
Hi mamedev,
This patch adjusts the code in a few places to be more regular in it
object approach. It recognizes five idioms.
1. device_configs should be passed const. dsp56k.h took a non-const
device_config for no particular reason, necessitating casting where
used. A few other places cast to non-const, in most cases
unnecessarily.
2. running_machines should be passed non-const. A few places used
const in different ways on running_machines, instead of the idiomatic
non-const running_machine.
3. Eliminate passing running_machine explicitly where it can be
computed. esrip.c, m37710.c, sfbonus.c had cases where the machine
could easily be eliminated.
4. Pass the object machine/config first. In some cases this makes
the interface object oriented, in some cases it simply makes it more
idiomatic with the rest of MAME.
5. Prefer (screen, bitmap, cliprect) to (machine, bitmap, cliprect).
Fully implementing this would be a large patch, this patch simply does
it for the one core 'device', tms9928a.c.
Namco custom IDs where appropriate.
Added clocks to the Namco 06xx in anticipation of improved
device interconnection.
Added new file devtempl.h which can be used to generate the
DEVICE_GET_INFO function. Updated all the Namco I/O devices
to use this.
Updated galaga driver to use computed video timing.
Updated polepos and bosco drivers to use the new 52xx sound
emulation, wiring up the output through the discrete mixer that
Derrick had already plumbed but left disabled.
This required several MB88xx changes/fixes:
- internal timer support now works; prescaler is guessed based
on Pole Position sample playback frequency
- external counter support works
- a basic mechanism for reading serial input has been added; it
is not sufficient for a full implementation, but good enough
to sample the SI pin at startup
- fixed TSTS/TSTV to clear their respective flags
- fixed CI and CYI to compute imm-reg instead of reg-imm
- added masking of the PA register upon RTI/RTS to prevent bogus
PC values
the information needed to connect to the CPU and other devices
specified in the definition.
Updated drivers to use this new device.
(I notice that the bosco shoot sound no longer changes pitch during
another explosion. Not sure if this was fixed prior or if the
recent device-ification cleaned something up....)
Converted Namco 51xx and 53xx into proper devices. The MB84xx is not
yet emulated, but is now present.
Converted 51xx and 53xx interfaces to use the devcb system for
port I/O callbacks.
Dig Dug is known to be somewhat broken at the moment.
and thief drivers.
Bunch of improvements to the Status system emulation. Correct
video timing, hooked up TMS9927, corrected colors, etc. Still
some work to do.
