I have a partial emulation. I have completed the PIC7040 (CPU), AY8910
(PSG), and RAM. But the SPO256 (speech chip) is still not emulated in

So it's not that useful at the moment.

In fact it isn't even in the mainline code base. It sits quietly in a
feature request in the MESS bugzilla.

The only bright spot is that the SPO256 is _completely_ understood and
being emulated in other projects. No one has done it for MAME/MESS yet.
