+ Yamaha PSR-340 PortaSound keyboard
+ Preliminary driver by R. Belmont
+
+ CPU and Sound: SWX00B, which is an H8S/2000 series CPU and Yamaha SWP00? (or SWP30?) on one chip.
+ LCD controller: KS0066U (apparently equivalent to Samsung S6A0069)
+ FDC: HD63266F (uPD765 derivative)
+ RAM: 256KiB, 2x uPD431000 or equivalent
+
+ TODO:
+ - Figure out correct CPU model. H8S/2655 seems to be the only H8 model in MAME where this actually boots, so it at
+ least has similar or a superset of the 2655 peripheral layout.
+ CPU is at least H8S/2xxx, and may be H8S/26xx like MU-100.
+ - LCD (it's similar to the MU-5's)
+ - Front panel / keyboard scanner (6305 with internal ROM manages this on hardware)
+ - Sound generation
