This was the player I started out with. It uses a Hitachi H8/S 2357F CPU, a 16 bit thingy with 128 kB Flash ROM, a few built in peripherals and a ton of I/O pins. GCC was available for it, so programming would be easy (well, relatively).
The only problem with it, was the package - 120 pin TFP or 128 pin FP, which make it difficult to solder for
the average home builder.
While considering this for a while, I came upon an idea of using an Atmel CPU instead, and
put yampp-1 on ice. It's not dead however, as it offers much more functionality than yampp-2, such as USB interfacing,
better user-interface, more memory e.t.c.

On the left is a PIC controller and a LCD-display, on the right is the USB interface.
