Collecting 1970's and 1980's computers is one of my hobbies, although, not so much these days as I've run out of places to put them in the house, unless it's a particularly rare or pristine condition one.
One of the most popular computers of the 1980's was the Commodore 64, not only because it had a great graphics chip, but also because it had a great sound chip, namely the "SID chip", or to give its technical name, the MOS6581, later changed to the MOS8580. See http://en.wikipedia.org/wiki/MOS_Technology_SID
There are several microcontroller emulators for the SID chip knocking around the internet, some are created using 32-bit processors or FPGAs, but some are created using 8-bit microcontrollers, and all based upon the Atmel AVR types for some unknown reason. In fact, for some strange and disturbing reason, most really interesting creations with 8-bit microcontrollers seem to be based upon the AVR, and have been for many years now!
However, to readdress the balance in some small way, I've produced a simple SID chip sound emulator using the free Proton Amicus18 compiler, which I think is the first of its kind for a PICmicro, and certainly for an 8-bit device written in BASIC, which just goes to illustrate the power and flexability of the language
