It's not nearly the same as the AY-3-8500, but I just dug up my copy
of _How To Design & Build Your Own Custom TV Games_ by David
L Heiserman (1978). He describes systems based around TTL and
linear IC's, some of them rather involved (over 100 SSI/MSI
packages, in some cases!)

Of course, there are no microprocessors involved... :-)
