Re: TI-H: 8 bit stereo sound! (and more)





Yes... i know someone else has also done this (the Marvin robot team) but
as they arn't releasing details on how to do what they've done.... (and
they were working with internal rom calcs so thiers is a bit differant)

also, i have had the technical ability to do this for quite a while
(since mid '97) but just now found the time to acually build something...
