Hardware MP3 acceleration & the Diamond MX400
People have been looking for MP3 decoding cards for years on various retro forums, some exist for the parallel port, such as the one presented by the c't magazine in 1999:
But what about ISA cards?
Well, two did exist (which I don't own), the first from Germany and the other from Canada.
In 1997, the Interactive Technology branch of the german company NSM, mostly known for jukeboxes, made this:
the TrueSound Decoder
Technical requirements were a 386DX or better, 4MB RAM running MS-DOS, Win95, NT4 or Linux, or even Amiga machines with an adapter for ISA cards.
The first version could decode MP3 files with a bitrate of 32kb/s to 128kb/s, the second version of the card could decode from files upto 320kbit/s.
More than one card could be used in a single PC, upto 3 in DOS or Win95 and 2 cards in NT4.0
