Lol not everyone had a sound card back then. Saddly it does no look like anyone as done a video of the days of audio over the pc speaker. I mean it was mostly un exciting, but there were a few example of great engineering feets. Some games that used MOD music (usually if it was done on AMIGA first and ported to pc) mixed the digital music into a mono WAV form and used the interrupt heavy digital audio output over pc speaker method. I owned a game that I can no longer remember that had a custom audio track that was fairly simular, and rapidly alternated between 2-3 instrument tracks for a fairly convincing melodic background music without the huge performance overhead trying to do MOD music over pc speaker had.

If it isn't obvious, I was a huge audio fanboi back then. Started with my C64 and SID music (I even owned the external SID cartridge for 6 track stereo music), and when i got my first PC (486) I picked up a 2x cdrom and sound blaster PRO (had to have dat stereo sound) for my birthday.

I had a "Freddy the Fish" CD do this inside my computer right after I got my 52x CDRom - I have no idea how I managed to get the bits out but it worked fine after that and never happened again...

Ahh yes, my favorite past time, midi music. I picked up my first cd rom drive and with it, the must have cd game of all time, 7th guest. 7th guest was a SVGA game (That sucker was 8 bit color! 256 colors and some how they pulled off transluscent digital video footage over the back ground) that used Midi for all its music. I discovered the game had an easter egg, the 2nd disc had a red book cd audio track of most of the games soundtrack played on the SCC1 roland board. After hearing just how good these midi files could sound, I quickly got into the world of PC Midi. I upgraded my SBpro to an SB16 multi cd, this monster not only supported the proprietory connector for my cdrom drive, but also an MPU expansion connector for a midi daughter board. The first daughter board I got was creatives wave blaster, but it was pretty weak. I figured out if I wanted a really good midi sound, I would need to plunk down some seriouse cash, and it would probably need to be from roland. So I picked up the roland SCD-15 (I still have that thing! but nothing to plug it into now) and while not quite as good as the dedicated SCC1, it was enjoyable. (http://www.youtube.com/watch?v=rJlkz6V0VOQ to hear how it sounded)

I picked up the SBlive as soon as it came out and proceeded to knock several megs of instruments into that sucker as well. I even put together a sound font called musica theoria (its hilarious when I google that now). My thirst for playing with midi music now is dried up now, but I have a sizeable collection of chip music, sound tracks from my fav gameboy/genesis/snes/ps1 (the entire final fantasy 7-9 series is chip music) so I can hark back on old memories of how music evolved over the decades.
