What is so great about the SID chip?

[Britelite]

I had a disk of SID music way back then so I know it plays music and stuff, but it only reminded me of .MOD music...

Umm, SID-music sounds nothing like MOD-music (except when playing mods). The similarities might ofcourse come from the fact that there are a lot of mods that try to sound like the SID

You don't see FM based Soundblaster cards with patches to play PCM type samples on PC do you?

Actually, yes you do. There quite a few mod-players that even worked with the good old Adlib-card. The Soundblasters all had a DAC, so there was no need to play sample with the FM-chip.

Maybe there was more than one type of ADLIB card

I was referring to the original Adlib-card that only had a FM-chip, and still people were able to play samples and mods on it.

certainly the original sounblaster (not SB-16 etc) from early to mid 80s did FM based OPL stuff no?

Yes, the soundblaster had FM-chips (mainly for adlib-compatibility) but every single one of them also had a DAC for samples.

Anyway, my point was that we all know the Amiga was impressive and awesome, so there's no need to make thing up about the PC to make it look bad, it had many faults but please stick to things that are actually true

The Adlib card had no digital output and I don't believe was ever able to play MODS...

And that's where you're wrong, I've played a lot of mods on it

The SoundBlaster(which I called the "Sandblaster") was Adlib-compatible but had 1 8bit sound channel which a fast 386/486 could mix 4 (amiga/mod) channel sound into a single channel.

Actually, playing 4-channel mods with software mixing on a soundblaster was possible even on a 8MHz XT.
