MOS6581

[CasioRZ1 at aol.com]

Hi All,

I've also been working (and am almost through w/) a PIC to sid project.  It 
doesn't store patches or have a cool LCD display like the sid station, but it 
receives midi note on/off, lets you select waveforms, play w/the filter... 
the simple stuff.   

When I'm done I'll post the code for it if anyone's interested... it's 
written for the Scenix SX.

Oh, BTW, the C-128 also has the 6581 in it in case you're out commodore 
scavenging.  Also, there's a different version of the 6581 in later 
C64s(?)... I can't remember the number right now, but it has slightly 
different voltage requirements than the 6581.  Oh, and BTW BTW... if anyone's 
lookin fer some complete (minus the SID) commodore 64s, i've got some for ya. 
 ;-)

 I have a  midi-2-PIC-2-SID idea in my active project file....So
 if you ever wanted to play with this chip now would be a good time
 to start looking for a old "tan-hump" C64 to grab a 6581 out of. If
 you are serious you might want to get more than one they tend to be
 a little flaky.  I don't know how long it will be before anything 
 actually comes of this. It's been active for almost a year now without 
 a single line of code being written.  I have the instruction-set and
 application notes and am finally getting the hang of PIC-programming
 so who knows? I doubt it will be as complicated as the SID Station
 but I think it could be useful. If I ever get it built, I guess  I'll have to
 give Jim's SID back so he can play too....;-)
