[XCSSA] Tim, are you going to the meeting on Monday 18th ?

I just checked my SIDs and they are both 6581...
One is 6581 and the other one is 6581 R3 if that makes any difference.

I'm not building a MidiBox but I'm planning of making a "sound card" for 
my 6502 project with the two SIDs.
However before I start building it would be nice to know if the SIDs 
still work... ;-)
But it's no hurry so bring them home, test them and bring them back to 
the next meeting or so...

I'm glad you got your order in, you'll have to make another demo when 
everything is finished.
Or record a CD... ;-)
Speaking of CDs, I have two CDs with remixes of C=64 tunes somewhere, 
I'll bring them as well...

/Fredrik
