All –                 I’m working on a VIC-20 project related to another project on 6502.org. I’m looking at two difference VIC-20 schematics for the “cost reduced” VIC-20 (with the drawing number 251027-01). One set is Revision C and the other D. Is there a list somewhere of the Commodore ECOs so I know what the changes are? Thanks! Rich -- Rich Cini http://www.classiccmp.org/cini http://www.classiccmp.org/altair32
