The JVS-PAC was my first electronics project, and went through 4 hardware revisions.
1.0 - May 2008 - Green PCB - the original
1.5 - Jan 2009 - Black PCB - most components surface mount
1.6 - May 2010 - Blue PCB - all surface mount components
1.7 - Sep 2012 - Red PCB - professionally manufactured
The last JVS-PAC was shipped out December 2017.
