The y have used Fairchild for their source. If so, that explains the high rate of failure. Years ago when at Intel, we disqualified Fairchild as a source for parts because of the poor testing and high failure rates. Dwight From: cctalk

SWTPC keyboard foil patterns

Hey guys, In Don Lancaster's 'Low cost keyboard and ascii encoder' article (Apr 1974), he mentions in the parts list that the SWTPC keyboard mentioned in the article had foil patterns available, full size, free on request.  I was wondering if anyone out there had them or knew where they
