Howard Cantin is the artist who laid out the PCB designs for the Apple-1 and the first Apple IIs, as well as several early Atari products for Nolan Bushnell.  Mike Willegal, creator of the Brain Board and the Mimeo 1 Apple-1 replica kit (among other things), interviewed Cantin by phone yesterday.  While the conversation wasn’t recorded or transcribed, Mike has posted extensive notes on his blog.  Definitely worth a read if you’re interested in the design of very early Apple boards.
