Looks like a fun project! I bought a macintosh Performa 636CD with 14'' performa plus display, 14.4K modem (external), keyboard, and mouse for $35 at Goodwill about 2 years ago. I just recently gave it away! But I thought their prices were WAYY too high. I was looking for a P-166 for a server project, and they wanted $200 for one! The reason the mac was so cheap was because the guys had no clue what it was.
