I met and talked with the owner of ACP several years ago and told him of
this listserver. IIRC, he was fairly busy at the time and wasn't
interested in pursuing it then.

 I was at the ACP swapmeet today (in Santa Ana Cal) and the brothers that
 own Advanced Computer Products are putting their collections of 600 old PCs
