Re: Twiggy Drives

James those are some fantastic pictures. Maybe when 3D printing technology progresses the point where metal printing at a small scale is cost effective....someone will print up a new twiggy drive. I've followed Lisa-1 parts on ebay and I've only seen 1 set of drives for sale in the early 2000's...went for big bucks too.
