Sounds like a pitch patch system. I thought they destroyed those pre-production prototypes. Value is depending on what a collector would be willing to pay! I read somewhere about a Mac museum! From: Gregg Eshelman <g_alan_e at yahoo.com> Subject: [Duo2400] 280 prototype. 230 engineering sample. Date: Mon, 30 Jun 2003 03:05:40 -0700 (PDT) I have a Duo 280 prototype and a Duo 230 engineering sample. Any idea on value? The 280 has a label on the bottom which says Yeager Prototype Unit- Not For Resale and a warning that it is not FCC approved. The 280's lid has PowerBook Duo 250 below the Apple logo. About This Macintosh identifies it as a 280 with 12 megs RAM. It has the 14.4 modem and a 320 meg Apple hard drive. >The 230 has no labels at all on the bottom but inside on the frame by the >left hinge it has a bright pink label that says Engineering Sample and on >the right end of the frame is hand written in marker Glued and tested >ground clips 3.20.9 _________________________________________________________________ Add photos to your messages with MSN 8.
