Modified HP-28S seen on eBay Message #1 Posted by Ken Shaw on 23 Feb 2007, 7:00 p.m. Here is an HP-28S that just sold on eBay. Item #130080704876 It appears to have a 28-pin connector where the display should be and came with a matching ribbon cable! Anybody have a clue what this might be used for? - KDS

Another (perhaps a tad larger) matrix LCD without backing and see-throgh could be placed on a transparency projector for classroom display... Bill Wiese San Jose CA

This one might have been used to test various different displays.
