It seems to me to have been a kit given to customers of IBM as a token of appreciation for business. I've come across 2 of these. One was owned by a friend locally, the other was bought off eBay for a local collector. I appraised the second one when the collector donated his collection to the Computer History Museum. The appraisal was in the thousands of dollars. Here are some responses that the first owner I referred to solicited from various people (whose names should all be familiar): http://home.pacbell.net/mmetzler/treasure.txt And here's his page about it: http://home.pacbell.net/mmetzler/vacuum.html -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
