How to find an interested buyer? - I know Ebay, but that is a 7 day window for what I would presume to be a small audience of interested parties - and how to value/price it? This was my personal unit, last used in the late 70s to access the then ARPANET. Still powers up. Very Good condition. This was TI's 1st Silent 700 portable data terminal (they produced the 1st Silent 700 in 1969, but not a portable) - per TI's web site - is this collectible?
