RS232 &Current loop? crap (NOT FPUIB)

But, is anybody fanatic enough to want to BUY an Atlantic Research Corporation Data Tek 9600? (sorry, this one is NOT free, but I'll offer it here before eBay) (either bids, or sensible sugestions of what I should ask for it) (no pictures YET; prob'ly later this week) Blue lunchbox 12" X 8" X 5" with detachable lid. Underside of lid has "DATA TEK 9600 OPERATING INSTRUCTION" 120V 60Hz mains power attached molded cord Model label says "Teleproduct\nAtlantic Research Corp Model DTS-1-4-M519?
