I have my Rare Heathkit RT-1/ RTW-1 Hero Jr. Robot Service Data Blue Book Technician Manual up for sale. The copyright is September 1984. It is in decent condition (minus some dirt on the edge of the manual view photo) with no writing inside the manual. View photos for details and condition. Feel free to ask questions. Thanks for looking!

P.s. I am currently working on Heathkit listings and 1000s of listings are coming, unless I can find a bulk buyer (recently acquired a MASSIVE LOT). Feel free to pm me about my lot!
