FWIW have had some luck selling large items on ebay, mostly arcade cabinets and such. For things that are collectible like old computers folks will both buy and organize their own transport. And if they don't, we've got a forum member here who can organize freight shipping. Another option is to part it out and ship smaller items that way. There is a demand for such items and you can find old Burroughs parts on ebay in the Sold section for good prices.
