I have an LS-8000ED that turns on, but is not recognized by my iMac (OS10.12); when sent to Nikon a few years back, they returned it to me un-repaired, citing the discontinuation of a part required for the repair. I've been meaning to either purchase a for-parts 8000ED and/or try to DIY a fix, but just have not had the time to do it, and I don't see myself ever doing it in the future. Thus, I offer it here for cheap. Looks great, cosmetically. Nothing is guaranteed in terms of mechanics/electronics. $200 + shipping and PayPal Fees. I also have the coveted FH-869G holder for medium format with all masks. Great shape. $400 + shipping and PayPal fees. I also have the original holders that came with the 8000ED (35mm and medium format). Take all for $300.
