Long answer: Proper programming requires some readback, which must be done individually. I guess in theory you could assume all the chips out there were identical, program them write-only once, then switch to separate readbacks. I don't know of anyone that actually does that. If you care about this then you must be programming a lot of PICs. In that case use multiple programmers. > PS: Olin, your USB programmer is impressive! Thanks.
