"Dennis Wingo: I thought this was interesting and since I am always looking for spares for our LOIRP FR-900's I check it out on eBay. ... When I looked I was pretty certain that these were boards from our FR-900 machines. It had the right part numbers, so I called Ken Zin at home the night before Thanksgiving and asked him to verify, which he did and noted that these are newer version boards of the ones that we have!! So I bid on them and won them today."
