The Merlin PFC was a great concept (in theory), but with most Merlin products required specialized parts; the paper used to fill it was 1/2" core where as the huge majority of thermal fax machines of the time were 1" core. I still have mine, even though I don't use it, I still have a litle niche for it in my heart. Then again, I packrat all my Merlin stuff...even my Merlin Plus data collector for SMDR.
