I have a MVII with a working tk50 and a couple of MV3100s and 4000 systems, all with tz30 drives. I am archiving my 60+ TK50 tapes to better media and I would be glad to add the two tapes to the pile. You go back a ways. I know Neil pretty well and have dealt with him for about 20 years. Back then, Heffron's was a pretty neat used electronics place... I'm in Boston a couple of days a week. joe Heck
