Thanks for the replies about Heath/Zenith computers. I like them too, search my Web domain. As I noted, it's a computer brand owned by many people, it has an interest outside IBM PC compatibles (test equipment, radios, computers before/during the IBM PC). So there's interest and knowledge, but prices are modest because of weight (shipping) and lack of rarity. I think $150 + $50 and up shipping for a Z-100 is exceptional. For some reason, estate planning came up in the thread. I suggest for further discussion or to reply to my comment, start a new thread. My comment is: it's not about spouses. The issue is the same with children and relatives who find themselves with collections they don't understand and/or are not interested in. That happens often enough. End of comment, reply in a new thread to that. Herb -- Herbert R. Johnson, New Jersey in the USA http://www.retrotechnology.com OR .net
