If it would be any help to you guys, I could simply merge the posts from the earlier thread to this one (but there were only two posts involved). So if you'd like them included here, please advise.
Jeff, are you certain that this series is now in the public domain? If so, I will (reluctlantly) open the earlier thread. That is, if the eBay-listed discs are legitimate, then there's no problem. Thanks.
