I'm leaning more toward the 7000 series. I just haven't found out much about the TAS series. I'm worried that, being about the last of the analog scopes, that they might have a lot of custom parts. Besides, a 7000 series with 7A24 or 7A26 plugins will do what we need and be repairable too.

Looking back at the archives I don't see much on the TAS485. Have you done a search of the archives? I only saw 17 messages related to it. Artekmanuals.com would be a starting place to search out a service manual if one exist.
If I was facing your problem, I would look for or build a differential to single ended amplifier pair to get the signals into a two channel scope. Op amps in the 100 MHz range exist for not much money. There are also Tek differential probes available. That or just get a 7704A or such.
