Re: HP1631D Logic Analyzer..Software???

As someone with an HP 1660cs, I'd love to see it. Do you remember the specific architecture it was for? Also, isn't 1650 software compatible with the 1660? :) Finally, is there anything I should do with my 1660cs for preservation purposes? Image the hard disk, that sort of thing? Or can it be

I've been looking for an SS-30 bus floppy controller for some time now. Examples would be DC2/DC3/DC4/DC5, but I would also be OK with a Pertec or SSB. Anyone have one that they would be willing to part with?
