Ti microExplorer

Hi: I've been collecting Lisp items for several years now; I had acquired a Symbolics MacIvory through the 'usual channels' as well as a TI microExplorer that took years to assemble. When I moved a couple of years ago, I didn't realize that the microExplorer had suffered a fatal injury, until I attempted to power it up at the request of someone interested in it. As most of the 'old Lisp' mailing lists are more-or-less defunct, and the current generation of Lisp enthusiasts appear to be focussed on software-only systems, I'm hoping that someone on this list knows where it might be possible to get boards for the TI microExplorer or, hopefully, has one that they'd be interested in making available. I realize that this is quite a long shot, as the system was developed in the lat '80s and didn't see a lot of sales. [I'd even be happy with a second MacIvory, if someone was willing to part with it...]
