I ran it in the original box and tried it in the box housing the MacIvory; I haven't
tried removing the memory piggy back card - when it powers up, a single red LED is on and
the Macintosh microExplorer software reports a failure to connect.
I'm several miles away from the system right now, but I can gather some more detailed
information later this afternoon.

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.

Does it have the memory piggy back card? If it does, did you try running it without it?
Are you running it in the same Mac that you originally ran it on? They are pretty picky
about what they will work in.
