I ran across an old XT clone with bus board in it

ever seen had an actual motherboard. I just thought this was an
interesting machine. I have some pictures of it -

about this? Were there other PC's made like this?
My guess is that it's a a Zenith, even though, I can't see it yet. I
think these computers were built for the government. At least the later
386 versions..... supposedly they were built to fall off a moving truck.
Might be urban legend, Though.
I know Zenith made XT's and 286 systems with that design, I've seen too
many of them go through Purdue's surplus lately. However, that DEFINATELY
doesn't appear to be a Zenith machine - the zenith machines I've seen are
much wider and generally bulky (at least as wide as a PC/XT/AT case, and
deeper - I noticed that when I tried putting a CGA card from one into a
PC/XT and it didn't fit :).
Of course, there are also newer machines with passive backplanes, I think
JDR microdevices has sold 'the parts' for ISA and PCI (PIC/MG?) passive
backplane machines.
