I have.  The microcode listings aren't.  They're octal dumps.  Which
is fun to type in, I'm sure.  They look OCRable for anyone trying to
disassemble them, btw...

Actually you could probably recreate nearly all of the 3600 using just
the patent.  It's that detailed.  I have a printout of it that weighs
a few pounds.  It has all the sources you need to get booting, I
think.

What I'd kill for is a similar document for the Explorer.  But
unfortunately TI wasn't silly enough to patent their entire machine,
just some interesting parts of it, mostly hardware.

In order to save Just A Few More Bytes Of Space I recompressed it with
bzip2 instead of gzip.  This also to annoy people with a longer
decompression time... :-)
