Interesting: somewhere between  1982 - 88  I sat down with a bunch of
hardware geeks who where looking at a way of exploiting a highly
parallel design (multicore RISC) they had come up with and suggesting
they do hardware/microcode based tree manipulation. (Never went
anywhere, but I still have the notebooks in a closet.)  At the time I
hadn't been able to come up with any other hardware based data
management, but then again, I was only peripherally aware of the
Microdata.  How is that you stumbled across it?
