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? -- Peter Hunsberger
