begging drivers/docs for obscure old PC/Mac hardware

I actually have an old MacUser or Macworld magazine that briefly mentions
the MacBlitz just in the context of some silly article where they tried to
build the most expensive Mac system possible by fitting all these obscure
and expensive options... it might quote a list price (if you were curious?)
but beyond that, your description here was more revealing than anything
they wrote in Macworld or MacUser.

It's very interesting to hear that the board was based on the Clipper CPU,
of all things. I wonder if it ran as a stand-alone computer with a separate
operating system image (like a MacIvory, or an Orange Micro card) or if it
was just used as an applications accelerator like those NuBus DSP cards
they used to sell. Even in lieu of any software, I think the board will
make a neat little piece of RISC ephemera. I used to have a few Intergraph
2400 systems myself... wish I had saved a CPU module before they got
binned. You don't see many examples of the Clipper around anymore.
