Anyone know what these are from
http://www.ebay.com/itm/150407824254 ?
It looks like a Motorola 88000 based cpu board. I was able to find
some mentions of a few 88000 floating point boards for use in MicroVAX
II but, can't find anything about Avalon A7Q. If these were
replacement cpu what did they run ?
Avalon sold math and especially FFT/image/convolution/deconvultuionco-processors in the
late 80's and 90's. Used in (among other things I'm sure) medical imaging
back-projectors. "Back-projector" seems to mean something different today in
google searches... back in the 80's and 90's we called the processing system that
takes raw data from CAT scanners and turns it into a image, "convolvers" and
"back projectors".
For a while in the early 90's, the same generation Avalon co-processor was available
in Unibus, Q-bus, and Turbochannel all at the same time. I remember I could get a Alpha
processor on a Unibus card at one point!
For a while (again mid-90's?), I think one company that sold Avalon boards used the
name "teraflop.com". e.g.

This (from the mid-90's) discusses some of the history of Avalon from a typical
number-cruncher's perspective:
