I'm not sure. The Nova certainly used large boards
- 15" * 15"
- and while the original nova (and I believe supernova) and
nova 1200 got by with just one, it the 800 family used two of
those huge things. Since mechanical engineering was never a
strong suit at DG it's generally accepted to use a rubber mallet
or wooden drift to seat those boards into the backplane...
And some of the later DG Nova-descended CPU's (for example, the S/230)
packed an amazing amount of parts on those huge boards!
Were you the one who posted looking for an S/130, Chris? Hate to tell
you this, but I had a half-dozen of 'em two years ago - if you'd only
been reading then!
