I still find it hard to belive that PDP-8/a had a math

That does make the PDP-8 the smallest computer with real floating
point I can think of. Ben.
For a math copro to be called as such, does it have to integrate itself with
the CPU's instruction set - or does some sort of box of tricks sitting on an
I/O port and accessed through normal CPU instructions count? I'm not sure what
the correct definition is.
What do you mean by 'smallest computer' by the way? Smallest in terms of spec?
I'm pretty sure some of the 1950's stuff had optional floating point hardware
available, although it wouldn't have been physically small :)
