You are probably going to find that most 8-bit processors will adapt
easily to IEEE-695... however there may be some problems with
bit-oriented architectures like the 8051 bit accessible memory. The
primary problem with this format is that it doesn't readily lend
itself to segmented architectures like the x86 in real mode, or the
C167. Although I think the HP version of the format *may* have taken
this into account.

I think this format is in general both more verbose and simpler than
other formats and would readily lend itself to translation into other
formats, as long as you didn't go hog-wild using various features of
the format that just nothing else supports.

I haven't heard of any breakdown of which architectures use which
formats. You would have to contact emulator/simulator vendors for
your architecture to see what they support.
