I didn't. Thanks.

VMS, that's even supported to some degree in the source tree, and
OS/390 (aka z/OS); patches to support it have been rejected, but
people will likely maintain a fork themselves.

I know two mobile phone platforms for Python: Nokia S60 and Pippy for
Palm. I haven't had time to study Python on
A request for information:
What non IEEE 754 platforms exist that people care about running Python 2.6,
Python 3.0 and higher on?
By non IEEE 754 platform, I mean a platform where either the C double is not
the usual 64-bit IEEE floating-point format, or where the C double is IEEE
format but the p
