So, we have a "standard" which says that both behaviors should be supported, and there should be two different ways to express them, but explicitly declines to say which does what? I'm genuinely not sure what purpose this p

Here's a look at mainframe arcana from the perspective of someone with training only on POSIX/Windows era systems -- COBOL was the easy part. Figuring out how to format the program text and submit it to the compiler took... quite

Immediately after the Oracle/Sun acquisition, there was a huge exodus of senior engineering talent (e.g., most of the core Solaris kernel development team). This writeup of why James Gosling left has some of the obvious reasons (e.g.,

The distinction was slightly more subtle -- "slice-wise" was a storage mode for data in which a 32-bit float would be stored as one bit in the memory of 32 processors, so the "transposers" could be bypassed going in and

The CM-2 also had hardware floating-point units (off-the-shelf chips from Weitek, paired with groups of 32 bit-serial processors, via custom chips with "transposers", which would transpose 32-bit floats read bit-serially out of 32

Not sure what you mean here... Fortran I had a damn good optimizer, and the papers on it introduced a whole lot of terminology (e.g., as above, "basic block") which is still in use. And it was written for the 704, in assembly.

Some of this needs checking -- you could not run Unix on Symbolics hardware. LMI did have machines that ran both OSes -- but Unix was running on a separate 68000 processor; see, e.g. http://www.bitsavers.org/pdf/lmi&#

Non-profits can still have patent portfolios that they try to exploit for commercial gain -- though by licensing, rather than producing products directly. When the research was publicly funded, the same conflicts of interest apply.
