Thanks for the information! Just looking at the papers about it I had
the impression that it would be reasonably faster than an ARM at the
same clock frequency while having a VAX-like code density. I was going
to suggest that implementing CRISP on an FPGA could be an interesting
project for one of the grad students at my university, but that doesn't
seem to be the case.

A rather different processor for running C (for floating point intensive
code) was the WM architecture:

I only heard about it because it was the inspiration for the memory
interface in the version of Chuck Thacker's Tiny Computer used in the
Beehive multicore project. This, unfortunately, is probably too complex
for a student in my group.

I know that Bill was the developer, but had the impression that Larry
had done what was needed to move from project to product. He certainly
was the one promoting it pre-launch in the old Smalltalk forums at BIX
(Byte Information eXchange).

2015 is almost here - time to move to the "computer in glasses" model
(lame "Back to the Future" reference, but I know you will agree).

I was thinking about about the LDT and GDT (Local Descriptor Table and
Global Descriptor Table). These still work, of course, but the current
implementations are so bad that it is faster to do the same thing 100%
in software. You do lose the security aspect, however.

It is funny that the wish to put the TSS to good use was the big
motivation for Linux. The resulting non portability (which is a lot less
important now than then) was one of the main complaints in Andrew
Tanenbaum's famous early rant about the OS. The first attempt to port
Linux (to the Alpha, if I remember correctly) required completely
rewriting that part and the changes were quickly brought back to the
Intel version.

Thanks for the tip! I see your description is "Use the Postscript(tm)
language to express your ideas and see the results on your iPhone.
Transfer your creations to your computer via iTunes sharing as either
PNG or Postscript documents."

It is likely that the reviewers considered that "Postscript documents"
means a text file (like a .pdf or .doc). The user who gave you a bad
review certainly did (another user corrected him/her). So this doesn't
tell us what Apple would do with a language that allows you to share
