The current ELECTRONICS claims that the new Tandy computer will be 68000-
based, and be out in Feb or March 1982.

Re the Smalltalk kernel in C: I would guess the current kernel is
about 70% relatively environment-independent and 30%
environment-dependent. However, there is another important point: the
Smalltalk system includes its own instruction set, and the 70%
includes the emulator for it. If you are going to run native machine
instructions rather than the Smalltalk bytecodes, you will have to
write your own compiler and decompiler, and do some careful thinking
about how to retain the current pleasant properties of reasonably
direct mapping between the source and object codes. For example, with
the Smalltalk instruction set, the debugger can highlight the exact
spot in a procedure being executed.
Smalltalk is set up so that you can take any procedure whatever and
recode it in an underlying instruction set without any change to its
callers or the system structure. For this kind of thing, having C
underneath would work just fine.

Last year Mike Hammer of MIT was consulting with the OA group
at EXXON. I believe he was involved in designing a database for
integrating office functions. A student of his, Tim Anderson, was
to be working on an editor/word processor function for the same
project, but last i heard Tim was choosing another thesis, so the
whole thing may have fallen through. Anywho, it is a possibility
that EXXON is actually trying to do something major here.

I have a reference to a book entitled Interactive Programming
Environments, edited by E. Sandewall, H. Shrobe, and D. Barstow.
I picked it up from somewhere (perhaps fa.works) about two weeks
ago. I recorded that it was published by McGraw-Hill, but they
don't know anything about it. If you know who has or will
publish this book, please let me know.

It's pretty worthless. That is to say, we don't like it because it
doesn't compile Mince (our ersatz EMACS) at all. For $695, who can
afford to NOT use the Whitesmith's C compiler? (Both DECUS and
Whitesmith's run under RT, RSX, and RSTS.)
