I got to write code for the  Burroughs 1900, a successor. The code
density was about 10 times what I was used to. I loved the machine,
but it was not that much fun to code since everything was done at a
high level language level.   It was just so straightforward. The thing
I found most fun was NCP language.  Even a salesman could write a
custom program for polling a set of multi-drop terminals.

The underlying hardware had only 24 bits addressing, but it was bit
addressable. That let you address bytes with 21 bits, a mere 2
megabytes.Yet that little machine pumped out transactions like you
would not believe.  It used memory very cleverly dynamically balancing
system, app, database, disk cache.

I suppose they could have extended the architecture, leaving the
per-process limits in place. Univac and Burroughs merged to form
UniSys.  I don't know what happened to their various architectures.  

Univac had the 1100 36 bit machines, and some mid range IBM
compatibles inherited from RCA. Burroughs had the high end Algol
machines (fiendishly complex), mid range decimal addressed (designed
for easy assembler coding) and the 1900 series -- the interpreter per
language design.

Why do so many operating systems refuse to define a standard 
temporary file marking mechanism? It could be a reserved lead character
such as the ~ or a reserved extension such as .tmp.
It could be a file attribute bit. Because they refuse, there is no 
fool-proof way to scan a disk for orphaned temporary files and delete them. 
Further, you can't tell where the orhaned files ame from. 
This means the hard disks gradually fill up with garbage.
