[comp.sys.m6809] Out of memory...

klieb@uicsl.UUCP (05/22/87)

Actually, it's not that hard to run out of ram, even with 512k on a QT
(also known as a Uniquad). I used to get squeezed pretty regularly, so
I bought the 1 meg upgrade eventually. I only ran into problems when I
was doing development in C.

The problem is that one would like to have a ramdisk to keep standard
include files and compiler temporaries in. After some experimentation I
found that the include files would fit in a 128k ramdisk, but just barely.
If you want to use -t=/dd to put temporaries on the ram disk you have to
go to the next size up, or 256k of ram disk. So far, so good. The C
compiler will work with just 256k of non-ramdisk without problems, but
you run into problems if you attempt to use MAKE to automate your re-
compiles. Out of memory... If only there was a 192k ramdisk...

Regarding editors and memory, some of you folks might be interested in
looking up Ed Ream's article on RED, his editor, in Dr. Dobb's Journal
circa 1983. He discusses some strategies and tradeoffs in the design of
virtual memory editors.
