People have been asking about the memory requirement for Apple Dylan.
I received it in the mail yesterday (yah!) and read the section labeled
"Configuration Requirements". I think it's worth quoting. Any typos are
mine.

"We recommend running Apple Dylan on a 68040 Macintosh with at least 20
megabytes of _physcial_ memory. You can use virtual memory, but if you have
less than 20 megabytes of physical memory, performance may be poor.

"The Apple Dylan development environment requires a memory partition of at
least 14.5MB, with 18MB suggested. A low memory version of Apple Dylan,
"Apple Dylan SI" requires a memory partition of at least 10 MB, with 14MB
suggested. This decrease in memory requirements comes at some cost in
performance...

"The actual amount of memory used by Apple Dylan varies with the operations
being performed. For example, it takes significantly more memory to compile
a project or create a library than to use a library of the same size...

"The Apple Dylan development environment runs best on a 68030 or 68040 based
Macintosh. To run the development environment on a Power Macintosh, you
should turn off the modern memory manager.

"Applications under development can be run on any Macintosh, and will run
native on the PowerPC."

Note: 'SI' stands for Swapping Image--it's a version of Dylan that swaps
things in and out as needed.

It appears that to do anything interesting with Dylan, you also have to run
the "Application Nub". This is for running our program. It has a minimum
size of 550K, and a suggested size of 20M.

In short, you need loads of memory.
