I think your memory of memory is fine. :-) The original version of Janus/Ada 
worked fine on a 48K Z-80 machine (just a subset of Ada, though).

The first validated (Ada 83) version was for original 640K IBM PCs. Even 
today, the memory footprint of Janus/Ada never exceeds 16Mb.

Claw programs are "huge" by our standards, but they too tend to have a 
footprint in the 16Mb range. So 256MB would be plenty for program 
development (depending on the OS size; we might only use 32MB but Windows of 
course uses a heck of a lot more).

                                          Randy.
