- Look at the mac, you can turn off the feature. I'm not a mac axpert

- enable VM... Now they are regulare user / programmer.
- Under system 7.x you can actualy work with 16meg and no VM,
- under windows95, I have 16 meg, and tryed to run without VM... I
- couldn't do ANYTHING in 16meg... Cant even load the C environment.
- My guess is that you need 8meg just to boot windows, and BTW my
- w95 system use an 8bit 640x480 display and tiny icons.
-
- I think AT can make a system that actually boot/work with 4meg and
- without VM enabled... but VM is their for user to enable.
