Metal Limit runs on harddisk as well, AFAIK it needs only 128k, but maybe indeed also 32k extra for DOS2.
UR needs 256k *without* DOS2, so, with DOS2 the 32k extra.
Thanks guys !
I've installed these two powerfull demos and all works GREAT !!!
It's a pleasure !!!
I've just need to use chgcpu.com & mapper.com for 100% working ;-)
