Not sure of this but will 64K be enough RAM to
work with a hard drive ? I
believe Dos 2.x was the first that supported hard drives, dunno what it's
minimum RAM requirement is tho.
I know it boots DOS 2.11, so maybe this is enough. I'm keeping an eye out for a memory expansion card
as well. 256K
should be enough for anyone, right? :-)
640K acording to Mr Gates.....
Actually I'm supprised no one has made an XT type card that has a single
1M SIMM mounted on it to expand the memory to 640K, should be pretty
easy to do as most simms will self refresh if you reverse the order of
RAS and CAS once in a while. I know this is at least in theory possible,
as I have hooked a 1M simm up to a Dragon 32 (UK CoCo clone) in this way.
Cheers.
Phill.
