i need some friendly advice, or at least reassurnace that my current plans
are safe and sane.  my current system :generic 286 clone, ega card,
original nec multi-sync, rrl controller and 30mb hd.  while i would love
turning it into a second machine, my wife is funny about money matters.  my
plan: getting an "upgradeable" 386-33 or 386-40 motherboard, an 800x600 vga
card and necessary adapter cable.
 
questions: nec says this venerable monitor should support this video mode,
even though it is only speced to 560.  any experience out there with this? 

 next question: some of the new motherboards make the claim that i can pull
the 386 and replace it with a 486 when prices come down (like after the
pentium or 586 is released).  is this accurate?  i know the "upgradeable"
motherboArds that required daughterboards were bogus, but this solution
seems reasonable.  any ideas???
 
final question:sure, i want a big hard disk (and my wife might appreciate
it, too!!nudge, nudge, wink,wink), but my budget precludes the move to a
big ide now.  can i successfully Stack my old yet trustworthy 30mb seagate
in the setup i am describing???  i know it won't be a speed demon, but it
will hopefully meet my needs for a while.

thanks to one and all for your kind and generous advice on this.  also, it
seems this must be a problem others might have...any good articles in any
of the magazines about such at-class upgrades???
