  I am planing to buy a 386-system and have something not clear. I'd apologize
if these questions are easy or often asked or silly.
  
  1  Can a 386-33 system (or 386-25) run the old programs designed for 8088? 
for 80286? They said a 386-SX can do it but SX is too slow.
  2  Can a 1024*768 multscan SVGA run the old programs designed for CGA and EGA?On which level is SVGA compatible to EGA?
  3  What does a cache do? Is it really helpful? 
  4  If the computer is used mostly for computer-graphics, is it very important
to buy a 80387? It's expansive you know.
  5  Finally, some non-named machine sells very cheap. I mean,much cheaper than
NORTHGATE, GATEWAY, ZEOS, SWAN, EPSON,... is it reliable? Can I trust them?
  So the basic problem is that I have lots of old software for 8088, and I don'tseem to have much money to buy those 386-software. The compatiblity to 8088 is
the bigest question to me. 

  Any help by e-mail or by news is appreciated. Thanks a lot.
