I have an AST/286-premium (circa. 1987).  People have told me that a mother-
board swap is impractical/impossible for my case.  (The AST has a non-
standard case??  Looks like a standard AT footprint to me).

How would I go about swapping up to a 386 or 486 motherboard?  I need a 
"checklist" of things to do, pitfalls to avoid.  I have a pretty large
base of installed hardware (modem, video, Perstor controller, two fixed 
drives, floppy, etc., etc.).  Noone will buy this system at any price
near what I would need to recoup to buy a 386, so it looks like I need to
build from what I have.  Help.

Any suggestions on practical "how-to" books on this sort of change would
be appreciated.  I'm certainly unafraid of opening the system up--I do it
all the time to perform routine cleaning, install or modify memory settings,
ad nauseum. . .but I've never swapped my whole motherboard before.

Also, no reason to let the old motherboard go to waste--any ideas on how to
go about selling the motherboard?
