Whats the word on 286 accelerator boards
So I have a IBM PS/2 model 30-286 (whoa! what a surprise ) and I'm looking for options to ditch the 10MHz 286. I've seen some 16-bit ISA cards that are a complete 386-system-in-one, 16-bit ISA cards that are just a 386, and daughterboards that fit into the socket that add a 386SX. Am I limited by compatibility or are all of these viable upgrade paths?
