A BIOS upgrade was chancy, and would cost $ 100. So I opted for a new motherboard, a 386-33. My memory and math co-processor were adequate already. The total upgrade cost was $ 185. And I can use the old board to upgrade a '286. I'll bet my total cost for the two boards over the 4 years or so was well below the cost of a premium board back then (which would be obsolete technology by now). For the same reason, I wouldn't pay more than $ 100 or so premium for an "upgradeable CPU" motherboard. Bare '486 boards (no memory or CPU) are only $ 120 now. If it turns out I have to upgrade the BIOS or CPU a couple of years down the line, it almost certainly won't cost more than that. -- Mike Berger Internet berger@atropa.stat.uiuc.edu
