If so was there any real improvement in performance? It works. As can be expected the performance is better than a 386 and worse than a 486. >Also, besides the 486DLC missing the math coprocessor, what are >the differences between the Cyrix & Intel parts?

The prefetch queue might work differently so automatic single-stepping might not work the same, the Cyrix part only has 1kB of onchip cache but claims faster integer arithmetic. 486 code runs fine so long as there is a coprocessor. There are bound to be other differences, these are probably the main ones. -- adam@veda.is
