This is my first post.

So I acquired an Acer acros 486dx33 computer used recently. It's got a1g 93113-2 motherboard in it with 28 megs of ram in it. My three questions are is it's got a 4isa riser card installed in it, is it possible to replace that card with one that has PCI on it as well? Also the spec sheet I can find online lists dx4 100mhz as the best chip it can handle. I'm curious if any of the AMD 120mhz or 133mhz 486 X5 chips would work on it? Lastly is the btc 1853l sound card any good? My goal is to use it as a windows 95/dos gaming machine eventually get a mpu card and hook up a mt-32, sc-55 (or maybe 88).
