Reply 60 of 80, by 386SX
What a great computer the Presario 433/425. A friend had it and we played the game Stunts on it million times when I had the 386SX20 and I couldn't run it full detail and smooth fps. Not for the cpu but probably for the OTi37C vga I think to remember, the difference from my 386SX and its 486SX was like night and day.
That Compaq I suppose had a S3 805 VLB on board (or a Cirrus Logic can't remember) and that was the great boost but I was convinced that its 4MB of ram was the reason of that so we upgraded to 4MB even my 386 (the max the mainboard could support) and nothing changed obviously, beside Win 3.1. I wasn't a video card "expert" in the 1994 and I didn't even know how much faster that config was compared to the cheap low end of my 386 based one. 😀
Much later I found the very same Compaq used but the more you open the mainboard the more you can break something of the case considering the force to use to correctly close the back part. Also I wouldn't try too many different rams, at the end my pc died for unknown reason upgrading it.
Anyway I remember having used a 486 Overdrive 66Mhz on it easily, ram up to 20MB, network card..Sometime I hope to find another one again.
