- They had those crappy VGA "framebuggers" that were plain evil and awfully slow
- They also made the main MCU used in the infamous Fujitsu MPF/MPG harddrive series... that were bound to rot as soon as they left the factory... and also forcing Fujitsu to exit the desktop HD business
- They also made a couple of Winmodem chipsets
They STILL do exist, making mostly noname audio ICs and some embedded automation shit. Check it out! www.cirrus.com/
I recently got another 486 machine (AST Advantage! 486/33) and it has a Cirrus Logic chipset in it. I maxed out the RAM (32 MB lol) and put a 486 DX/2 66 in it and playing duke on it was pretty meh. I found one of those Intel Overdrive chips and put it in there and it ran much better.
I wonder if I can get Windows XP to run on it since the Overdrive has the two instructions it needs (cmpxchg and cpuid.)
