Hi Jimmy,

All of the ATA133/100 drives/controllers are backward compatible to ATA33.
The first accelerated controller card I ever had was a Promise 2300 Plus 
on a 486 VLB machine - compared with the onboard
controller there was about a 100 improvement with a Quantum Fireball 
1080 - 1GB drive, far superior! The difference was very visual.
I had intended a couple of years ago to get one of the then current 
Promise controllers, like a TX100 or so, but never got around to it yet.

It's amazing what an older computer with a fast disk system in 
conjunction with a decent amount of RAM and a reasonable video card can 
appear to be - especially with OS/2-eCS!
