AST Advantage 486 Vintage DOS PC w/ Monitor, Mouse, Keyboard, Speakers

Got everything cleaned up nicely, replaced the battery, and added sound blaster and SCSI support. Had it playing games like Doom and Sam & Max perfectly, but ever since I added the CD-ROM it doesn't seem to want to detect any hard drives (or in my case CF cards on an IDE adapter). It still boots to DOS from floppy, but I can't figure out if it's a settings issue or what. Got other projects I'd like to work on though, so I need to make space. The rubber on the feet also seems to have started breaking down, and I'm afraid I'll just make a mess if I try and clean them up. Could be a good project for another vintage PC nut though. Specs: Intel 486 33mhz 8mb ram (upgradeable to 16mb, but it's proprietary) Creative Sound Blaster 16 Adaptec SCSI controller Onboard VGA/IDE/floppy/PS2 1.44mb floppy drive 4x IBM SCSI CD-ROM 17" CRT monitor, (newer model AST, max 1280x1024 I think?) P.S., I'm definitely open to trade, too, if you've got any old PC hardware or boxed PC games you're interested in offloading.
