Today I was at talking to someone who still had a 486 in a corner of his office. He claimed it should still be running even though he had not touched in at least 10 years. So I pressed the power button, and it booted up fine, straight to the windows 95 Desktop. He was so kind to give it to me, as long as I destroyed and returned the harddisk, and I am supposed to take the yellowed screen and keyboard too.
It has been like 10 years since I touched a system this old myself, so I am still trying to figure out what I am dealing with here. Unfortunately I don't have much time now.
EDIT: updated the info below
Case: Baby AT with a 'Target' case sticker. A 200W 'Target' PSU is at the bottom and the VLB slots are at the top. Assembled Week 2 1995.
CPU: Cyrix Cx486 DX2v66. Set to 3,45 Volt. No heatsink or fan.
Motherboard: TK 8498F /GP 4N D24, Socket 3, UMC UM8498F Chipset. 4xISA, 3xVLB. 256kB cache. AMI WinBIOS 1993. PCB week 46 1994.
VLB Multi-IO+VGA+IDE: UM-85C418 'Super VGA', 1MB 80ns, VESA 1.2a, max 1024x768x8 / 800x600x16 / 640x480x24. PCB week 28 1994.
Memory: 2x 4MB 72-Pin 70ns. Four 30-pin slots still empty.
Sound: ISA Aztech Waverider32, with 2MB Wavefront Wavetable, OPL3 and CD+IDE interfaces. PCB week 38 1994.
Modem: ISA 14k4, Rockwell.
Harddisk: Conner 94112-042, 420MB, 3.5" IDE, Type 47.
Removables: Floppy 3,5". CD-ROM 48x (connected to sound card), Tape streamer 'Colorado 250MB' (as floppy slave).

I do have an Enhanced Am486 DX4-100 chip in my drawer, I suppose I could install that one too. Is that without jumper changes and does it work well without a heatsink? What are these LED jumpers for?
