Hello, I have recently rebuilt my 486 gaming system, due to the unfortunate tragic death a leaking CMOS battery had caused my previous motherboard, and everything's going great so far! Except, I've been considering putting one of my 3Com EtherLink 3C509B-TPO adapters in, but I just can't find drivers, or at least the right drivers online for these. Everything I've come up says Windows 95, 98, 2000, and even XP. I'm wanting drivers for MS-DOS and possibly Windows 3.1 (or 3.11).

I checked out the Vogons' driver data base, and came up empty handed for anything network related, but it was super nice for the GPU drivers! 😀

I've been curious about Descent's networking ability as well, between machines. 😀

Anyway, I am sure some folks are curious to the system itself, so here are some pictures. 😁


System Specifications:
AMD 486 DX4 at 100MHz
ELITEGROUP COMPUTER SYSTEMS, INC. UM8810P-AIO motherboard (Capable of 128MB of RAM, max!)
64MB DRAM + 256K Cache
S3 Trio64 86C764 PCI Graphics card. Not sure on VRAM amount.
3DFX Voodoo 2 3D Acceleration Card
Sound Blaster AWE64 Gold with Add-On SIMMConn Memory Adapter expanding the audio RAM up to 28MB!
2GB Transcend Compact Flash Card in place of a Harddrive, using a Syba Compact Flash to IDE adapter, that mounts in the rear brackets.
Memorex 52x CD-ROM/CD-RW Optical Drive.
3.5″ 1.44MB Floppy Disk Drive.
5.25″ 1.2MB Floppy Disk Drive.
MS-DOS 6.22 and Windows 3.1 with all the appropriate drivers installed.

Go here. The file you need is 3C5X9X.EXE. That's got the WIN31 and DOS drivers, as well as the config utility.

Edit: Holy crap, I just noticed in the pictures... you're using an SX-1980 for computer sound? 🤣

Ah, awesome, thank you so very much for the link! I'll try it as soon as I get home!

Yep! Pioneer SX-1980, fully serviced! Here's an older picture of it when it was in my main sound system:

This isn't the only silver-faced beauty I own, either. 😁


Ah, the driver worked wonderfully! Thanks again!

Here I got the 3Com installed, above the AWE64 Gold, and since the card isn't wide, it fits and clears the SimmConn add-in memory module!

So to test 'er out, I fired up Descent to try out, networking from DOSBOX to the 486. 😁

I have a VRM installed, but you can't see it well since it is hiding just under the 3.5" bay. Behind the 4 pin molex connector on the first picture above, in my original post.

Here's a picture of the board with the VRM installed, outside of the case. 😉


If you'd like, I could pull the VRM and take a picture of, if you want to see the other side of it.
