Yup! That's the puppy! Mine's in an AMD 5x86P75, though. 😜 In a small-form-factor desktop, even. From the labels, it was obviously meant to be pretty much a "thin client". 486 socket, two 72-pin SIMMs, onboard CL-GD5430 VGA, three ISA slots on a riser. Right now, I have a generic NE2000 card plus a Microsoft Windows Sound System in it. I had my prototype SB in it for awhile, but I just got a PS/2 Model 25 that I put it in. (Unfortunately, the PS/2 appears to be dead, so I'll be pulling the card back out.)
This chassis has one internal and one external 3.5" bay. My dual drive is used with the chassis lid off, and the dual drive sitting above the 3.5" bay on top. I think I'll try to hack together an external case for it when I get a replacement, and just use a really long ribbon cable going through the empty card slot to the onboard floppy port. Maybe I'll recycle an old SCSI CD-ROM case.
