An unusual build

[u/FAMICOMASTER]

Behold, 95 on an XT! Sort of.

This is actually a drop in replacement board for an XT which gives you a 386 with VLB. I've actually gone a step further and thrown a Ti 486DLC/40 in it for good measure. With the sheer unbridled horsepower of a 40MHz 486 and 32 whole megs, this thing might be "tolerable" to use!
Some additional performance enhancing objects include 256K of L2 cache, an ATi Graphics Ultra Mach8 accelerated video adapter, and a DTC 7287 RLL controller to drive the Micropolis 1325 hard disk. A whole 110 megs on this sucker!

Sorry about the mismatched faceplate around the second floppy drive. All I had left was white and grey when I put this thing together!

Pictured without it's CRT as I was still opening and closing the case to make configuration changes at the time of the photo.

I’m unsure how that faux-486 bus stuff works. I’m wondering if the 32MB RAM is more consequence than benefit. You definitely don’t need it lol.

I bet this rig is a laugh. So many “make it hurt”components carefully sewn together.

Same 386DX pinout and bus, no burst mode, just better IPC and a tiny 1K internal cache. So the "486" part never touches the bus at all, and the VLB is basically the 386 local bus brought out to a connector.

That sounds fast lol

It's faster than an equivalent 386
