I have the 386sx variant of this. Things to like are the standard AT power connectors on the board, it uses a coin battery and 72-pin simms. Graphics are cirrus logic.
All that makes it a very easy machine to work with. Will make a great little DOS machine for you I'm sure. I'm very fond of mine.
Best,

Found the IBM datasheets on it. Looks like a nice little machine the only question is can I get it working. The lister doesn't seem highly knowledgable on the matter so many it's something simple.

In one of the pics it looks like the power button is stuck in, might be as simple as that!

We had these exact boxes in school in 1997-ish (yes, 1997...) If I recall correctly they were 486SX/25 systems, they had either 4 or 8 MB of RAM and 127 MB hard drives I believe. We used them with Windows 3.1, Netware, Netscape 2.02 (which was like watching poorly rendered molasses), Office 6 and whatnot. They were rather loathed by everyone since they were s-l-ooo-w on the web -- the computer lab upstairs had Pentium ][ machines 😉

They are solid enough I guess, utilitarian as hell. Nothing fancy design-wise or hardware-wise -- more like the bare minimum of everything, hence the Value in ValuePoint -- but on the plus side, really rugged build quality as was IBM's usual modus operandi. And much less annoying proprietary stuff to deal with than, say, a PS/2.

Look forward to seeing how this turns out.

It hasn't come in yet. I will let everyone know when it does. I am thinking of putting a 486SX2-50 in it for the sake of doing something different. I didn't realize until recently that they made an SX2.

Got the system in today. It powers right up! Has a disk drive error on post but hitting escape it boots right into dos and looks like Windows 3.11 is installed. It's got a weird amount of RAM. It reports 5120k of memory with 3 72pin SIMMs installed. I was hoping to upgrade the processor but the CPU is directly onboard not socketed and I am not that adventurous. It does have a place for a path co-processor and while I doubt I would ever use anything that would benefit from that I might just do it anyway.
