Lexmark M13 NIB - $100

[JP]

You don't see NIB very often at this price. It does use an oddball serial connector for the mouse though.

I saw this earlier today on reddit.  So, would one of these dudes work?

Also, I realize that NIB still could have almost every rivet broken when I get it.  But it's so pretty

I think you would need no less than 3 adapters. 1st a din to PS2 adapter, a DB9 to PS2 adapter, for the mouse and finally an active PS2 to USB converter with mouse and keyboard. I think this setup will work.

I am thinking something like this would work for the mouse part.

For the keyboard:

A bunch of adapters...or use it with an old school PC since it comes with a floppy which I assume contains the mouse driver.

Gotcha.  I think you linked the wrong male/femal version of the 5pin to ps2, but I have one already.  I'll have to think on it.

I'll have to think on it.

While you think on it I'll find something else interesting for sale to post here

Nonetheless, this is an excellent price for one of these NIB... I don't think there's any reason not to find it interesting!
