Ibm At Keyboard 1390120 (eBay)


If you don't care about lock lights, this is a swell deal on a 1st-generation M. It has the rarer Model-F-style barcode label, which IBM used on some early M's before switching to the simpler M-style labels; and includes the original black AT cable, much less common than the ubiquitous beige PS/2 cables.
It lacks LEDs because it was used with terminal emulators that showed their lock-key status onscreen. However, unlike most other terminal-type Model M's, it can be used with a PC with a simple AT-to-PS/2 adapter (plus an inexpensive cube or cable USB converter, if you wish).
As I post this, it's at $35 plus shipping. For some reason it's hasn't appeared with the regular "ibm keyboard" search results (I spotted a thumbnail of it elsewhere); maybe that's why no one's bid on it. I already have one, or I'd grab it myself!
