Up for buy it now is a NEW 6 pin SDL to USB cable for use with IBM / Lexmark / Unicomp Model M keyboards.  Each lot is for a single cable shown.  They are 6ft in length and are made of shielded stranded cable.  Each cable is fully tested with my IBM Model M keyboard and is guaranteed to perform flawlessly.  

I can make the cables shorter at no additional charge (just message me after purchase with the desired length).

The PS2 to USB conversion circuit is contained within the USB plug's plastic molding and supports the FULL PS2 protocol as defined by IBM (the creators of that protocol).  It does not drop data, does not require drivers, and does not timeout after periods of inactivity.  I've personally tested these cables to work with MacOS X, Windows 2000/ME, Windows XP, Windows Vista, Windows 7, Windows 8, and recent versions of Linux and Unix.  If you have any doubts about it being able to handle certain key combinations where other PS2 to USB converters you've tried have failed, send me a message and I can test it with my IBM type M keyboard to confirm that it will work.  

I will accept returns within 30 days if you are unsatisfied for ANY reason.  Shipping will be free by USPS First Class Mail.  International shipping cost is determined by ebay's shipping calculator based on location and does not include any international taxes imposed by the buyer's country (if charged, these taxes are to be paid by the buyer upon receipt).

 Please contact me if you'd like to buy in bulk at discounted prices or if you'd like custom cables made with 6 pin SDL connectors!

Thanks for looking and please ask any questions you may have!
