This PS2-to-USB single port adapter is designed specifically to convert a BigKeys keyboard to a USB port. The adapter accommodates the special BigKeys "no run-on" feature, which is defeated by use of a generic USB adapter. For Windows 98 (& newer) operating systems. Also for iMac or other USB-enabled Mac computers. If you are ordering this adapter for an older BigKeys keyboard that you already own: this adapter is only for use with BigKeys manufactured in 2004 or later.
