BigKeys Keyguards are made of clear, rigid, break resistant plastic.

BigKeys to USB Single Port Adapter (PS2-to-USB) (Part Number USB-BK)

This PS2-to-USB single port adapter is custom 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.

NOTE: Standard adapters will not permit the BigKeys Keyboard to function properly (click here for an explanation).

ADDITIONAL NOTE: 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. Check that your BigKeys has a Serial Number ending in 04 or greater. (SN xx04 means manufactured in 2004).
