Look on page 3 of Appendix H to the Hardware Reference manual.
Briefly, though, it says:

   One blink      Keyboard ROM test failed
   Two blinks     Keyboard RAM test failed
   Three blinks   Watchdog timer test failed
   Four blinks    A short exists between two row lines
                  or one of the seven special control keys.

It also says that you probably would not have been able to type anything
before this sequence would be completed, but if so, the key codes
would be sent to the computer and then a "terminate key stream" code
would be sent.  There is more information in that appendix.
