Program: AccessDOS is a public domain TSR developed at The Trace Research and
     Development Center which provides extensions for keyboard, mouse,
     and sound access by the visually, hearing, or motor-control
     impaired.

Note:  INT 60 is the default vector; AccessDOS will use the first 0000h:0000h
     vector in the range 60h through 66h.
