 Some additional observations:
 
-- During the NVR test, a "WAIT" message is displayed in the top-left corner of the screen.
-- Following the NVR test, code at 0x00D2 loops for 0xFFF (4095) times with the CLICK bit (0x80) set in the keyboard STATUS

+- During the NVR test, a "WAIT" message is displayed in the top-left corner of the screen; it's cleared after the test.
+- Following the NVR test, if an error was detected, code at 0x00D2 loops for 0xFFF (4095) times with the CLICK bit (0x80)
+set in the keyboard STATUS port (0x82), generating a "bell" (beep).  The NVR checksum test used to fail when we initialized all
+NVR words with the freshly-erased value of 0x3fff; now we initialize them with canned values (see ChipSet.VT100.INIT).
