+
+  TeleVideo 990 terminal
+  
+  Preliminary driver by R. Belmont
+  
+  H/W:
+  68000-P16 CPU (clock unknown, above 10 MHz it outruns the AT keyboard controller)
+  16C452 dual 16450 (PC/AT standard) UART + PC-compatible Centronics
+  AMI MEGA-KBD-H-Q PS/2 keyboard interface
+  Televideo ASIC marked "134446-00 TVI1111-0 427"
+  3x AS7C256 (32K x 8 SRAM)
+  
+  IRQs:
+  2 = PS/2 keyboard
+  3 = Centronics
+  4 = UART 1
+  5 = UART 0
+  6 = VBL (9003b is status, write 3 to 9003b to reset
+
+  Video modes include 80 or 132 wide by 24, 25, 42, 43, 48, or 49 lines high plus an
+                      optional status bar
+  Modes include TeleVideo 990, 950, and 955, Wyse WY-60, WY-150/120/50+/50, ANSI, 
+                      DEC VT320/220, VT100/52, SCO Console, and PC TERM.
+
+  ASIC registers:
+  0x01 = possibly width (80 written at startup)
+  0x09 = possibly height (50 written at startup; 49 + the status bar)
+  0x16 = cursor X position
+  
+  Status bar is out of the way of used VRAM at offset 0x36b0.
