    DATA SWITCHES:-

	000 000|000 011|111 111|112 222|222 222|333 333
	012 345|678 901|234 567|890 123|456 789|012 345
	hf- ix-|--e|qsr|pad OOO|III PPP|AAA DDD|TTT TTT

	At least one T switch (30-35) must be ON to enable the actions below.

	Setting T to zero will load the default settings (see DSDEF below).

	Any enabled switch state-change will result in all lamp pattern cycles
	being reset to their initial states with the new settings.

    Action if DATA SWITCH is ON:-

	   00  (h)  HALT before starting the next TICK (to learn how it works)
	   01  (f)  Select FAST CPU mode (slows the TICKs by 32x)
	   02  (-)  Reserved

	   03  (i)  Turn off INDIRECT mode in the TICK loop instruction
	   04  (x)  Turn off INDEXED AC in the TICK loop instruction
	   05  (-)  Reserved

	   06  (-)  Reserved
	   07  (-)  Reserved
	   08  (e)  Set PCNT equal to ADDR (ignore the PCNT table)

	   09  (q)  Set DATA equal to ADDR (ignore the DATA table)
	   10  (s)  Swap the DATA RHS with LHS
	   11  (r)  Set the DATA RHS to the same as LHS

	   12  (p)  Complement PCNT lamps
	   13  (a)  Complement ADDR lamps
	   14  (d)  Complement DATA lamps

	15-17  (O)  Pattern offset (0-7) [7=1KW memory]
	18-20  (I)  INST speed relative to T
	21-23  (P)  PCNT speed relative to T
	24-26  (A)  ADDR speed relative to T
	27-29  (D)  DATA speed relative to T
	30-35  (T)  TICK speed (basic time unit ~1/63s)

	UBITS = 116000000000 (see DSOFF for when to use UBITS)

 Suggestion:-

       Start with all switches OFF then turn ON switch 35 followed by 34, 33,
       32, 31, and 30 until you find a comfortable pattern rotation speed.
       Then play with the other switches.
