The drawback of the light chaser program that uses the RESET instruction
is that the heads load and unload of the RX02 drive in my PDP-11/40.
Correct. The Bus INIT-L signal causes that.
But I wrote that program for my 11/45 long before I had any peripherals
connected -- in fact long before I had any peripherals at all, even a
DL11. So it wasn't a problem for me.
