[time-nuts] OT Systron-Donner Basic

I found a little snippet for the SD-3250 in a synthesizer manual:

1) BUS CLR Return			# Prepare controller for Bus operation
2) BUS REM Return			# Clear the bus and command 1702 to operate
3) BUS OUT GO256540 Return		# Set frequency to 25.654 MHz.
4) BUS OUT GO256000 or C000 Return	# Change frequency to 25.6MHz, 2 methods
5) BUS OUT L0555 or L3355 Return	# set level to -25.5 dBm, 2 methods
6) BUS OUT MO Return			# Select AM mode
7) BUS IN A Return Print A Return	# Check operating status

Comments were added by me, and there is no indication that "#" is a valid
comment indicator.

So, basically, it looks a bit cruder than even BASIC.
