bakis,
whether perfectly square or a pulse shouldn`t matter, i would think, as the 
circuitry should fire on the leading edge.
i recall that the a115 audio divider was picky about the a111 pulse output, 
too.
weirder..........
best,
dave

yes, as well as the A113..

luckily i discovered this before buying a111s.  no probs w AS 
vcos, everything tracks the pulse very well, including 155 as 
graphic vco.  (and i think dieter's estimate of 10kHz ceiling is 
accurate)

to switch gears real quick, i agree w joe on his argument for 
need for improvements, and the a111 pulse output would be a 
good place to start.

hi dave,


roland mayer once told me that for the a155 clock
input to work right needs a perfect pulse with sharp
sguare egdes....
i guess that explains it all....
