> p.s. @ dieter: how about a bus connection on the 161 for a second 161

running from the same 160

That's easy. You simple need a 10 pin cable with 3 female connectors (one
for the A-160, one for A-161 #1 and one for A-161 #2).

But I cannot see an application for this purpose. The outputs of the second
A-161 would be a 1:1 copy of the first one unless you use different clocks
or resets for the two units. But this requires some DIY as mentioned in one
of my former messages.

Best wishes
