Hi,

  is it possible to mod an A-155 to reset to step 8 rather than 1?

Yours Aye

No. A hardware counter (CD4024) is used in the A-155 (no microcontroller)
for address generation. The positive transition at the reset input of this
circuit causes to set all addresses to zero.

circuit causes to set all addresses to zero.

But I can't see a reason to reset to step 8. If you simply "re-define" the
steps in your sequence (1->8, 2->1, 3->2 ...) you are able obtain the same
result. Or did I overlook anything ?

P.S. The A-155 in combination with A-154 has a different behaviour. A reset
signal does not set to step one but only prepares the unit to jump to step
one with the next clock pulse. Maybe this is the behaviour you want to have.

Dieter,

  thank you for your response.  I was indeed looking to have the 155 move to step 1 on 
initiation and I currently manually set it to 8 to achieve this.  I was just curious about a 
labour saving mod.  I quess I'll have to save my pennies to buy an A 154.

Danke,

Stuadh
