Hello. I'm new to your board, and I have a question?
We purchased a vintage Williams engine identified on the box as "GP525 Burlington GP9 Power A W/Horn CAB # 2329". This engine was purchased for use in a children's museum where I do volunteer work. It's essential that we lock the engine in forward.
I have modified a few Rev. 4 circuit boards to lock the engine in forward, but, even though one of the boards in this engine looks very much like a Rev. 4 board, the same mod doesn't do anything. The board is identified as a 247 Category 1 reversing board, Patent # 5,321,344, and 335-X001R2. This appears to be an engine from the early 1990's when locking into a direction may not have even been discussed.
Would anyone know if this engine can in fact be modified to lock it into forward?
Thanks for any help.
Joe
