Hello all this is my first post here. I have an AMI 200 model r-88 juke
box. I cannot get it to take manual selections. I can set it to play
continuously random records no problem.
Any help will be greatly appreciated!

You need to send the following board to be checked by a Rowe Ami
specialist:-
CCC (Central Control Computer)
Pricing Board (just below the CCC)
Mechanism Control Unit (on the mechanism/carousel)
It may be an idea to include the opto switch.
If you were in Europe you could send in the boards for testing/repair.
In the USA Bruce Wentworth is your man.

It is possible that these have appeared elsewhere too, so there might possibly not be a pricing board in the OP's unit.
Thinking back about 13 years or so , I had an AMI R-91 or 2 that often used to "cut out" on the first selection of the day, but not on random play. It turned out to be the magazine motor had a shorted turn, and would heat up, and the thermal cutout would open, if it did more than about 1.5 revolutions. On the early machines, it would find the home position as soon as you turned power on, and this meant usually less than one rotation of the magazine. Any selection made after that would involve less than one rotation too, and the time the record played was sufficient for the motor to cool.
With these later machines, the magazine would find the home position AFTER the first selection was played, then go on to play it. This could result in up to 2 revolutions of the magazine and the motor did not like this and would usually cut out for some time, causing errors, and other weird stuff to happen. Later it would come good of course.
Add to this the fact that in Australia, the mains is 50HZ unlike the 60HZ in the US, the motor took significantly longer to do a complete revolution.
I doubt that there is any gearing change between the 50 and 60HZ motors, as ones that are direct US imports (not made for AUS market) rotate at the same speed as the Aus marketed ones.
The guy did not want to spend money to replace or rewind the motor, and once hearing my diagnosis, and noting the diffence in run time, simply swapped mechs to an R-84 machine where it never would run that far in one go and would likely not give any indication of trouble very soon..
They were then sold for home use, and I heard no more about it.

The R-88's sold by the Australian distributor had a board that looked identical to the R-89 and up, but was slightly different electrically. There was no pricing board.

What you are saying is true, but note that R-88s have been known to have 2 very different types of CCC board fitted in them. Your post applies if it has the CCC like in the R84 - R87 fitted, but many R88's have a version of the R89-94 CCC installed.

Note that this CCC while it looks the same as the R-89 type, it is electrically different, but all the IC's are readily available standard types, and the chip you link to is not used in these ones.

What is the CCC number on your R-88?
Is it 6-08870-04? or 4-07773-05? It should be the 608870-04 this board
uses one of two custom chips -03 or -04 the alternative chip can be
purchased from the USA from CD Adaptor or I still have some of the
original chips in stock.
