Reaching out in hope that someone on Pinside has experience with one of these, as I may have questions to ask as I go along.

I have been looking for one, in order to round out my collection of WMS testers, and recently tracked one down. This is usually a case of having to take what you can find - not a situation where you see a lot of them and can be choosy.

I picked this fixture up from Lloyd @ Coin Op Warehouse. Price was $465 + $45 shipping.
Lloyd also sold me the 7 digit display (late Sys 6, all of Sys 7) add-on for another $100, but with no displays.

I also bought a nice original manual on eBay for $28 shipped, and a nice set of used displays out of a Sorcerer (compatible) for $157 shipped.

So, I'm in at about $800 at this point.

I already have a few Sys 3-7 boards in my stash, will have a complete working set for the fixture, not really sure what I have in them, because I've been hoarding boards for 10 years now

Things I lack at this point:
Sys 3-6 displays. I have a 'borrowed' set from a friend to get me going, although I don't know that they work 100% yet.

Some pics of what I have to work with in this thread:

Now, to the questions part

Where should the speaker be in this unit? I don't see one anywhere.

Somebody added what appears to be a set of RCA jacks to the front panel. I traced the wires, but haven't figured out where they end. I'd like to add a speaker, which should be no big deal.

It appears someone added their own switch matrix tester. Turn one dial to the row #, turn the other to the col #, and press the button! BAM!

I have one of these, and will just install it on the control panel, over the holes that were cut in it:

This momentary switch appears to be connected to the header that the coin door buttons connect to. Where should it be mounted?

How was the additional display board mounted to the fixture? I've seen some hung off the sides before, but that makes little sense, considering the displays would be mounted the wrong way if I attached it to the side?

Thanks Mario.

What's the story with the P2 display? I see a number of these with a different P2 display and a note on it about some power supply.

Mine has a different transformer setup it appears, too, where there's no cage over the xformer, and there's no indication that there was ever one.

Well, it's a good sign....

Removed the extraneous switch matrix testing stuff, and cleaned the stainless front panel a bit

Replaced the cut off power cord end (I'll order a new, longer power cord - but I was impatient)

Unhooked all the outputs from the PS, fired it up and checked voltages. All voltages good.

I installed a master display and P1 display, plugged in a CPU and driver off the shelf I had set up for Flash, and fired it up...

And everything works!

The test fixture ROM itself is pretty disappointing, it looks like all it does is scroll some digits on the display. Had hoped for a bit more, but I guess you can't have everything.

I do need to order a bunch of connector housings and pins to repin everything, find a sound board, install it with a speaker, etc. Probably will tear it apart and clean everything, and try to straighten a minor bend in the tray the CPU board goes in - it's tweaked just far enough that the pins in all 4 corners of the CPU board tray don't line up with the CPU board. The CPU that was in it actually looked like someone had stepped on it at one point.

Probably will get a cap kit for the PS, too, as the ones on there look a little tired.

So I could switch it to a regular P2 display by simply rewiring P2? I'm not sure whether I'd rather have a shuffle display, which I'd likely have to track down, or just rewire it for a regular display. Doubt I'll be testing any shuffle displays!

I actually have a manual, but it doesn't talk much about operation of the unit!

Are you talking about the board with the interconnect on one end that has a clamp that fits over the 6800?

If so, no, one wasn't included. I'd like one, based on what the manual has to say about it

The manual for this tester is honestly pretty darn good, and I'm almost certain the schematic for that board is in it!

Found the speaker wires! Tied into another harness and just wound up. I will find a speaker and hook it up. Still need to install a sound board.

What's the big hole in the left side of the cabinet for? It's almost directly opposite of the cooling fan on the transformer. Doesn't look like it's ever had anything in it.

I read about the ROM board, but wasn't worried about that because I had the test ROMs and didn't figure I'd need it.

This is smaller than my WPC test rig, and my Sys11 test rig. I added a back board to my 9/11 rig, which I put a set of sys9 displays on, and a dual 16 digit a/n board so I can test pretty much every era of sys11 game. I know Jerry Clause has a DE PS and DMD on his rig, for testing DE CPUs. Good idea, if I ever get into any of those, perhaps I'll do that.

With all 4 of the WMS test fixtures, I'm beyond out of space. But I'm using them all enough that I can justify building an additional workbench. I've got a few issues with the bench I have now that I'd like to rectify on the 'next' workbench. My work space is relatively small, so I'm trying to optimize it as much as I can.

I'm not sure my rotary selector works. I think the circuit breaker in my fixture may also be bad. That's definitely something I'm going to dig into.

The cpu carrier was mangled, I fixed it last night. The Sys3 CPU that came with the fixture is heavily warped towards the center. The pins the board fit over also were bent inward in such a way that a regular CPU wouldn't fit over the posts. I carefully straightened the 4 corner tabs/posts so now a CPU loads and unloads effortlessly.

My connectors are all pretty needy in being rebuilt. I checked, don't have enough parts on hand to do them all, so I'm going to place an order. I've had to rebuild pretty much every connector on all my fixtures, save for the WPC-95 one which still has all the originals intact. Guess it hasn't been used as much!

Also need to fuse the bridge next to the transformer.
