Great to see the cabinet in use again, to bad it didnt make much money. Offtopic: I came across some super mario toys but the are expensive!! I guess 50 euro is too much for one??
Wow yes, they are cheaper on internet !

Image as requested by Ully:


I still have to make the wiring more neat and I need to clean the complete inside still.

By the way, where was this originally inside the cab ?

thx for the pic, andré. this converter really looks as if it were meant to be placed there  ;). regarding the "sticker": don't know if it helps or if its the same, but the pac-man sticker with corresponding contents is placed on the monitor board. do you need pics?
all i need is ... PONG - and a select few others: TOUCH ME, DRAGON'S LAIR, JOUST, ROBOTRON, MR DO, SAN FRANCISCO RUSH THE ROCK!!!

I got it from Robin. It's Dutch built. Erik contacted the factory about them for a groupbuy but I don't think it materialized:

That is correct, total lack of interest.  ???  But I know now where to get them, and one day I might order some for my cabs, probably around the time my gameroom is finished.

If only.....

I just tried Arcadecollection's board (which I had loaned for a while, thanks Rob !) and it works fine. So power supply etc. is fine. I still checked all the fuses, no problems.

I checked out this site:
lawnmowerman.rotheblog.com
which is a great source for Pac info. For a dead board there's only the suggestion of replacing 74LS74 at C8.
I measured and compared with Rob's working board and indeed I get some differences on the pins there.

Next I noticed that the crystals' legs were pretty much bent on my board. I also noticed that the top obviously had been soldered at one time, but was now loose. I checked on Rob's board and the case of the crystal definitly needs to be (really ?) soldered.
I find this pretty weird, I've never seen it before on other boards. So I figured to take a closer look and then, snap, one of the crystal's legs broke. The other one was on it's way down too, so I ripped it off.

Ordered a couple of new one's and some 74LS74's.....and now wait for delivery.....

Thanks ! Just noticed that the 3 chips around the crystal have already been socketed (and so probably replaced) before on Rob's board. So I'll add these chips to the order, they cost close to nothing anyway.

The waiting won't be too bad, with RSonline, stuff is usually here within a day or 2-3. I still can't understand that I can buy 2 crystals for a total sum of €0.88 INCL. tax and they can ship it to me and still make money ?!?!? I know they probably have a bulk contract with the shipper but still....

RS is also FAST. I just tried to add the LS chips to the order, but can't do it anymore, it's already ready to be shipped (I ordered a couple of minutes before !)

Anyway, another order, so another envelope, but what do I care, no shipping costs anyway !

Tried following to get it running:

Put in a new crystal
Swapped processors
re-seated all EPROMs
Exchanged one EPROM from Rob's board (the other won't fit, Rob's board has a bootleg extension board with larger EPROMs)
Measured all the power supplies, fine
Measured the reset line at pin 26 of the CPU, behaves the same on both boards.....

I'll go and install the new chips around the clock circuit, but I have a feeling the problem is not there.

Not having a test-set up sucks....

Well Andre, now for some good news.....to cheer you up.....

Darin (PhoenixArcade) just reproduced silk-screened Ms. Pac CPO's. The CPO looks good, but I need a closer picture to see how accurate to NOS they are. But they look way better than twobits. Anyway, here is the KLOV link...
