Looking to repair a Gottlieb System 1 display and it needs this chip. Tried Great Plains but they don't have the 6116.
Any other sources out there?
Thanks,

You can use a 6118 in this application I believe....

There is a seller on ebay that offers them at a low price. Shipped from China, so it takes a little bit of time to get here.
Lot of 10 chips (slight discount): ebay.com link: 10PCS DISPLAY DRIVER IC ALLEGRO DIP 18 UDN6118A
Single chip: ebay.com link: 1PCS DISPLAY DRIVER IC ALLEGRO DIP 18 UDN6118A
I think I've used about 30 chips from this seller by this point, and all of them worked and were not counterfeits as far as I could tell.
I'd prefer to buy in the US, but these chips are so ridiculously expensive here right now, especially if you have a whole set of displays with bad chips to replace.
Check out the links ForceFlow provided. I fixed a whole set of displays for my solar ride machine with the same seller.
The 6118 POLIDA has from the eBay link above are indeed good. I have used them myself. I don't even think those are remarked. They are really nice used pulls or NOS. At a dollar each... wow stock up. They go for 10 each on pinball retailers.
Waiting for someone to link the video of Chinese people harvesting ICs out of boards to Sarah Mclaughlin.
FYI -- photo of real UDN6118A with laser etched part marking. Parts were bought at about same time as LTB from Allegro.
Polida sells tons of counterfeits, as long as you know this upfront. The ones they sell may have started life as some form or date of UDN6118A but still stating the fact that they do sell remarked parts ... and lots of them.

If all Allegro devices from similar date codes should look like that imprint, pinball component resellers may have been duped by remarkers. Makes you wonder if some of them do not have a picture of the exact chip because of that.
But the big thing for 99% of the people is.... does it work?

Nah, I think the reason most people don't have photo's is:
A -- it takes a lot of time to do that AND keep them current.
B -- some of us have sucky photo skills and/or cameras.
I've bought good number of fakes of obsolete parts on eBay, but I've still come out on top $ wise. As long as you go in under the assumption they are most likely fake, then all is well.
The worst was a few years back when I replaced a few OTA CA3080 ICs in an analog synth (OBXa) from a lot of 10 I bought from eBay and spent like 50 hrs debugging before I realized they were junk because you never suspect "new" parts. Now I test all ICs before they go in anything.
