Pinitech 6116 NVRAM Replacements - different versions
I recently added an NVRAM module to a Spy Hunter. There are threads here that talk about memory stability on MCR boards w/ NVRAMs improved with a 10k pull-up resistor. I saw one seller on eBay from the UK selling NVRAM modules with resistors on them, but nothing in the US. It turns out Pinitech has a version with the resistor.
Standard NVRAM:
www.pinitech.com
Pinitech also has a page offering a 6116 NVRAM module for MCR boards, but it wasn't clear that it was any different from their other 6116 NVRAM module. The text on the page noted no differences, and the photos of the NVRAM modules are identical. I wrote and he confirmed the MCR version has (besides an extra $5 price tag), a surface mount 10k resistor (and a surface mount cap) on the bottom side of it.

So I suggested an edit to at least the MCR page which he did:
There are still no images on the pages which show the differences, and since a photo is worth a thousand words... here is a photo below showing 'standard' vs the MCR versions:

And yes, you can always save a bit and solder a resistor on yourself. In my case, saving $5 wasn't worth the hassle. More importantly, the space in between my boards was really tight, and the NVRAM module with the pins and black plastic tops on the pins means the NVRAM module rides really high. So I didn't have a lot of space on top of the module. I might have actually had to hang the resistor off the side of the module or underneath. The surface mount answer looks cleaner.
AnyPin DMD+ 6116/6264 NVRAM Replacement
Another option for 6116 replacement is the AnyPin DMD+. Except it doesn't come with the resistor on it.
Their web page mentions you can solder-jumper it to act either as a 6116 replacement or a 6264, however, they actually show up pre-soldered for 6264 use. When I wrote to ask why, the reply I received was "all anyPin come preconfigured as 6264, since that's by far the most commonly used RAM in pinball."
Rob also wrote, "...Usually yes, I can do the modifications for the anyPin DMD+ configuration for 6116 before they ship out. The 6116 version anyPin DMD+ that Marco sells I make exclusively for them. It doesn't have all the pins like the regular anyPin DMD+, so it can only be a 6116. I make them exclusively for them on their request."
That version seems like it is simply missing the extra 2 pins per row and is 6116 pre-soldered, but otherwise the same.
So while they seem to be a great 6264 replacement option, be specific when ordering if you want a 6116 version, and if you want one with a resistor already on-board, you might want to look towards the Pinitech. Even if you don't need the resistor, the AnyPIN DMD+ option is a tad messy since you would have a few extra pins hanging out into space if used as a 6116. The point though, is you could if you want to, and there is nothing wrong with the solution.
Swemmer 6264
Swemmer also has a 6264 version, available from Marco and elsewhere. This isn't a substitute for a 6116.

ARE THESE DIFFERENT THAN OUR 6116 NVRAM?
Yes, these are different than the "6116 NVRAM Module" we sell, even though the picture looks the same. This module utilizes the same PCB but has a few additional components to work with Bally MCR games (pull-up resistor, capacitor). This is so the module can be utilized without additional board modifications beyond removal of the original chip and installation of an IC socket.
