Hey Lindsey, your adapters look great!

Thanks :)

I finally got around to assembling and testing a bunch of them and put them up on the site. I had planned on doing it sooner but I've got so much on the go these days that I just didn't have the time. The only "advertising" I've done is in my sig here so I can take a bit of a slow start.

The next two things we'll likely see for sale are the Bally/Stern lamp driver testers and a Bally/Stern daughter board connecting to the expansion header and replacing all the ROM and RAM (with F-RAM). You'll also be able to leave the original RAM/ROM in place. The lamp driver testers will be a dedicated system with it's own power supply for testing lamp driver boards out of the game. It will also connect to a computer via USB for more detailed troubleshooting. Some interesting stuff. With any luck it will see the light of day within a couple months.

Thanks again for the plug!
 
I got my buddy just about to order 2 for his Williams system 11 :D
 
I'm very interested in making batteries go away in my gameroom. I think Lindsey (PinForge) is the only one with a turnkey solution for 6116 replacement, so I'll be placing an order soon.

However...the STK12C68 is a drop-in replacement for the 6264, and I've ordered some recently for about $6 each (from China, so they'll take a while to get here). I'm just curious, is FeRAM (F-RAM) better than the Simtek "autostore" solution?

Simtek is basically the same thing. They're getting tough to find though. I don't know if they're even in business anymore. I don't see any on ebay right now. If you're aware of a good source it might be worth posting it here. I won't be buying any but I'm sure pinheads will be snapping them up.

There is a Simtek drop-in for 6116 too if you can find them. There's no 5101 drop-in unfortunately. These are an equivalent to what I'm selling and should be cheaper so you could even call them a better solution. They're just not readily available. That's the whole reason I made mine in the first place. I ran out of Simteks ;)
 
Simtek was bought by Cypress; most of the parts are obsolete but the datasheets are available here. I worked out the mapping from SRAM to Simtek parts:

6116 (2kx8) = STK22C48 - only available in SOIC
6264 (8kx8) = STK12C68, available in 9 DIP packages
62256 (32kx8) = STK14C88, available in 15 DIP packages

So I'll stand by my statement - you have the only drop-in replacement for the 6116. :)

I bought N=10 of the STK12C68 from a distributor in China (link) for $3.37 each ($6 each with shipping). I'll probably have some spares, so I'll post when I get them and can test them.

By the way, the search feature on AliExpress is totally borked. You have to search for your ICs on Alibaba, and then click "buy on AliExpress.com" at the top right.

they don't have a STK25C48 replacement do they?
