The Internet Pinball Serial Number Database or IPSND collects serial numbers of pinball machines and publishes a database of these on the Internet. Our goal is to make available a registration of all pinball machines in existence and allow tools for slicing, dicing and visualization of the data.

Did you know??? Williams Electronics ran two production lines and assigned blocks of serial numbers to each line ahead of time which adds to the complexity of their numbering sequence.

Site Updates
As I mentioned a few weeks ago, the site needed some work regarding it's hosting configuration. I was able to move the site off the more expensive VM and onto a generic app service host. While I figure out pricing vs resources (CPU and Memory) the site may run a bit slow over the next couple weeks as I tweak things. I will see if I can get it as performant as possible and report back here!

Website Needs Update Badly!
Hi All.... Just fixed the map on the game serial listings. Looks like Google needed a Credit Card attached, not that our traffic is that high that I get charged, they just want a Credit Card in case I believe.

On another note, the website is in need of modernization pretty badly. It is running on an Azure VM right now which is considerably more expensive than publishing it up to Azure as a generic web app. I need to look into that soon. Additionally, overall, we are really running 2010 technology here. I trying to think of options on a rewrite (Im a .NET kinda guy), but if anyone out there is willing to help, email me please. Also looking into other options. The codebase is quite large as you can imagine. Thoughts are welcome! jess@askey.org
