I just joined the club!

I have a question about the monitor. Everything I've read indicates the monitor will either be a Wells Gardner or a Ducksan. I noticed my monitor is fitted inside a bracket with a Wells Gardner sticker, but on the back of the monitor is a giant label that indicates it's a Samsung model A48KRD82X02. Can anyone explain which monitor I have and what install hassles to expect if I want to do the Ultimarc video amp mod?

With my machine almost 20 years old I knew it was time to replace the batteries inside, but I had been putting this off because I was dreading having to separate the PRISM sandwich card to replace the BR2325 button cell. I don't have a divider tool, can't find a divider tool, and have no idea how to separate the card with a toothbrush like some people suggest. (I'm going to assume it's a secret like how people in the future use three seashells in the restroom.) Even if I did have a tool, that thing is sealed tight so I know it's not going to survive my accident-prone self from mangling it somehow.

So I figured out a way to do this in minutes without ever worrying about taking apart the PRISM card and breaking it. All you need is a small flat head screwdriver, needle nose pliers, some electrical tape and a pick tool like the one below...

First, take your small flat head screwdriver, direct it into the card (in the direction indicated below towards the battery) and stick it under the battery.

Leave the screwdriver there, then take some needle nose pliers and pull the battery out a bit so it's no longer fully in its socket. Remove the pliers for a moment so you can pull out the screwdriver. Now use the needle nose pliers again and this time pull the battery completely out of the sandwich card.

Next, I recommend wrapping electrical tape around the grips of the pliers for the next step of reinserting a replacement battery. (You don’t want to scratch and scuff up your new battery and – as I quickly learned while experimenting with the old battery – you WILL scratch and scuff it up if you don’t do this.)

But first you have to figure out a way to lift up the clip in the battery holder and keep it up. Enter the sandwich board from the opposite side with your pick tool (as depicted by the arrow in the below photo)...

Slip the prong of the pick tool underneath the clip from behind and gently lift it up. Then (with the electrical tape already applied to your needle nose pliers), enter the board from the opposite side and start to place your new battery under the raised clip (entering from the same direction as the first time you inserted the pliers). Once it has started to get under the clip, remove both tools to inspect. Then reinsert the needle nose pliers and continue gently sliding it in until its completely snug inside the battery holder. Super easy.

By the way, I was actually surprised after replacing both the BR2325 and the CR2032 (on the PC motherboard) that you do not lose your game’s ROM version, any settings, or high scores. The date/time resumes from when you removed the old CR2032 battery so the only inconvenience is you will now need to update the time after you power on the machine.

(EDIT: Sorry about the links. I can't figure out how to post photos in between the text in my tutorial!)

I did not. Was surprised by how dust-free the inside looked (along with the fan) so I left everything else alone.
