Bifrost owners who would like to swap out the analog board themselves (aka "Uber"), here is a pictorial guide to get you going:
I'd like to add a little something for folks that don't often take equipment apart and don't like screwdrivers. Many probably know this but it might help someone that's never done this. It's a couple tips for removing and replacing fasteners.
1) When removing a philips head fastener, it is very important to have the correct size screwdriver. The worst case is too small a bit that will strip the cross slots.
Use the largest bit that will fit in the slot.
2) Push straight down on the fastener and "crack" it loose. "Lefty - Loosen" "Righty - Tightly" I like screwdrivers like the one pictured, because the red-head of the handle turns while pushing down from the palm. The Bifrost screws seem to have a bit of lock-tite type of compound so they will stick a bit when removing them. Apply downward pressure most of the time you are backing out the fastener.
3) When reinserting the fasteners don't completely tighten one fastener and move to the next. Instead just "start" all the fasteners on the side you are working on. Once they are all started half way, move around and snug each one up. You are not building a race car, snug is just fine. This procedure helps to ensure that all the holes line up. Pay special attention to the fastener when starting it in the hole. It should go in smoothly. If not, Stop, remove the fastener and start again. You don't want to cross thread the holes. This is a "feel" thing. If it feels wrong, it's wrong.
