Bridgeport BTC-1 Milling Machine

I'm the proud new owner of a BTC-1 milling machine. This isn't really my work, someone else converted it to LinuxCNC and I just bought it from them. There is 0 documentation of any kind available for this machine, so it is impressive how they reverse engineered it. My job is just to figure out how to use it and LinuxCNC.

Here are a few photos of it

Thanks! That info looks very helpful.

This machine has a tool changer, that is probably not worth the hassle of getting working. But it is really cool nonetheless. Here is a video of two of these machines with working tool changers:

Any recommendations on how to get started implementing a complex tool changer in LinuxCNC?

Personally I'd do it with ladder logic, but that is what I'm familiar with. There are a number of possible ways to do it, but it comes down to what you feel comfortable doing.

Ok, just started learning ladder logic.

Here is a video I just took of the cool mechanism that moves the toolchanger to a different tool:
