Being regularly confronted with wretched special screws, there are all kinds of ways to get them out. The usual go-to tool is one designed to unscrew stripped screw heads.

Just the other day, I was confronted with a security screw that instead of having 4 flutes on it (Phillips head), it had 3. I just drilled it out.

Nothing worse than a screw you dont have a driver for. I resolved to just have drivers for everything

After going through several brands over the years, both domestic and foreign, that's the best set of driver bits that I have ever owned.

Kinda pricey, but well worth it.

No slotted Robertson :(

It very well could have just been Torx back then. I remember opening my original 128k Mac in '85 or so to do the 512K memory upgrade, and a weird specialized screwdriver (Torx) was required to open the case.

And n64 cartridges and cases. And snes too I think. Another trick is to melt a plastic pen with a lighter and stick it on the screw and wait for it to cool.

Ha ha, that's Some Anarchist's-Cookbook-level stuff.
