1999 Rock Shox SID XC compatibility with modern disc brakes?

[豐JEDIMINDTRICKS]

Noob here and thinking of buying some 1999 Rock Shox SID XC forks to go on the Rock Lobster Team Tig SL frame I've just bought. Just wanting to know if the disc mounts are compatible with more modern disc brakes or would I need to be looking at older disc brakes? Any advice would be much appreciated

So, I'm reading that modern disc brakes aren't compatible with these older forks without adapters as these forks will have an old international standard mount. So now my question is what is the newest series of Shimano LX/XT or XTR disc brakes that will support these forks without serious hassle?

Those are "IS" mounts, no?
I believe you just get an adapter, based on the rotor size you're using............ I think.
