Bundled API In Tekkit?

So I've played Tekkit Classic for a long time, and grew very familiar to the computercraft version in the modpack, but when I go to play Tekkit Main (the pack with Galactcraft), I noticed that the bundled API isn't supported. You can attach bundled wire from ProjectRed to the back of a computer, and use a command along the lines of:

rs.setBundledOutput("back", colors.black)

but nothing happens when the computer runs the program (there isn't even an error message). I checked the APIs directory and didn't noticed the bundled API there, like it was in the other version of Tekkit. So am I simply missing something, or are the ProjectRed bundled cables simply not supported?

No one here chooses which versions of ComputerCraft / ProjectRed are used in your modpack, but I can tell you it isn't going to work with anything prior to CC version 1.64.

Well, it's not "my modpack", it's just the default Tekkit from the technic launcher, but yea, I checked and it uses version 1.63, which is a shame. Oh well, thanks for letting me know!

you could manually update the mod (only works on single player, you won't be able to play servers)

Not easily; CC 1.63 is the final build for MC 1.6.4. CC 1.58 is the last build with which you can use bundled cables under that version of Minecraft.
