You would think this would be somewhere in the documentation, but if it is, I sure cannot find it. Assuming that the main board on the 8890 is where it has been since the 6890, on the right-hand side when looking at the instrument, I am wondering if it still has a hole in it so that if you needed / wanted to, you could send a transfer line out the right hand side of the GC.
Also, as a note for the designers of the code that runs this forum, I find the text entry on here as laggy as @#$@. This is to the point where I won't come back here unless I absolutely need to. It is just too obnoxious to work with.
