m3lm4k,
Before diving into options, I would ask a couple of questions. First, do you really need to control the GC? That is, are you going to be switching between multiple methods of analysis where you will be changing GC parameters such as temperature programs and pressures? Second, do you want to work at vastly different concentrations for your components of interest? Third, are you figuring on running this system on an autosampler? If all three are yes, then look at all the vendors here who would be willing to sell you software. If yes to all three, then you need to also answer the question about the HP-IB/RS-232 card on the back of the GC since that can change your options.
If the answer to 1, 2, and 3 are no, then the question is one of simply collecting the data rather than controlling things. If that is the case, you have a more options. If 1 and 2 are no but you still don't have an autosampler, you still have options (meaning not just buying a 7673.) If 1 and 3 are no but 2 is a yes you have an interesting problem in that just getting the data out from a 5890 limits you to 0-1V output and ranging.
Not a simple answer, sorry, but in reality not such a simple question. Perfectly willing to expound if you want to abuse yourself some more....
Best regards,
