Hello,
I and a group of hobbyists have managed to acquire a used Shimadzu GC-17A and QP5000A GCMS unit from the mid-90s. Unfortunately, it didn't come with the PC software, so I'm wondering, does anyone have access to a copy of the PC software for it that we could examine and decompile?
We're currently trying to pull firmware off the device so that we can reverse engineer the protocol it uses, and write a driver for it able to run on a modern operating system, but having desktop-side software available would definitely make the process easier. If we do successfully reverse engineer it, we'll post what we've managed to get on GitHub.
