Mainframe IBM Large systems programmer here 30 + yrs.,
Not a local so do not know about schools here but I see the grouwth in the IT market on the networking side. Every piece of hardware on every platform has to talk to each other now. Getting CICSCO certified is a big plus and there are self taught courses and classes for that. Trick is getting your foot in the door and then you have options for a career path. Oh yea lets not forget about the mainframe, believe it or not COBOL programmers are still in high demand simply because of the trillions of lines of legacy code still in use. As far as the systems side that I am on lots of classes from big blue to get started but you will need employer sponsership as there are $$$$$, and years of experience. Don't forget a lot of us M/Fraimers will all be retireing in the next few years so any experience could help you there.
I would try a community college to take some classes first, get your feet wet. Anyway good luck.
