Bridgeport EZ-Trak,to buy or not?

Hello,first time user here.I have a chance to replace my 1965 step pulley bridgeport with a 1991 EZ-Trak 2 axis mill. The mill has a recently replaced spindle,power drawbar,Bijur spray mist and a South western industries controller.It is in very good working condition,asking price $5,500.My question is will i be buying an obsolete cnc system that i cannot get components for? This is a one program at a time controller. The owner tried to obtain software to converse with a computer, but gave up.There is an RS232 port on the back.Can anybody help me with some information Thanks Brian.

Are you the retrofitting type? :)

If the machine is mechanically sound, it may not be such a big risk, if you are willing to retrofit it to a PC eventually. It surely would be nice to get it talking to a PC first though. Heck my old 1980 Bandit could download and upload to a PC. As a matter of fact, that's the reason I bought my first PC :D
