If it still has the steppers (and they are still functional) and

> I found a bridgeport machine that is also without half it's cards, however the motors look like they could be 6 wire steppers and have the part number O25805 alternative to O26794 they look like they should connect to a Geko drive and a power supply (such as the mighty cnckits.com). Can anyone tell me if it is worth buying this machine for a possible upgrade to CNC as the whole thing is old but well made (except cnc controls that is).You will get many positive answers on these questions.
