this kind of machines are good for long run parts.You have to set it up manualy for each part.
The PART doesn't care if it was made on CNC or air/hydraulic/cam operated machines.
The SET UP TIME - also scarcity of the experienced skills, present-day, to DO that - is waaay to Hell and gone longer with the older technology than with what CNC has become. That is WHY it is obsolete.
If you have to work hard to earn your crust, do NOT get sidetracked into turning back that clock. It can eat your lunch.
No need to throw anything away.
I'd convert back to manual, put the machine to useful work.
I'd also
carefully preserve all the other parts. Then - maybe, some 'wealthier' day - or wealthier next-owner - a museum-grade restoration might be in the cards.
