Hi everybody.

My boss bought a used machine. A Safan press brake, that was dropped during transport.

The NC unit is in a deplorable condition. The damaged penny parts were replaced. I fixed the frame. But two ICs have disappeared from their sockets.

Since I really don't want to reverse engineer the entire schematic, I'm hoping someone has a Cybelec CNC 6000 control unit (or schematic) and is willing to help.

The two missing ICs are:
PCA 704 board, IC marked 'J', and part of PIC 705 board, marked 'C'. These should have the type, for example 74ls14.

Thanks in advance if anyone answers.
