Took me right back to my education and I never really thought about impedance values and why they were chosen.
We used to build 10base2 BNC terminators ourselves with empty connectors, a soldering iron, crimp tool and some hot glue using 47ohm resistors albeit with low tolerance values.
According to my boss they outperformed the industrially produced ones.
Back then, the network problems I was facing was either on the software/configuration side (wrong IPX/SPX network id) or simply faulty pc power supplies (I.e. getting shocked by mains voltage when touching ground, frequently happening after thunderstorms; also the terminators would be hot to the touch in such cases).
