Recognise this BBC Micro controlled CNC machine?

[Gibbo]

I've dug this old beast out of stores, along with the Beeb, monitor and drives:



It all works but the cable is missing.

This is the port on the side of the machine:



But can anyone tell me which port it plugged into on the Beeb?

I'm hoping it was the user port so I can use something like this:



Thanks!

RS232 was born in 1962!!

But can anyone tell me which port it plugged into on the Beeb?

15 pins so it probably is the user port. Is this any help?

RS-232 tended to use 9- or 25-pin DB connectors.

Yeah, that's a DA15, so not an RS232. Used for joystick connection on a PC, IIRC. Try using analogue in on the BBC Micro.

I stand corrected RS232 was a round socket connect. The cable plugs into the user port

RS232 was a round socket connect

RS-232 is just a signalling protocol. It's been used (and, believe it or not, still is) in all manor of physical packages.

And FYI that round socket is a DIN

I meant the RS232 connection was a round socket connect on the back of the beeb

Thanks Tim that was the word I was thinking off lol, it been a very very long time since I delved in the world of the good old BBC Micro
