I want to connect an mp3 player or even a tape cassette player to my BBC-B computer but its only got a 7 pin DIN port, A 5 pin DIN plug can be used as the other 2 pins are for motor control and not needed.

How can I connect such a thing to an RCA/Phono or 3.5mm jack?

A quick look at this article tells me that's some proprietary kind of serial port.

I doubt there's any way to adapt a sound signal to a serial connection in any way.

What are you trying to do exactly? Record sound or music from the BBC-B?

BTW, that's probably the oldest computer mentioned in a tech question here. :lol:

EDIT: Looking at it again you might be able to do something with the UHF and video ports if you have access to a VCR or a TV Tuner card.

Also, I'd recommend finding a site in the UK that sells adapters. Just scour the site a bit and see if you can find anything that might be of use.

No ,Its the Tape in/out port The BBC-B uses DIN's for nearly everything.

I could BUY a tape lead but dont want to spend the $20 on a system that cost me $10 with a shedload of ancient software.

The lead is so I can play the games that are on tapes

The other option is to locate an old tape cassette recorder with a DIN socket, It used to be standard I think in the 70's???

I can also convert them to mp3 for archival purposes.

I just meant the interface for sending the data, not the connector itself.

It doesn't seem like the interface that connects a drive to the computer could be adapted to an audio interface like an RCA or mini jack.

I could be wrong though.

There probably isn't any cheap way to do it. You're going to have to buy a few adapters at least. Maybe something like these 7pin to 5pin and 5pin to RCA adapters:

But again, the interface on the computer seems like it'd be for transferring digital data, not analog sound.

The econet port is for data ,The cassette port is for analogue sound.

I was thinking more of wiring it myself.

Ive joined "The Vintage Computer Forums" but still waiting for activation.

The BBC-B came with loads of tape games, Like this...

So I wanna test em.

This is a BBC-B cassette lead

I think the extra jack must be motor control (you can stop/start the tape recorder with the computer)
Not as expensive from that site but still a lot compared to what I payed for the BBC stuff in the first place.

I remember those things. I always thought that'd be a pretty hilarious addition to a high end gaming system.
