Maybe this ad could be interesting for you?

That's the 1960's Beomaster 5000. It doesn't have the CPU module.

Still an interesting ad with a very nice price for that system.

Martin

Edit: And already gone again, I see.

I couldn't understand the price, but quite honestly this is a really must have for every collector.

Especially if it is in good condition.

It was a set of

Beomaster 5000
Beolab 5000
Beovox 3000 (on homemade stands)
Beovox 2500 cubes

at SEK 1500 (~ 120 UK pounds) and looking very nice at that.

This years bargain for someone.

Martin

This is really cheap!!!!!!!!!!!!!!!!!!!!!!!!!!! I'm really too far away and transportation cost will kill any kind of bargain 😭

Bumpity bump 🙂

(and yes, I of course mean the '80s Beomaster 5000)

Last chance before the skip is calling (or something completely different happens...).

Just for clarity, I do not want to buy a working Beomaster 5000 or anything else that it might come with - I don't like it that much - I want to fix this one I have already 😕

What's the problem with your Beomaster 5000 "brain box"?Maybe I can help.I have the training notes for this system,and have repaired several over the years.

Hi Nick, thanks for the offer. The processor itself is dead. It's a 8051, which is a mask ROM version of 8031 - so really no hope of a straight repair without an original chip from another BM5000. If the program dump was available somewhere, it might be possible to burn it on an OTP or flash version of 8751 - only that the flash chips are much newer, I haven't actually looked if they are a drop-in match electrically.

I'm not going to scrap the Beomaster in any case - if I can't find the spare, I have other plans which will eventually be published on the forum 👍
