I’ve never owned a BM6000 and apart from the CPUs I don’t have any parts for them.

I meant if anyone who can write 3870 assembler code and wants to re-create the functionality of the original program, as you are doing with a modern processor, then the piggyback CPU would be available.

BTW someone else has already been through the process of making a plug-in replacement for the CPU, using a PIC processor. It would be good to see a pooling or resources for anyone else who might be interested in reviving a BM6000.

Anyone that would want to do that is far more hardcore than me. I did that kind of stuff back in the early eighties. I don’t think I’ve ever nostalgically reminisced about those times, thinking of them as the “good ‘ol days” ;-).

When I was writing the re-CPU software, I kept thinking to myself that it would have taken months to write the assembly code that I was able to crank out in a few days in a high-level language.

I wasn’t aware that anyone did a re-CPU of a BM6000. I read of a guy that did a re-CPU(s) of a BM8000. I think he based that on PICs. The thread was titled something like “BM8000 brain transplant”.

Do you have any links to the BM6000 PIC project?

I don’t think that I would be able to do what I planned with a PIC. Every time I revisit the “wish list” for the project, I feel the need to use a more powerful processor.

A posting on this site describes the beginnings of the BM6000 PIC project.

I’m hoping a full description will be published one day before too long.

It did take months to write the original program. See:

Beomaster 6000

Thank you for the links.

I did a quick search but didn’t notice any follow-ups after the initial thread (a year ago). I wonder how much interest that there is in modernizing equipment of this era.

Would be a cool project. What kind of modernization were you thinking?

Anything from duplicating the basic stock functionality (on a modern CPU) to something that would operate similar to a Sonus device.

I’ve already started on creating a two-way, RF-based remote control.

I’m curious about what what kind of functionality that others would consider important. Integration into modern B&O networks? Integration into other networks (Matter, Spotify Connect, AirPlay, etc.)? Would anyone even bother with the BeoSystem 6000 generation of equipment if it was updated?

I acquired a new CPU from Artig (thanks again!) and the machine fired right up, works perfectly. I guess that proves my old CPU was very much dead.

Congratulations! It is good to hear that another BM6000 has avoided being parted out.

I might end up parting out my dead-CPU BM6000. As of now, it needs a CPU and a volume motor. It is kind of a shame since it is fully restored otherwise (reflowed, recapped, sliders/switched cleaned/lubed, FM aligned, LEDs rebuilt, etc.). The cosmetic condition of the machine (~5/10) is such that it would be cost prohibitive to fix (i.e. the parts would cost more than the fixed receiver is worth).

That’s a shame, but it’s always handy to have a few spare parts.

Now that I think about it, it isn’t too much of a shame since I’ve already had fun working on it and learned some new things in the process. Also, I now have a solid machine on which to experiment with my crazy ideas. Hacking this into something unique may provide more entertainment than doing a restoration.
