beomaster 3500 software

13 replies
Hi,
Would like some info on the upgrade chip for the beomaster 3500, which gives it 2way control.
I've seen the topic in the archive,2bur/richard mentioned he has done several upgrades, but his last post was somewhere in the early days of 2012, therefore this post.
I've come across some chips,
  • 8341094 vervangt 51 IC 3
  • 8341095 vervangt IC
  • Software 2.2, 8341178

I guess the last one is for the bm, correct?
Is it an easy job, like just carefully flipping the chips?
Thanks in advance,
Dougie


Hello, 

Should I wish to upgrade the sw of a BM3500 to the sw of the BM4500, how could I get the relevant eprom?

Will it give me access to the timer function?

Alain

Hi Alain

You can buy a cheap broken BM4500 or order the eprom from B&O (don't know whether this particular chip is still available). Memory chips for Beomasters are rare on ebay.

Yes, it will give you all the functionality of the BM4500 including timer function (BM3500+eprom BM4500+Housing BM4500 = BM4500 as you can see in the repair manual of the BM4500).

Good luck and best regards

David

Maybe a Eeprom copy would help. Have about 15 BM4500's. Made a copy once for a BC9300 which was totally dead and volia, back to life!

Hello Leslie, 

I asked B&O but no answer so far, if you can provide me with such copy I would of course be delighted.

Is it an idea to make the software downloadable on this site? Maybe for silver/gold users only

Need to find time to do that. Friend of mine can make a copy of this BM4500 Eprom. Any specific S/W version?

Not sure if that's allowed?

probably not if the equipment is still under copyrights protection. 

I am not sure about the 25 years delay for this

any version will do
