The 78x series does.

Dave are you allowed to say whether that programmer can/cannot read from the chip?

IIRC I tried that when I played with it and got nothing. So I presume it's protected.

I can't say I am surprised. With the lengths they went to obscure which chips are used I would be a bit perturbed if there wasn't some type of read protection. It's a bit of a bummer that you can't at least read out the EEPROM values within the CPU to enable repairability. Of course there are safety issues with doing modifications/repairs on a DMM, so probably for the best in this case.

OK, I have a BM789 that has old firmware, how can I get it updated?
