Hi,
can you tell me what's the Code is?
BP8890 with MC68HC11A8.
Code must start with 1 or nothing.
Thanks.

Try 1594........

nope.

**ikaruga** · 17th November, 2019, 08:09 AM

Any other suggestions?

Try this dump, code is 1234

Ok, it would be great if someone could do it with my dump, because I already soldered it in again... 🙄

Thanks! But don't work either... 🤔

The code is in cells 18A, 18B and repeated in cells 1C5, 1C6.
Your dump SQR88 looks bad.

**ikaruga** · 17th November, 2019, 08:17 PM

Thanks! That's not so good. Ok, i'll solder it out again.

Some lateral thinking,
find another dump that has requested a decode and clone?

When you desolder it, can you read the ROM?

A dump with known Code like 1234 is perfect too.

I have a XProg-M 5.5.5 here. But it makes some "device is silent" errors with the HC11A8...?!
So I sended it to a friend who was able to read the EEPROM (obviously it was damaged)
Now I will write your dump.

Just another question. Is it possible to read the EEPROM without desolder the MCU? (I don't have much experience)

Yes.It is possible, but all connections to pins should be cut: 20,21,17,2 on both sides of the circuit board.
And use the simple interface on MAX232 and the program for example Motorola Cracker.
