Aurora somewhere?

[gorlum]

I have some faulty Aurora boards, which I am in the process of repairing. I can upload a photograph if required.

Please upload a photo. I want to replicate and post on the forum. For the common good. I already laid out QL replication

It looks like a 4 layer board - so that probably won't get you very far.

I already have a good idea of the device of Aurora. To move on, minimal additional information will be enough for me.
....Soon I will post the IPC from AT89S51.
