Hi,

I found this slightly beaten up board littered on the side of a busy street:

(I removed all ID labels from this photo)

I stumbled upon this repo when looking up the chip numbers and think it would be fun to revive this literal piece of trash and build a small clock from it.

I have limited experience with electronics and wanted to ask if you could give a few pointers on which pins to solder exactly for programming it (can I use just the debug interface?). I noticed that the PCB layout is slightly different to the one in the readme. The readme also does seem to display multiple different boards.

Thank you very much!
