Doing some work on a couple ATARI 1050 Floppy drives I discovered an addon board. Here are some photos. Any idea what this thing might be? It plugs into the 6507 socket and the main board does NOT have the Tandon 188063-001K (mask rom?)
Weird thing is all the identifiers on the small board have been sanded off! You can see wear marks. Only the eprom has anything readable.
I have also attached a dump of the eprom on this board.
