I'm thinking one serial and one cassette. The 8251 for the cassette. I can't make out all the chips at the pins? The board was hand laid out. Is there nothing on the bottom but traces?

Trying to identify the S100 serial board in my Imsai 8080. https://imgur.com/eZyOVT5 I assume it was a kit. There are wires from behind one of the ICs that go to DB25 on the rear, along with other DB25s with a few pins (maybe cassette input.) Any help appreciated. -- : Ethan O'Toole
