I hope these are on topic. They all seem to be about 20 years old. I can't find any copyright. I have the following HP manufactured boards. 93799A (HS BUF INT) (I have 5 of these) 69731B (Digital Output Board) (I have 2 of these) 13037 (INTF) 12979(I/O) buffer Anybody need and/or want any of these? Make an offer (I'm a realist, I just don't want to see these go for scrap). Shipping would be from 07848 (New Jersey USA). Kelly
