Previously I have posted some vendors who have old hardware they are willing to sell. Earlier this week I was in San Antonio, and I stopped by an old friend to say hello. He has several 3174 controllers, and every imaginable add-on available for them. Pallets of them! Also IBM 4700 banking controllers, and 1 monitor. No keyboards. 8" floppy drives. IBM terminals, most models available, $85 tested and working with matching keyboard, no severe screen burn. Contact bfloyd at southtexasproducts dot com.
