These were on atari system 2 boards and other older atari boards. would anyone happen to have one of these oscillators? or know what are the compatable replacements?
this brings up one problem. there seems to be two types of these. one with Load Capacitance: 20 pF similar to the one you listed. the other is series. Is there issues with selecting the wrong crystal/oscillator?

problem solved the part is a series crystal/oscillator. the easy part # for mouser is MP143 it is the exact spec as to the original NMP143. if anyone ever needs one for any atari system 2 games i hope this helps.
