I have to questions I hope some could clear up

Background:
I have a jamma cabinet with a 20" monitor (samsung not sure model) .
I have ordered a j-pac so the questions is....
pc will be 800 athlon 320mb TnT2 32mb
1. Will the new act-labs one work with the above and what input will it be ?
2. Also that mad dog mcree brings back memories of spending a fortune would it work on an arcade monitor ?
