Hi all! Me and my buddy are building an Apple I replica, for now successfully. Recently we have tested the video signal :) However, we are having big problems (as you can imagine) with finding Signetics 2519 chips. I know many ordered them in bulk, so I would be thankful for any help (we have US address) or information.
As for the other components, the 74160, 7450 and DS0025C are the blockers at this moment. These we would probably find much easier (already did actually, just looking to maybe get them from the same source). Thanks in advance, Igor
