I have two Apple 1 Replica’s, the Vince Briel Replica 1 SE and the Achatz A-ONE.
Both have a 6502 and a 6821 and the original software. Video generation sid one in a affordable modern way, so not real clones.

Fun computers to work with, the first ‘personal computer’ in a very primitive format!

Pages with information on teh Apple 1 and these Replica’s
