Changing the subject slightly, is there a bill of materials/parts list/etc. available for the parts for the Apple 1? I am aware of a few sellers who sell or auction parts kits for an exorbitant amount of money. I am not concerned with period-accurate date codes, I just want the correct , functional parts. Ideas?
I would also like to get some functional parts. I'm likely to try 4116s for the RAM (which I have in abundance) and I don't mind using a newer CPU, but the shift registers are mondo expensive. I haven't come up with a functional substitute yet. I suppose I could steal the technique of Vince Briel's Replica 1 and just put a fast MPU tapped into the furthest point upstream in the video circuit and emulate that bit (he used a Propellor) I am never going to have a photo-exact period replica but I'd like to have something that works that didn't cost hundreds of dollars for 5-6 chips. -ethan
