Hi-Res JPGs of Re-Designed Apple-1 Schematics

Hello,

 

After having thought about it for a few weeks, I have decided that I will share a set of high-resolution JPGs of the re-created Apple-1 schematics with the community, so people interested can make quality prints for themselves. I will probably also make a set of them available printed on the same paper I printed the complete manuals on (Munken Pure, 150 gsm).

I hope you enjoy them as much as I have enjoyed creating them.

 

Best

PS: If you want to get a printed copy of the re-designed manuals of the Apple-1, you can find them here.

This schematics are historic

This schematics are historic errorneous like the original ones.

If you are looking for a corrected version this one is better: http://retro.hansotten.nl/uploads/apple1/a1%20circuit.pdf

This is not a discreditiation of the great work of retroplace_1 it is just an inportant information.

Details about the error you find here: http://www.willegal.net/appleii/apple1-hardware.htm

I was going to suggest that you make two versions - one that replicates the errors of the original schematics and a corrected version.

I plan to issue a second version, indeed. It's just that I am not really good at electronics and probably would need help to find out which sections to change/relabel.

Hi guys!

It turns out that the corrected version is not quite right either, a good man told me. Here's what he writes:

 
"Not to mention that the "R" and "T" signals are swapped in the drawing of the expansion connector J3. The errors are present only in the drawing on the page with the power supply schematics, in the schematic of the Computer part they are good. ACI manual is also fine. J3 drawing seems to be wrong in the corrected version of the schematic, maybe someone should notify the author of that? The correct configuration is: pin 21 --> "R" pin 11 --> "S" (unchanged) pin L --> "T" It's an error that goes unnoticed until you try to build some peripheral using that drawing as reference..."
