PCB 326298 "replica"

@snickers

if you have not had time to look at it dont feel bad about it

I have just added the final version to github

that is if no improveme can be made

-----------

"Endgültige" Version hinzugefügt

Das ist, wenn keine Verbesserungen vorgenommen werden können

and this is a 326298 Rev A ?

I hope we can do with english for this one

I have spend the last few days looking very carefull that i did the tracks as close to the org. board as i could, but again the more eyes that looks at this the better

I have also spend 3 days with all the components that i removed and sorted them. i now have 10 cupcake molds each filled with the components from each of the 10 zones on layer I2

I have then looked at the text on each component to verify they are right. Strange enough commodore did not stick 100% to their own BOM, but about 80% of the BOM is a match

I then made sure that all the component in sprint layout has the right value.

NOW what?

Those that has the skills and time can help me in this way:

1. Zoom very close and check that i placed everything as good as it can be done ----- i think this is best done in sprint layout as you can have the org board as background
2. If you have a rev A board you can help by checking that i got the values right ---- but remember that commodore did not take documentation and quality control that serious (whatever worked is the rule i think)

if you dont have a board i have included a ton of photos on github: https://goo.gl/6oaPiK

The thing next to R5 looks strange, you are sure this is not just accident damage?

I got a picture from one that had a working RevA and on that one there is nothing next to R5... the picture is also on github

and at CR1 there are also 2 components in parallel that i have not seen before

again i think they just did what worked and made adjustments as they figured things out, some stuff might be found in the next revision and i think some stuff was never documented

a few burnt traces should not be a problem as long we can see where the traces stop and where they should go without doubt then we can use it

my board was without chips but with most of the other components on, what state will this board be in in regards to components?

how it looks sorted: http://imgur. com/a/YEsin

pic 2 are the leftovers

one of the 2 components i know where should go... under the crystal.... i made the mistake of not strighten the crystal when i took pictures

the other one i dont know.... but i will figure it once i get a board made and start to put new components on. I have updated the BOM: https://docs.google. com/spreadsheets/d/1Gl0Q71u6fKLPRA9HQiSG8-xY8tPweMwXuy_UGQ1Iayo/edit?usp=sharing

there are 10 zones on it, but everything is linked to the first page. ie the 4164 chips are in 2 zones but on the first page it says i need 8 of them and a link to where i found them

this makes it very easy to make sure i have everything and in the right amount. what i have not had time to check are if all links are still valid and not sold out etc

i had to put a "space" after the dot in dot com

or else i was not allowed to post

so you have to be a bit creative to get the link to work

docs.google. com/spreadsheets/d/1Gl0Q71u6fKLPRA9HQiSG8-xY8tPweMwXuy_UGQ1Iayo/edit?usp=sharing

if you look carefull there is a space before com

also remove the box with arrow symbol

eurocircuits has some reasonble prices for a raw board... ie no silk screen and no solder mask etc... just raw copper with holes

now i have a hard time figuring how to setup DRC in sprint layout so that i use their rules to check the board

they have a guide for kicad, but how do i translate that in to the drc box in sprint layout? http://www.eurocircuits.com/blog/kicad-design-rules/
