Amiga 4000 Replica with Schematics

$5,145 of $5,000 goal

Raised by 116 people in 2 months
As many owners of the Amiga 4000 boards know they contain a battery and several electrolytic capacitors which when age and leak cause severe damage to the motherboard. The goal of this fundraiser is to have the original board converted to schematics and Gerber files. This will allow new boards to be manufactured. The schematics will allow future updates and changes to the design of the board for future enhancements or improvements. 

This work will be accomplished by Integrated Sensor Technologies, located in Goleta California ( www.isensortech.com) and will take 4 - 6 weeks for completion. Once complete the files will be released publicly and hosted on a site such as github. The project does not include any boards and is only for the funding of the engineer and the work required to complete the file conversion project. Any boards will have to be purchased by those requiring them from a PCB manufacturer on their own.

The first release candidate for the final schematic has just been posted to the Github schematics folder!!!! Please review and let me know if anything seems out of place. I will be getting back to them for the approval to move forward in no more than two weeks!! This is the final push guys!! The github page for schematics is located here: https://github.com/Acill/A4000RevB/tree/master/Schematics

This just in from the company doing the work!!!!!! "I will be finishing up the schematic in the next couple of hours. I will provide a PDF in addition to the Mentor PADS database.
The schematic/netlist is critical so have the backers review it carefully. There are some of my notes added.

I'll check what you noted and finalize the layout after the schematic review.
It should take a few days or less to complete once the review is complete."

Hello everyone and thanks for being understanding as this project moves on closer to completion. earlier in the week I contacted the company hired to do the work on converting the board into data files to get a status update from them on the progress. The delay in completion is mostly due to changing the project goals due to feedback from a large amount of you that donated into the project. The original intent was to get the board done in a way we would have gerber files to produce a new board for replacing old boards. A lot wanted all the data to be able to redesign and modernize the 4000 as well. What I did was gather all the information i could find and provide them with original schematics, parts lists, tech documentation and feedback to the level they felt would work for producing schematics, netlists, BOM and board layout all connected. This will allow anyone to take that data and change it as they see fit. It was much more work than the person assigned the project realized and is now just finishing up the schematics and netlists.

What does this mean? Well it means its just about time to post the final schematic in Mentor Graphics PADS format. I am asking them to hold off on doing the final board layout once the schematic is released to give those involved a chance to review it and see if they missed something obvious or didnt add something. Yes this is somethig they will be doing anyway and are cabable of, but they are not Amiga people like we all are. I want to make sure some of the amazing users and builders in this communiety take a look and give real feedback. I will post again after its posted and ask for two weeks to review. If nothing comes back I will then have them do the final layout and conversions to Altium and Eagle compatible files as well, then post them. We are very close! Lets pull together and do this!

The files will be placed in this GitHub location. Remember that the stuff there now is still not final, but if you get the PADS free viewer you can open the files as they are uploaded now. All I ask id you keep them here and wait for the announcement its final before you start to do anything with them more than looking.

Lots of progress this week on the 4000 project! I am pleased to present this little "sneak peek" of the schematics done in Mentor Graphics PADS! They should be finalized and publicly released on the GitHub next week once they are reviewed and double checked for any errors. The netlists are also expected to be completed by the end of next week if this progress keeps up.
