Hi,

This is Brian, (Kipper2k). I am wanting to create a SMD version A500+ type board and would like to add new features. TBH, i don't have the time to start from scratch and want to start off with a .sch and ,brd file so i can update and then produce gerbers with the intent of creating a partial assembly of all those little components that eat up time soldering etc. I will release files so people can do this themselves. The cost of SMD will be much cheaper than using through hole components.

So my questions is, Has this board been proven working, Are there any Eagle files available and lastly are you willing to share the info so i can get started.

Thanks

Brian

I built this SMD A500+ and it works (with 8375 Agnus and DIP RAM) https://github.com/gazzmaniac/Amiga-SMD-500
There are issues with the port placements and holes also and I believe maybe still with the soldermask around U33/U32?

The files available here have been tested and proved working very well, with only a few annoyances which have been fixed already. Some improvements have also been thrown into the mix and a V2 was born. This has been tested and proved working just as well. It will be released soon but the license will be changed to non-commercial. I have the intention of releasing it under the old CERN OSHW license to any individual who does any "significant contribution", but that means they will have to share their modified sources in the same way. And "sources" means "full project files" as you can see here, not just Gerbers.

The project is done in Kicad, so no Eagle files, sorry.

Anyway you can follow the development of the new version on my hackaday blog: https://hackaday.io/project/180442-rmixx500-amiga-500-mainboard.

Hi, Thanks for the info. I will post all my files, gerbers and eagle, and if i get ambitious i will learn kicad. It will be an a500+ board but the layout may be slightly different to allow for all the mods flying around. (I did add the ad724 composite/svideo design to the board design, taken from the "Narmi project"

Can you take some HiRes pictures of top and bottom of the board so i can see closeups of components and jumpers please.

Thanks.

You can just load the files into kicad. The BOM is also there.

The gerbers posted at his site are reported as being bad by jlc. i posted closeups of the errors in his gerbers on his github (that i found). I do not know kicad well enough to start tweaking his files to make gerbers as i use Eagle cad and i dont want to risk introducing more errors and submitting them to JLC.

No worries, i will use my eagle files and cross reference his. I intend on doing the partial assembly too so whoever wants to get most of it soldered should be able to at JLC
