Excellent! With these available it should be easy to make a 486 version. Slap in a VGA card and a SoundBlaster and the ultimate retro PC might just be an Amiga

If anyone thinks they can use these Gerber's to create a 386 Bridgeboard with no additional work - well that is wishful thinking indeed! |

The Cyrix SLC chips only have 1k cache. You can replace them with the TI SXLC chip which has 8k cache, and that makes a decent difference towards offsetting the slow 16bit memory bus

I had no idea what has been going on with the Amiga PCB scene. I removed my comments and apologize to everyone involved. I appreciate all of the hard work from everyone.

People in the Commodore Amiga group on Feacesbook (pun intended) wrote that my Gerber conversions of the board layouts at amigapcb.og were unethical, because I didn't ask the owner of the site for permission:

![]() I think there was a developer working on a Pentium bridgeboard in the late 1990s... the "The Pentitrator" I think it was called in the advertisements. Shame that never got finished. |

![]() Both my A2386SX Bridgeboards were damaged by battery leakage years ago. I cleaned them up, but I think the damage penetrated into the inner layers (it's a multi-layer board). Without a schematic available I'd almost given up. Since these boards don't rely on any rare Amiga custom chips, I think I might check the data and consider re-making the PCB.. |

It would be nice if any of these re-made boards incorporated some simple upgrades, such as using a SIMM instead of ZIP RAM, and increasing the memory to 16MB as outlined here: aminet.net/docs/hard/A2386_16MB.lha

Scrat promised the 'owner' of the original Commodore Gerber files not to release them to the public. In my view, this secret deal suggests those files were illegally obtained from Commodore from the beginning. Scrat converted them to SVG data and build a brilliant site around it to view them. However, what I don't understand is, Scrat himself converted the original Commodore Gerber files to the SVG format and I converted this publicly accessible SVG data back to Gerber files. I didn't release the code of his entire site or even the SVG data. So who should have asked whom for permission?

For what it's worth a fair few people (including myself) tried to explain this very thing! But some people just don't want to hear this. In my opinion you did nothing really wrong. You never "ripped off" the work of AmigaPCB. I think that the original Gerber files (like a some other design artifacts that one can find in the German Amiga forums) were definitely obtained from Commodore Germany through "unofficial" channels. For some reason there is a bit of "protectionism" surrounding this data, perhaps they are all very concerned about potential repercussions, but I don't think it would matter anymore.. |

Did anyone ever tried these or ever had the Gerbers to build boards from these ?
That would be a project worth to complete as we really can't buy these boards anymore... |

I absolutely do not understand the protectionist attitude of so many in the Amiga community. Who are they protecting? A derelict company that went bankrupt 30 years ago? A company whos IP has zero commercial value in 2021? It only hurts the community and advantages no one. |
