Impressive, and thanks for sharing.
A couple of questions: 1) What thickness is the board/PCB? 2) How did you figure out how to draw the inner layers (assuming it's a four layer board)? |

BTW: I spread your blog post link on a few places. |

Has the FPU been fixed on this so if you install a FPU it doesn't disable the accelerator?

Nice work Chucky. This level of reverse engineering is spectacular to watch.
Thanks for keeping your work open. I can't wait to see what people do with the source. |

IMPORTANT UPDATE!
I just found 2 issues. one "more big" and one less big. first the BIG one! as I added a possability of having 2 +5V lines via the DIN connector.. I have noticved that when putting in an A500 PSU you will have a short to ground.. as my lab-PSU does not (apparently) have the sheild connection connected.. I never notived this. but with a proper built adapter or a real psu.. it is connecte. and. yes I am stupid. connected that pin to the din connector.. so using a square connector. cut on the top side of the board as pictured. 2nd thing. I moved C409 after doiung my R1200 prototype sown so you could use the TH 4.3MHz oscillator.. this made that the videopart will not have +5V, so you need a jumperwire from PLUS from that cap to the plus of C54 and that will work. |

My goodness, this is exceptional work!!
How does one go about ordering one of these? Would love to get a Rev 1.1 when they are eventually available. EDIT: OK I just found out that they are being sold on Amibay. Cool! Quite happy to wait for a Rev 1.1. Last edited by sean_sk; 28 August 2018 at 08:51. |
