Congratulations Chucky. Amazing work again.

Wow! Impressive! Would be like a dream come thrue to have a new a1200 mb.

modrobert · 19 August 2018, 10:50

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)?

Chucky · 19 August 2018, 11:45

1. 1.6mm
2. it is mostly ground.. and. schematics. AND some cheat. amigapcb.com

modrobert · 19 August 2018, 12:02

OK, thanks. Found amigapcb.org, assuming that's the one you meant.

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

Chucky · 19 August 2018, 12:23

org..

yeah

jediknight · 19 August 2018, 20:40

awesome now you need to make some apollo 060,s to go with that sweet.

redblade · 20 August 2018, 00:39

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

ExtremeWays · 20 August 2018, 01:24

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.

Looks amazing!!

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.

wiz12 · 27 August 2018, 18:06

Will you be releasing a Revision 2 board with these issues fixed?

Chucky · 27 August 2018, 18:30

Rev 1.1

Will do it tonight.

Chucky · 27 August 2018, 22:28

haven't done the update today. I want to test some more stuff first..
and tomorrow loooong day at work. so update in 2 days..

sean_sk · 28 August 2018, 08:45

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.
