Just a little hint what I am doing as I am on a businesstrip and are kinda boored at the hotel :)

As they say, not all heros wear capes. Unless you do wear a cape Chucky?

Now that is a great project!

I hope boredom keeps filling your schedule this way. ;)

Will you consider reworking some connections?

I mean, for example, getting S-video from the sony encoder, an ATX PSU header instead of the weird PSU connector the Amiga has, a proper reset header, a floppy disable header, a 15khz vga sub d 15 pin output, etc.

As I am doing this in "Sprint layout" a software that is awesome for reverseing a PCB like this (just draw traces above a scanned picture) but editing is a pain. I will do very very little modifications. this is just to get a gerber. AND to verify the schematic is correct. (they sometimes differ against the reality.. like small parts of the 3640) so when this is done I might on next boored businesstrip do schematics in eagle or so. and from THERE do a completly new routing etc. but maingoal is simply to have replacementpcbs.

I have ideas of at RF area add a footprint for 15KHz VGA and also rework the CXA area to support a more modern version of it not needing those delaylines etc. we'll see there.

but.. replacement PCB and gerber that will be the maingoal (YES! I will release all files. even the sprint workfile)

AND this is the 1D.4 revision as it was that board I got a good 600DPI scan of a bare board. :) meaning we will have data to follow traces etc. mabe guys behind pcb explorer can use that sometime. :)

Chucky where in GBG? Can I hand over some mobos for fixing :-)

Djole501 14 June 2018 12:29

This is very interesting, i would very much like at least one board. Good work!!!

So far.. :)

Very nice!

There have been so many PCB's designed recently it's like a new golden age. I knew the A1200.net case would come in handy eventually.

A500 motherboard next please. :p

jediknight 15 June 2018 01:39

can i buy one first on list thanks.

modrobert 15 June 2018 06:00

Thanks for doing this Chucky, impressive work. Is it a four layer board?

BTW: For those interested in populating an empty PCB, are the components still available? Assuming some are hard to find.
