A4000+ Alice motherboard DIY
« on: March 27, 2018, 08:27:27 AM »
Let me introduce you to the A4000+ Alice rev1 motherboard.
A4000+ motherboard is based on the Amiga 4000cr motherboard designed by Commodore.

I have been thinking for a while to do some Amiga hardware and decided to start with a relatively easy but laborious task, an Amiga 4000cr motherboard.
I didn't have a blank A4000cr motherboard PCB nor any high-resolution pictures of a blank PCB, so I had to layout the A4000+ PCB completely manually.
I used a fully working A4000cr motherboard as a reference.
The PCB dimensions and all component locations, hole locations, hole diameters, solder pad dimensions, component silkscreens, etc. of the A4000cr motherboard were manually measured and transferred to the PCB design software.
I draw the line at the PCB traces, those I didn't attempt to mimic from the original A4000cr board.
The PCB traces of the A4000+ were fully manually routed (which too ages).
The result is a quite close replica of the original A4000cr motherboard.

Here are a few pictures of the blank PCB.

The next motherboard that I'm working on will be something completely different.

Impressive.
Are you going to do anything with the design files?

WOW!!! Very impressive!  

Can't wait to find out what the next board is...

I assume the 4000+ board would work with Chucky's A3660 accelerator board?

Wow! It's amazing when something as complex as this pops up seemingly out of nowhere. Much better than boards that get talked about for years but never happen, haha. ;)

This should certainly help resurrect a few A4000's that have suffered battery damage (assuming you decide to sell or otherwise produce additional boards).

How about for a "phase 2", incorporating some of the more common A4000 motherboard mods, such as PIO2 and 64MB of RAM mod? :)

This is AWESOME!!! How can one person manage to accompish such a beautiful thing and like no one even knew about it? You should maybe consider massproduction of these babies? Maybe Individual computers will be interested?

Great modified version that is ATX layout would be cool A4000 are so dam expensive to buy. If one could buy a board fully assembled ready to fit in standard ATX case that would be wicked. Or even the new A1500 checkmate case
