This is an A4000+ Alice PCB, it is an Amiga 4000D CR (cost reduced) motherboard replica and it was created by the talented Hese who made some awesome Amiga clones and hardware available to the community. If you are interested in buying an Alice A4000+ PCB, check out this thread on AmiBay (not sure you can still get one though but maybe one shows up second hand).

This was supposed to be my summer project of 2025 and I could not resist to share it on my blog even though it is not 100% finished yet. It took me about 2-2.5 months to reach this state as I was in no hurry during the summer to finish it. It is almost finished, just missing the DB slots, battery holder, two sockets and an electrolytic capacitor. Oh and all the custom chips off course, but I have a full A4000 chipset sans Buster and Ramsey…

A full socket Amiga 4000D motherboard build

The reason I did a full socket built was that I was thinking it could come in handy if I would need to test custom chips in the future. One of my A4000TX was built with sockets, but I did a bad job, cutting out the center sections from the sockets before soldering them. So I want to convert the A4000TX to soldered custom chips and have this one as my primary testing station (or primary A4000D motherboard, nothing is static in this hobby).

The other reason I did a full socket build was that there are quite a few projects around where users are looking into cloning the custom chips. Most of these solutions are using a PLCC plug that mounts in a PLCC socket, so if everything goes as it should go, perhaps we can have full custom Amiga chip clones in the near future! Woops, better sell your stash of Buster 11 while you still can get 150+ euro for them!

On schedule and rocking + two more weeks!!!!

The A4000CR is an interesting motherboard as it is slightly different than previous A4000 motherboards. There is a 030 on the PCB and the chip memory is already soldered to the PCB, thus it only has four memory slots in comparison with previous revisions of the motherboard.

And once this is finished, I have a beautiful red Acill A4000D motherboard to build, perhaps my next summer project?

Can’t wait to fire up this beautiful blue Amiga 4000D motherboard in a month or two (sorry I meant: week)!!
