How is the software / firmware / softcores side of things progressing?

Update:
The PCB house has made a mistake with the impedance control in the board. They found this during testing and have almost finished re-making the first 60 boards.

It's not going to delay us (any more) as we are still missing the DACs....

Firmware is progressing. I am working on correcting some compatibility issues with the soft 68K core at the moment.

A shame to hear about PCB mistake but very glad to see progress still being made.

Looking forward to the release Mike. :)

This, ladies and gentlemen is what the option "Electronic Test" is for when you order a PCB run.  (I think)

Isn't that just for continuity?

The boards are 100% electrically tested for continuity.

This PCB has controlled impedance on all layers, so when they make it they also do a test strip. The spacing is calculated by me and modified where necessary by the PCB people to get my desired impedance. After production they test it to make sure the boards are in spec. Sadly in this case they used the wrong layer stackup, so the boards were slightly out.

It happens, they have fixed it. No problem.

After reading part of this thread I still cannot understand what exactly is this. Is this a board for the MiniMig to have AGA support? or it is a board for the A500 to have AGA support?

I'm under the impression it's a completely new Minimig with AGA - not an add-on for existing Minimigs.
 
A sort of Mega-Minimig.

its neither.  im pretty sure its a board that was developedd for something else that has had the minimig core made for it with extra stuff that this board allows.
 
Believe it was is developed as an arcade machine emulator, specfically 1942.   Might be way out here though

An A1200 equivalent stand alone. It can be programmed for different arcade systems I understand.

It's basically a retro 'machine' emulator.  It can be many types of system, what is of interest to us is that it might turn out to be a faster, enhanced, bug-fixed version of the original AGA machines....

Sheesh, people.  This system has been on the boards for a couple years now.  Go to the source if you really want to know more about this board.

Thanks Ferrellsl.

I've attached a pic of the new PCB. I haven't actually got it in my hands yet though.

Basically the board was designed as a general platform for my retro projects, arcade games and computer systems.  The Amiga core is ported to the board and I will maintain it. Jakub is working on AGA enhancements and I'm working on testing the soft CPU cores.
