wt808 (of mini 5200 fame: http://atariage.com/forums/topic/185369-compact-5200-system/) has designed a selection of cases for the EclaireXL mini. Several people are still tweaking/adjusting them though they are already looking good. He has posted it onto thingverse here:

Many thanks!
I just sent my first prototype case for the mini to the 3d printers. Lets see how it turns out...
I've plumbed anonymous svn read back into apache, so this link will now work again for checkouts:

Also fixed my backups which had been down since the server crash...
Happy New Year everyone!
Pretty slow days on the project, I've not been very motivated recently. This is cyclical though, sure it'll change again in a month or two! If anyone wants to spur me on by voting for a feature please do so in comments:-)
I decided to install/learn some 3d printing tools to make a cartridge housing. For that I decided to use Autodesk Fusion 360. Here is my first attempt that I just sent for printing. I'm crossing my fingers it works ok but I wouldn't be surprised if not!
I've just tried the pokey core on the pure digital chips. It works surprisingly well!
For some reason I'd remembered the keyboard 4051s were CMOS, so I didn't think the 3.3V output would work being <3.7v (http://www.interfacebus.com/voltage_threshold.html). However it works just fine, though perhaps not on all boards. Are the 4051s really CMOS levels?
The audio output is the raw sigma delta output, with no filter. However it sounds fine, perhaps relying on the normal audio filter on the main board.
Paddles do not have the correct voltage threshold, which is expected.
Less expected though is that paddle 0 works ok while paddle 1 completely fails. This one is weird. I'd connected multiple MAX10 GPIO outputs together so I could use multiple weak pull up resistors in parallel as a stronger pull-up! Paddle 1 happens to be on one of these pins. If I set them all to high impedance its pulled up to ~3v. Individual max10 pins work, together they pull high! Seems to be an interaction with multiple GPIOs at high impedance and the quick switches. I checked this on multiple boards to be sure. Weird...
I received a device to access the MSATA disk from my old server and am happy to report its all intact. I got all the old built cores etc backed up. I'll put them back online shortly, when I get motivated enough!
My Intel NUC, which I was using as a server stopped working last week. Its a shame, it was a really nice box from tranquil pc (https://www.expertreviews.co.uk/pcs/53515/tranquil-pc-abel-h2-review)
I've got a new machine installed and running now. I had backups of svn and redmine. I think those are now back in action, please let me know if you see anything missing.
Website is not backed up, but I think my ssd is ok. Just need to wait for a device that I can plug the msata ssd into... fingers crossed!
A little video from Nir, look at 35 to 42 seconds in for some new chips (and me!)

Working on antic... tricky since I need to know about dma/refresh for the following original cycle in order to set halt_n in time! Among other things.
A very simple, but hard to find, change this time!
Wizard of Wor was failing due to the code switching back and forth from poly 17 to poly 9 mode at precise times. This caused repeatable values from random, which crashed the game!
I added a 1 cycle delay to audctl bit 8, when enabling. This fixed the game.
Fixed a few small, annoying longstanding bugs.
