Here's the rest of my post: ... Hi Clive, What you've built so far is awesome. For your Backplane, I'm assuming the middle 4 connectors are standard MECB (for any MECB Cards), and just the two labeled straight female connectors at each end (i.e. connectors 1 and 6) have the custom connections for e...

Thanks Greg. I was using Google. I went and joined Imgbly and that didn't work either so I tried the attachment method. This works but it wouldn't let me have more than 3 images per post. So I cut the post in half and reposted it as a part 2 ;) Thanks. I've further update my Including Images in you...

Nicely done. I see the old and new designs have a different port placement on the PCB, am I right? No changes to the port placement. The only port change was to the silkscreen labeling of the MD2 Video Output, which I changed from "RGBS" to "Video", as a more general term (to al...

... Well I experimented with putting a TMS9118 on to your Video card. Here it is: ... You have been busy! Firstly, let me say how awesome it is to see your post! You really have dived right-in with what my core intention was, with documenting the MECB system. That is, to provide a modern standard f...

Welcome! It's interesting how many of our own stories are very similiar in regards to getting started with our first 8-bit processor in the late 70's or early 80's, having awesome experiences with the challenges and huge potential of this new technology, only to have life / careers take over our ava...

Just updated this topic to now reflect v2.0, and I also added a link (above) to the latest blog post & video covering the v2.0 Update!

and... I'm pretty sure it was you who inspired me to add reset headers to my CPU Cards.

I built a composite output version of the TMS VDP for the Arduino a while back and even got a basic version of Space Invaders to work on it... That's awesome. Some fine work! I hope to have some Space Invaders running across the screen on an MECB system in the not too distant future. Of course, I'l...

I was playing a bit with the graphics card yesterday and managed to convert the plasma code from Matt Sarnoff's page Nice work! I seem to be too involved in hardware at the moment, which is taking my attention away from coding. I might have to look at his asteroids game as well to see if I can port...

I've just updated this topic (and the above post) to reflect v2.3 as the current version. v2.3 update fixes a minor oversight in the v2.2 design, and also adds a Reset header to allow easily connecting an external reset button. The v2.3 update is detailed here: Minimalist Europe Card Bus (MECB) - 68...
