Hello, everyone. I have, as of two weeks ago, finished designing what I assume will be the smallest complete MSX ever made. This is just the first of a series, and I made it to test my capabilities. Well, yesterday the boards arrived, so now I just have to wait on a few components to begin assembly. It will be compatible with KdL's OCM-PLD. Board is a wee bit bigger than a floppy disk (10cm square).
Here goes:

Very nice and compact board. Can you show the lower face of the board?

Don't have the board with me right now to take a pic, will post one soon.
Ports are:
2x MSX bus slots
2x 9pin joystick/controller
2x USB
PS/2 keyboard
microSD slot
VGA (capable of both 15 and 31KHz)
Composite Video
Stereo P2 audio output

The first revision uses an EP1C12, but this is quite probably gonna change for future versions.

No cassette port? It does not conform to MSX minimum specification! Just like the TurboR does not have a cassette port? Looking good by the way Wink

Hi. Did you previously used the EP1C12 in a development board? If so, could you tell wich or send a link?

Thanks for all your comments so far!

No, no EP1C12 dev boards were used.

Well, I'm aware I would technically not be complying to the original standard by omitting the datacorder port, but I based myself on the fact that neither the OCM (which is an official MSX product) nor the tR have one, so...
I know about the MSX that is the size of a konami cartridge, but that can barely be used on its own, right?

Anyway, we have a few GPIO left for that, should the need for a cassete port arise.
