SymbOS is running on MSXturboR with MMC/SD Drive.

Cool ! Would be nice if somebody will produce such a device from the customer's cartridge.
My soldering skills are not good enough to build it.

I'm not either good at soldering . Would it be possible for someone to get the responsability to build this hardware?. If I'm not wrong, it's the first "alien" hardware to be supported under SymbOS providing its own driver

The LPE-MMC is based on this hardware design, AFAIK. In fact I own it, I think Sapphire brought me it from Madrid years ago.

Could be posible to work with SDIO cards?

Now i suposse it works in SPI mode. true?

I have a f1 spirit scc,but to me it seems a little complicated to do alone and i am afraid i would kill a nice scc cartridge.Congratulations to the person who made this possible though!2 thumbs up.However because i lack the needed skills to do it i will probably go for a sunrise cartridge.

Best

So, is there anybody who'd like to make some money by doing modding for SCC cartridge owners ?

Anyone?

I talked some years ago with usuario_msx2 in a Barcelona MSX meeting about making an SCC+MMC cart. He made it by himself but thought it was better not to do it since it is too much complicated (too many small cables together ). So it is a bit insane to create it, I think nobody will do it for you. Instead of it you could get an MMC reader from Leonardo Padial (it is based on that Sharksym design). It is not expensive and all these cables are gone since it is built in CPLD. OK, you won't have an SCC there... but who cares?

hi is possible upload this img? the link is broken...
thanks!

A friend from Spain built this item as well

@Sharksym: Thanx a lot for the drivers. Great work! Sorry, didn't read this before, that they are available for download. If it's ok for you, I would like to add them to the download page of the SymbOS site?

Hello~
