Hmm, then that is the reason to change the mode to 80 columns every time I turn on my 1chip. 
So, if this thing does not have a tape port or a Real Time Clock ...
Is this any good for cartridge games?
It does have a tape port:
DIP 3 - red cinch select
0 = data recorder input/output <--- Ohh Nooooo, now we can't complain about that anymore.....
1 = sound output (emulated sound only)
It has a clock, it just forgets the time after you turn it off. Then again, which MSX software doesn't work if the date/time is not correct? But yes, you can still complain about it, so it serves at least that purpose. Might be more useful this way even right?
why all this would make it unsuitable for cartridge games is beyond me though ...

Just make an autoexec.bas file on your SD card to set all the settings you like

Yeah, I did it when I had my F700 and I had to get a faster diskdrive, 60Hz, etc. It was no the faster way but as it worked I did not mind. 
Anyway, I was testing OCM and it surprised me in the good way, since I did not have problems with most of tested software.

Coolness factor.
This is cool!!

Not so cool ...
Thanks Manuel! DIP switch 4 worked for me!
BTW, your FlashROM card was the first thing I tested on OCM.
Nice to hear you use it often
Another question: I noticed that white colour with the composite signal is "uneven", its shades vary from very pale blue, greenish, yellowish. In VGA mode, however, it's perfect. Did you notice the same with yours?
I always used S-Video or VGA. I have tested composite video and you are right. It seems there is something wrong.
Different colors are shown depending on the place there is a white pixel. I tried other colors (red, green blue) and some parts of the letters are missing, like if there is something wrong with the resolution. 
I have received my OCM a few days ago and noticed exactly the same. Tested with two TV sets, white letters are anything but white. Not able to test the S-Video but the VGA seems ok. Is there any solution to this problem ?
You know, NTSC=Never The Same Colour . It's the drawback of the original japanese OCMs...
Use the VGA or even the RGB feature on the same connector.
