For the full changes you can look at the Mercurial version history, but I expanded on ports F3-F7 and the list of switched I/O ports manufacturer IDs, and resolved some of the things I had marked at questions, e.g. removed the MIDI Saurus listing for ports 0-3 (as the Datapack says it’s at 70-73), and corrected / clarified some names such as MSX INTERFACE.

Indeed I suspect B8-BB might be that Yamaha card reader indeed. Have to confirm sometime.

Re. Sensor Kid, I assume you know because it’s emulated by openMSX? (Just need some confirmation or source before I add it.)

It's not emulated yet, but it's emulated in some patch based on zodiac. Sylvester ported it to openMSX, but it's not committed yet.

AFAIK, the maker ID 26 is in fact Samsung, but there was a typo in the technical handbook.

About #B8-BB ports, the Bee Pack can not use these ports because there is only one chip 74LS00 inside.

I think Softcard adapter use a similar system and only the connector is different. It is unlikely that use I/O ports. Perhaps it is a flash card interface. MMC/SD Drive seems to use ports #B8~B9.

Nevertheless the page below says that the #B8-BB ports are also used by Sanyo's light pen interface. This is correct.

#B8~BA is an I/O. #BB is an output only.

Thanks Smile. I’ll just remove the speculation. Light pen interface is already listed underneath it! Smile

Tip: The I/O ports overview page doesn't list the NMS-1205 2nd DAC (Covox-like) at (AFAIK) I/O port 0Ah.
