Here is a useful English document:

the device is somewhat compatible with legacy pokecoms. Documents for those older Sharp Z80 pokecoms can be useful for assembly programming. I've never gone any deeper tho.

Very nice reference link. Thanks! I have a half-finished PIC burner board based on the design in the second link (I keep getting distracted by other projects!) I have a link to a second, simpler PIC burner design I found on a Japanese BBS that I can post later.

The serial port works as documented, but the Sense/Mark levels are reversed, so you get nonsense on a USB to TTL Serial interface. An inverter would fix that. It also seems to send a long Break before transmitting data.

Lack of documentation is the biggest catch. I've yet too see any of the TAS sellers include a copy or a link to the user manual. As andylithia mentions, it's close enough to some of the earlier models that you can find user manuals online that help with its built-in BASIC and C. I wish I could find more programs and such for it, but relevant Japanese web sites don't turn up often in my regular Google seaches.

If you get one, expect to spend time taking notes and learning to use it. Imagine if the TI Voyage 200 were a discontinued niche product that no one bothered to save documentation for!
