Rare MSX cartridge...

I have just googled a bit. It appears in this catalogue as an accessory for transceivers :-?

Unfortunately for you, nobody knew this cart and I bought all stuff from yahoo auctions
Many thanks to Takamichi!
We have rom dump too, stay tuned!

With this cart you can connect Ham Radios http://en.wikipedia.org/wiki/Amateur_radio to the MSX, and transfer files to other people. CALL commands in firmware!

Wi-fi was already invented for MSX (and Apple) in mid 80s!

Also, MSX-FAQ lists another unknown cart... well I think I've got it, it's a card reader.
I think it is the last on this list: http://www.faq.msxnet.org/hardware.html#Toshiba
but I don't remember it has a cable.
So this evening I will check.
I suppose there are more devices from Toshiba: I read a article on a old magazine about cooperation between Toshiba and public Italian schools, mainly in communication / modem field.

I'm sure some software exist somewhere in the net. I know some user made MSX-Basic programs, too.
I'm waiting to receive carts, so I'll do some experiment.

It is a cartridge for use with "CAT" functions in the transceiver. CAT stands for Computer Aided Transceiver, and is simply a way to control remotely via the computer all the radio functions, without the need of using the built-in menus or buttons of the radio. It is interesting nonetheless for the memory management of certain scanners, but nowadays the cat software has improved much more and the usage via mouse is more adequate. Would have been interesting if it was a packet or rtty cartridge, because on these modes, you can actually swap information and data between computers, as the cat is only useful for controlling the radio. Is there any dump already of the roms?. Would be interesting to check in emulators and see how it was in those times the cat control.
