The device had an interesting collection of storage options.
*4MB (yes MB) of onboard flash.
*A 2 Type II / 1 Type III PCMCIA sot. PCMCIA cards are physically gigantic by today's standards. There are adapters to put CF and/or SD cards into PCMCIA slots, so, with the right adapters it could theoretically handle, very slowly, two 512GB SDXC cards.
*Pico/Mini Flash card slot. Good luck ever finding a card to fit this very short lived and unobtanium standard. It was about the physical size of a modern SD card. I understand that it was a bootable media.
*A docking station with a floppy drive in it.
Note that it predates USB existing. It predates WiFi. It predates Bluetooth.
It has a wired modem compatible with the Japanese phone networks of the time WITH voice capabilities to use it as a wired phone answering machine and speakerphone.
Stereo speakers.
Getting data on/off this thing today is pretty much by physical media or, if you have a docking station, potentially through the RS-232 serial port that only exists when docked.
Back in 1996 I had the opportunity to buy a brand new one for $1400 and passed on it. That is $2200 or so in today's money. I see this machine as the spiritual predecessor of the Pandora and now Pyra. Super compact, clamshell, LOTS of storage options for it's time.
The last time I saw one on Ebay was about 6 years ago. It went for right at $950. The floppy dock port replicator sold separately got $450.
