Portfolio to USB adapter stack:
- Portfolio Serial Module
- Gender Changer
- Null Modem adapter
- RS232 to USB adapter
I can send and receive files on the Portfolio via xterm2, on my modern PC I use TeraTerm to communicate with xterm2 over serial using the XModem protocol.
I also wrote an image converter to convert jpg to pgf (portfolio graphics file). I haven't yet implemented the compression to write pgc (portfolio graphics compressed) files directly. I use pgcompress on the atari to convert pgf to pgc. Pgc files can be viewed on the Atari using pgshow.
I got all software for the portfolio from here: Portfolio Library
Let's say: It's really tiny, as is the whole device.
But well spaced keys, just still suitable for some kind of touch-typing even with my rather large hands.
The keys feel somewhat similar to the high-end calculator I also owned at the time. (HP G48)
Source: Used one during university. Really great to document lab results with its build-in spreadsheet app. Cut down the required time by half or so.
I can see how the spreadsheet app would be killer on this with that screen shape!
