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
Glitches like what? Sometimes all it takes is to run a warm soldering iron along the ribbon where it’s soldered to the board. Or anyway it works on old gameboys and calculators.
Missing lines at the bottom of the display… Just few lines. Maybe all it takes is just open that miracle and move the ribbon a bit. Getting old sucks, hands shake and you don’t trust your senses anymore…
