Atari Portfolio on Reddit
I’ve created a new subreddit /r/AtariPortfolio, dedicated solely to the Pofo. Atari Portfolio (and old palmtops in general) is barely discussed on Reddit. Once a few months you can find a mention on /r/retrocomputing, and that’s all. I hope this … Continue reading
DH’s hacks for the Portfolio
I wanted to post this months ago, but it seems that long winter breaks have become a tradition on this blog. In October last year, a reader called DH wrote a comment with his own proposition of a .com-file generator … Continue reading
The incomplete Atari Portfolio disassembly guide

DOS palmtops
Once upon a time, one of the readers, jerome, asked me to write a comparison of HP LX palmtops. While I consider it a little pointless (the 200 LX would take all the gold), a review of all then-popular palmtops with … Continue reading
Atari Portfolio as an e-book reader
You may think that the Portfolio is no good for reading books, but well, people read on smartphones (3,5″ backlit screen with tiny letters on it) or laptops (3 kg or so), so why not give Pofo a try? After … Continue reading
