Maybe but you're obviously motivated and intelligent.

I'm sad that dosbox 0.65 was buggy. It was real stable here. Thanks for mentioning your OS. My only problems with dosbox were on it2007he. (hacker edition). Can you write an email to the psion emulator developers asking if they would consider making an open-source/linux version?

Update on the 0.72 build: the dosbox developers gave me a video mode testing app, and i could identify vga/ega modes that were causing problems. Not all of them do.
