  1. One interesting exercise would be removing the original BIOS ROM(s) and try a generic XT BIOS instead. Maybe compatibility would go up, depending on the design of the machine, looking at what could be seen of the motherboard on the video, it looked like a standard XT board.

  2. The 80's was a fascinating time for computers. Some computers were specifically built for business usage because the business market was perceived as more lucrative.

  3. I'd really like to know if it's just their Sanyo BIOS that was IBM-incompatible, or if it was something else like an incompatible chipset or the like. I wonder if a BIOS/hardware hacker could fix the Sanyo's compatibility issues.

  4. I had one of these back in the early 1990s! One of the things that will improve the compatibility quite a bit is replacing the buggy Sanyo BIOS with a generic Phoenix XT BIOS. My brother and I tried it, and it fixed a lot of problems with both DOS and CGA compatibility.

    The odd floppy drives were Chinon, and I seem to remember them working pretty well.

  5. Just recently bought and Atari XL-600, so now of course now I need to get a XL-800 to not limit my access to games. Read somewhere the 600’s won’t load al the games.

  6. I have been looking for a newer one of these portables with a 486. I know they made them because I lusted over them in pc world magazines as a kid!

  7. I'm not sure if I would be surprised if that bundled productivity software only barely made use of the 16 colors… or if I would be surprised if it was actually very colorful (MacWrite-like maybe? I'd be interested to see that; I've always wondered what the earliest graphical word processors for consumer-grade computers were. So far all I can confirm is "either Windows software or GEOS software or the 68000 machines".)
