    Tri-booting advice

    I don't know IcarOS (Google let me to fitness machines) so I don't know if that order of installing the OSes will work. If it won't, use a boor manager.

    Ruud's Diagnostic ROM

    And what was the problem? AFAIR I always used a third party MDA card so I never encountered the bug. I just checked my old sources and outputting 00 is the first thing RDR does at a reset, after executing CLI. So I really, really wonder.

    Ericsson Portable PC type 8400-005

    Thank you very much! I have had a good look at the motherboard but AFAIK I haven't seen any battery, so I doubt it. Maybe it is a tool to set the clock speed? But I cannot remember that I saw another crystal or oscillator but that can be overseen. I cannot promise you anything but I hope to be...

    I advice you to place a request in the "Wanted" thread. Much more chance IMHO.

    If there is bad RAM present, then, unfortunately, you have to take the whole machine apart. It took me some time to find out where to start: you have to remove some plastic covers at the top of the machine. From there on it is easy but still a lot of work. Having no intention at all to use the...

    Oops, I just send an email using the "Contact" of your museum. Wanting to thank you I just realized that you are the Mattis that I sent the mail. Of course I want the manuals. I hope to find out more about the RAM disk these machines have. I also hope to find out if it is possible to upgrade...

    ServerWorks and Win2K Server

    Small ones: maybe. Big ones? No, the point load would become to high and can damage the floor.

    Commodore PC40-40 repair, mainboard is a PC/900-2, PB85065-(I)-2F

    That's indeed a complete different board and I have never seen it. Regarding the badge differences: I almost consider it normal :)

    Commodore PC40-40 repair, mainboard is a PC/900-2, PB85065-(I)-2F

    No, not really. You have various types like the PC30-III, PC35-III, etc. Have a look at Bo Zimmers' site. They all have the same board. But some boards have onboard VGA and others have not. A good example is this PC30-III board but clearly shows the text PC40-III at the bottom-right between the...
