I do several experiments to get a bit more HDD space for the #TurboDOS in the #KneisnerM100. My attempts some time ago were not so successful, but I had an idea last night.

What a great day, our #Kneisner #m100, a German #Imsai8080 clone, has made it's first boot without a loaded diskette after a few seconds of waiting.
For testing purposes I used a Seagate ST-225, which full capacity isn't used at the moment. I've to figure out how to handle the drives parameters in #TurboDOS reasonable. Maybe it is impossible, but does not care at the end.

After over a year of continuous investigations, tests, measurements, repairs and absolutely active help from the USA, our #Kneisner #M100 is now booting #turboDOS from a floppy disk.
It still has a few quirks with its front panel. But the next step will be to try to boot it from D.Gesswein's MFM emulator from a known working HD image. To see whether the WD hard disk controller and the IMS controller card are still working properly.
The whole thing is now a "once in a lifetime" project for me. What I wasn't aware of until now is that the #IMSAI8080 will be 50 years old this year.
