Hi Pere, These disks are based on my own compilation of the NitrOS9 Mercurial source done about a year ago. Unfortunately, the current NitrOS9 source for the Dragon seems to create disks that aren't bootable (at least with my configuration). My complete working NitrOS9 disk set (CoCo & Dragon, 30 me...

Here is NitrOS9 v030209 for the Dragon 64 in VDK format (works on XRoar). There are 2 versions attached, one boots in VGD 32 column mode and the other in 51 columns mode. Note that the NitrOS9 51 column mode is not compatible with Dragon Data's go51 mode, therefore Dragon Data's Stylograph and Dynac...

Unbelievable.

On my Tano Dragon (Issue 2) the LM1889 is soldered. All pins seem to be in place.

Nice! One more Eurohard hidden gem discovered! The piggyback board looks quite simple to clone. Too bad that the 6847 is soldered on most (all?) of the Dragon motherboards. I guess Eurohard weren't that sensitive to copyrights :shock: . Eurohard OS9 also omitted the Microware copyright message on st...
