MikeOS - simple x86 assembly language operating system
Pavel "Sonic" Fedin is still working on the Windows Hosted version of AROS and, in the course of this work, is also trying to solve several problems in the way AROS talks to the hardware, in order to abstract it; this led to his modifying components that require an abstraction layer in order to work in hosted AROS versions, such as file systems and hardware; this includes a packet handling method for SFS. Also, Pavel, together with Jens Langner, is trying to cross-compile the most up-to-date versions of the mcc.BetterString and mcc.TextEditor MUI classes so that they will be taken straight from the mainstream source instead of being included in the AROS source tree. Matthias "Mazze" Rustler has released an alpha version of the Ignition spreadsheet application. At the moment data cannot be saved but it is still a good occasion to have a look at this application, underestimated on AmigaOS but quite powerful and well realised.
