i had to admit, i'm not the best informed member here. But the home pages of medusa computer systems (http://www.kingx.com/kingx/medusa/thes.html
) and the milan side (http://www.milan-computer.de/de/news/index.php3
) have no actual news. So i gess there is little or no hardware development at the moment.
TOS itself is not longer under any development. But there are some really interessting alternatives (which are at least compatible to some degree):
), a freeware TOS with some additional features (harddrive support). It was updated several times this year.
MagiC: No new version for some years, but Application Systems Heidelberg is still selling this OS.
Not to forget, some very good emulators are available:
STEEM and Saint (ST/STE), aranym (Falcon), MagiC PC and MagiC Mac (MagiC). So you profit from new PC/Mac Hardware, too
