Just entered mainlne, already 404 :-(

Is http://sysam.it/cff_amcore.html the new (and future) URL?

Thanks!

Cool!

I really enjoyed your presentation at ELCE. Thanks!

many thanks, really, i hope there will be chances to meet us again.

I am working now on a "stmark2" board, mcf54415 based, quite all BGA.
In first prototype soldered here (infrared) BDM works fine,
i can debug some initial code from SRAM in a very responsive way.
Unfortunately for now i am stuck with P&E / CodeWarrior tools,
but will look for a better open way once things works.

Best regards,
Angelo Dureghello

I'm planning to come. Let's do some m68k hacking. I would like to get
the installed packages count to over 10.000 and fix debian-installer
on m68k to create new installer images. We also need to get EMILE
back in.

Once i'll have my mcf54415 based board up and running i should be able
to contribute to debian as i can. I'll let you know.

well for me is a bit hard to come due to family things, but who knows, the fact
there are no attendee costs and reservations to do keeps the chance open for me.
