Milan (Atari compatible) running NetBSD/atari 8.0_BETA
https://twitter.com/tsutsuii/status/957062304398426112
As Ebihara-san wrote, I've been working to revive Milan support
since I received the board last December.
Now NetBSD/atari -current (and patched 8.0_BETA) on Milan
reaches single user.
I'm really glad to see Milan kernel actually working even after
major MI API changes, like the following threads :-)

http://mail-index.netbsd.org/port-atari/2008/12/thread1.html#000184
I would like to thank Julian Coleman and Leo Weppelman for providing
their Milan board.
Current status:
- only 16MB RAM is works; see the original leo@'s post back in 2001:
http://mail-index.netbsd.org/port-atari/2001/06/07/0000.html
- S3 Trio64V VGA console works
- 3c905-TX with ep(4) at pci and 3c509 with ep(4) at isa work
- bootloader also works
(we should prepare link wdboot from sdboot for milan)
- something wrong around ISA interrupt and it hangs on
heavy disk/network load
- no interrupt on secondary IDE (maybe firmware issue)
TODO:
- probe whole RAM on all four SIMMs
(needs info about physcal address mappings)
- rework ISA interrupt dispatcher (how to defer IPLVM interrupts)
- test more PCI devices including bus master DMA
dmesg (patched 8.0_BETA):
