Emax

Hi there,
after long time, after seeing lot of discussions about scsi, I decided
to open my Emax SE and check for an upgrade.
It is a pc board 333 rev. A and it has the IP356 PAL already mounted
on the board.
I miss only the scsi controller chip NCR 5380 and the boot eprom IP355
(an IP349 is onboard).
I can pull the NCR 5380 from an old mac, so I desperately need the
boot eprom.
I saw the eprom is a classic 2764, easy to copy. Also the bynary for
me is enough, I can program the 2764 by myself.
Can anyone help me with that? 
Of course if someone has both the 5380 and the IP355 I will be happy
to buy together!
Thank you to all for your kindness.
Regards,

Patrizio
