But the SVR3/88K kernel was a heavy rewrite. LCC did a lot of work with DG adding stuff too it -- it was very well done by the DG team in NC. The memory and FS was well integrated. Of all the UNIX kernels we did work, it was pretty much the easiest to learn and modify. =E1=90=A7 --0000000000001bb33305ed49d813 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable
