Talk:Sun-2

Sun may have made a 4 Mb Multibus memory board. I find an reference to 4 mb memory board with a Sun part number 501-1232 in a posting by James E. Carpenter on the Sun At Home mailing om 7 May 1995list.

Sun kernel config file in 4.2BSD
Today I ran across a Sun kernel configuration file in the 4.2BSD source code that is on the CSRG ISOs. Those CDs were produced by the team at the University of California at Berkeley, Computer Science Research Group and are sold by Marshall Kirk McKusick who was part of that team. They should be pretty reliable sources of what BSD was like.

The file is 4.1c.1/sys/conf/files.sun. A "files" file is used by the kernel config program and it contains the names of files and directories that make up the kernel.

4.1c.1/sys/conf/files.sun is only 38 lines long while the ones in SunOS are over 100 lines long. This could indicate that it is much older. The date on the file in the file system is Nov 4, 1982. The contents has directory names like sundev and sunif which real SunOS has. I don't know how or why it got there.

I think that SunOS was created this way:

VAX 4.2BSD pre-release -> modify 4.2BSD to be SunOS on VAX -> cross compile to Sun2 and Sun3. Jamplevia (talk) 01:38, 23 May 2023 (UTC)
