                     42: The KAP processor used in the IDT systems, albeit using an instruction
1.4       jsg        43: set similar to the SPARC processors, uses a completely different MMU.
1.1       miod       44: Because of this, no free operating system considered running on these Solbourne

                     49: had no excuse not to work on a port.
                     50: After a few years of procrastination, real work on a port eventually started in
                     51: march 2005, leading to an initial import in the OpenBSD tree exactly one month
                     52: later. And work continues...
