In a previous life, I worked as Unix sysadmin at university. We had several old Sun3 (motorola 68020 based) and a few Sparcstation based on Sparc. The first SunOS I worked with was 4.1.1U1 and the last 4.1.4. I remember even the 68020 were a bit unhappy with 4Mbytes of RAM but I can't recall if it was a kernel requirement or just the userland stuff we needed to run on them. Probably NetBSD can be a more recent and configurable option for embedded sparcs. best regards Frank _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
