This may not be of much help, but if you could get ahold of an older ALR Revolution Q-4SMP machine, I think you'd be half-way home. Those old boxes lit up like Christmas trees, long string of lights indicating things like ISA bus interrupts, EISA bus interrupts, memory usage, disk usage, etc. Or, perhaps another way might be to find a NIC that has a connector for an external activity light and just have the machine ping out or another machine ping in on a continual basis. Given the speed of most LAN hardware anymore, that shouldn't be a significant hit, performance wise. --- Andy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
