DN10K

That sounds like you've got the basic compliment. As I recall from my days running a network of them, the base DN10K has four cards (Network, video, CPU and memory). Extra slots were available for an FPU, more memory (and maybe a disk controller?). The CPU should be easy to identify by the presence of a MC68010 chip. The DN10K's typically did not have their own disk drives; instead they booted (and paged!) off of a "partner" server node having the disk. The network adapters (in a plastic box that screwed onto the back) were spectacularly flaky on those machines. The DN10K's had a switching power supply with a subtle audible hissing/buzzing noise corresponding closely to the machine's activity. With experience, the power supply noise was almost as informative as a blinking-light front panel. For example, it'd make a distinctive rhythmic chirp when the network was interrupted and the paging algorithm was frantically re-trying the operation to clear the page fault. If not fixed ASAP, the screen would break apart with an ugly "PARTNER NOT FOUND" message. Between the flaky network adapters and the one-fails-they-all-die ring network topology, keeping a DN10K network running was challenging. Cheers, jp
