Hi, we got a Zilog S8000 this weekend. The system is really nice and in good shape. Thanks to Oliver Lehmann, there's a bit of documentation for this system (seems to be very rare nowadays). Our system had several errors during bring up diagnostics that were caused by bad contacts in several IC sockets (could be cured by pulling out all socketed ICs and reinserting them). But there's one error left, and alas, our system is a Model 32 that is a bit newer than the Model 31/31plus, the CPU board is different and the error number is not in the hardware reference manual. The system also doesn't boot successfully from the SMD disk, it is able to load the primary bootstrap, but trying to load the secondary bootstrap immediatly returns an error. Here's what comes out on the terminal: System 8000 HPCPU Monitor 10.1 - Press START to Load System MONITOR POWER UP DIAGNOS *** ERROR #0402 <03> 3600 3600 5555 TICS ACTIVE PERIPHERALS: SMC TCC SSB0 COMPLETE MAXSEG=<3F> *** SMC ERROR [ Question: What is error 0402 ? Did in the meantime more documents or even tapes (ZEUS, SADIE) show up? Some first pictures can be found here: http://computermuseum.informatik.uni-stuttgart.de/pics/s8000/ Christian
