It would be a good thing to get the contents of working ones archived. That's been my experience thus far... It looks like Christian Corti's worked out how to do this, but I don't know if he's made the archives public: http://computermuseum.informatik.uni-stuttgart.de/dev/ibm_5110/technik/en/i… The 5120 ROS is identical to the 5110 as far as I know. I don't know how applicable the above is to the 5100, I assume it's a bit different (and I don't have one to try it out on). It'd be nice to know what chips correspond to what portions of the ROS tests -- I have two bad Command/Language ROS boards from the two 5120s I have and they fail diagnostics in different places. I'm sure I could make one working board from the two if I knew which chips were bad on each one. It'd also be fun to find some software for this, but I haven't tracked any down. - Josh
