It is. Check the "DECstation/DECsystem 5000 Model 200 Series Maintenance Guide" (EK-PM38C-MG-002), available online. > Also, can anyone tell me what the jumper on the > base board under the leftmost TURBOchannel slot might be (on the left when > looking from the back of the machine)? Technically it's wired to one of the 16 IOASIC external interrupt inputs, which is otherwise unused. Functionally it tells software whether the mainboard is used in a 5000 or a 5900 system configuration. I can dig out the exact details if you're interested. BTW I saw your 5000/240 web page and I'm glad that you have rescued all that fine hardware. Also I think you don't have to worry about the H7878 PSU -- apparently none of the caps used in that model suffers from the dreaded quaternary ammonium salt issue. Last not least, I don't keep up with mailing list traffic, so for a shorter RTT please feel free to CC me on any DECstation stuff. HTH, Maciej
