[HECnet] Looking for VAX 8600 Diagnostic Supervisor (EDSAA.EXE)

I've been working on rewriting parts of the VAX simulator(s) to avoid some of the undefined behaviors that the C language has relating to overflow and shifts of signed integer values. Changing the details of how instructions are implemented comes with the non trivial potential to break more things than are being fixed. To manage this, I've been trying to use the basic CPU diagnostics that DEC for the systems being simulated. I have found the VAX Diagnostic Supervisor for the 11/730, 11/750 and 11/.780. I'm missing the VAX 8600's diagnostic supervisor. If someone knows where I can find a version of this file it would be helpful. Thanks. - Mark
