You can't take the default on *all* questions, since some don't have ny defaults. The CSR and vector for the terminal lines, for example... :-) You're right - I did have to enter the address for that one. Simh is rather simple minded about the terminal muxes - it considers the DZ11/DZV11/DZQ11/CYX08/CXY16 all to be the same. Although the hardware is different as far as I know they all have the same programmer model so this is not unreasonable. The only thing that differs is the number of lines per board, and simh allows you to set that. And the only floating vector in this configuration, AFAIK, is the DZ/CXY and 300 is the first one, right? FWIW I did a VMS SYSGEN (which, among other things allows you to enter a list of devices and will calculate for you the correct CSR/vector assignments) and it agrees with simh in that regard. It particular, it says 160100 and vector 300 for the DZ11. As far as I know the PDP-11 and VAX rules for address and vector assignments are the same, but it's possible RSX does something different. It's suspicious that the default answer for the first DZ11 in the RSX SYSGEN is not the same as the default floating address assignment. The other devices (MSCP disk, MSCP tape, NI) are all their default addresses for the first such device. You really need to make sure your hardware is correctly configured before you can expect ACF to work. Sure, but that's the whole question. I think this is the correct configuration unless you can see what's wrong. The other possibility that there's some hardware in there that this version of ACF doesn't know about. I guess I could do another SYSGEN and just take out the DZ/CXY from the simh configuration. That's easy enough to do. Bob
