Hi folks,
I have a question about floating CSR allocation on PDP-11s. Both the 1976 and 1981
versions of the PDP-11 peripherals handbook indicate the floating CSRs are to be allocated
starting at address 760010. However, both the XXDP FLOAT program and simh's
autoconfig suggest I should set my DZ11 (first floating CSR device in my config) to
760100. Anyone know what gives?
thanks,
