Are you sure it's an 11/34? I once ran such a beast (actually >an 11/34a) and as far as I remember, having an 18-bit UNIBUS, it would >only address 256Kb. > I believe ABLE or some other company once made an MMU/memory upgrade for the PDP 11/34 that allowed it to go beyond the 256Kb limit. There are also two companys that sell J11 based upgrades for the PDP-11 Unibus systems providing more speed and 11/70 style MMU for running System 7 (?) or whatever needs seperate I/D addressing and 4 Megs of memory.
