I have a diskless 3/50 which drops into the debugger near the end of bootstrap: starting system logger, time daemon fpu_emul_type0: unknown: opcode=0xf200, word1=0x4100 Stopped at 0x7d68: fmovl d0,fp2 I presume that the problem is that the machine has no fpu. The config file has option "FPU_EMULATE". Is there another option I must invoke? Tom Calderwood
