I've used that image quite a bit for testing my vhdl pdp11. So it should work.
>From a quick test, it appears as if the lpt device in the default simh config
conflicts. If I disable that, mubas works fine for me.
Like so:
sim> set cpu 11/45
sim> set lpt disable
sim> att rk0 rt11v4-mubasicv2.rk
sim> boot rk0
RT-11FB (S) V04.00E
.SET TT QUIET
?KMON-W-No date
00:00:00
?KMON-F-Illegal device LP:
.R MUBAS
WARNING: DATE NOT SET
MU BASIC-11/RT-11 V2.00R
CONFIGURATION FILE : *1USER
MU BASIC-11/RT-11 IS OPERATIONAL.
PLEASE TYPE IN "HELLO".
Cheers,
Sytse
