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

?KMON-F-Illegal device LP:
.R MUBAS
WARNING: DATE NOT SET

PLEASE TYPE IN "HELLO".

Hello all,
I would like to try and get MU-BASIC working on my PDP-11/45, under RT-11
V4. The best bits I've been able to find to work with so far are the RK05
image here:
http://bitsavers.trailing-edge.com/bits/DEC/pdp11/discimages/rk05/rt11v4-mu
basicv2.rk.gz
...but I've not had much success getting this to work under simh. Using the
1USER.CNF configuration file in this image, no matter how I configure the
machine, I get either traps, halts, or stack violations when issuing the
first command in basic.
Trying to rebuild MU-BASIC using the indirect files in the image results in
a linker barf on some undefined symbols.
Has anybody else here had much luck getting MU-BASIC up and running under
RT-11 V4? Is there an alternate image or distribution kit somewhere that I
could try to work with?
thanks much,
--FritzM.
