RSX-11M trouble

[supervinx]

Well... the only indirect command processor present on RSXM70.DSK was
ICX.TSK
I transferred it from simh RX50 disk image to a RT-11 formatted floppy
with PUTR (copy /binary) and then with FLX

FLX> DU0:=DU1:ICX.TSK /RT

Then 
> REM ...AT.
> INS $ICX.TSK
>@[1,2]STARTUP.CMD

and got a BIG system crash

So they are definitely not compatible.

I've got a 4.2 RSX-11M plus tape set.

I'll try to install it on simh and see if they are binary compatibles...
