This is the procedure I sent to someone else on how to get it working. You can make a rk05 bootable versions with plenty of space with the following steps. Boot the emulator with rx0 and rx1 attached to the two floppy images and rk0 to a new file for the rk05 images and boot. .ZERO RKA0: .COPY RKA0:<RXA0: .COPY RKA0:<RXA1: .R BUILD $DELETE SYS $SYS RK8E $BO WRITE ZERO DIRECT?N SYS BUILT .RENAME PASS2O.SV<PASS20.SV Now you have a bootable rk05 image with all the files. The distributed image has the PASS2O file named incorrectly, it has a zero instead of a O. You will get a SY error if it is not renamed
You can make a rk05 bootable versions with plenty of space with the following steps. Boot the emulator with rx0 attached to the bootable os8_rx.dsk image, and with rk0 attached to a new file. The example shows creation of a new bootable disk for rk0:
.ZERO RKA0: .COPY RKA0:<RXA0: .R BUILD $DELETE SYS $SYS RK8E $BO WRITE ZERO DIRECT?N SYS BUILT
Now you have a bootable RK05 disk.
