From Bill Cattey: Adventure: advent.tu56 BASIC Games: ba.tu56 FOCAL69: focal69.tu56 MUSIC: music.tu56 U/W FOCAL: uwfocal-v4e-1.tu56 uwfocal-v4e-2.tu56 OS/8 V3D with patches: v3d-td12k.tu56 OS/8 V3F (Intermediate build from source. Has rx02 driver and other goodies): v3f-td12k.tu56 The last two are td12k bootable images. They will run with your hardware. I see you have the MR8E TD8E boot ROM. Although my scripts try to build with the tdrom driver, there is no MR8E simulation in SIMH so when I boot into the image halfway through the process, it just hangs. You can take the td12k images and just use BUILD to switch to the TDROM system device.
