Paul — the image is from the SIMH RT-11 V4.00 software set. There’s something like 150 files on the disk.


John — the SLUs are at what I think are the standard addresses and vectors (per the Heathkit and DLV11-J manuals) and the ODT and TU58EM work. I don’t know what RT-11 is looking for but the console @ 177560/60 and TU58 @ 176500/300 (Channel 3 and Channel 0 in DLV11-J parlance). 

I have not tried booting SIMH with the TU58 image (not sure how to do that; need to work on it). 

Regarding getting a real RX01 or RL02, the issue for me is space. It’s pretty convenient using a laptop and TU58EM (providing I can get something other than XXDPD2D to work). If someone has already built bootable TU58 RT-11 images, I haven’t found them yet.
