Hi all! Spent some serious time this evening with the RX02 drives: I managed to download the images of the SaturnCalc 3.0, Saturn Graph, and Saturn WP software to RX02 images. I think it's set right, can someone take a look at the images and see if they are good? Should be RT11 format, RX02 (of course), I recorded from both sides of the disks (they're double sided, hole punched by the vendor) and are at https://www.crystel.com/bob You should see the disks and the meta files. Let me know if they work, I need to get to bed. Either burn them on real RX02's or read them with a SIMH image. C Chris, I am very interested in Saturn Calc for PDP-11s specifically for RSX. I downloaded your floppies and will take a look at them soon. You mention that they are in RT-11 format. Do you know which PDP-11 OS the Saturn software was for. They had versions also for RT-11, TSX and RSTS. Later they had native VMS and MSDOS versions. There are images of RX50s for RSX Saturn Calc, Graph and WPS at Malcolm?s web site. https://avitech.com.au/?page_id=2570 <https://avitech.com.au/?page_id=2570> He also gave me some documentation that I have scanned and put up at http://www.rsx11m.com/SaturnInstall.pdf <http://www.rsx11m.com/SaturnInstall.pdf> http://www.rsx11m.com/SaturnCalc.pdf <http://www.rsx11m.com/SaturnCalc.pdf> http://www.rsx11m.com/SaturnCalcRef.pdf <http://www.rsx11m.com/SaturnCalcRef.pdf> Saturn products on the PDP-11 and VMS used their own license key systems. I do have valid licenses for Calc and Graph for VMS and have them running on a MV3100-80. It would be great to get the RSX version running. I used it extensively back in the day and it would be wonderful to preserve it. Best, Mark Matlock
