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
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.

   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. <>

   He also gave me some documentation that I have scanned and put up at <> <> <>

   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.
