Nigel, I’ve been trying to find a working distribution for PDP-11 Saturn-Calc and Graph for some years now. I had a licensed copy many years ago for RSX11M but it no longer works. I do have a working copy of Saturn-Calc and Graph (but not WP) for VMS on my MV3100-80 but not the VMS distribution. I have managed to contact the lead programmer that developed Saturn’s software through a former president of the company. The programmer believes he has a copy of the source code for PDP-11 and VAX on a CDROM that is in a storage unit. He has retired overseas and come back home where the storage unit is a couple times a year and I’m hoping he can find the CDROM on his next trip back. I can keep you posted on our progress in trying to recover this software. It helps that the programmer is interested in making the Saturn products available as it may need to be recompiled or at least relinked to be compatible with the newest versions of PDP-11 operating systems with Y2K etc. We thought we had it recovered a couple years ago when nine RX50 floppies were found in Australia that were from a distributor that could be used to generate new customer distributions, but there was no documentation and some info was missing. Also, manuals for the Saturn products have not been scanned so we are looking for them as well. If you had some specific Saturn Calc spreadsheets that you wanted data extracted from, I might be able to help you with my working VMS version of Calc. Saturn Calc was a great product that we used a great deal back in the day. The Saturn Graph product supported VT340s with the mouse and could generate plots a wide variety of HP and other plotters, printers, etc. Best Regards, Mark
