Good afternoon everybody. I will keep this brief, but I wanted to make an account to give a thank you to the Pegasus team, particularly Babatunde Akinkuolie for the excellent, thorough documentation on the knowledge base site for legacy Pegasus products, particularly here and here.
I have been a long-time Pegasus user, and still have my original Pegasus R4 from over a decade ago. While my wife and I were decluttering the house, I stumbled across the R4 and decided to see if I could use it as a secondary backup solution. I installed a couple of spare drives I had, and managed to scrounge up a Thunderbolt 2 cable and adapter to use with my M4 Mac. Using the Promise KB articles, I was able to successfully update the firmware on my old Pegasus and was happy to find that it still worked just as well as it had when I bought it back in 2011. I was pleasantly surprised to find that the new Pegasus software is backwards compatible with legacy hardware, and even more happy that Promise maintains documentation for users with legacy hardware.
So glad that the old R4 will have a new life alongside my Pegasus32. Cheers to the Promise team for the excellent documentation and support - you have a loyal customer for life.
