Well, I THOUGHT I was running 4.7 on my home system. Seems
that was the last version that didn't require a license.
But, maybe I was NOT running 4.7, but some earlier version.
But, I would have had 4.7, not 4.7A, so maybe you needed the
4.7A to support the KA650.
I dug out some of my notes from the system, and it seems I
had VMS 4.7 and VMS 5.5 (which I couldn't run fully as I had
no license.) But, my memory of all this is a bit rusty,
now. I did have the system running continuously until 2007,
but didn't use it much online. It ran an environmental
monitoring program in the house, and displayed time, date
temp and humidity on a couple LCD displays. In 2007 I moved
that program over to a Linux PC, and the VAX hard drive
crashed a few weeks later.
