Hullo. Could somebody give me a quick rundown of the differences in capabilities between GPX and SPX graphics on a VAXstation 3100, and how I might tell which I've actually got? According to the emblem on the front of the machine, I have an SPX-equipped unit. As I understand it this is what passes for 'top-of-the-line' graphics on the 3100. After the initial mix-up when I received the machine without any add-on graphics card, I was sent what was supposed to be the proper SPX card for the unit. Just the other day I happened to notice that 'show version' or some similar 'show' command in UCX indicated I had a 3100 with GPX graphics. Now I'm no longer sure what's what. Could somebody set me straight? ok r.
