Works like a charm! 512 in it. The other card I have is the diamond flower vg-6000. I'll give the two a comparison when I can. Glad to know the VGA wonder series are good cards. I'm new to this forum and appreciate all the help. I had always been interested in infocoms interactive fiction so set up a 5150 with 5151 for that.... but of course that became the beginning. Then the 5160, currently with 5154 and now the 5170 with a sony vga, may end up moving the 5154 to the 5170 anyway. Was there a VGA that was favored around the era of 5170? Or was the EGA the best match at the time? thanks to everyone for the great first puzzle solved using the forum.
