First of all, I’d like to thank those who chimed in, namely BDAqua, Jeff, Glen Doggett, as well as Allan Jones.
After consuming all of this, and checking out the references, I think I can better help you help me by explaining exactly what I’m trying to accomplish.
Maybe to my good, I am not needing high-end graphics. There are two types of document displays I’m working with. One is a MIDI sequencer with it’s typical windows, and the other is AppleWorks 5 WP docs (charts I’ve made). Up until now, I’ve been using my Macintosh PB1400C laptops for in-studio as well as performing. Believe me, for what I’m doing, they’ve been, and still are, great. So, it would seem to me that anything even “low-end” on the Beige G3 Tower w/LCD flat-screens would at least equal what I’ve been experiencing. It’s just that I want to use the G3 and dual LCD monitors (probably 19”) to gain real estate in the studio.
As to BDAqua’s comments, it appears I was misled by an online article claiming that VGA would not support above 1280 x 1024, so that may be good. The reason is that I had already purchased two VGA PCI cards that are in the machine. They are identical, and are Apple 630-2858, ATI 109-57400-00 Rage 16MB PCI. They were used cards with no CD or documentation, but yet they work fine. it’s just that I couldn’t get 1600 x 1200 res, but then I realized my “test” monitors (thrift store) wouldn’t support above 1280 x 1024, so THAT may be the reason.
I need to mention one other thing here. Aside from the resolution, I experienced that plugging one monitor into the factory monitor out on the G3 w/ a VGA adpt., and the other to either one of the cards, both monitors worked, and I could drag docs from one to the other . . . just what I wanted. But when I attached the two monitors to the two VGA cards, the machine would stall on start up, after 3 - 4 icons appeared, and never boot. I tried this back & forth several times . . . always the same results both ways.
So one question now would be why would that be happening since both cards work one at a time? I can always use the factory port and one card if I have to.
The other question is . . . now that I’ve discovered that VGA will indeed support the 1600 x 1200 res I’m after, will the cards I mentioned above that I already have, achieve this, as long as I have monitors that have 1600 x 1200 as their native res?
And finally . . . don’t forget . . . in regards to your suggestions on video cards, I’m using, and have to stay with, OS 8.5.1. Most of your references have to do with OS 9 and X.
Maybe with this extra info, I’ll be able to get to (or very close to) a solution. And again . . . a BIG thank you to ALL who have attempted to help so far.
