Moving them over won't work because they're 64K chips and Bank 0 requires 256K as this is a 256K-640K board.
It's definitely not a VGA card, so even if you equipped a VGA monitor with an adapter, without driver software you still might not see anything, since there's nothing to drive the 7220 on the card.
The 7220 cards might be called second-generation high-resolution card. I suppose you'd call the first generation of hi-res graphics, the IBM PGC (or PGA) which used its own 8088 onboard and could emulate a CGA.
The next generation of specialized high-res display adapters were the TI 34010 graphics processor-based ones or "TIGA" cards. Most had a basic VGA controller on them to handle ordinary stuff, but again, special software for the likes of AutoCAD or CADVance or a host of other packages was necessary for full operation.

No, you only need Bank 0... but, as already stated above, it requires 256K chips, not 64K.ah, so I would need bank 0 as well as 1 to be filled in order to boot? so if thats the case i need at least 2 more of those ram chips.
Just about. In theory, if you have a Multisync monitor or equivalent and are willing to try every possible combination of switches on the card, you might hit on a setting that actually displays. Note that even with a Multisync display, it is possible to have a mode the display won't handle which could result in damage. Use caution.so basicly without identify the card and finding the correct drivers this card could basicly be useless and not display anything?

Not only the same thing but at the (exact) same time. I already know there's a wormhole between where I am and where MikeS is but that's only about five hundred miles. If there's also one between me and you -- that's over 8,000 miles!I hit submit just after Stone had posted, we're saying the same thing
Eerie... think I'll call in to Coast-to-Coast AM about it tonight...Not only the same thing but at the (exact) same time.
Hey, are you in the right thread?If you had a CAD application, it was not unusual to have two displays--one, usually an MDA for handling text-based operation with the basic operating software and another, a high-resolution graphics display for doing the actual CAD work.
It made sense--remember that this was pre-Windows and a 4.77MHz can be terribly slow, particularly when handling high-resolution graphics.
If he's not, then that means that everyone else who has posted a comment about the 7220 based video card is also in the wrong thread.Hey, are you in the right thread?
I saw one of those in action at a local expo/convention way back when. One of the first time I'd looked at a PC and I was blown away; imagine, one program driving two separate displays, and a crisp sharp graphics display at that!If you had a CAD application, it was not unusual to have two displays--one, usually an MDA for handling text-based operation with the basic operating software and another, a high-resolution graphics display for doing the actual CAD work.
The important thing is, of course, is to go back to the Goodwill and get the rest of the pile.

I've visited my (Illinois) goodwill weekly for a decade and never found anything decent. I don't know where you guys find these things
The electronics department usually consists of broken clock radios, hair dryers, curling irons, and overpriced audio and video components (who would pay $39.99 for a used DVD player with no remote, when you can buy a brand new one for $20?).
