- The oMniBus board I mentioned before does essentially this, now. This board
- is a bus translation Bridge Card, probably designed just to handle Zorro II to
- VGA translations (I gather GoldenGate does arbitrary ISA to Zorro II bus
- translations). The board also has what amounts to a software controller A/B
- switch box, which can gate through either Amiga or VGA card video to your
- monitor. The software provided does a pretty good job of providing several
- new monitor types that run on the VGA card. You can have Workbench, public
- screens, or most anything that uses the monitor type file requester running
- on the VGA card. Obviously, RTG would make this more efficient and more
- compatible, but it's run most of what I've thrown at it so far (one reason it
- works as well as it does is that it will switch in real Amiga video when that
- kind of monitor type is requested -- some kind of promotion/coersion of
- monitor types on alternate displays like this would be really tough to get
- right).
