- It is a single chip video engine from Tseng Labs. The ET4000 actually shows
- up more than you think, since the Orchid Prodesigner II is also an
- ET4000 board. My ET4000 reference is at home, but it will run in CGA, EGA,
- Hercules, AT&T (640x400), VGA and super-VGA modes. The speed comes from
- the combination of a lot of internal caches and it's ability to address
- video memory as 32-bit words.

- A block diagram would look like:
-
- CPU <-> buss <-> ET4000 <-> 32bit display memory
- \
- \--> monitor
