ET1000 "UltraPak"
MDA,CGA and Hercules compatible. 132-column text modes. For monochrome monitors only.
"ColorPak"
CGA compatible. Adds proprietary 400 line modes and up to 8 on screen colours.
ET3000AX/BX
Basic VGA chipset
ET4000AX
Usually available with 512kb or 1mb DRAM. Very fast frame buffer. ISA and VLB interface.
ET4000W32
Similar to ET4000AX, but with 32-bit windows graphics acceleration.
ET4000W32i
Similar to ET4000W32, but with support for interleaved DRAM when configured with 2MB. DRAM interleaving provided roughly 85% of the throughput of a true 64-bit interface.
ET4000W32p
Similar to ET4000W32i, but with support for PCI.
ET6000
64-bit graphics accelleration with 2.25 or 4.0MB of MDRAM. Integrates RAMDAC into the graphics core.
ET6100
Improves the integrated RAMDAC to address problems with blurriness at higher resolutions. Uses faster MDRAM.
ET6300
Unknown. No cards based on this chip are known to exist, so it may have been a paper release only. It is also possible it saw limited release in Asia. Likely adds video acceleration.
