DIP Switches:
1--2--3--4
on-off-off-on = 40x25 Color monitor
off-off-off-on = 80x25 Color monitor
on-on-on-off = Enhanced Color Display, CGA emulation
off-on-on-off = Enhanced Color Display, Hi-Res
on-off-on-off = Mono Monitor + CGA 40x25
off-off-on-off = Mono Monitor + CGA 80x25

5 --6 is LPT on/off and address selector (3BCh/378h)

JP1
1-2 EGA monitor
2-3 CGA/Monochrome monitor

JP2
ISA pin A1 - I/O channel check report

Notes: The ROM type specified on a silkscreen is 27128, but the card had 27256 and the bios image was duplicated in upper half of the chip.

I'd like to offer an update to #14 since I have one (it seems to be called "PA-WTEGA").
The BIOS dump matches mine and I read the EPROM using external programmer. There's a project that re-created the PCB (and full schematic) so anyone can build it provided they have the chips, and the DIPs have been figured out:

The card has a bank of 5 dipswitches.

Dipswitch 1-4 select the card video output mode:
0-1-0-0: MDA Mode (main)
1-0-0-1: CGA 40x25 (main)
1-0-0-0: CGA 80x25 (main)
0-1-1-1: EGA 200 lines (main)
0-1-1-0: EGA 350 lines (main)
1-1-1-1: CGA 40x25 (secondary)
1-1-1-0: CGA 80x25 (secondary)
1-1-0-1: EGA 200 lines (secondary)
1-1-0-0: EGA 350 lines (secondary)

Dipswitch 5 selects the IO address:
0: I/O address range in 3xx (default)
1: I/O address range in 2xx

0 means switch open, 1 means closed.

I don't have EGA/CGA monitor to test it, only a mono MDA/Hercules one that does accept 60Hz CGA input and shows colors as different intensity. I tried MDA emulation and CGA modes, it all seems to work properly with my monitor.
