I know this is a longshot, but I'm looking for the settings of all five
DIP switches on a Paradise VGA card from 1990. It has two strings on
the board, either of which could be the make/model:
PWBA 4316 0134-000
or
PW800 VGA
I'm assuming it's a paradise card, because the actual chip on it is from
Western Digital Corp. (a WD90C11-LR) and Paradise used them nearly
exclusively.
The reason I'm asking is because I'm looking for an 8-bit ISA VGA card,
and while this card is 16-bit, some of them could be DIP-switched to run
in an 8-bit slot.
There are five DIP switches on the backplate. No, I am not going to
plug it into my 5160 and power cycle it 32 times to go hunting for
something that works :)

Jim, I've got the docs (and probably the card somewhere) to the
Paradise VGA Plus, which was an 8-bit VGA card from 1988. There are
4 switches on the back defined thus:
SW1 - ON = Special multi-frequency display timing
OFF = Standard PS/2 compatible fixed frequency timing
SW2 - ON = PS/2 only; all VGA modes available on any monitor
OFF = PC/AT style; color modes on color monitors; mono
modes on mono monitors.
SW3, SW4 = not used, should be set OFF.
Hope this helps.
Cheers,
Chuck

My thanks to the both of you, except that my card has five switches, not
four :-(
Still, it's encouraging that the 16-bit info Teo posted mentioned an
"autosense 8/16-bit" switch, which leads me to believe that, if I ever
come across an 8-bit ISA machine I don't care about :-) I could use it
to test the card in all 32 iterations of it's switch bank.

This has 5 switches. next time try taking a picture, makes things so much
easier.

Jim, how about this one:
http://artofhacking.com/th99/v/U-Z/50102.htm
Does it look familiar? The WD90C11 was used on other cards,
including some no-name Taiwanese ones...

Here's another 5-DIPswitcher no-name:

Although the memory configuration is different, that's pretty much it!
I didn't realize I could search Total Hardware for things other than
model numbers... next time I'll be a little smarter. Thanks!
Sadly, it means I can't use this one. And on further inspection, many
of the 16-bit-part-of-the-card's contacts lead to a Motorola LS245, and
from there, to RAM, so I guess this one goes in the 286
pile.

You've probably already checked TH99, but if not here's a url:
<http://www.lemmus.eu/th99/index.html>
All the WD or Paradise cards I saw there with five-position switches
had the WD90C31 and used the switch bank to configure refresh rates,
wheras the ones with four-position switches all had the WD PVGA1A and
included a setting to force 8-bit autosense. I didn't see any WD or
Paradise cards with the WD90C11.
