One thing that hasn't been quite ultimate enough with regard to my Ultimate Ultima 7 machine is the VGA card. In my humble opinion the Tseng ET4000AX chipset is the best looking VGA chipset by a mile (pre-Matrox Millennium), but sadly the motherboard I'm using here - the OPTi 495SLC - seems to have an incompatibility with the VLB version of the ET4000AX (it has no problem with the ISA version, but I can't bring myself to use an ISA card in a VLB motherboard). Determined to beat that issue I've tracked down an original paper copy of the manual for the 495SLC motherboard, which documented the various jumper and BIOS settings for the board far more comprehensively than stason. I was able to improve overall performance a small amount perhaps, but the incompatibility remained. After a year and a half of searching, I also managed to track down a second VLB card which uses the ET4000AX chipset - this is actually an ISA chipset originally, so VLB cards generally have the ET4000/W32 chipset and up. Unfortunately the new card had the exactly same problem, Ultima 7 (and some other games) are displayed with evenly spaced black bars running vertically down the screen every 1cm or so.
So I've given up on the Tseng dream for this machine (note that I have tried a ET4000/W32 based VLB card and wasn't impressed), but before settling for a Cirrus Logic GD5428 - which I've been using since putting this PC together - I decided to spend some time trying out the other VLB VGA cards I've stashed away over the years to see if I could top it. My requirements for this card are:
- As close to the bright, colourful and sharp image provided by the ET4000AX as possible. I've graded each card with A (best) to C (worst) on "Brightness/Colour" and "Sharpness" to help determine which one is best in this regard.
- All VLB cards I've tried with Ultima 7 exhibit a "shimmering pixel" effect to some degree, where a thin, horizontal line of pixels "shimmer" for the width of the screen and cause the mouse cursor to flash when in contact with said pixels. Some cards do it more than others, most aren't even noticeable, but on some cards it's right in the middle of the screen so it can get annoying. My ultimate card would have minimal shimmering.
- Compatible. I'd like to play games on this machine other than Ultima 7, so Keen 4 and Jazz Jackrabbit - which I've experienced compatibility issues with in the past - were used as a simple test of a card's DOS game compatibility. As it turns out all cards below worked fine with these games.
Nice-to-haves are speed and memory expandability. This is a DOS only machine and it won't be used for graphically demanding games.
Obviously this isn't a scientific test in any way - just subjective ramblings for my own amusement really - but I thought someone with an interest in VLB cards might like to see what I decided on. Here are the results:
S3 805.
I got this from Germany at some stage, and indeed it's "German designed". S3's are supposed to be very compatible and it was the second fastest card I have. Overall it’s a decent card.

Very slight shimmer
Brightness/Colour: B
Sharpness: A+
Memory expandable?
No
WDC Paradise WD90C33.
I picked this up locally for a few bucks a while back and it's a very interesting card. It's from '94 so quite late in the VLB timeframe and it has numerous jumpers and switches to change the font and set refresh rates at different resolutions.

Very slight shimmer

Yes
ATi Mach 64.
This thing uses a strange font and is otherwise unremarkable.

Ultima 7
Noticeable shimmering
Brightness/Colour: B-
Sharpness: A
Memory expandable?
Yes, proprietary module required though.
Trident TGUI9440A.
I forgot to run 3DBench on this thing - I was so disgusted with the image quality that I wanted it out of my sight ASAP.
Ultima 7
Noticeable shimmer
Brightness/Colour: C-
Sharpness: B
Memory expandable?
Yes
ARK Logic 1000VL.
ARK cards are supposed to be very fast in DOS and this one is just that, otherwise it has nothing going for it however.

Noticeable shimmer

Yes
Cirrus Logic GD5428.
I have several Cirrus Logic cards and they’re consistently very good, but not quite great because of image quality. Actually one of them produces a great image – very bright and sharp – but it also produces terrible moire on my beloved Sony CRT, so I can’t use it.

The S3, Cirrus Logic and Paradise cards were all pretty much even-stevens, but in the end I decided to go with the WDC Paradise card. It produces a really beautiful image (not quite up to the ET4000AX standard but close), can have its memory expanded if need be, and has a number of interesting jumpers / switches to play around with which is always a bonus. I also like that I have the documentation for this card, found here:
http://museum.ttrk.ee/th99/v/U-Z/50034.htm
It was actually the slowest card apart from the Trident which I didn’t run 3DBench on, but I assume would be slower. As I said speed isn’t really an issue, I’m more interested in pretty pictures for this pre-DOOM machine. So I’ll Journey Onward with this card for now and hope for the best.
Life? Don't talk to me about life.
