WDC VGA 16 (WD90C00-JK)

Postby derSammler » 2017-12-22 @ 10:25

Got this card together with a 286 mainboard from an old Peacock PC. Seems to be the same card as the Paradise PVGA1A-JK after WD bought them. Even the FCC ID is the same... Is that card any good? Would it provide enough speed for something faster than a 286?

Not sure if it would provide good performance in anything post-286,
but generally speaking, the PVGA1X and WD90CXX series are very compatible and have mode utilities even.

The last model, WD90C31, even had support for drawing GDI graphics primitives.
According to that site, it was one of the fastest ISA cards.

Another advantage is the good driver support for early software titles.
For example, Wonderland by Magnetic Scrolls (a game) supports its 800x600 mode (SVGA).
Same for early CAD software, Windows 2.x, GEM or Public Domain software (picture viewers, etc.)

This is a SLOW Card, in a Class with OAK VGA and Trident 8900

Very combatible with older Video Modes, but not fast at all :)

The Later WDC Chips mentioned above are the fastest 320x200 Performers Made for ISA.

A Card using it is the Diamond Speedstar 24X.

Tested the card today and yes, it's quite damn slow. Have to check if the other two ISA VGA cards I have are faster.

What program is that? I have lots of cards to test and I like benchmarks with copious amounts of data. :lol:

I still have a CL5420, which did 4.6 MB/s when tested yesterday. But I have to reflow the video chip due to bad solder joints.

I ran some tests with Dr Hard 3.5e on my 386 DX 25 system. Thought you might be interested in the results. All cards are ISA.

First up is a 512K Western Digital Paradise WDC90C30

As you can see this is a very fast card for DOS, it only goes downhill from here!
Next is a 1MB OAK OTI-077

Next is a 1MB Trident 8900B jumpered for 16-bit operation.

finally a 512K Realtek RTG3105iEH, 120ns RAM on this card plus they only operate in 8-bit mode despite being a 16-bit card.

Anyone got anything slower than that Realtek?

Thanks. Got a WDC90C30 today, so I know now what to expect when I use it. :D

Congratulations! :) Some cards with that chip were also named PVGA1D, by the way. Probably as an allusion to the ancestor PVGA1/PVGA1A (later named WD90C00)..
