Bought this VLB caching IDE controller, going to get it in about 3 days. Here's the seller's photo:

I've been able to identify it as a Hornet Technology VL-200 thanks to this 14-year old post on a German message board. Here's a full photo:

Now, this looks like a bit of a different version — it has an Appian IDE chip (mine has what looks like Adaptec AIC-25VL01Q.
In the original post they say this controller had a "fake" CPU under a square white sticker and the Appian chip is a common VLB IDE solution that doesn't use caching. They also quote an article from C't magazine 3'94 that tested this controller and found no performance improvement. They went as long as to say that this was a "warmplate" for memory sticks.
On the other hand, they mention that this controller was actually more expensive than cached IDE controllers from Tekram and Promise. So I'm guessing maybe the performance issue was an oversight rather than PC Chips "fake cache" situation. Besides, I see that someone must have deliberately upgraded the RAM (two sets of different sticks), so it must have done something.
While I'm waiting for the controller I wanted to ask if anyone has a manual or drivers for this card. Or maybe someone knows the original website URL for Hornet Technology? Right now Hornet seems to be a Grindr-like app, so it's pretty hard to google for any info.
