I guess so. I think XSurf was the last ones ever made.
I never got to use it though 
When I first bought the card, we were still using dialup in Turkey and the card was faulty anyway (my box was opened by someone at the customs and I saw the card on the floor
). I never managed to fix or send the card for replacement since my 4000T stopped working.
So even in 2003, I was still using dialup on my A4000T. (and then the P8 connector from the PSU wielded itself to the p8 connector of the 4000T and I am still waiting for someone to repair it. Hopefully it will be repaired in one month (I have bought a shotgun and going to meet the person who is going to fix the mainboard in a month)
Oh man.. A4000T on dial up brings back memories for me. This was before 2003

. And I was sniping ebay auctions using dial-up. So much fun, thrilling counting down in my head to time my confirm bid, adding 10secs for the actual bid to register ha. To me it was exciting. I got pretty good at it.. I was sniping auctions before anyone even called it "sniping" lol.
Dang if you only lived closer could fix that in a jiff(that means fast

... ) Ouch careful what you type hehe..
