The viper sysinfo report : 7489 dhrystones 7.81 mips(@40Mhz)
The ACA630 sysinfo report : 5712 dhrystones 5.96 mips
From this report it seems that the Viper is fastest than the ACA630.
40MHz is more than 30MHz. However, you're quoting the Sysinfo values of the 25MHz card. The 30MHz card is faster: Sysinfo reports 7.24 MIPS and 6936 Dhrystones. The extremely fast memory transfer gives it incredible integer power. In practise, you will hardly tell a difference between your 40MHz card and the ACA630-30. If you want to compare the ACA630-30's power to your own system, please download the AIBB module that I have uploaded yesterday.

It's impossible with the Viper 630. How it can be possible ?
Memory access speed. Try "bustest" from Aminet and compare to the values that we've posted in this thread. A processor can only be as fast as it's memory. If memory is slow, then all the MHz in the world won't help you: The CPU is idle, waiting for the next instruction.

This special "port" takes advantage of Indivision ECS features. However, we're also testing with the standard version from Aminet: It makes 7 frames per second. What's the speed that your Viper makes?

A 68030 is too slow to play MP3. Have a look at Delfina or the MAS player if you want to play MP3 with your A600.

ACA1230 and ACA630 are all PCMCIA-friendly.

Don't compare the 630 price to the 1230 price - they are completely differnt designs, different mechanical solution, even different bus timing as one is a sync and the other is an async design. It is not correct to speak of "raising" the price over the 99,- EUR for the A1200 28MHz card. It's like comparing the price of a bicycle and a motorcycle - they are different things.

Once again, if you want to judge it's speed and compare it to your system, then the AIBB module that I have uploaded yesterday is the best way to do so.

I'll leave it up to the first customers to make those videos. It's a lot of work to do such a video right, and there's legal issues as well, especially if we're showing ADoom, which may not be shown in Germany (game was rated too violent). We're even avoiding to mention the name on the German forums.
