Well .. in my A3000 I have a WarpEngine 040 @40mhz.
I haven't had one bit of trouble with it and it has
a very fast SCSI and 64 megs 72 pin simms.
(IMHO .. a very good reliable card)
In my A2000 I have a GVP TekMagic 060 @ 50mhz.
The only problem I've had with it is with OS 3.9
and the 'WarmBoot problem' that so many people have
with OS 3.9. So I can't really fault the GVP card for
that. It has a good SCSI and 128 megs 72 pin simms.
(also IMHO .. a very good reliable card)
With all the talk about the CSPPC cards and the
Blizzard, there always seems to be a thread on A.org
asking where to get them repaired.
I personally don't think I want one.
