Sure Dave, it's the latest version of the 68030 blizzard cards. Most people will tell you its the one to buy as cost, vs performance and reliability it offers good value and stability.
It's compatible with whdload games and makes using workbench a much faster experience.
You can add a scsi board to the blizzard which also gives you capacity to upgrade the ram to 256 mb
I'm selling as I have the opportunity to buy an aca1230 56mhz, these are a little faster bit can be unstable. I'm looking for a little more speed from the 3D stuff but to be honest it's marginal, the blizzard is no slouch.
The blizzard is in perfect condition, I'll take some pics later.
