I think the Apollo 1220 had a full '020 instead of an EC '020 so it might speed thing up a little bit. Really the main reason for buying an accelerator card for an A1200 is not the speed so much as the memory addressing. 8 Megs of fast doesn't go very far but 32-64 megs does.
At one time I had 32 megs in my Blizzard 1230 (50MHz w/ FPU) with SCSI kit and was able to run ADoom without accessing the stinkin' hard drive all of the time by renaming the WAD file and creating a soft link to the RAM disk and copying the WAD file to the RAM disk every time I wanted to play. That speeded things up just enough to make them playable.
Memory is the issue more than speed.
