Man, thats so long......
Yes I remember reading the articles back in 92/93, and yes there was an Amiga version.
It probraly needed a special set of GALs, which seem to be out of stock....
I also remember it only having 256 or 512k of static RAM, just enough to put the Kickstart into, so you shouldn't expect a performance boost anything close to what a 030 with RAM would give. Even a lousy 020 will outperform you.
Maybe try this (targeted at A1000-Phönix)
