- I don't think you know what you are talking about. The fat/fatter agnus
- also replaces the multiplexing logics, generate system clocks and
- require extra address lines to access the extra ram. Basically, you'll
- have to put a 48 plug to the existing agnus socket, a few wires to the
- 68000 socket, hack the kickstart daughter board and some how synchronize
- the clock generation circuits inside that shield box. If it were just
- a MegAchip type of setup, I'll bet thousands of 1000 people would have
- done it. In comparison, MegAchip is plug & go.
