  The very first Archimedes were the A3xx which used the ARM 2 chip. 
However, that was socketed, so you could easily upgrade it to an ARM3 
by just buying it and plugging it in. The ARM3 also had hardware 
support for floating point. So your A400 must have either an ARM2 or 
an ARM3 (it cannot support any other processor). You probably have an 
ARM2, so it would be worthwhile upgrading because the ARM3 is about 
4-5 times faster..!  : -)
