No. The RISC systems were 100% 64 bit, SPD or not.

When IBM first advertised RISC on the AS/400, it was a case of "64 bits, no buts...". That implied 64-bit all the way through! Now, was the old SPD technology on the CISC machines 48 or 64 bit? Why do we have 'low speed' and 'high speed' slots on the older RISC machines? In my mind, the SPD technology is 48 bit, with the low speed slots on the RISC systems there to accommodate 48-bit within the RISC environment. Am I wrong in my assumptions? Please enlighten. I know that this probably has no bearing on the new equipment; it is just that the recent discussion regarding the 'new' 64-bit OS's that are due have brought this to mind again. Thanks.
