Memory was expensive( I still have a IBM PC-1 with the 16K drams running in it (along with 64K's and 256K's ...what a technology mix ;-) ) and certainly was a consideration. By going to x-8 instead of x-16 a memory upgrade was cheaper, and anything receiving the bus was cheaper to implement. Also don't forget that the whole world was still 8 bit oriented due to the proliferation of 8 bit S100 systems using Z80's and such. The user community didn't expect 16 bits yet. Steve Wilson The above are my opinions only, not those of my employer.
