OK, from my colection, I could justify the historical impact of the 
following : 

HP9100 (alas mine's a B), one of the first programmable desktop machines
One of the PDP11s (probably the 11/45), for obvious reasons
PET2001 / TRS-80 Model 1 / Apple ][ (First mass-marketted micros)
Sinclar ZX81 (Instroduced a lot of UK kids to computing)
C64 (Ditto, in the States)
IBM PC 5150 (Surely you don't need me to explain why :-))
