Everyone talks about the 808 to death, but his greatest contribution was the MIDI spec.
someone would have come up with a "standard" at some point, yamaha went off with their own version with XG as did roland.. but the TR / JV machines etc . inc. the 808 is important. it's talked about a LOT because of the impact it had... much as guitar stuff hasn't impacted me doing electronic music. try making a house tune without a 808+909, thats just one example.
in the 90's a juno 106 / jd800 / jv1080 was standard issue in the majority of studios I went. jupiter 8 was in a few places, but they were far from cheap to buy.
take roland stuff out of a 90's+ studio (or even the vst clones) then many a tune become a LOT lighter
