What 'modern technology'? Jets? Rockets!?
There is no 'modern technology' as what you see on a current bike is just an evolution of existing products
What has changed is how things attach to other things which makes them often completely incompatible with older frames although some thoughtful souls came along with adaptors
Any Shimano compatible 8spd hub can use a 10spd cassette so that goes right back to wheelsets from 1992, that gives you access to 10spd drive trains
V-brakes or Magura hydraulic rim brakes - unless you find disc brake adaptors for the rear and new forks for the front but as v-brakes are pretty decent, try them first
Newer forks would be better too as those Manitou are ok but that Marin rear suspension action was always far better than the front until better forks came along
The orange coloured swing arm belooooow had disc tabs welded to it by RB member danson67.
