I just need a *****!

there are several stores in the area selling hardware in a pinch. unfortunately, none of them are really within walking distance of the space. if you need something quick for a project, here are some ideas for where to go:

RE-PC

two locations: a closer one by stadium station (south of downtown, take the 1 line south towards angle lake), and a further one in tukwila (by southcenter mall)
sells used tech and surplus, lots of specialized and consumer items, including a fair amount of retro hardware
probably has the cable you need
you can call them to ask them if they have something, seattle location (206) 623-9151 or tukwila location (206) 575-8737

Fred Meyer

has a surprisingly large selection of consumer electronics and knockoffs
standard or slightly over retail prices, sometimes for sub-retail-quality products
closest location by bus is greenwood, 45 bus goes door-to-door, take towards loyal heights and get off at 85th and 3rd
aggressive security guards, be ready to show your receipt

Best Buy

sells most general consumer tech items
in the northgate north shopping center, north of northeast northgate way and west of 5th ave NE
all new, overpriced monopolism bs
near northgate station (take the 1 line north towards lynwood) then walk, or take the 75 for a direct but slow ride

Target

same complex as best buy
in the northgate north shopping center, north of northeast northgate way and west of 5th ave NE
sells cheaper shit then best buy but some of it might not work
less selection than best buy
near northgate station (take the 1 line north towards lynwood) then walk, or take the 75 for a direct but slow ride

Guitar Center

tied for closest store on this list, technically within walking distance if you're fast
only hardware sold is audio/MIDI gear
sometimes has some good used deals, but required to keep used items for a while before selling them
near roosevelt station (take the 1 line north towards lynwood)

Goodwill

central district location is the big one
sells a lot of keyboards, dvd players, other used consumer hardware
take the one line south towards angle lake, then transfer at international district/chinatown station to the 7 towards rainier beach, get off at rainier and king

UW Surplus

tied for closest store on this list, technically within walking distance if you're fast
only open for a few hours on tuesdays
computer items tend to be sold in bulk online, but a few deals here and there to be found in person
across the street from the u villiage shopping mall
take the 31 or 32 bus towards seattle children's hospital
