A co-worker recently gave me some old PC and monitors.
When I fired up the PC that she gave me, it worked perfectly - but loaded with Windows 95!
Loaded up the XL Timbuk2 bag with the CPU and had to close it with a ratchet strap, since the strap buckles couldn't reach with the PC inside.
So off to the Goodwill trailer at Kroger.
That thing was old-timey PC heavy. I could feel a difference in the Schwinn's steering, the tires, and especially on my back. Fortunately, it was not a real long trip.
