It's been a little while since I did proto boards, but I remember a vast chasm between industrial & hobbyist, that basically forced me to wrangle packages I had no desire to deal with. You could get 4GB DDR2 DIMMs, or you could get a DIP 8kB SRAM. For a microchip you could get TQFP-32, or BGA-1000. So on and so forth. I remember a useful chip that came in nothing but QFN-16.

It seemed like it wasn't I need fancy gear to make blinky lights, but rather for anything better than 8-bit, kilobyte, and low MHz, the only parts available was the fancy commercial stuff.
