My first computer was the Radio Shack TRS80 (Trash80) that I had a text based dungeon crawler. Then I stepped up to the big leagues with ColecoVision with the 2600 extension. Then came the NES with some Zelda and Super Techmo. Followed quickly by my Sega Genesis. But what really got me were Doom, Rise of the Triad and Quake. I still have all the systems, and yes they are connected to an old monitor on an A/B switch. good times.
