Someone calling himself "DeadDrPhibes" has a great post up at The Older Gamers Paradise called The Birth of PC Gaming. The author takes us on a little tour of the earliest days of home PCs and gaming, starting with furniture-sized monstrosities and ending up with the Apple Mac and the Windows PC. He strikes me as a died-in-the-wall TRS-80 man, and spends good time discussing Radio Shack and Texas Instruments' entries in the home computing market (the CoCo, and so on). It's a fun read, even if it seems to be drafted mostly from the author's own experiences and memories. At any rate, it's nice to see a history like this from this perspective, since most "history-lite" like this I've read has focused mostly on the Apple, Commodore, or IBM. Now all I'm waiting for is a great feature on the Atari line of home computers.
