I highly recommend Jimmy Maher's Digital Antiquarian blog at http://www.filfre.net/ http://www.filfre.net/ The focus is mainly on computer games from the late 70s (and currently up to the late 80s), but that includes general posts about personal computers like the Apple ][, TRS-80, Commodore 64 and Amiga and the personalities behind them, on programming languages like Forth and the various tricks and inventions required to get complex games to run on very restrained hardware. It's all very readable, meticulously researched and quite in-depth.
