In 1985, Commodore followed up on its best selling Commodore 64 with a model with twice as much memory. The design of the 128 offered the possibility of following up with a Commodore 256. It never happened. Instead, Commodore moved

Over the course of its 12 years on the market, Commodore released a number of Commodore 64 models. The computer’s capability changed very little over time, but the technology did. The world changed a lot between 1982 and 1994, and

The Atari 2600 CPU: The MOS 6507

Dave Farquhar — Mon, 29 May 2017 11:00:40 +0000

The Atari 2600 CPU was a nondescript MOS 6507 chip. Neither Intel nor Motorola had a CPU chip in the early 1970s that could meet Atari’s price point. MOS Technology didn’t have one either, but they asked Atari what they

Commodore 64 vs Amiga

Dave Farquhar — Fri, 03 Mar 2017 12:00:14 +0000

Looking at the Commodore 64 vs Amiga seems a little odd, at least to me. After all, the machines were never intended to be rivals. The Amiga was supposed to succeed the 64. Commodore bought Amiga because they couldn’t make a

Purists prefer CRT monitors for a more authentic experience, but if you don’t mind an LCD, here’s a good LCD monitor for retro computing. Look for a Dell 2001fp manufactured in June 2005 or before. For bonus points, try to
