We've been talking about doing a Retro Computing issue for yonks, but just wanted to make sure it was absolutely perfect.

To say we're excited by this edition of The MagPi is a huge understatement. Our massive 12-page feature has information on all of the following:

• Hardware emulation and classic coding
• The best emulators for Raspberry Pi
• Using a Retro Computer
• The best retro computer community builds

Wait, there's more! Learn how to put a Raspberry Pi inside a classic computer. Computer buff PJ Evans explains how he hooked up a Raspberry Pi inside a Sinclair Spectrum 48K. It even connects to the rubber keyboard to the GPIO pins on a Pi Zero W.

Super Pi Security, Watch Dog robots, and more!

And if that wasn't enough, we've also got a superb Pi Security feature this month. It covers every aspect of staying safe, and private, online. From setting up Tor and Pi Hole to picking secure passwords and locking down your computer.

That's on top of some of the finest community projects we've seen in a long while. There's a frankly intimidating Security Guard Watchdog built using Raspberry Pi, an amazing use of Pi to improve hearing aids, and an arcade machine in a lunchbox.

Oh! And you can learn how to build a Geiger Counter in this months magazine. It's a little random but lots of fun.

Don't miss this issue. It's a keeper.
