An interactive Vintage Computing Encyclopedia Explore the golden age of home computing with detailed profiles of over 100 vintage computers - from the Altair 8800 and Apple I to the Amiga, ZX Spectrum, and beyond. Whether you grew up typing BASIC programs on a Saturday morning or you're discovering these machines for the first time, Retro Computers is the ultimate pocket reference for the golden home computer era. BROWSE OVER 100 CLASSIC COMPUTERS Each entry includes the full story: release year, manufacturer, CPU, RAM, display, original price (with inflation-adjusted 2026 values), units sold, and more. Illustrated with photos of the hardware, circuit boards, keyboards, and character sets. This app covers machines from Britain, America, Japan, and Europe: Sinclair, Acorn, Amstrad, Commodore, Apple, Atari, Tandy, Sharp, NEC, and many more. If it had a keyboard and ran BASIC, it's probably in here. 17 IN-DEPTH TOPIC ARTICLES Deep dives into the technology and culture that defined an era: • The CPU Wars - Z80 vs 6502 vs 68000 • The Evolution of Graphics and Sound • BASIC: Every Computer Had It, No Two Were the Same • Floppy Disks, Cassettes, and Microdrives • Modems, BBSes, and the Proto-Internet • Computer Magazines, Repair & Restoration, and more. COLLECTORS CATALOG Keep track of which computers are in your own collection, and which you really like. Export your collection at any time. INTERACTIVE TIMELINE See every computer plotted on a scrollable, zoomable timeline. Pinch to zoom and tap any machine to learn more. COMPUTER DUEL Play a card game where vintage computers battle it out on specs. Can the ZX Spectrum beat the Commodore 64 on clock speed? There's only one way to find out. QUIZ MODE Test your retro computing knowledge with 10 randomized trivia questions. Identify computers from photos, guess release years, match manufacturers, and compare specs. COMPARE SIDE BY SIDE Put any two computers next to each other and compare their specs, prices, and capabilities. ON THIS DAY Discover which vintage computers share a connection to today's date (includes a widget for your iPhone or iPad screen!) DESIGN YOUR OWN COMPUTER As the owner of your own computer company in 1984, will your design be a hit? BUILT FOR READABILITY Large, legible text designed for comfortable reading. SHARE your passion. Many views allow you to share images to your favorite social media channels. EXPERIENCE a growing number of computers as 3D models you can view in AR.

No internet connection required for most features (but links to many current sources for further information are provided, and emulators require access). No ads. No tracking. No in-app purchases to unlock functionality. It's good old retro shareware! Enjoy it? Then tip your developer to encourage updates.

Carry the world's largest encyclopedia in your pocket — and read it anywhere, even miles from the nearest signal. Lirum Wiki turns your iPhone, iPad, and Mac into a complete, self-contained library. Import Wikipedia and OpenZIM archives from Files, iCloud Drive, network shares, or external drives, or download them straight from the built-in Kiwix catalog. Once stored, everything works offline: reading, search, bookmarks, PDF export, and even a private AI conversation about the article in front of you. WHY YOU'LL LOVE IT • Truly offline — read, search, and study on a plane, on a trail, off the grid • One gorgeous native app designed for iPhone, iPad, and Mac • Fast title and full-text search with instant snippets • Private, on-device AI chat about any article • Five handcrafted reading themes, each with light and dark appearance • No account, no ads, no analytics, no telemetry — your library stays yours BUILD YOUR LIBRARY YOUR WAY • Open full OpenZIM archives directly, with no conversion or extraction • Import from Files, iCloud Drive, SMB and NAS shares, or external storage • Browse the multilingual Kiwix catalog and download new archives in-app • Queue entire batches of archives at once and manage them as one • Pause and safely resume even the largest transfers • Open archives in place and read huge collections without copying them first • See each archive's language, date, article count, and media details at a glance • Reclaim space confidently with per-archive storage details and confirmed deletion • Export archives back out to Files, NAS, or external storage A READER THAT FEELS LIKE HOME • Five themes from classic encyclopedia to modern magazine editorial • Adjustable text size for comfortable reading • Find within an article and jump straight to highlighted, clickable excerpts • Random-article and archive-home shortcuts for a little serendipity • Copy, share, or export any article as a PDF • Organize bookmarks in folders with portable backup and restore PRIVATE ON-DEVICE ARTICLE CHAT Ask for a summary, the key facts, a simpler explanation, or a study guide. Answers are grounded in the very article on your screen, including its sections and infobox. On supported devices, choose Apple Foundation Models or a curated library of validated local models — Gemma, Llama, and more — including multimodal models that can discuss an attached image or voice note. Your questions, answers, and article text never leave the device. ONE APP, EVERY SCREEN Lirum Wiki is a native SwiftUI app, not a web wrapper. Reader tools fold into elegant sidebars on iPad and Mac, search stays within reach in any orientation, and your library, bookmarks, and themes feel at home on every device you own. A note on big downloads: transfers on iPhone and iPad run in the foreground, and Lirum Wiki preserves resumable progress if the app is interrupted. Lirum Wiki is an independent OpenZIM reader and is not affiliated with the Wikimedia Foundation or Kiwix. Wikipedia and related marks belong to the Wikimedia Foundation.
