The 6502 development studio, emulator, teacher, and games machine you can bring with you; and a useful set of 6502 instructions for your Apple Watch too. The 6502 microprocessor changed the world. Released in the 1970’s, it was the reason that home computers were within the reach of many hobbyists. This app re-creates the 6502 CPU and some of the hardware that used it. This isn't a game (although games are included), this is an emulation of the 8-bit processor, complete with an assembler and some programming puzzles to solve. Start with the most basic user interface you can imagine - six 7-segment LEDs and some buttons - to enter, debug and run your applications. Then upgrade to a display and keyboard, and use the built-in monitor program to dump memory, makes edits and execute your code. Can you run BASIC? Maybe. FORTH? Perhaps. Assembler? Definitely! Don't think of this as a something "fun" or "enjoyable" in the traditional sense. Think of it as a puzzle: how on earth did those folks in the 1970's manage to do ANYTHING when computers were this basic? Documentation is provided, but to get the most of out of this app you'll need to do your own research. Just like in the 1970s. Features - KIM-1 keypad/LED mode simulator. - KIM-1 serial terminal mode simulator. - Apple 1 serial terminal mode simulator. - Multiple programs including Life, Mastermind, word games, Trek, and more. - Working 6502 Assembler with single-step, memory and register view. - A comprehensive 6502 tutorial system with interactive lessons and reference material. - Shareware! All features are always available without a purchase.

In the Age of Ancients the world was unformed, shrouded by fog. A land of gray crags, Archtrees and Everlasting Dragons. But then there was Fire. And with fire came disparity. Heat and cold, life and death, and of course, light and dark. Then from the dark, They came, and found the Souls of Lords within the flame. Nito, the First of the Dead, The Witch of Izalith and her Daughters of Chaos, Gwyn, the Lord of Sunlight, and his faithful knights. And the Furtive Pygmy, so easily forgotten.With the strength of Lords, they challenged the Dragons. Gwyn's mighty bolts peeled apart their stone scales. The Witches weaved great firestorms. Nito unleashed a miasma of death and disease. And Seath the Scaleless betrayed his own, and the Dragons were no more.Thus began the Age of Fire. But soon the flames will fade and only Dark will remain. Even now there are only embers, and man sees not light, but only endless nights. And amongst the living are seen, carriers of the accursed Darksign.Yes, indeed. The Darksign brands the Undead. And in this land, the Undead are corralled and led to the north, where they are locked away, to await the end of the world... This is your fate.Only, in the ancient legends it is stated, that one day an undead shall be chosen to leave the undead asylum, in pilgrimage, to the land of ancient lords, Lordran.

I’ve had this around for a very long time, but I must have seen something about the Kim and revisited this app - wow, this is awesome!You can revisit the glory days and actually program and run this to see what it was like to be on a computer back then.I can only imagine how crazy it must have been to play lunar lander in the 1970s…very awesome!

Having problems with default keyboard. It wraps beyond screen on latest iOS update running on iPhone X. Makes it very hard to enter anything correctly

Please update to the latest version, as I've put some time into better supporting other screen sizes!

This takes me back to my first 6502. Obviously crafted with much passion and nostalgia for the early home computing era. Thanks John!
