About VirtualKim - 6502 Emulator

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 — 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 game (or 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.

Added a memory dump view visible once you assemble your own 6502 code.
Your own 6502 code is persisted so you can keep editing and perfecting your program.

* Worked on making the Single Step (SST) mode work better when using the KIM-1 in LED mode.
1.17
2022年12月21日
Redesigned to be easier to use (is that saying much?) with fab new graphics.
1.16

* You can now load paper tape files that are composed of several sections.
* Improved spacing of keypad and keyboard components.
* Added a button to dismiss the built-in help display.
* Tap the LEDs to cycle through various options.
* Improved appearance of the app to suit both light and dark modes.
* Approved by an authentic period-appropriate pet rock.

Our engineering team improved the display for users of smaller iPad devices, and the technical writing pool updated the included manual to the fourth edition. Then they all went out for some cans of Tab.
1.14
2022年02月27日
The "LOAD" panel has been renamed to "FILES", because you can now generate a KIM-format paper tape of memory contents, and so save or share your work by copying the strings. If you do nothing but select save, then 256 bytes from 0x200 will be displayed - perfect for small programs. If you need more control, put the start address (low byte first) in 0x17F5, 0x17F6 and the end address in 0x17F7, 0x17F8 before selecting save. Yes, this is about as awkward as the real thing.
1.12
2022年02月14日
Corrected code editing views to work in dark and regular modes.
Updated the way the controls in the KIM-1 simulation view work to be a little closer to a real KIM-1
1.11
2022年02月11日
Improved the experience (like, groovy) when entering 6502 assembly language.

There's something to be said for a CRT with a fixed number of rows and columns This update tweaks the Assembler editor view to work better with different screen sizes, and the same for the tape import screen.

Updated RIOT code a little, to help other existing programs run.

Our engineers were feeling smug about the challenges they had set you, when someone pointed out they had forgotten to add support for STX and STY in the Assembler. You should have seen their faces! They worked all weekend to get this release out. Enjoy :-)

The 6502 coding challenges are still here, but now our engineers have improved the keyboard support on smaller sized screens. No more excuses: impress your friends and/or significant other by demonstrating your assembly language knowledge, no matter where you are! Who wouldn't be surprised and amazed when you yell out "I can calculate the BRA offset in my head!".

So you think you can code in 6502? Prove it!

The engineering team thinks you're faking your retro-computing fandom status, and has challenged you to complete a few 6502 assembly language tasks to prove you can walk the talk. If you succeed.. well, then the team will give you some more until they're satisfied. Check out the Assembler view for more details.

Also, when they weren't taunting you, they improved the assembler with more error messages, addressing mode bug fixes, and better symbol support. And sped up the virtual 6502.

Good news! Our engineering team has worked weekends and brushed up on their Rodnay Zaks books to update the app and bring you some great new features!

* Fixed! Resolved an issue that could hang the app when multiple keys were pressed
* New! A 6502 Assembler is included! BRK, NOP, LDA, PHA, STA - you know you want to. Now you can!
* New! Ability to enter "paper tape" format files.

* Fixed issue with DA mode not working properly
* Improved support for different screen sizes
* Reversed the polarity of the neutron flow

On-line help fixed.
1.2
