Your POWER C System Disk contains the C Shell, Editors, Compiler, Translator, Linker, Stdio library, Math library and five sample C source code listings: test.c, format.c and format2.c, print.c, sort.c, find.c and wfreq.c. We strongly
advise that a back-up system disk be made from the original system disk and used instead of the original, which should then be stored safely away until' needed to create another back-up.

The reverse side of the system disk is the Library Disk. It contains the Stdlib.l and Syslib.l Function libraries. This Library Disk should also be backed-up immediately and we suggest that you use that work copy of the Library Disk rather than take a chance with the original. Instructions for making back-up disks are contained in your disk drive manual

USI International created Mitey Mo because we felt that sending and receiving information with computers over phone lines (telecommunicating) should be easy, inexpensive, and fun. We wanted a modem and software package friendly enough for the novice user and advanced enough for the most sophisticated user regardless of age. We started with this mighty little modem that combines the latest in technology with the convenience of small size and easy installation. To that we added software written specifically for this modem that gives directions on the screen in plain English. We wrote a manual that is thorough, easy to understand, and enjoyable to read. Further more, we've included phone cables and a function key template in our package to make it complete. Our total system makes it easy for you to get started while at the same time bringing out the full capacity of your Commodore 64.

The programmable logic array (PLA) in the Commodore 64 (C64) is used to create chip select signals from various other signals, e.g., from the current address. These signals control which chip is to be connected to the data bus. Therefore the PLA is responsible to implement the memory map of the C64.

If the PLA is broken, the CPU and the VIC-II1 direct memory access (DMA) can not access the right memory and I/O devices anymore. In this case some chips can not be selected or more than one chip is active at the same time. A total or partial malfunction of the computer is the result. If a PLA is replaced with a part which does not meet certain timing or electrical constraints of the chips connected to it, the computer becomes unstable, possibly depending on temperature or hardware extensions used or may refuse to work at all.

Easy Working Writer v2.00 (Spinnaker) - This version is in .nib format instead of .d64 becuase it has copy protection in tact still.  WinVICE 3.1 works fine with .nib images, so I assume all newer versions will also.

Easy Working Writer is an easy-to-use program containing both a word processor and a spelling checker. A word processor is like a typewriter with expanded capabilities. Use it to write a document, such as a letter, a paper, or a report, just as though you were using a typewriter. But, unlike a typewriter, you can edit and format your document easily and without retyping. With a word processor, once you type the first draft, you only need to type in corrections and additions to your text-you never need to retype the entire document. Formatting, too, is a simple matter-with a single command, you can change from single spacing to double spacing , center a title, boldface a heading, or place a foreign word in italics.

The built-in Spelling Checker helps you find and replace misspelled words before you print your document.

Here's a link to the manual.

The Modern Commodore 64 - by Payton Byrd.  This is a neat little book that Payton wrote back in 2014.  It would be neat to see this updated for 2023.  Here follows the authors introduction:

The Commodore 64 personal computer is still the best selling model of personal computer of all times. Introduced in January 1982, the Commodore 64 was the successor to Commodore Business Machine's wildly popular VIC-20. The Commodore 64 built on the architecture of the VIC-20, but was not backwards compatible beyond simple BASIC games that did not utilize any hardware-specific features of either computer.

In 1982, the world had never seen anything like the Commodore 64 at anywhere near the Commodore 64's price. The closest thing to a competitor for the Commodore 64 was the Atari 800 which was significantly more expensive and lacked the incredible sound capabilities of the Commodore 64. The heart of that sound prowess of the Commodore 64 is the 6581 SID chip, which to this day makes the Commodore 64 a sought-after machine by the Electronic music crowd as well as modern sceners who create incredible arrangements using a single SID chip. You should really listen to this You Tube video (https://www.youtube.com/watch?v=azgZ5Qw8ass) to get a sense of what sceners are accomplishing on the SID and C64 today.

Commodore 64 Color Graphics: An Advanced Guide is a step-by-step guide to creating advanced animated graphics on your personal computer.

The easy to follow yet comprehensive programs can take any beginning programmer into the world of high speed graphics. You' ll be amazed how rapidly you will be able to draw and paint your graphic displays. Machine language data turns time-consuming graphics tasks (such as plotting lines and painting shapes) into high speed magic.

Sequential in structions lead you through advanced graphics techniques. You 'll learn how to quickly reposition shapes on the viewing screen, change their size, and duplicate their shape around a central point. Tools to perform these tricks are provided as well as helpful design ideas and art concepts to enrich your graphics compositions.

The book's final object is to produce an action arcade game using advanced sprite techniques. You a re provided tools to allow you to connect sprites to joysticks, detect sprite colli sions, produce sound, and keep score. When you are ready to crea te your own arcade game you ' ll have a head start with your new game construction too ls.

As a special bonus, appendices include all the tools you'll need to save an actual picture (not your program) on disk or tape and print your pictures on paper with your VIC 1525 printer.

Adventures on Planet Smir 3, Episode 1 Preview, a text adventure for the Commodore 64. Versions for other systems pending. In this game, you have to rescue prisoners from a madman from another dimension and stop him from attaining the secret to fusion. This is just an Alpha version, and Chapter 1 is not quite complete.

Programmed using cc65 and my CBMSimpleIO, Hidden64 and AltInput libraries. You can find these except for cc65 at https://sourceforge.net/projects/cc65extra/files/. It was also significantly optimized using my Cubbyhole and middleman techniques, lots of inline assembler, zeropage, function parameters in global and zeropage, numbers for nouns and verbs, minimizing start-up code and other optimizations, most of which can be found in the provided link.

If you like this program, I ask you for feedback and how to improve it. If you don't like it, I still desire feedback. My e-mail address is rose.joseph12@yahoo.com. If you like this program's style and want to create a text adventure using it, this program is at least currently closed-source, but you can use AdvSkel65 and AdvSkelVic65. These are text adventure skeleton codes around which one can create text adventures. AdvSkelVic65 is the low-end version for small computers such as the Vic20 and unexpanded C16, and AdvSkel65 is for high-end 64k and 128k computers. Most of their features were derived from this program. If you want to see these programs' info without downloading anything, try http://plus4world.powweb.com/tools. They're under Programming.

Commodore 64 BASIC Quick Reference - 1984 by Gilbert Held

If you're an owner of the excellent Turbo Chameleon 64 cartrige for the Commodore 64, you may already know that you can flash the firmware to emulate an Amiga 500 or 1200 w/AGA and turn your Commodore 64 into an Amiga.  One of the few hurdles is emulating an Amiga keyoard with the 64's limited keys.  This archive contains a short article on the keymappings along with images of the keyboard layout.  I also recommend viewing this YouTube video by Redrumloa that explains some of the most used key combos.  Additionally, Espen Skog has an excellent blog post on how to flash the correct firmware to your TC64.  Lastly, you can fin the minimig core and many others at the Retro Ramblings website.
