Amiga Test Kit 1.20 (Released July 18th, 2022) by Keir Fraser is an excellent tool for diagnossing issues with memory, keyboard, floppy drive, controller ports, audio, video, CIA Chipset, RTC and serial / parallel ports.  Highly recommended!   Comes with an ADF image and CLI utilities.

This program was perfect for diagnosing a sound issue in my Amiga 4000.  I highly recommend this excellent utility!

Zounds is a neat collection of various sound effects created in BASIC with just POKES and FOR loops.  If you need some simple sound effects for a game or demo you want to write in BASIC, this would be a good file to rip those from.

Koala Pictures 3 is a collection of a dozen or so pictures in the Koala format.

Koala Pictures 2 is a collection of a nine pictures in the Koala format.

Koala Pictures 1 is a collection of a dozen or so pictures in the Koala format.

Wall of Sound by Bad Boy of Reflex - This is a pretty neat demo of the wide range of sound effects and music you can produce with the Commodore 64.

Info Writer v1.2 (1989) - Not really sure who to give credit to for this simple noter, but the group Pepsi is mentioned, along with The Syndicate.  Anyway, there is simple instructions included in the program.

HES Writer 64 By Jerry Bailey (1982) - As quoted from the manual:

This program allows you to enter text into the computer via the computer keyboard, then edit and format the text before printing it.

I suppose in 1982 you could look past the crudeness of this program, and were just have something better than a typewriter.  Anyway, here's a link to the manual which is surprisingly detailed.

Story Machine by Spinnaker (1982,83) - So I ran across this CRT image for the Commodore 64 and thought it might be a word processor, but after loading it, it quickly became apparent that it's a children's game that let's you create your own story in a semi-guided way.  After looking at a few screens, it struck me that it was a really neat idea, and that even young children of this day and age might find this not only fun, but educational.

Disk Hacker v1.0 by David Chiles (August 28th, 1985) - There's certainly no shortage of utilities that let you edit the contents of a track / sector on a disk, but I kind of like this one, because it not only has built-in documentation,  butm it can also handle several tracks / sectors worth of data at one go.

The Canonical Collection of Light Bulb Jokes - Yes you read that right, this is a 15K (6K Compressed) collection of nothing but light bulb jokes someone took the time to type into four sequential files.  I feel like these need to be shared with the world, so to wet your appetite, I'll share just one of the dozens of jokes inside the archive:

Q: How many data base people does it take to change a light bulb?
A: Three: One to write the light bulb removal program,one to write the light bulb insertion program, and one to act as a light bulb administrator to make sure nobody else tries to change the light bulb at the same time.

WRITE NOW! 64 (1983) by Computer:Applications Inc (Distributed by CARDCO, Inc.).  Described by the manual as follows:

WRITE NOW! was designed to provide you with an easy to use inexpensive word processor that provides the most desired features of an expensive word processor while being simple to learn and efficient to use. WRITE NOW! is written completely in machine language to eliminate the slowness found in some word processors. WRITE NOW! also uses screen oriented editing so it does not require the cumbersome editing modes required by other word processors.

As far as I know, the program was only officially distributed in cartridge form, but a group called ABA-Soft created a disk version.  This archive contains both a .CRT and .D64 if the program.  The .CRT version was pulled from a ROMset found here on archive.org, and the .D64 version was found here on csdb.dk. The manual for WRITE NOW! 64 can be found here.

 - Thanks to one of our visitors we now have a nice hi-res scan of the manual for this word processor by Cardco for the Commodore 64.  You can find a review of WRITE NOW! here and another here.  You can find the program in CRT and D64 images here.

Ivory BBS v2.0 (1987) by Bill Jackson - Back in the day when I was calling BBSes with my Commodore 64, I always liked Ivory because of the cursor controlled menus.  I don't know if this version had that feature because I only rested out the setup far enough to get screenshots. 

Autorun Tape 64 is a utility that will let you save a BASIC program to tape in a way that will make it auto-start when loaded.  I really hope no one is still using tape storage for development, but if you are.... my condolences.

Sprite Editor-64 is a neat little BASIC program for the Commodore 64 that will let you design sprites, then save them to DATA statements for use in your own programs.  Nothing fancy, but the code is nicely written and pretty well documented with REM statements, so you might find some useful tidbits for your own projects.

80 Columns for the Commodore 64 by Gregg Peele and Kevin Martin - A utility / demo of the Commodore 64 as it would look if it have an 80 column display.  Kind of neat to write some simple BASIC programs that can take advantage of the extra columns.  Just be sure to do a "NEW" command before starting your BASIC coding and you'll have 26,627 bytes of space to work with.

Post Notions is a geoPaint gaphic for the GEOS operating system on the Commodore 64/128.  This particular graphic image came from the Loadstar GEOS Apps 1 disk.  Basically this is a collection of various themed postage stamps (and a Post-It note) that could easily be broken out into a GEOS Photo Album and used in a newsletter.  The included printout screenshot of all the stamps was done using the Star NL10 printer emulation in WinVICE 3.7.  Wouldn't it be cool to have a real (in your hands) oldschool dot-matrix printed newsletter arrive in your "postal" mailbox!?

The programming language C has been in existence since about 1972. It was developed by Dennis Ritchie and Brian Kernighan for the operating system UNIX.  More then 90% of UNIX was written in C.  With the spread of UNIX, C enjoyed greater popularity as well.  Super C now makes it possible to program in C on the C-64 or C-128.  Here is a link to the Manual.

Note: This is an update/replacement for the previous archive.  This archive is a .G64 disk image instead of a .D64 because the .D64 doesn't load the editor due to some copy protection missing.

D71/D81 Writer C128 v1.1 by Ernoman and WdW - With this utility for the Commodore 128 and a Ultimate 1541 II or II+ you can write a .d71 or .d81 disk image stored on your sd-card or usb-stick connected to the U1541 back to a real floppy. As you can see from the screenshot, I don't have an Ultimate device because the screenshot is from an emulator.

See the extended desciption for usage details.  

Here is a link to the projects Github page in case you want to compile the binary yourself.  

Meat-Loaf (Bat Out of Hell) by John Tulley - Saw Meat-Loaf in concert when I was in my 20's, so this hits a particular nostalgia key with me. 

GeoFetch v1.0 by Scott E. Resh (September 3rd, 1989) - With this neat utility, you can grab anything you see on the screen and turn it into a "photo scrap".  A photo scrap is kind of the equivalent to the clipboard in Windows.  Once you've grabbed the region of the screen you want to save and it goes into the photo scrap, you can then use the "Photo Manager" to add that scrap/capture into a "Photo Album".  Photo albums are a collection of up to 60 various images, usually grouped together in similarity.

Note - This game originally came from the Loadstar GEOS Apps 1 disk.

Mind v1.0 by Sean Huxter (February 28th, 1991) - Mind is a guessing game for the Commodore 64 operating system GEOS.  The game is based off the old board game called Mastermind where you had some colored pegs that you put in a row to hopefully match the hidden row at the top of the board.  There are full docs included, so I'm sure you'll find a better description there.  

Note - This game originally came from the Loadstar GEOS Apps 1 disk.

GeoSID v1.0 by Scott E. Resh (October 21st, 1986) - GeoSID is a music player that can play .MUS type SIDs.  There are a few sample SIDs in the archive to test things out.  

I don't really have a category for GEOS sound related apps, so I'm putting this in the Novelty category until I run across more apps of this type.

Loadstar GEOS Apps 1 is a collection of games and applications for use with the Commodore 64 / 128 and the GEOS operating system.  Included on the disk are:

• GeoSID v1.0 by Scott E. Resh (10/21/86)
• GeoFetch v1.0 by Scott E. Resh (9/3/89)
• GeoPuzzler v1.0 by Scott E. Resh (10/21/86)
• GeoKey v1.0 by Scott E. Resh (2/11/90)
• Mind v1.0 by Scott Huxter (2/28/91)
• Hazard v1.0 by Sean Huxter (11/22/91)
• Post Notions (a photo album) by John Elliott (7/25/91)

I will post each of the applications and games seperately in the future with more screenshots. There is a printout of the photo album as a screenshot when you view the detailed description.
