64 Logo
All the disks here are in D64 format, also called a disk image. They can be used with any Commodore emulator on your PC or Mac. They can also be transferred to a real Commodore disk with the right equipment or software. Google ‘Commodore PC transfer’ or ‘Commodore Mac transfer’ or visit a Commodore forum for many different options. If you have a software/manual archive please feel
free to include any of these items on your site. They are here to share
and because I haven’t been able to find them anywhere else. If you do add
them to your site, please let me know, so I can remove things from here
if they become easily available elsewhere. Thanks!

Commodore 64 Logo - Turtle Graphics by Terrapin: In elementary school, we had Commodores for a short
while, but then they were replaced with Apple IIe’s. I discovered many
of my first favorite games on the Apple, games like Snooper Troops, Odell
Lake, and Oregon Trail. One great activity we had was learning the Logo programming language with the Apple IIe version of Terrapin Logo. We programmed a ‘turtle’ to draw shapes and play games on the screen, which I enjoyed very much.
At home I had a Commodore 64, which I enjoy tinkering
with to this day. Mostly I use an emulator on my PC but it’s always fun
to use the real thing from time to time. As a kid, I really wanted Terrapin
Logo to play with at home, but could never convince my parents to pick
up a copy. (I still have the advertisements after all these years!) I was
somewhat placated by a full-featured “Turtle Graphics Interpreter” written
by Irwin Tillman, which I found in a computer magazine called COMPUTE!’s
Gazette. It was a fascinating glimpse at the inner workings of Logo, but
as it was written in BASIC, the turtle moved excruciatingly slow (on today’s
emulators, he can whiz along pretty fast, though!) Later, at a flea market,
I found a cartridge called “Turtle Graphics II” from Human Engineered Software,
written by David Malmberg. (Malmberg regularly wrote for the leading type-in
magazines.) It was a little complicated to learn but decent; it had a nice
manual, and both low- and high-resolution modes. (The first cartridge,
Turtle Graphics, was a low-res version released for the VIC-20, also by
Malmberg.) Also I discovered another low-res logo-like language called
“Elmer the Turtle, Turtle-Tutor for Tykes” by Peter Crosby, in RUN magazine.
Recently I found a wonderful book called “Learning
With Logo” by Daniel Watt. (He also wrote a Logo book geared to the C64,
which I don’t yet own.) It’s very well written and approachable, and I
highly recommend it to anyone interested in the language. To use the book,
I downloaded an Apple IIe emulator, as well as Terrapin Logo for the Apple
II, and began playing around with the turtle and re-discovering my youth.
I was even able to finally type and play a game program I’ve been hanging
on to for years called “Logo Olympics – Light the Torch!“ from Teaching and Computers Magazine. (Also found in the Teaching and Computers Book Series; Holiday Computer Activities.) Still, the thought
of Commodore 64 Logo nagged at me. So I began searching around for Terrapin’s
Commodore 64 Logo, which was written by Leigh
Klotz, Jr., (also the programmer of the Macintosh implementation of Logo.)
Searching the internet for the term “Logo” is pretty overwhelming; it brings up a lot of stuff. I discovered several non-working copies of final versions of Terrapin’s C64 logo, and a site that offers “Version A,” an early and very buggy version of C64 Logo. Giving up on finding a copy on the internet, I purchased a real copy of Logo, “Version 8,” from an auction site. From this, I was able to make a working copy of Logo for the Windows VICE Commodore emulator, and I was also finally able to read and share the manual. Unfortunately, due to the copy protection method used by Commodore, I was unable to make a disk image for other emulators or for transfer to a real disk at this time. News Flash! I’m elated to announce that as of November 2008, I can now finally offer Version 8 for download as a disk image! Special thanks to the kind person who sent me a working disk image of Version 8! Thank you, El Comunicador! Now you can use C64 Logo with any C64/C128 emulator or even transfer it to a real disk to use on a real C64/C128! Version 8 is super fast and appears to have most of the
features of Terrapin’s Apple Logo. It includes sound commands and something
the Apple version doesn’t have: sprites! You can download both the software
and manual below. (I still offer Version A in the zip archive below, but
I recommend using Version 8 instead. )
Here you can download an archive containing two Commodore
64 Logo Programming Language manuals, and five disk images; Commodore 64
Logo Version 8, Commodore 64 Logo Version A, the Logo Utilities Disk, an
Example Disk, and the Learning With Logo Work Disk. Even without the LWL
book, you can play with and explore the programs on the LWL disk. These
disk images are in .D64 format and can be used with most Commodore emulators
as is, or they can be copied to real disks and newer media such as the
new Commodore accessible flash drive! (As a side note, keep in mind the
proportions of an emulated screen are often different from a real screen.
There is a command in the Logo manual to correct this, search the manual
for the term .ASPECT.) If you just need the manual, you’ll see the original
official pack-in manual called A Language for Learning, as well as a children’s
primer called Kids Working With Logo. (Both of these are included in the
archive.)
Additionally there’s Turtle Graphics Interpreter from COMPUTE!’s Gazette and it’s instructions, Elmer the Turtle from RUN magazine and it’s instructions, and the HES Turtle Graphics II manual in case someone has the cartridge and needs a manual. (Unfortunately, I don’t have the means to make an emulator cartridge image of TG II. Also, I don’t own TG I so I can’t share it’s manual.) If you know of other versions of C-64 Logo, please let me know! NOTE!! If you already downloaded Version A and created any work disks with it and want to use them with Version 8, you may need to rename some files. If the .LOGO extension is missing or truncated from your files, rename the files to include the full .LOGO extension. For example, “LIGHTTHETORCH.LO” would become “LIGHTTHETOR.LOGO”. Beware of creating duplicate names! The command is: OPEN15,8,15,”R:newname=oldname”:CLOSE15. I recommend making a backup before doing this and testing each file afterwards.)
