-
- COCO64 is a program for the Commodore C64 computer that will allow the
- user to translate and view HiRes pictures generated on the Trs80 Color Computer.
- These images are usally processed with MAXCMP or PIXCMP on the CoCo, and
- uploaded to networks or BBS systems. All that is required for the C64 user
- to view the picture, is a terminal program that can download the seqential
- ASCII data (such as CBterm/C64) and the COCO64 program.
- The resulting HiRes image may be saved in a Doodle file on your disk.
-
-
- Operation:
- ----------
-
- You must first download a CoCo picture file to your disk drive. You may
- READ the data into your terminal's RAM buffer and save it, or DOWNLOAD it
- directly to disk depending on the ability of the terminal program you are
- using. The data should be saved in ASCII (no translation) format, and not
- translated into PETASCII. The picture information is in the form of a SEQential
- file that is a basic program for the Color Computer. This program itself
- has no meaning on the C64, however, the picture data is included in the program,
- and COCO64 reads and decodes this data.
- Once you have the SEQential file on disk, you load and run COCO64.
- You will get the title screen, then after 5 seconds you will be prompted for
- the name of the file to read in. Simply enter the file name and press <return>.
- (Or enter "HELP" for a help screen.)
- COCO64 will read in the file, and then the screen will clear. The border will
- flash as the picture is decoded. When the image is ready it will be displayed
- in black and white on the screen.
- If, while the file is being read in, you see:"Double Lenght Image"
- it means the picture is two screens long! When the image is displayed, you may
- scroll the image up by pressing the F1 key, or down by pressing F7.
- To dump the image to disk in doodle file format, you press the + key
- for a positive dump, or the - key for a negative dump. The image on the
- screen at the time will be sent to disk, and will be useable by Doodle or
- other graphics programs.
- After a dump, you may press any key except <return> to review the
- picture. Pressing <RETURN> will EXIT the program. You may then RUN it again
- to process another picture file.
-
-
- SPECS:
- ------
- COCO64 is a hybred program. It is part basic and part ML. Its basic
- lines should NOT be altered, as this will crash the program.
- COCO64 reads in the data from the MAXCMP/PIXCMP program, and looks
- for 2 things first off:
- 1) The word "ARROW" as used in the line "Use up and down ARROW to scroll the
- picture." -This line is included in all files that are double lenght and
- this keyword signals COCO64 that the image is to be decoded in double lenght.
- 2) The word DATA1. This signals the start of the picture data in the program
- and tells COCO64 where to begin decoding.
-
- At this point, the data is read in, converted and displayed on the C64.
-
- Errors:
- ------
- If you should get a "STRING TOO LONG" error, just enter: GOTO200 and hit
- <RETURN>.
- This will restart at the point COCO64 left off. Ver 1.1 has been altered to
- greatly reduce this error over Ver 1.0.
-
- If COCO64 fails to find the keyword ARROW to signal a double lenght file,
- you can force COCO64 to decode in double length. When you get the "Standby.."
- message, press the RUN/STOP key and then enter: OS=3:GOTO200 <RETURN>
-

- Much thanks to Art Flexser for providing the specifications for the
- MAXCMP/PIXCMP format for the Color Computer.

-
- Items of interest:
- ------------------
- 1) CBterm/C64 - A super terminal program that will allow downloading of the
- COCO picture files (and much much more!). Avalible in DL2 of the CBIG sig.
- Please read the file CBTERM.TXT (in dl2 of CBIG) for the current index to
- CBterm files.
- 2) Doodle utilities (display, print, etc.) are avalible in DL2 of CBIG.
- 3) COCO picture files can be found in DL2 of the COCO sig. Go COCO to get there.
