The C64 (Electronic Games)

Product Information

Commodore BASIC 2.0 is used instead of the more advanced BASIC4.0 from the PET series, since C64 users were not expected to need the disk-oriented enhancements of BASIC4.0. The company did not expect many to buy a disk drive, and using BASIC2.0 simplified VIC-20 owners' transition to the 64. [78] "The choice of BASIC2.0 instead of 4.0 was made with some soul-searching, not just at random. The typical user of a C64 is not expected to need the direct disk commands as much as other extensions, and the amount of memory to be committed to BASIC were to be limited. We chose to leave expansion space for color and sound extensions instead of the disk features. As a result, you will have to handle the disk in the more cumbersome manner of the 'old days'." [79] Reid, T. R. (February 6, 1984). "Coleco's 'Adam' Gets Gentleman's 'C' for Performance". The Washington Post. KB ( 9 KB Commodore BASIC 2.0; 7 KB KERNAL; 4 KB character generator, providing two 2 KB character sets) used the 128's bank switching to store program code separately from variables. Variable values would be preserved across program executions if the program was started with the GOTO command.

The best Commodore 64 games are brought to life by the machine’s 8-bit brain. It seem’s crazy to be talking about an 8-bit home computer when the PS5 is now running on 256-bit. That’s progress for you!

Even though Target: Renegade is a side-scroller, it appears in an isometric 3D view, giving it an edge over other games in the genre at the time. If I had to describe it, I’d say it’s a little like the original Donkey Kong game with ‘Jumpman’ mixed in with Frogger and a dash of Jungle Hunt. From a modern programming point of view, the earlier versions of Commodore BASIC presented a host of bad programming traps for the programmer. As most of these issues derived from Microsoft BASIC, virtually every home computer BASIC of the era suffered from similar deficiencies. [11] Every line of a Microsoft BASIC program was assigned a line number by the programmer. It was common practice to increment numbers by some value (5, 10 or 100) to make inserting lines during program editing or debugging easier, but bad planning meant that inserting large sections into a program often required restructuring the entire code. A common technique was to start a program at some low line number with an ON...GOSUB jump table, with the body of the program structured into sections starting at a designated line number like 1000, 2000, and so on. If a large section needed to be added, it could just be assigned the next available major line number and inserted to the jump table. Naman, Mard (September 1989).

Line numbers can range from 0 to 65520 and take five bytes to store regardless of how many digits are in the line number, although execution is faster the fewer digits there are. Putting multiple statements on a line will use less memory and execute faster.

C64 supported multicolor sprites enabling it to create amazing visuals. Also, its Sound Interference Device (SID) chip produced great sounds. In 1984, Commodore released the SX64 (see the upper image), a microcomputer C64 with a built-in monitor, floppy drive, power supply, and 40.4×21.6 dimensions. The Public Response
