Mac to 64 - by Siamak Ansari - 2/88 (With epson printer driver [Compatible with STAR printers]) This program lets you view macpaint graphic files on commodore 64 plus save & print option. as you may or may not know macpaint files are 576 (horizontal) by 720 (vertical) dots. in comparison 64 screen is 320x200 dots. in this program the 64 screen acts like a window to the larger mac screen. Load and run this program. at the prompt enter macpaint file name (works with both prg and seq files). after loading, it will switch to bit map mode and the 64 screen will be at the top left corner relative to the mac screen. (when the directory is being listed, pressing pauses the listing. press any key to resume listing.) The following is an explanation of command keys available to you: 1) Scrolling the four cursor keys ,i.e., left, right, up and down keys will scroll the picture in the respective direction. the scrolling in horizontal direction is 8 dots (1 byte) at a time.however, scrolling in the vertical direction can be set to 1 or 8 lines at a time by pressing "1" or "8" key, respectively. this is useful for "fine tuning" for the save option explained below. the "r", "l", "u" and "d" keys are for "big jumps". when pressed they move the screen to the right, left, top and bottom edge of mac picture, respectively. the "c" key positions the 64 screen at the center of mac picture. 2) Color change when the picture is first displayed the colors are set to cyan & black.macpaint files are monochrome and this choice of colors is usually good. but if you wish you can change the color of fore/background using f1 and f3 function keys. pressing f5 inverts the picture. pressing f7 changes the border color. 3) Zoom pressing the "z" key toggles on and off the zoom feature. this is a crude zooming effect achieved by skipping every other raster line. the resolution is somewhat reduced but it will let you see more of the mac picture on the 64 screen and get a feel of what the whole picture looks like. all scrolling commands mentioned above are also functional in the zoom mode. i recommend that you use 1 line scrolling while in the zoom mode. 4) Save you can save at any time whatever you have on the 64 screen as a normal doodle file. this is done by pressing the "s" key and program will then prompt for a file name. don't forget the "dd" prefix for the file name if you intend to use it with the doodle program. 5) Print although you can only see a small part of the mac picture on your 64 screen, you can print the whole picture out. the printer option is activated by pressing the "p" key. the print routine is for epson fx-80 or compatible and star printers. the print density can be selected at either 72 or 80 dpi (dots per inch). printing at 72 dpi density is recommended for correctly proportioned output. also you have a choice of printing the positive or the negative image. to abort printing at any time, just hold down a key until printing stops. 6) End while in bitmap display press . you will be prompted for 3 options: to load another mac file, to return to bitmap screen or to end the program. ************************************************************ This program is public domain. ************************************************************ ADDITIONAL COMMENTS by Scott K. Stephen (01/26/90) There are two version of MACVIEW for the C64, MACVIEW64.EPSON and MACVIEW64.1525. They both function identically. The only difference in the two version lies in the printer that they support. MACVIEW64.EPSON supports EPSON and STAR and compatible printers. MACVIEW64.1525 supports the 1525 and MPS801 printers. There is also a MACVIEW specifically for the C128. I can't say very much about this verison since I don't have a C128 to test it on. However, my presumption is that it function also most like the C64 version, but with a better graphics resolution. So the above documention may still applies for the C128 version......enjoy.
