Part 2 USING THE MULTIRAM C CARD Using MultiRam C shows you how to use MultiRam C for massive Desktop space with AppleWorks, how to use the card as a RAM fast disk drive, and describes hardware and software that you can use to enhance the usefulness of MultiRam C.[...]

Chapter 4 APPLEWORKS & MULTIRAM The MultiRam C Card releases the power locked up within AppleWorks! AppleWorks has become the best selling program for the Apple //c and //e. AppleWorks real potential, however, has not been realized as AppleWorks usefulness is constrained by the small 55K Desktop apace an ordinary 128K Apple //c provides the pro[...]

4.2 APPLEWORKS & MULTIRAM 1. Make backup copies of the Startup disk, Program disk, and AppleWorks memory expansion disk (the front of the MultiRam disk). For your convenience, the Filer, Apple’s ProDOS disk copy program, is included on the Utility side of the MultiRam disk (beck side) to make your backup copies. You may use COPYA on a DOS 3.3[...]

APPLEWORKS & MULTIRAM 4.3 lower right corner does not show this loss because the overlay manager does not reserve apace for all AppleWorks program segments. AppleWorks will allow data files to overwrite all but a few key program segments option two loads in during the boot. Program segments can be overwritten because AppleWorks will search for [...]

4.4 APPLEWORKS & MULTIRAM Desktop Space and File Limits AppleWorks supports a total of 12 files and 55K of memory for the Desktop. The MultiRam C modification permits the Desktop to expand to 413K. The number of files allowed remains at 12. Clipboard Line/Row Limit The Clipboard Is a temporary storage area in AppleWorks that allows the transfer[...]

APPLEWORKS & MULTIRAM While this increase makes AppleWorks much more useful for small to medium size records, files with large record sizes (AppleWorks allows records to be as large as 1K) can exceed even MultiRam’s memory before reaching the 5,100 record limit. Please read the section “Working With Large Files” in this chapter for more i[...]

4.6 APPLEWORKS & MULTIRAM The actual time an action on a large file takes say be as little as half the time AppleWorks shows or as much as twice the stated time. The differences in actual versus approximate stated times will vary depending on the type of file in use and the operation called for. For example, a sort on a large database file coul[...]

APPLEWORKS & MULTIRAM 4.7 The sizes AppleWorks will report for files greater then 255K will be incorrect. Figure 4.1 shows a catalog of a ProDOS hard disk subdirectory with one AppleWorks file “SAMPLE” in the directory. ProDOS reports the size of a file in blocks. A block is 512 bytes or 1/2 of 1K. Therefore the size of the file is 621 bloc[...]

4.10 APPLEWORKS & MULTIRAM Word Processor Flies AppleWorks limits word processing files to 2,250 lines. This is the equivalent to 45 single—spaced, typewritten pages with standard margins. While AppleWorks supports print lines up to about 140 characters, it only displays about 74 characters on a screen line. Given these restrictions, you can [...]

APPLEWORKS & MULTIRAM 4.11 When working with a very large worksheet in memory, it is a good idea to leave an empty border of 2 or 3 rows or columns at the top, sides and bottom. As with the word processor, the date moving commands (Hove and Copy) won’t always operate as expected at the edges of the worksheet. For example, if you fill every ce[...]

4.12 APPLEWORKS & MULTIRAM To merge files 1. Load all files (in this example, files ONE, TWO, and THREE) into memory. Press [Open—Apple]+Q (Desktop index). A window will appear in the center of the screen showing the names of all the files in memory. 2. Decide which of the files you went to merge all of the records into. We will use ONE am th[...]

APPLEWORKS & MULTIRAM 4.13 In our example, the destination file (ONE) is modified by the addition of another category. so that none of the data in the merged file (THREE) is lost. Further, the categories in ONE will be rearranged so that it is in the same order as THREE. Note that they don’t have to be the same names nor match upper or lower [...]

4.14 APPLEWORKS & MULTIRAM Preparing for Segmentation Saving very large files does involve some planning and time when you are using standard Apple 5 1/4 inch disk drives. The first requirement for using large files and floppy disk drives is disks and lots of them. Don’t consider starting a session with one or more large files without having [...]

APPLEWORKS & MULTIRAM 4.15 2. Format the required number of data disks with the same volume name. From the main menu choose “5” to go to other activities and then select “5” to format a blank disk. Enter a disk name no more than 15 characters long. After the first disk is formatted, press the space bar to return to the disk formatter. R[...]

4.18 APPLEWORKS & MULTIRAM The MultiRam file segmenting procedure does not affect AppleWorks internal backup safeguard as long as there is room on the disk for the temporary file being saved and the old, existing file. But if there is no inns on the disk to save the temporary file, even though the file could easily be saved to a blank disk, the[...]

APPLEWORKS & MULTIRAM 4.19 If the first disk you load is not the first disk in the sequence, unpredictable results can happen as only the first file contains critical information relating to the segmentation. At best, error messages that make no sense will appear. At worst, AppleWorks will hang or crash. Be very careful to always correctly and [...]

4.20 APPLEWORKS & MULTIRAM Switching Between Files On The Desktop The multi--file Desktop is one of the beat features of AppleWorks. With only 55K of standard Desktop apace, however, it can be a nuisance to have to remove a 45K database tile from the Desktop in order to sake room for a 12k word processor document or spreadsheet. And with 55K. t[...]

RAM DISK EMULATION 5.1 Chapter 5 RAM DISK EMULATION The MultiRam C Card can be made to look like a high capacity disk drive to DOS 3.3, ProDOS, and Apple Pascal operating systems. After MultiRam C is setup as a RAM disk, it can be used like any disk drive except it will work many times faster since it is RAM based and has no mechanical parts. Depen[...]

5.2 RAM DISK EMULATION Preparing The Program The RAM disk program is on the Utilities side of your MultiRam disk. You will need to save this program to another disk as it cannot be used directly from the Utilities disk. The Utilities disk uses the ProDOS operating system. Programs stored on a ProDOS disk cannot be directly transferred to a DOS disk[...]

RAM DISK EMULATION 5.3 Always end a session with the RAM disk by copying any files on the RAM disk that you wish to permanently save to a floppy disk. Programs can also be directly saved to the RAM disk from memory. Similarly, programs can be loaded into the Apple’s memory from the RAM disk. CAUTION: When using a RAM disk, DO NOT create a file gr[...]

5.4 RAM DISK EMULATION Running the preceding program will create and save a text file to disk that when EXEC’d first runs the RAM disk installation program, runs FID, and then passes values to FID so that all the files on the disk. including P10 and the RAM disk drive program, are copied to the RAM disk. The only thing to add to the disk are the [...]

RAM DISK EMULATION 5.5 Programming Tips DOS 3.3’s Read/Write/Track/Sector routine, RWTS, can be used to directly read or write to the RAM disk. If you wish to use RWTS with the RAM disk, follow all standard protocols and do not call into RWTS; enter RWTS from the top of the routine. The standard or custom RWTS Input/Output Block (IOB) and its sec[...]

5.6 RAM DISK EMULATION PRODOS RAM DISK The MULTIDRIVE.PRO program converts your MultiRam Cs memory into a fast electronic disk drive for the ProDOS operating system. The ProDOS RAM disk is recognized by ProDOS as one large ProWS volume. Specifications The MULTIDRIVE.PR0 RAM disk program creates one ProWS volume named “/RAM,” located in slot 3, [...]

RAM DISK EMULATION 5.7 Using the ProDOS Filer, which is included on the Utility side of the MultiRam disk, you may transfer the MULTIDRIVE.PRO program to any ProDOS formatted disk. To run the program, simply type “MULTIDRIVE.PRO” after the disk the program is on has booted and has displayed the Applesoft “]” prompt. If the program is on a d[...]

5.8 RAM DISK EMULATION Transferring Files Files must be copied to end from the RAM disk using a file copier. The Filer’s “Copy Files” commend is easily used for this purpose. The “Copy a Volume” command, found under the volume commands, will not work. The Filer program is included on the Utilities side of the MultiRam disk. Always end a s[...]

RAM DISK EMULATION 5.9 First, boot the other disk you would like to run using the Control+[Open—Apple]+Reset key combination. DO NOT turn off the Apple and then turn it on again to boot the desired disk aa all files on the RAM disk will be lost. Run the desired programs from the disk you booted. Second, when you are ready to return to use the Pro[...]

Some of the more useful products are described in this chapter. HARD WARE All hardware products tested with the MultiRam C card have been compatible : modems, mouses, printer cards an[...]

6.2 HARDWARE AND SOFTWARE COMPATIBILITY Before buying a large floppy drive or hard disk drive, check to ace that all the operating systems you would like to use on your Apple (ProDOS, DOS 3.3, and Pascal) work on the drive. Further, if you use copy protected commercial software. be certain that the drive will run the software you now use or check w[...]

Part 3 PROGRAMMING THE MULTIRAM C CARD Programming the MultiRam C card explains how to use the //c’s standard auxiliary memory and how to manage multiple auxiliary bank addressing for the MultiRam C Card.[...]

chapter 7 PROGRAMMING AUXILIARY MEMORY MultiRam C’s memory is addressed by The Apple as standard auxiliary memory. Therefore, when any 64K bank of the MultiRam cards memory has been switched into place as active auxiliary memory, standard auxiliary memory addressing techniques can be used to access MultiRam C memory. This section briefly reviews [...]

7.2 PROGRAMMING AUXILIARY MEMORY BANK SWITCHING Because the 65C02 can address only 64K of memory at one time, in order to utilize the I/c’s auxiliary memory, the computer must switch between the 64K RAM of the main memory and the 64K of auxiliary memory. This is called “bank switching. Soft switches are locations which control which of the bank[...]
