![]() Thus, the second 64K bank is generally free for use as a RAM disk. Most programs, including Applesoft BASIC, are designed to use only the first 64K bank. Each bank is addressed from location 0 through location 65535. The Apple IIc has 128K of RAM organized as two separate 64K sections or banks. If you could use the RAM disk for program storage, you could use the conventional disk drive entirely for data storage. A RAM disk sounds like some futuristic propulsion mechanism, but it's really just a section of Random Access Memory that, with the proper software, works like a disk drive. Rather, it is an electronic drive known as a RAM disk. Did you know that your Apple IIc has a second built-in disk drive that will hold about 60K of information? Of course, it's not a regular mechanical disk drive. But wait-there's another alternative you should consider first. One answer is to buy a second disk drive. So a single-drive system can be a bit limiting in terms of storage capabilities. If a disk contains programs that total about 40K, then only 100K remains for data. ![]() ![]() Typically, people use a disk to store both programs and data. An Apple disk holds about 143,360 characters, or 140K bytes, of information. One of the conveniences of the Apple IIc is its built-in disk drive. The actual program listing and complete instructions for use will appear next month in Part 2. In addition to demonstrating the RAM disk and subdirectory options with ProDOS and an Apple IIc, this article presents a utility for rapidly copying a number of programs from the floppy drive to the RAM drive. ![]()
