Drive G is a Type II PC card drive that is similar to a disk drive on a PC. You<br />

can use memory or input/output (I/O) cards that comply with PCMCIA<br />

(Personal <strong>Computer</strong> Memory Card International Association) Standard 2.1.<br />

You use memory cards to store applications or data files. You use I/O cards<br />

(such as a modem card) to connect the reader to another device for<br />

communications. For help, see Chapter 4, “Using PC Cards in the Reader.”<br />

Note: Drive F is a placeholder since there is only one PC card drive on the <strong>JANUS</strong><br />

<strong>2020</strong> reader.<br />

Managing the Reader’s Memory and Disk Space<br />

You can store applications and data on the reader’s drives. The memory you<br />

need for an application usually depends on the application and the types of<br />

memory available on the reader. Use these guidelines to store and run<br />

applications on the reader.<br />

Data storage Use drive E to store data if the files are less than 256K. If you<br />

need to store data files larger than 256K, use a PC card in drive G. For help on<br />

selecting a PC card, see Chapter 4, “Using PC Cards in the Reader.”<br />

Applications and look-up tables Use drive C or E to store all applications and<br />

look-up tables. You can use drive C to store applications that do not write to<br />

the same drive and read-only tables. Use drive C to store files that do not need<br />

to be changed often. If you need more memory or disk space, use a PC card in<br />

drive G. For help on selecting a PC card, see Chapter 4, “Using PC Cards in the<br />

Reader.”<br />

Large applications You may develop a large application that requires more<br />

conventional memory than you have available on the reader. You can remove<br />

any device drivers and TSRs that you do not need on the reader. For help, see<br />

“Making More Memory Available on the Reader” in Chapter 3. You can also<br />

purchase a DOS extender and develop your application so it can run using<br />

both conventional and extended memory.
