IS there a software package to aid someone writing a non-fiction children's book; a guide to a country in the Middle East? The graphics I am looking for include an Arab on a magic carpet, animals, children, food, and the like. The book should also includethought bubbles in the margins. NAME AND ADDRESS SUPPLIED The latest word processors for Microsoft Windows, such as Ami Pro 3.0, WordPerfect 6.0 and Microsoft Word for Windows 6.0, come with libraries of built-in clip art - or line drawings of various graphics. The same goes for graphics packages, such as Corel Draw, Harvard Graphics and Aldus Freehand and Adobe Illustrator. The Macintosh versions of the above packages also carry clip art. You should be able to find the graphics you need in one or all of these products, and you can use them to draw your own thought bubbles in your book's margin. The programs are not difficult to use and all come with a thorough built-in on-line help system. Clip art libraries can also be found in CD-ROM form and as shareware and freeware on computer bulletin board services. In addition to clip art, you may want to look at using CD-ROM products, such as Microsoft's Encarta interactive encyclopedia, for background and photograph ideas for your book. I HAVE a 386DX 33-MHz with a 120-MB hard disk (a Maxtor 7120AT) that is stacked with Stacker 3.0. My hard disk is full and I want to add a second hard disk, but I am not sure how to configure it. Stacker has created a Stacker D drive. If I add a second drive, it will also be named D in the set-up program. Will this cause a problem? Must I unstack the C drive first before installing the second drive? Can I use a Conner CFA340A (340 MB) as the second drive? Is it compatible with my Maxtor 7120AT? PETER TAM Wan Chai When a data compression utility such as Stacker is installed on a system, it allocates a portion of your drive as virtual drive area and assigns it the next logical drive name. Thus, for a hard disk with a C assignment, Stacker makes D the next assignment. When you install your new drive, the system will recognise and assign it a D placing in ''set-up''. Stacker, when run, will then work out that the new drive is there and reassign new identities to the virtual drive areas. You should not need to un-stack your C drive first. IN response to the article headlined ''Internet link offers public cheap E-mail'' in last week's Technology Post, we have had many enquiries for more information on how to access the Internet in Hong Kong. There are two local Internet service providers who give users full access to the information super-highway. Supernet, the company featured in last week's article, is one, and the other is Hong Kong Internet and Gateway Services (HKIGS). Both offer a choice of connecting to the Internet via a dedicated leased line (a solution only economical to big companies with vast volumes of data to pass on to the Net), or via a standard telephone line. Called a dial-up connection, the latter can be opened by anyone with a personal computer, modem, communications software and a good-quality telephone line. For a dial-up connection, Supernet charges a $175 joining fee and $25 and $10 per hour of logon time during peak and low hours respectively. A minimum charge of $175 a month is levied. HKIGS charges dial-up users $100 to join, $100 a month as a service charge and $20 per hour spent on-line. Although the charge structures offered by these companies differ somewhat at the end of the day, they often add up to about the same. Using the backbone services offered by these two companies, some local BBSs offer E-mail only access to the Internet for as low as $6 an hour. For more information on Supernet, telephone 358-7924 or fax 358-7925. HKIGS can be reached by telephone on 527-4888 and by fax on 527-4848.
