The Portfolio : A Brief Description 8/13/90 For the merely curious this is an unofficial description of the Atari Portfolio. "Unofficial" in this case means written by a user, not by Atari. The Atari Portfolio is a small, hand-held, battery powered computer that operates similarly to a full-sized MS-DOS based portable. The operating system is a subset of MS-DOS commands and in general works the same way. Mass storage is on battery-backed RAM cards rather than floppy disks. Add-on serial and parallel interfaces are used to connect the Portfolio to printers and other computers. The system unit consists of a smaller than normal QWERTY keyboard and a 40x8 LCD display in a clam-shell case about the size of a VHS video tape when closed and weighing in at just over 1 pound. The keyboard has good tactile feel and a speaker-generated keyclick that may be turned off if not wanted. The keyboard is usable for the tasks one might use the Portfolio for, and with practice typing speed can reach 30-40 wpm. The keyboard size has been marked by several reviewers as the Portfolio's biggest drawback. While at first look it would seem difficult to use, there have been no complaints posted on CIS concerning it. The display is a medium-speed super-twist LCD, non-backlit and very clear in most ambient light. The clam-shell design allows the user to tilt the display at any angle from fully closed to open past horizontal with no 'lid-flop'. The brightness is adjustable using a two-key combination. The built-in speaker is mounted next to the display, providing clear sound and phone autodial capability. The autodial is very flexible, providing both local and long distance dialing formats chosen from a menu, and can be set to include a fixed dialing prefix for long-distance carrier access or PBX switching (dial '9' for outside line). Power is provided by 3 'AA' batteries, alkaline non-rechargeable are recommended , providing up to 60 hours of use. An AC adapter is available. A low battery warning gives the user time to change batteries before losing data, and data is preserved for several minutes while actually changing the batteries. The Portfolio contains 128K of battery-backed RAM and 256K of ROM containing 5 application programs and several system utilities. The apps are : Address book : Name, phone #, address, etc. with search, sort and autodialer capability Calculator : general, fixed, scientific, and engineering modes, 5 memories, percentage, factorial, square root, printer output, etc. Diary : Calendar, one-line appointment reminders, single and repeating alarms, search capability Editor : Non-std commands, 40-45K file size limit, autowrap, search/replace, insert/overwrite modes, cut and paste, and an undelete buffer Worksheet : Subset of Lotus 123 v2.x, 123 file compatible, 127 columns x 255 rows There are also built-in file transfer facilities via the serial or parallel interfaces to IBM-PC type computers and via the serial interface to other types of computers. Printer setup and controls are also built into the system ROMs. The built-in software is adequate for most users, providing the most commonly needed features for on-the-go use. Short letters, memos, time keeping and billing are all done easily and quickly. All of the built in apps are available with 2 keypresses or from a menu. There is on-line help available at the press of a key, and a clipboard that works with the editor, diary, address book, and worksheet. The system RAM can be configured as a RAM drive, although it is usually recommmended to store most data on the RAM cards. Cards are available in 32K, 64K and 128K versions. The 128K card lists 125,952 bytes after formatting. Normal DOS directory structure and file naming is used, allowing for subdirectories to be used to organize files. The RAM cards also have their own battery, designed to retain the card's data for 1 year. More software is in the works, both from commercial ventures and from individuals. At the time of this writing, there are several communications programs available for Portfolio to computer hookups and to link to MCI mail, a version of BASIC is in Beta release, a number of small games, some programming tools, and utility-type programs are available.
