`.In many industries. 5 years is
`hardly long enough to-lock in
`even the barcst of standards.
`Everyone from users to vendors
`to the press argues over subjects
`ranging from keyboard layout
`to user interfaces to graphics
`pmtocols. But as we take an-
`other year-end look at the mi-
`crocomputer business. it's evi-

`dent that traditions. irnot standards. abound.
`In this third annual best-of-the-ycar issue. the editors and writ-
`crs of PC Mag zine get personal about the products and industry
`trends of 1986. We Spend most of the year objectively evaluating
`products. This is our traditional chance to add a healthy dose of
`subjectivity to the magazine. Turn to page lIS for a nobolds.
`ban-ed look at the best'and Worst of 1986.
`Another tradition at PC Magazine is ensuring that our bench-
`ntark tests are tthsolutcly current with the rapid pace ortcchnology.
`For years. users everywhere have relied on the tests to provide
`quantitative. comparative. and repeatable mcasqterncrth.§ In this
`issue. we are introducing Release 4.0 otour benchmark tesl series.
`3|] which contains some familiar benchmark tests and new Eilc Ac-
`cess. BIOS Disk Seek. and DOS Disk Access tests.
`The new BIOS Disk Seek test supersedes the popular Disk Ac-
`cess benchrttark test from Cole International. Both tests report hard
`disk random seek tithe. the most common hard disk perfrj'mancc
`measurement. But our new DOS Disk Access test avoids sire limi-
`tations and uses DOS calls to access disk sectors directly. I 't differs
`from the BIOS Disk Seek test in that it will work withany DOS
`disk. This lets us compare a wider variety of devices. front RAM-
`disks to write-once. read-mostly [WORM] laser disks. '
`It‘s dit'ficutt.to switch tcsls because users want to compare new
`results with the old. With this in mind we're now rctestingexisting
`indUstry-statndurd products. [xu'ticularly the IBM PC. XT. and AT.

`and higher-than-EGA

`multiple compatibility

`
`
`
`resolution of 640 dots horizontally by 350
`scan lines vertically. Three of the EGA
`compatibles reviewed here surpass that.
`with additional video modes as high as 640
`by 480—sometirnes (rather deceptively)
`called PGC resolution. The lBM Profes-
`sional Graphics Controller came on the
`scene at around the same time as the En-
`hanced Graphics Adapter. but it‘s a com-
`pletely different board:
`it has an analog
`output (requiring a monitor such as IBM's
`Professional Graphics Display) and is ca-
`pable of 256 differem colors from a palette
`of 4.096. By contrast. the EGA‘s TI'L
`(transistor-transistor logic) output can dis-
`play only [6 simultaneous colors from a
`palette of64.
`For certain applications. a 640— by 480
`pixel display yields an interesting divi-
`dend. Most small monitors have a dis»
`playable area of about 240 by [30
`millimeters. Divide the width by 640 dots
`and the height by 430 dots. and you‘ll find
`that the horizontal and vertical resolutions
`are identical. Creating a box that's 180 by
`100 pixels will thus be square. that's a nice
`convenience for programmers writing
`their own graphics routines. For anybody
`else. it's merely a coincidence.
`
`:1 the 5 months since our first sur-
`vey of enhanced graphics adapters
`(“Achieving the Standard: 12
`EGA Boards." PC Magazine.
`Volume 5 Number 14). the EGA
`has become commonplace almost
`to the point ofboredom. That's not a com-
`plaint. it's a compliment. The credit for the
`EGA proliferation belongs largely to
`Chips and Technologies (C'I'l). whose
`low«pr1'ced. four-piece EGA CHIPSet al~
`lows hardware manufacturers to assemble
`and sell EGA boards at a fraction of the
`cost of lBM's original. Virtually every KT
`and AT clone that passes through the PC
`Labs comes with its own EGA board based
`on the CHIPSet; some have EGA imple-
`mentations on their system boards.
`Meanwhile. more—adventurous. hard-
`ware manufacturers have been sowing the
`seeds of innovation, and we examine here
`the fruits oftheir labor. They are at the cut
`ting edge of EGA development. where
`boards not only mimic the lBM original
`but add higher-resolution video modes.
`achieve close compatibility with the IBM
`ColortGraphics Adapter and the Hercules
`Graphics Card. and include some unique
`software features. In 5 months. the EGA
`has bloomed into many different flowers.

`
`you use. IBM's Enhanced Color Display
`will not show more than 350 scan lines per
`screen.
`
`Most monitors are locked into specific
`vertical and horizontal frequencies. some-
`times called sync rates. that determine the
`maximum number of displayable scan
`lines. The vertical frequency is the rate at
`which the whole screen is refreshed (about
`60 Hz for most monitors). The horizontal
`frequency is the rate at which each scan
`line is displayed. So. dividing the horizon-
`tal frequency by the vertical frequency
`gives you the number ofscan lines (includ-
`ing some for retrace and for the top and
`bottom borders). The video adapter must
`provide horizontal and vertical sync sig-
`nals at these two frequencies. with very lit-
`tle deviation. The monitor thus limits the
`adapter to a certain number of scan lines
`and effectively constrains vertical resolu-
`tion. no matter what the video board theo-
`retically can do.
`Increasing horizontal resolution is not
`nearly as troublesome because it doesn't
`involve critical synchronization frequen-
`cies. You can easily increase the adapter's
`dot clock frequency without affecting the
`horizontal sync frequency. thereby in-
`creasing the horizontal resolution without

`conservative rating and can generally be
`exceeded.

`As a matter of fact. built right
`IBM‘s EOA specification is the selection
`of an altemate crystal for the EGA's dot
`clock. From there.
`it‘s just a matter of
`loading different values into the CRT con-
`troller registers on the BOA board. {Do-it-
`yourselfers should consult the sidebar
`"Using the BOA Feature Connector for a
`I20-Column Display.“ PC Magazine,
`Volume 5 Number 15. page 298. to see
`how easy it really is.) An EGA manufac-
`turer using a similar technique can stretch
`out horizontal resolution by 50 percent.
`IBM‘s original Color Display operates at
`standard television sync rates: a vertical
`frequency of 60 Hz and a horizontal fre-
`quency of Iii-'5 KHz. The numberof scan
`lines is 262. but the IBM Colorlephics
`Adapter uses only 200 for the display area.
`The CGA dot clock is 14.32 MHz. IBM‘s
`Enhanced Color Display. with the same
`vertical frequency. can operate at two hori-
`zontal frequencies:
`l5.75 RH: for corn-
`patibility with the Color Display and 21.85
`KHz for 350 scan lines. In the 350-scan-
`line modes. the dot clock is 16.257 MHz.
`(The monitor senses which mode to switch
`to by the polarity ofthe horizontal sync fre-
`quency.)
`
`MULTISYNC'IUTHE RESCUE What
`doyoudoifyou want morethan 350 scan
`lines per screen? Go out and buy the NBC
`JC-I4OIP3A MulliSync monitor (re-
`viewed in “The EGA Standard: Monitors
`That Measure Up." PC Mesozoic. Vol-
`ume 5 Number 6). The NEC MultiSync
`can adjtst automatically to a continuous
`range of horizontal frequencies from l5.‘l'5
`KHz (the CGA) to 30 KHz (more resolu-
`tion than the BOA). So. with its vertical
`frequency of 60 Hz. the MulliSync can
`display anything between 200 and 500
`scan lines. In fact. it's actually rated for
`560 lines maximum.
`file NEC MultiSync has proved to be
`quite popularas an EGA monitor. Perhaps
`buyers of the MultiSync believed they
`were making an investment in the fu-
`ture—and so they were. New. way: newer.
`smarter video boards on the m et. they
`can start cashing in.
`
`
`
`VEGA Deluxe and
`QuadEGA ProSync
`In ottr first look at EGA boards. we ranked
`Video~Ts VEGA board (also sold by
`Quadram Corp. as the QuadEGAH as a
`standard CTI implementation with a hard-
`ware problem and a messy CGA and Her-
`cules emulation scheme. But an improved
`model has since appeared. The upgraded
`VEGA Deluxe and QuadEGA ProSync
`(again the same board) boards include two
`new graphics modes. 640 by 480 and 752
`by 4I0. both requiring a NEC MultiSync
`or equivalent.
`The VEGA Deluxe has a mere 20
`chips—very economical. considering that
`this includes the four CTI chips. eight
`memory chips. and a ROM BIOS. Except
`for the socketed ROM. everything is sur-
`face-mounted. The board includes the nor»
`mal 16.257-Ml-lz crystal and a 24-Ml-lz
`crystal for the higher-resolution modes.
`Videofl chose to wire the 24«MH2 crystal
`as if it were an external clock source com-
`ing from the feature connector (that‘s not

`the only way to do it). if you want to attach
`a real feature connector to the board. you‘ll
`have to disable the 24-MH2 crystal by
`switching a jumper.
`
`SQUASHED WINDOWS At the mo-
`ment. the software support for this board‘s
`higher-resolution modes is limited to Mt-
`r'rosofi Windows. But if you don‘t have
`Window. don't won'y: Video-Ts package
`includes Windows [Version 1.03). and
`Quadrant gives you a card to get the pro-
`gram for $30. Video-'3’ is also working on
`Lotus drivers.
`
`if you‘re accustomed to using Windows
`on an EGA. it may look a little squashed in
`the 430-line mode. which uses the same
`fonts and the same pixel resolution for
`icons and cursors as does the BSD—line
`EGA. In theory. Video»? should have pro-
`vided new fonts designed specifically for
`the display resolution. You may prefer not
`having these new fonts anyway. because
`the regular EGA fonts bring more than 35
`percent more character lines into view.
`And. as a nice proof of Wirrdow.r' device-
`indcpendent graphics interface. properly
`designed Windows applications that need
`to draw perfect circles and work in abso-
`lute measurements (such as Micrografx‘s
`BRA W!) adjust to the new resolution with
`no problem.
`Someday. perhaps. a hardware manu—
`facturer will need to provide only a new
`Windows driver with each new piece of
`hardware. Today. however. Video-T‘s
`software support for its new video modes
`must be characterized as weak. Although
`the VEGA Deluxe BIOS includes a
`"hook" for these new video modes. you
`can‘t switch to them using the standard
`BIOS calls: that would have threatened to
`conflict with future IBM video modes.
`Video-'2.l will make available small assem-
`bly language routines designed to get at the
`new graphics modes. for software devel-
`opers and (as a Video-7 engineer told me}
`for “anybody who sounds like he knows
`what he'sdoing."
`Hike this board and I like the Windows
`drivers. but [don‘t like the misleading box
`they come in. People who have explored
`how Microsofi Windows uses the BOA
`have found that Windows uses only 8 of the
`16 colors available in high-resolution
`graphics modes. The program then mimics
