- Frequently Asked Questions
- ==========================
-
- The Right Stuff:
- ---------------
-
- IN JULY OF 1992, WAS COMPUSHOW USED BY THE CREW OF THE SPACE SHUTTLE ON
- MISSION STS-50 TO VIEW DIAGRAMS OF AN EXPERIMENTAL LIFE SUPPORT SYSTEM WHICH
- THEY NEEDED TO REPAIR, WHEN THEIR PRIMARY "TEXT AND GRAPHICS SYSTEM" JAMMED
- AND SCANNED GRAPHICS IMAGES HAD TO BE TRANSMITTED TO THEM FROM THE GROUND?
-
- (Oh, thanks for asking!) The answer is a resounding YES!
-
- A CompuShow support BBS:
- -----------------------
-
- IS THERE A BBS WHERE YOU SUPPORT COMPUSHOW?
-
- While it's not "our BBS", we log on every day to answer questions.
-
- The One-Stop Bit BBS 602-282-9035
-
- To contact me, leave a message for Bob Berry.
-
- Converting to GIF:
- -----------------
-
- HOW CAN I CONVERT OTHER GRAPHICS TO GIF FORMAT?
- WHAT'S "COMPUMAKE TOOLS"?
-
- CompuMake Tools, our graphics conversion utility is described in CATALOG.DOC
-
- CompuShow upgrades:
- ------------------
-
- WHAT'S YOUR POLICY ON UPGRADES FOR REGISTERED USERS?
-
- As we release new versions of CompuShow, registered users are notified by
- mail, and may upgrade for a "nominal cost". For the past couple of years,
- we've held this cost to $9 ($5 for anyone who received the previous version
- within 60 days of the release of the new version). We'll try to stick to the
- $9/$5 upgrade prices as long as we can afford it.
-
- I JUST SAW A NEW VERSION ON A BBS, BUT HAVEN'T RECEIVED AN UPGRADE NOTICE!
-
- New releases of CompuShow sometimes seem to travel at the speed of light.
- Our first step is to post a new release on the One Stop Bit BBS, CompuServe
- and GEnie and then mail copies to our list of BBS SysOps and ShareWare
- distributors. It may take a couple of weeks to mail notices to registered
- users.
-
- Keep in mind that "minor revisions" (like 8.41 compared to 8.40) have small
- changes that don't justify a mailing to all registered users. If you want to
- upgrade to the latest "minor revision", contact me for costs.
-
- Finally, keep in mind that you may have a COUNTERFEIT! (See WHATSNEW.DOC for
- more information about hacked versions of CompuShow.)

- CompuShow and Windows:
- ---------------------
-
- I'M HAVING PROBLEMS USING COMPUSHOW IN WINDOWS
-
- We've had some (limited) success making Windows work. In general it seems
- that Windows doesn't like DOS applications to do graphics, however sometimes
- these will make a difference:
-
- - Make a "PIF" file for CompuShow
- - Run Windows in standard mode, rather than 386 enhanced mode
- - Put FILES=60 in CONFIG.SYS
- - If CONFIG.SYS has EMM386.SYS add "D=48" to that line.
-
- Unrecognized Graphics Files:
- ---------------------------
-
- I DOWNLOADED A GIF FROM A BBS, BUT COMPUSHOW SAYS IT'S NOT A GIF
-
- It was probably uploaded by someone with an Apple computer, and has the
- infamous 128 byte "MacBinary header". A legitimate GIF file starts with
- "GIF87a" (or "GIF89a") in the first six bytes, so this "header" which some
- Apple software tacks on the front end of the file, actually creates a
- corrupt GIF. If the BBS SysOp doesn't have a program for stripping the
- header, we have one (UNMACA.EXE) on the One-Stop Bit BBS.
-
- I KNOW I'VE GOT A LEGITIMATE GRAPHIC IMAGE, BUT IT'S NOT RECOGNIZED
-
- Some programs which claim to produce a standard graphic file, may not
- conform to the official specification. If you find examples that CompuShow
- can't handle, we'd appreciate a copy of the file, so that we can add support
- for the format. However, some compression schemes (such as RIX) are
- confidential, so we can't support them.
-
- Missing Files
- -------------
-
- WHY DOES A BOX POP UP EVERY TIME I RUN THE PROGRAM, SAYING THAT THERE ARE
- FILES MISSING?
-
- At program start-up, (the standard/ShareWare version of) CompuShow checks to
- see that all the documentation and support files are on the same disk and
- sub-directory as the program. Once it finds all the files there and creates
- CSHOW.DAT, you can erase the documentation files, drivers, etc.
-
- UNIX (and some LAN software) don't preserve the original file date and time
- when the files are extracted from a ZIP or other archive. This makes
- CompuShow think that all the files have been modified! (Reset the date and
- time on all files to what's stored in the archive.)
-
- If you move the program to another computer, pass it on to a friend, or post
- it on a BBS, you must include all the original files. In addition, if you
- modify your computer (add memory, upgrade the video adapter, etc.) CompuShow
- will detect that it's not the same computer, and will look for the
- documentation and support files again (so keep a copy somewhere.)

- Video Drivers:
- -------------
-
- I'VE GOT A NEW GRAPHICS ADAPTER, BUT THERE'S NO VIDEO DRIVER FOR IT.
-
- We'll continue to add video drivers as we become aware of new video
- hardware. If you have a new graphics adapter that isn't listed, we may
- already have a driver available for it. If not, but you have the programming
- specs, contact me to see if we can develop a driver together.
-
- I'VE GOT A VGA WITH AN S3 CHIPSET, BUT THERE'S NO S3 DRIVER.
-
- Use the VESA driver for S3 boards.
-
- I SELECTED THE VESA DRIVER, BUT IT ONLY SHOWS A COUPLE OF MODES!
-
- Some manufacturers rush a new board to market without fully implementing
- VESA ("We've got a Windows driver, what more could anyone want?")
- Fortunately, most manufacturers will upgrade the ROM BIOS once it's ready.
- Contact the board manufacturer.
-
- WHAT DRIVER DO I USE FOR AN ATI 'ULTRA'
-
- A lot of people seem to be confused about the ATI 'Ultra' line, thinking
- they have a 1-meg Super-VGA. Most of these models are actually two half-
- cards; a 512k Super-VGA (use the ATI VGA driver) and a 1-meg 8514/a (put
- ATI's version of HDILOAD in AUTOEXEC and use the 8514/a driver).
-
- Printer Drivers (enhanced program):
- ----------------------------------
-
- THE LIGHTS ON MY HP LASER PRINTER BLINK FOR A FEW SECONDS AND THEN IT EJECTS
- A BLANK (OR PARTIALLY PRINTED) PAGE.
-
- The printer may not have enough internal memory to store BOTH soft fonts and
- the graphics data. You need to remove soft fonts from printer memory to
- print graphics. With minimum memory installed, you may only be able to print
- at 75 dpi in <F>ast mode.
-
- WHEN I PRINT IN <Q>UALITY MODE, I ONLY GET A PARTIAL PAGE
-
- You're out of (computer) memory. See "Printing" in CSHOW.DOC for details.
-
- I JUST GOT AN HP DESKJET 500C (OR 550C). DO YOU HAVE A DRIVER FOR IT?
-
- As of 1/93, we've tried for MONTHS to get ink color information through the
- HP Peripherals Developers Program, and a number of DeskJet owners have
- called HP to complain to them and attempt to get the technical information.
- We're still trying to track down the specifications we need, but so far HP
- hasn't been able to provide them.

- GIF files:
- ---------
-
- WHERE DO GIF FILES COME FROM?
- WHERE CAN I FIND A DESCRIPTION OF THE GIF FILE FORMAT?
- WHERE CAN I GET MORE GIF GRAPHICS?
- HOW CAN I CREATE A GIF FROM A PHOTOGRAPH?
-
- The GIF (Graphics Interchange Format), pronounced "JIF", was designed by
- CompuServe and the official specification released in June of 1987. Since
- that time, it has become very popular, due to several factors.
-
- First, GIF uses an efficient compression routine which makes graphics files
- significantly smaller than in virtually any other format. Secondly, by
- design, it's an INTERCHANGE format. Graphics may be created by paint
- programs, fractal generating programs, on scanners or video capture boards.
- The originating computer might be an IBM, Apple, Color MAC, Amiga, or
- virtually any type of computer. Since most computers with graphics
- capabilities have (at least one) GIF display program, the graphics can
- easily be "moved" from one type of computer to another.
-
- As GIF was created by CompuServe, the Graphics Support forum (PICS) is the
- place to find complete, accurate, and up-to-date information about GIF. If
- you're not a CompuServe subscriber, but are seriously interested in trying
- graphics programming, I do recommend subscribing (call 1-800-848-8199,
- operator 229, to sign up or to verify current costs. As of 4/91 it's $39.95
- for a "start-up" subscription which includes a hard-bound user's guide, a
- subscription to the CompuServe Magazine, and $25 credit toward connect time,
- which is currently $12.50 per hour at 1200/2400 baud.)
-
- We've had a number of requests for "disks full of GIFs" or other graphics
- files. While CompuShow has been included on ShareWare disks with GIFs of
- various descriptions, these disks did not come from Canyon State Systems. We
- don't sell or distribute GIFs or other graphics files, with the exception of
- a few samples that are included on the enhanced program disk.
-
- The best place to look for GIF images is CompuServe; "GO GRAPHICS" for a
- menu of graphics forums, containing literally thousands of images and
- related files. GIF images are also beginning to appear in significant
- numbers on other commercial services and a number of BBS's.
