To: WISCVM.WISC.EDU!GKN3M2@IRISHMVS.BITNET, pur-ee!info-ibmpc Subject: PC Clones I own a Heath/Zenith 158, an XT clone. Compared to the XTs at work, which I unfortunately had the need to dig inside, the Zenith (or Heathkit) looks and feels like a much better engineered machine. The EMI/RFI levels are far better, the screen never "snows", the CPU card is separate and removable from the chassis, there are 3 more slots, and the power supply is 168 watts standard (I operate 2 floppies and one hard at the same time, with all slots filled). The ROM BIOS does not include BASIC, but rather Zenith felt that the user would prefer to have a diagnostics menu and disassembler instead. I have NEVER had trouble running any PC program; but Zenith does provide two DOS utilities that will make the extended BIOS operate just like IBMs. The ROM monitor program is directly accessable either at power-up, or by the key combination. Upon power-up, the machine is ready to boot the disk in 3-5 seconds (compared to IBM's 10-20). The MS DOS does NOT include BASIC, getting away from IBM's idea of a home "personal" computeer, and more user/programmer/business computer. The DOS instead includes many useful utilities, such as search-for-a-string-in-a-file, search-for-a-file, convert-tabs-to-spaces, display-an-extended-sorted-directory, etc. The programmer's tool kit even includes one of the best screen editors that I have ever used (I regularly use EMACS, VI, SE, and score of others). The tool kit also includes a COMPLETE on-disk listing of ALL of the BIOS, as well as VDISK.SYS and ANSI.SYS (so that you can modify them yourself), plus version 4 of the macro-assembler. The documentation for the operating system has been totally rewritten by Zenith, and comes in binders twice to three times as thick as IBM's, with full explainations and examples. The video card has dip-switches to make the card emulate either IBM's color graphics card, monochrome card, or the EGRA. Outputs include RGB and com- posite video (B/W) with absolutely NO snow. True to Zenith's reputation, the composite video output displays a TRUE gray-scale on a monchrome monitor, even taking into account IBM's BROWN. I have found that Flight Simulator looks better in color mode when I use it one my monochrome monitor than in its monochrome mode. The floppy controller card can operate 4 drives directly, even though there is only room to mount two in the machine (since they would require power anyway, an external chassis would be perfect). All slots are full length slots, a total of nine of them (one for the CPU card, eight for the rest of the system). The keyboard is faster, smoother, with larger key-caps than IBM's, although it still uses the standard IBM layout (except the the large L-shaped key). The whole keyboard is faster, and runs with a separate programmable processor, that has a key-repeat that speeds-up the longer that you hold a key down, and learns to adjust to your typing. The key-click is generated by the keyboard processor, and can be shut-off ( combination). The NUM-LOCK and CAPS-LOCK keys both have LEDs in them to show what status they are in. During the summer, I used my Zenith keyboard on my employer's XTs with no problems, but with better output. The machine itself, when purchase under the Heath version, includes HUGE service manuals, that make repairs and service as easy for the layman as riding a bicycle. It comes in two full-size 3-inch binders, with everything that you would want to know. The documentation for the machine and the DOS are so clear and precise, that I got more knowledge of the IBMs at work after reading Zenith's documentation, than I did when I had read IBM's documentation. From the rumors that I heard (no validation), Zenith paid some good bucks acquire some propreitary knowledge from IBM, apparently only in the interest of making there machine as compatible as possible. Zenith has re-engineered the whole system, and did a fine job of making a machine more IBM compatible than IBM themselves. The machine was designed to incorporate the state-of- the-art equipment and software available. Zenith also markets a version of Microsoft's Xenix (called Zenix?), and CPM. I have used Kaypros, Compacts, and even Zenith's Z200 machine, and found that they are for more inter- changable in many enviroments, that even IBM isn't (thats what I mean when I say they are MORE compatible than IBM themselves). Note too, that the Z150 series are the ONLY non-IBM machines allowed to call themselves an IBM XT in the ROM code (a one-byte identification). It took Zenith 4 years (1985) to come up with there clone for the XT (they had an 8088 machine, the H/Z 100 in 1980), but as far as I can tell, they corrected as many of the complaints people had of the IBM, and still be compatible, as they could. I am a EE student here at Purdue University, as it only took two days of looking at the documentation and the PC boards in both the XTs at work, and the Zenith to appreciate the Heath Engineers in St. Joe, Michigan, and all the fine work they put into their machine. The IBMs at work have had break-down, service, and dealer support problems, my Zenith has only had one CPU problem (I didn't solder the kit well enough), and Zenith directly and openly supports every machine they make directly, with separate lines for software, DOS, and hardware. Remember, if no one else has told you, Zenith's Z100 machine is a better piece of architecture than the IBM XT is; even though both with use MS DOS and use the 8088 processor -- I hae been able to do more with my roommate's S100 bus Z100 than I can with my IBM compatible. Like I have said, I have used many IBM type machines (the school used to buy Leading Edges), and fell that in the IBM XT class, the Zenith 158 is the way to go. By the way, if you are looking for an IBM AT class machine, the new Kaypro is the way to go -- they are only ones allowed to identify themselves as an IBM AT in ROM. Also note, Zenith's 148 looks and acts an awful lot like Compact's machine, and even identifies itself as such -- any clue where the money went here? I am sorry if this is long, but I wanted you to get a GOOD look at what I am talking about when I say that the Zenith is the machine that you want to go for. - sgh ------------------------------ Date: Wed 19 Feb 86 12:36:27-PST From: Ted Shapin Subject: Finding bad blocks on disks To: info-ibmpc@USC-ISIB.ARPA Phone: (714)961-3393; Mail:Beckman Instruments, Inc. Mail-addr: 2500 Harbor Blvd., X-11, Fullerton CA 92634 I had the following experience with the 20 meg IBM supplied hard disks (not CMI) on two brand new AT systems. I ran into I/O errors reading files for an application on one system. Running the advanced diagnostics flagged the same tracks written on the sticker on the hard disk. Running chkdsk did not pick up any bad tracks. Running Tom Jennings SCAV30 (scavenge program) found some ADDITIONAL bad blocks and locked them out. Then running CHKDSK a second time, converted these bad blocks to files, FILEnnn.CHK, which I left so those blocks wouldn't be allocated by DOS. The second system showed the same type of thing. SCAV30 showed bad blocks that were not picked up by either the advanced diagnostics or CHKDSK. ------------------------------ Date: Tue, 18 Feb 86 13:15:43 EST From: Kenneth Van Camp -FSAC- To: cameron@Jpl-VLSI.ARPA cc: info-ibmpc@usc-isib Subject: ARC50.COM ARC50.DOC is on the Simtel20 archives, as well as the executable. --Ken Van Camp [Please be specific when mentioning files on simtel20, as to include the directory name.

PC-MacBridge (from Tangent Technologies, 5720 Peachtree Parkway, Suite 100, Norcross, Georgia 30092, 404-662-0366) is a combination of a short board and software which puts a PC on an AppleTalk network. We have two Macs, one Mac XL, the PC AT, and a LaserWriter networked together. The chief use for PC-MacBridge is to allow one to print on the LaserWriter, although if one is willing to buy Macintosh mail software (I forget the name of the package), one can theoretically have mail capabilities between work- stations on the network. The software included with PC-MacBridge allows one to print documents from several popular word processing programs, including WordStar and Multimate. One can easily set things up to print plain ASCII files. I have to say that we have been rather disappointed with PC-MacBridge, given its cost of $595. Two major problems have surfaced: (1) PC-MacBridge seems to fail miserably most of the time when trying to print files greater than 32K in length. The files I have tried to print were converted by PC-MacBridge into PostScript files, so the original size of the text files were rather less than 32K. (2) We have on many occasions experienced PC-MacBridge interferring with the actions of Macintoshes on the network which are in the process of printing when we give the command for PC-MacBridge to print. At least once, PC-MacBridge's actions resulting in a Macintosh being "kicked off the network". More typically, if a Mac is printing, say, a ten page document, and then we give the command for the PC AT to print, the printer will not complete the Mac's document before allowing the PC AT's document to begin printing. This is truly incredible, since all PC-MacBridge has to do is wait until the LaserWriter is free. We have heard that they are "working on it"! Given that the release of the software we have is V. 2.1, it is hard to justify such problems. Until such problems are fixed, caveat emptor. ------------------------------ Date: Tue, 18 Feb 86 22:41:00 est From: BACS Access To: net.micro.pc%indiana.csnet@CSNET-RELAY.ARPA Subject: Multiple Serial Ports Cc: mod.computers.ibm-pc%indiana.csnet@CSNET-RELAY.ARPA, I am using a Zenith AT clone with Xenix and am interested in attaching several more serial ports.

Please reply to me and I will pass on the information. "I have another question to pose to anyone (I was about to say listening!) reading.... Are you aware of any micro software (IBM or Apple) written for ADULTS who are learning to read and write. I promised my gang at Project Read (part of the California Literary Project part of a nationally funded literacy push right now) that I would ask. Seems there is a puddle of software for CHILDREN newly gaining literacy but it is very inappropriate for our adult illiterates. The Menlo Park library where my group is based has various types of Apple and IBM micros that we could start using with our students but, sigh, we need some software. Any and all ideas and information would be appreciated." ------------------------------ Date: Mon, 17 Feb 86 03:46:47 -0100 From: Tom Ivar Helbekkmo To: Subject: QNX Query Does anyone out there have any experience with the QNX operating system for the IBM PC?
