I have nothing against his tentative selection (a Corona, I believe), but would recommend he keep one thing in mind I've found very important. I run a Gulfstream Micro .. an 80286 CPU (8MHz) with PC-DOS 3.1. The sheer processing speed has totally spoiled me! I absolutely HATE to work on anything less .. even the 8086 clones and fast boards don't match it. Now I'm a programmer .. I tend to get bitten less by "processor- sensitive timing loops". I don't have or need color or graphics, altho I suspect I'd have NO problems there .. compatibility is excellent. I hear the cries of those considering which add-on fast-CPU board (or V20/ V30/etc) to add, with boards still in the multi-hundreds of dollars, and incompatibility biting them left and right. If I were you, compadre, I would consider a system running as FAST as possible, with the FASTEST memory available (preferably expandable to the full 640 Kb on the mother board like my Gulfstream). I'd look at hard disks from access time as well as capacity .. surprising how you can get double or better the acess speed (as well as greater capacity) for a relatively small increase in price or just by looking around. I would NEVER work on a 4.77MHz system, only grudgingly at 6MHZ, and kinda envy the new 10MHz no wait state CPUs and mother boards coming out now.

I am integrating some ATs and decided to use the Tall Tree products, largely because of recommendations on this list. First of all, I was upgrading my AT, since I find that 2MB of memory just isn't enough for me. So, here's what I started with: IBM PC/AT, 9 Mhz, 512K motherboard Core Int'l 70 MB hard disk AST Preview card AST Advantage with 1.5 MB This system has been running this configuration for about 6 months with no problems. So, I get the JRAM boards along with an appropriate amount of Hitachi 150ns 256K RAMs. Being a do-it-yourselfer, I populate the JRAM board with 2MB and pull the Advantage card, installing the JRAM in its place. Things immediately don't work - the memory diagnostic gives unknown codes (at least the Tall Tree documentation doesn't list them) and things are generally wierd. MEMTEST points to all 8 banks being bad. So, I manage to clear some errors by RAM swapping, but things are still wierd. So, the next morning, I call Tall Tree. Tall Tree, in their documentation, say that they have recommended chips, and to call them for those recommendations. The person on the phone sez "Well, it should work at 9Mhz, what chips are you using?" I sez Hitachi. He sez, "tough luck, Charlie, we have found that Hitachis don't work in our boards" and then proceeds to list (in order of preference): Toshiba Fujitsu NEC OKI Micron Tech So, I get home and I have 5 banks of OKI memory and 1 bank of NEC memory in my Advantage card. Out goes the Hitachi (actually, into the Advantage goes the Hitachi), and in goes the 6 banks of approved memory. I plug the JRAM in and, lo and behold, I'm getting the same errors. Well, I did what I should have done in the first place - I dropped the clock speed to 8 Mhz. Voila! Everything works. So I then sez to myself "self, there can't be THAT much difference between RAM chips, can there?"...so I populate the remaining 512K on the JRAM board with Hitachis. Everything still works. So, I'm now happy as the proverbial pig - I got 704K DOS, JBOOT, JSPOOL, JDRIVE and all that happy stuff. And I'm a heck of a lot wiser when I see flakey memory problems on an AT. The bottom line is - use the recommended chips and don't push your clock speed. If you're gonna operate above 8 Mhz, you probably oughta go to 120ns RAMs. I'm not, since I have a substantial investment in 150ns parts.

Unfortunately this language support produces quite a lot of confusion. 1. The program interchanges the two keys #^ and <> .This seems to be a relict from the older keyboard, where this two keys had different locations. 2. The programs interprets everything it sees in the new "language". It is sometimes rather difficult to read e.g. mail from the US , because exclamation marks are interpreted as (U with dots), and the ampersand comes out as a paragraph sign. Of course, writing may be even impossible without a key translation table. Does anybody have any experience with this stuff, or a better version, or an idea how to change the program ? Naturally, this should be easier for No.1, while No.2 seems to be a rather principal problem.

I got a hand-me-down Davong hard disk as my first computer at work here, and after too long of struggling with the flaky Davong software and the copious lack of documentation I found a reasonable solution. Golden Bow Systems (PO Box 3039, San Diego CA 92103, (619) 298-9349 ) makCs a product called "FiXT" , $80, that allows you to treat your Davong, Datamac, Great Lakes, Percom, Tandon 5112, Tecmar, TallGrass, VR Data, and a few more drives & controllers as if they were standard, normal DOS 2.x or 3.x hard disks. You can get rid of the old Davong software entirely, and use DOS Format to format the disk. (All the data is lost in the process, tho, so you should use Copy to backup the hard disk to floppies.) If you have an older PC, with 64K on the motherboard and a serial number under 300,000, you need to get the hard disk BIOS from IBM, "BIOS Kit ROM Module", P/N 1501005, to boot from the hard disk. Rather than spending $xx and waiting for it to come in, I used Skip Gilbrech's BOOTCFG and told it to initialize the optional hard disk roms. (You can find BOOTCFG on IBMSW on CompuServe, on the Wipcus BBS in Ann Arbor, MI at (313) 663-1835, the VOR RBBS in California at 1-415-994-2944, or on fine bulletin boards everywhere. You don't need it if the roms are newer. The machine has been passed on from my posession once again, and it's still in use. That hard disk is slow, eh?

At the time I got it, I was able to get my hands on Davong's Multi-OS psuedo PC-DOS operating system. I was never really pleased with it (it was a real dog) and was really happy to discover Golden Bow Systems. Golden Bow is in San Diego and has developed a chip that you place in an empty socket in the motherboard. This little gem allows you to boot off the Davong as it it was a real Xybec, Seagate, etc. hard drive. It supports DOS 2.0 thru 3.1. My only remaining complaint about the Davong drive is that it is NOISY! However, I guess I can live with that.

I do not think that this is the case. For one thing Epsilon is too slow for this to be true. I recently set up my monochrome with an EGA running in 43 line mode. I then ran Epsilon with the -vl43 option. Oh yes, I am using NANSI.SYS to go to 43 row mode ([=43l I think). This works fine. Since the 80x43 screen is not memory mapped and Epsilon works, I assume that Epsilon uses the BIOS.

It provides a device driver that allows PCs to be active participants on an Appletalk network and utilities for Laserwriter arbitration and use. It furthermore provides a file system translation between the two environments. I have been using a 1 Mb RAM disk on my AT as a shared disk with three Macs. The Macs see this thing as an icon, and throughput is almost winnie-like. The AT is not a dedicated server, I can use the Mac disks just as easily. For those of you unfamiliar with Appletalk, we ran the network about 300' using plain 2 twisted pair w/ ground. Throughput is 250kb Mac to PC and 800kb+ PC to PC. The best thing about this network is the price. I do not know what has announced to date about this, but it will be seriously less than most any other net. This is something worth waiting for.

He is not on the net, but I will be happy to try to forward any replies to my net address. FASTBACK - DANGER - BUG WARNING I have had serious problems with Fastback Version 5.03 from Fifth Generation Systems. Of 64 backup disks the Fastback Restore utility choked on 53 - locking up my computer and requiring power down to reset. When I called Fifth Generation they were courteous and knowledgeable, but a promised fix has not arrived in over 2 weeks. I will update this message when it does arrive. My problem, according to Fifth Generation, is that some Compaq Desk Pros have disk controllers that their programs cannot deal with. They did not mention this problem in printed or disk documentation. Documentation states that the program works on IBM PC, XT, AT, and Compatibles. If Compaq computers aren't IBM compatible, what is? Will this program work on all IBMs (surely they all use the same controller)? I noticed some odd behavior when first using the program. But seduced by the promise of quick and easy backup protection I convinced myself that it was minor. Several disks backed up and restored properly so I felt safe. A month later after formatting my hard disk, I found I was not. Before considering purchase of any backup system, consider the following questions. How can I be sure that the restore function will work when I need it most? Would the software company tell me if their product may lose all my data? Does the software license absolve the software company of all responsibility if their product wipes me out? Is the saving of a few minutes backup time worth jeopardizing my business records? Could flashy performance get me too?

It's composed of a NEC D3126 3.5 inch Winchester Disk Drive and an OMTI 5510 Data Controller. The formatted capacity of the drive is 20.25 Meg, 17 sectors of 512 bytes per track, 4 tracks per cylinder, 611 cylinders per drive. It is very quiet in operation and pretty fast. It uses one slot in my Olivetti M24, but because it's 1.6 inches thick, the slot next to it cannot accept a full size board anymore. The controller includes the IBM PC/XT BIOS. A ROM at C000:0000 can be used to preformat the disk and to set the interleave factor. It comes preformatted for an IBM PC, with an interleave factor of 6. (My Olivetti M24 needs an interleave factor of 3). When installed, DOS 3.0 and DOS 3.1 did not recog- nize the disk. DOS 2.11 did not have any problems with it. I pre-formatted, FDISKed and FORMATted the disk using DOS 3.1, and it ran without problems. (It cannot be used under DOS 2.11 anymore because of FAT incompatibilities). The controller can handle one more diskdrive. The price was very high, however, about US$ 1,400. But in Europe we are usually ripped off when buying things that are relatively new on the market. The specs do not show how much current is drawn from the 12V supply, only that it draws .5Amp from the 5V at maximum. Heat dissipation at average running is 13W. Other specifications are: Specifications my own tests. minimum seek time 18 ms 22 ms average seek time 85 ms 84 ms maximum seek time 215 ms 213 ms average latency 8.4 ms --- start/stop times (max) 15 sec MTBF 20000 POH The card comes with one year of warranty. The only odd thing I found yet is that the DOS disk parameter table (INT 21H function 32H, PC Tech Journal May 86) shows the disk to have 3 heads in stead of 4.

Plouffe" Subject: Leading Edge & Sperry Clock Utilities The file EDGCLK.ARC has been uploaded to SIMTEL20 and located in PD:EDGCLK.ARC. This ARC file contains the source and executable files for two utilities that will be useful to owners of Leading Edge, Model M and Sperry PC personal computers. (Maybe Model D also. See below.) They are: LE_MCLK Reads the on-board battery backed-up clock and sets the current clock to its values. This code is intended to be executed in your AUTOEXEC.BAT file. The .COM file is only 28 bytes. SETCLK Sets the date and time of the battery backed-up clock and simultaneously updates the current clock. The function of LE_MCLK is built into DOS 2.11 as supplied with the machine, and the v2.11 COMMAND.COM will update the battery clock with the internal DATE and TIME commands. So, if you stick with DOS 2.11 you don't need these utilities. However if you upgrade your DOS to 3.xx, you will find that it has no knowledge of the on-board battery backed-up clock. These utilities will then do the job and restore full function to the use of the battery clock. The programs use an undocumented feature of the on-board ROM BIOS. The Time-of Day interrupt (INT 1AH) has four additional functions beyond that of the IBMPC ROM BIOS. This is fully explained in the documentation. I suspect that the DOS 2.11 supplied with the Leading Edge, Model D is identical to the one supplied with the Model M. If so, then the ROM BIOS must also provide the same functionality for the additional INT 1AH functions - so this code will probably work with a model D also. Someone who has a Model D please let me know.

I have an OLD (believe me) PC with an added hard disk. This PC has been running on DOS 2.1 and I load the hard disk by booting 2.1 from floppy and running a 32 byte hard disk "init" program. The init program does some setup, calls the hard disk ROM (CALL C800:0003), and then calls an INT19. This works well with DOS 2.1. Now I want to go to DOS 3.1 and all is not so well. The hard disk ROM loads and does it's thing appropriately, but the INT19 bombs the system. I get interesting messages too. (PARITY CHECK [1-2] sometimes, most often nothing) I thought that perhaps DOS was trying to read disk info from the hard disk and getting confused upon reboot, but have no way to run FDISK or FORMAT under 3.1 since I can't boot the hard disk from it.

SHULL" Subject: MS-DOS 5 Reply-To: "CHRISTOPHER E. SHULL" Does anyone have an informed opinion as to when DOS 5 will be available? My own guess is 1st Quarter 1987, but I haven't heard anything more specific. Will IBM force MS to delay until after the Christmas holiday season so they can unload as many PC's as possible before they are completely obsolete? Also, while it is common knowledge that DOS 5 will allow 80286 machines to address up to 16 MBytes of RAM, will this RAM have to be in any particular format? Will EMS and/or EEMS still work in their kludgy fashion, or will they be required, or will they not work at all, or what? The reason I ask is that I have to add memory to 15 PC/AT's that already have 512 K, and I only need to get them to 640 K immediately, but what to assure compatibility with DOS 5.

We do this with a "CTTY COM1" command, and then connect to the PC's serial port with either tip(1) or Kermit. We find that at any speed faster than 1200 baud, we get a large number of "Error reading COM1--Abort,Retry,Ignore" messages. We also find that we cannot run Kermit on the PC reliably for file transfers unless we do a "CTTY CON" before starting Kermit, which we do via a batch file which re-does "CTTY COM1" after PC Kermit exits. Anyone else having similar problems, know of a fix, or have an idea of what's happening? Is CTTY stupid? Does it not recognize XON/XOFF flow control? Please respond directly to me, as I don't read Info-IBMPC regularly. If I get a solution, I'll post it back to the net.

King" Subject: Tandy 3000 / MS Word / EGA Problems I forward the following problem description for one of my colleagues to see if anyone can offer any suggestions or similar experiences. ----- I have two different IBM PC/AT type systems that I am using with Microsoft Word and the Microsoft Mouse (bus version 5.0). At my office I have a 6 MHz IBM AT with the IBM EGA (128K) and Enhanced Color Display, and I have a system at home which consists of a Tandy 3000HD, an IBM EGA (128K), and a Princeton Graphics HX-12E Monitor. The system at work performs flawlessly in all modes. At first, I had a problem with vertical patterns of colored dots appearing on the screen, but this was fixed when Microsoft sent me some patches to the mouse driver. Since then, I have installed Mouse Driver 5.02 (which came with Word 3.0), and Mouse driver 5.03 which I just received. Both of these also work well. My system at home is a different story. When I try to use Word in the graphics mode with the mouse, the screen develops a jittery double-image effect. I get a second flickering image displaced about 1/2 a character to the right of the normal image, almost as if the display system is about to lose sync. Initially, with mouse driver 5.0, the problem occurred only after the system had been on for a little while. When I applied the patches which cleared up the colored dots at work, the flicker at home became permanent. My first suspicion was a hardware problem, particularly because it seemed to be warm-up related. Having two systems at my disposal, I performed several experiments. The problem does not occur at work with either EGA card, but it occurs in the Tandy with both EGA cards. The problem occurs with my current HX-12E Monitor, and an earlier one I had. I do not have the problem if I run Word in Text Mode with the mouse, or if I run Word in Graphics Mode without the mouse. PC Paintbrush works fine with the mouse, and the high resolution graphics in the EGA works very nicely with Paintbrush and 2 other programs I have (but which don't use the mouse with graphics). The problem exists with both Word 2.0 and 3.0, and Mouse Drivers 5.0 (with or without patches), 5.2, and 5.3. Because the problem only exists when I run Word in Graphics Mode with the mouse, it suggests a software problem which is somehow aggravated by the high clock speed of the Tandy (there is also 1 less wait-state in the 3000 than in an AT). All of my other software works fine with this combination of hardware, and all of your software works fine except in this one mode. On the other hand, it's possible that the IBM EGA just won't quite work in the Tandy in this mode. It almost worked with Mouse Driver 5.0, which indicates that the software is running the EGA close to the edge in the Tandy, and the higher versions seem to have gone over that edge. I've been struggling with this for 6 months now, and it is a subtle problem, but I hope you can help me. I can't believe that I'm the only person who is having this problem, given the popularity of your products, the Tandy 3000, and the EGA. I also think there must be a software fix, even if it is in some sense a hardware problem. It may be that this is not a problem with Microsoft Word or Mouse, but with my other hardware. The IBM EGA has a reputation for being "flaky", and it may be that I have two bad boards. It may be that one of the EGA clones is known to work with Word and the mouse in the Tandy, and I could try that. I specifically bought Word because of its EGA support, and I would hate very much to have to abandon it. ------ Roger King MIT Lincoln Laboratory ------------------------------ Date: Tue 1 Jul 86 12:40:45-PDT From: Ted Shapin Subject: Returning to the dir a batch command was called from This is one way to issue a batch command from any directory, possibly change to another directory and change back to the original directory. Is there a simpler way to do this? First, we need to create a file with just the letters "cd " and no return line-feed at the end. We can do this with DEBUG by reading in a file with the proper debug commands. DEBUG >\foo\ret.bat <-- this adds the current dir name cd \foo rem The next line proves that we changed to another directory echo cd [ here you would do whatever you need to do ] c:\command /c ret <-- this runs the batch file to change back to the original directory Ted Shapin. ------------------------------ Date: 3 Jul 86 19:21 EST From: davidsen%kbsvax.tcpip@ge-crd.arpa Subject: Printer Redirection I want to redirect the printer (PRN) to the 2nd parallel port.

Writing a multi-tasking operating system for the IBM PC-AT , I am facing the following problem : I would like to catch characters requested by the different processes (via INT 21 , AH = 3F) in order to direct characters to the different process buffers I handle . The problem lies in the fact that DOS does character buffering somewhere inside its giant source . I would like to manipulate with the DOS buffers . Has anyone ever done that ? Can anyone send me the address where the DOS buffer is kept ? Does anyone know anything interesting about how DOS handles input characters ? Many Thanks In Advance Yair Kurzion.

Here's my problem: when I boot my machine, I can be at the monochrome monitor/keyboard or the color monitor/keyboard. The keyboard and monitor lines have been switched but I have no way to determine this. Therefore, I want to issue the message: color or monochrome? on BOTH displays, get the response, and set the appropriate mode (I will have a remote-boot button at the remote display). Using the BIOS call 16H option 0 has strange behavior: if I am on the monochrome display, the BIOS routines do not let me set any color mode. If the equip_flag switches are not 3 (mask 30H) (color display as default) then it sets the mode to 7 no matter what I ask for. if I am on the color display, setting mode 7 causes the color display to lose sync and never regain it (at least until I get a 'mode co80' command issued). One obvious solution is to write directly into the memory areas for those cards, but what I'd like to do is what the 'mode' command does. How does it do it? I'm not enough of a DOS COMMAND.COM expert to figure out how to start tracing this one down. I program in Lattice C 3.0. Any help will be appreciated. joe ------------------------------ Date: Sun, 6 Jul 1986 18:30 EDT From: James H.
