While I agree with Billy Brackenridge that Epsilon is a very nice implementation of EMACS, I'm afraid that he exaggerated some of its virtues. You do NOT receive the sources to Epsilon. You do receive the EEL-coded routines which implement all of the keyboard commands. While this is enough to change the personality of the editor in all but the most extreme cases, there's a truck load of underlying software that you don't have sources for: the EEL compiler, the EEL bytecode interpreter, the buffer virtual memory manager, the window updater, the DOS interface, etc. The interface between Epsilon and EEL is somewhat inconvenient. In other implementations of EMACS one can open a "mini-buffer", stick in a few lines of Lisp or TECO, and execute it with a minimum of overhead. In Epsilon there's more work involved: you've gotta write the mini-buffer to a file, start EEL as a subprocess, load the bytecode file if compilation succeeded, switch back to the buffer you were editing, and execute the command you just created. However, there's no reason why I can't write a new mini-buffer command in EEL to automate most of the steps I just described! All in all, Lugaru Epsilon is a fine product with an excellent support staff behind it. The Info-IBMPC library will be accepting EEL routines, so with luck we will build a collection of extension packages such as was developed for MIT EMACS: mail readers, special editing modes for specific programming languages, and so on. Craig Milo Rogers ------- ------------------------------ Date: 31 October 85 09:00-PST From: HLL%SLACVM.BITNET@WISCVM.ARPA To: INFO-IBMPC@USC-ISIB.ARPA Subject: Janus Ada Compiler A couple of weeks ago I posted a comment on the Janus/Ada compiler. In that note I complained that according to information received from the local distributor, Computer Graphics Center in Palo Alto CA, the C-Pak did not support floating point arithmetic. I have received notification from the primary Janus vendor R.R Software in Madison Wisconsin, that the C-Pak does indeed support floating point, although without the 8087. The floating point library, however, is very limited. I also remarked that statements by Computer Graphics indicated that even the expensive D-Pak and S-Pak appeared not to generate in-line 8087 code. R.R. also informs me that these do indeed generate in-line code. As a result of R.R.'s information, I have decided to give Janus/Ada try. Harvey L.

Steve Walton characterized my previous letter as "hogwash"; he is doing a disservice to potential purchasers of V20s. I have a rather vanilla IBM PC, 640K, 2 DSDDs, no graphics. For those not familiar with Easy-Flow Plus, it is a batch- oriented flowchart generator, which produces a printable ascii file when given a program-like description of a flowchart. I do not know why the V20 will not run such innocent, unstressing software, and I'm only mildly interested in finding out. It is clear, however, that the NEC V20 is not all that compatible with the 8088. - Bob Stine ------------------------------ From: Herm Fischer Reply-To: HFischer@USC-ECLB To: info-ibmpc%ISIB@ECLB Subject: Unix V on 386 runs Unix, Xenix, DOS, and Lotus 1-2-3 code Date: Fri Nov 1 09:45:22 1985 According to the product announcement I got today on Intel's '386 chip, its "System V/386" runs DOS programs under it; they specifically mention that 1-2-3 will operate under Unix on the '386. Anybody know if that means the 1-2-3 user can be at a remote terminal of the '386? Anybody seen this working? They also state that "future enhancements" will include Xenix '286 compatibility, open-NET, and optimized peripheral drivers. [What's unoptimized about the current drivers -- are they cruddy now??] System V includes SDB, for my non-assembler hacker friends. Does all this mean somebody is retailing these products now? (It's all in the present tense, and dated October 1985?) Anybody got one of these babies on an AT plug in card with the Unix V+DOS included? Herm Fischer HFischer@eclb.arpa or {randvax, ihnp4, decvax}!hermix!fischer ps - the manual on the '386 is Intel order number 231630-001. pps - they quote the '387 at 1.8 whetstones per sec (compared to .3 for the '287) ------------------------------ From: Herm Fischer Reply-To: HFischer@USC-ECLB To: info-ibmpc%ISIB@ECLB Subject: Xenix Patch for EGA with Monochrome Monitor Cc: ciaraldi%rochester@eclb Date: Fri Nov 1 23:04:41 1985 I've been asked to comment on the following message regarding patching Xenix for the EGA with monochrome screens. I have not tried this; if it works then that is great, but if it doesn't, caveat emptor. At least the reader will understand what is being done. >From: Mike Ciaraldi >To: hfischer@usc-eclb.arpa >Subject: IBM XENIX patch for EGA monochrome > > >Described below is a patch obtained from IBM to enable XENIX to use a mono- >chrome display with the EGA. The documentation states that the patch was >applied to a version of XENIX dated Aug. 3, which "had a size of 106350" and >that the patch "should work for any version of IBM XENIX". > I don't know if that version is the same as the "Microsoft May Maintenance release", which I received directly from Microsoft as November 84 customer. Anybody know? > >The following is abstracted from hard copy IBM documentation of the patch: > > >Assuming XENIX is already installed using one of the "supported" monitors, log >onto the root directory and enter the command > >adb -w XENIX1 monologfile ... hmmm, this won't work unless the XENIX is replaced with xenix (l/c) > >where the file XENIX1 was copied from the file XENIX, monologfile is where the >log file will go and XENIX.MONO is the following file of adb commands: > >$x tells adb that all input and output is to be in hex > >kdata_dscr+a8/w ffff changes length of display segment for monochrome display > from fff to ffff As users of my EGA Graphics driver know, I patch the segment register for the EGA/color display to permit access to the larger space of the EGA memory. For the specific case here, they are patching segment register C0 (mono screen only) to be longer than the 0x1000 (4k) it is distributed as. They should use the actual length (probably 16k) because this could cause the kernel to crash if software went south and generated a bad address. It appears that, since the following uses EGA color monitor code, the screen refresh for the mono becomes a sliding window in a 16k area (which is what they do for the EGA color and Professional graphics screens). You do get an annoying flicker when scrolling downward and the window hits the bottom and needs to have all the data moved back to the top again! > >hgasp+2/w c0 sets segment address of screen for EGA to c0 instead of c8 Symbols beginning with hga pertain to the "Professional Graphics" monitor, and those beginning with ega pertain to the EGA monitor. Apparently, when the Professional and EGA both used the same code, then the shared subroutine is known by the hga symbol prefix. hgasp is the segment register number used for all screen access by hga and ega prefexed subroutines in the kernel. It initializes as 0xc8. Changing it to 0xc0 switches to the mono screen segment pointer. This would prevent the kernel from working henceforth with either color, professional, or enhanced color monitors. > >hgasp+12/w 4f60 >hgasp+14/w 3a56 >hgasp+16/w 6051 >hgasp+18/w 1f70 >hgasp+1a/w d00 >hgasp+1c/w c0b >hgasp+22/w 2e5e >hgasp+24/w 285d >hgasp+26/w 5ed0 >hgasp+28/w a36e These are the settings for the EGA registers at 3b5. The > values use are defaults for mode 7 from the EGA TRM. > These appear to be the mode 7 initialization stuff from the options and adapters tech ref manual. I prefer my patch, which simply disables the initcrtc routine instead (its been on the net zillions of times), and thus leaves the values as loaded by the bootstrap. That should simplify patching (if it works for mono). >hgascroll+6b?w 3b0 [QUESTION: Is the "?" correct? I've not used adb.] The question mark means that instruction code, rather than data code, is being patched. The 3b0 substitutes probably for 3d0; I believe b is for mono and d is for color. Routine hgascroll is used to scroll the screen (e.g., move the sliding window down in graphics card memory, until it bottoms out, when all is moved back to the top). >egainit+b?w 3b0 >egainit+23?w 3b0 Changes addresses being used for OUT instruction. > This routine appears to initialize the screen. It comes distributed for the 3d0 addresses (color). >hgacpy+18?w c0b8 >hgaclr+1d?w c0b8 Changes some hardcoded segment addresses. The above two routines do not use hgasp to pick up the segment number for color (c8); with expected bad taste, they embed it as a constant, and thus have to be patched even though hgasp was patched above. hgacpy moves bytes from one screen buffer location to another (e.g., when scrolling has bumped bottom, or when characters are deleted in a line). hgaclr clears bytes in screen buffer memory (e.g, when needed for some ANSI escape sequences). > >egacurs+19?w 3b4 >egacurs+22?w 3b5 >egacurs+2b?w 3b4 >egacurs+36?w 3b5 More out instructions. These patches, to the cursor setting routine, change the color address to mono address (3bx instead of 3dx). > >$q Exit adb. > > >Now rename the file XENIX to something else and then rename XENIX1 to XENIX. >Issue a haltsys. Set the switches on the EGA and reboot. That's it. > That's wrong, because upper case XENIX should have been lower case xenix. In addition, one should do all of this to the xenix.fd on the maintenance disk, so that the maintenance disk loads and executes properly. Since xenix.fd is stripped, you can't patch it until you go into /usr/sys/conf and remake it. About 1/2 hour of hacking about. Then, too, be sure to move your new xenix onto the maintenance disk so that when your CMI disk blows up (and it sure will, believe me), your maintenance disk properly builds a system which works with your monitor.

I am told that the '386 will substitute for the '286 in the motherboard of the AT, but you have to wire-wrap up a PAL and a socket. One site I queried said it runs PCDOS, and that they have not tried Xenix. The '386 manual confirms that it will work with 16-bit memories. Any volunteers for the wiring harness? PAL layout? Bootup programs (if any) to place in real 8088 or Xenix-compatible 80286 modes? What speedups have folks who hardware-hacked this up observed? Will the motherboard support 25 or 32 MHz crystals with a hacked-in '386? Herm Fischer HFischer@eclb.arpa; {randvax, ihnp4, decvax}!hermix!fischer ps - it's possible you might void your warranty or burn up something; I'm not suggesting the above action, only curious as to its effect! pps - would this then mean you can run the Unix V/386, described in the Intel Brochure as supporting DOS applications as Unix tasks? ------------------------------ Date: Fri 1 Nov 85 19:45:32-PST From: L. Brett Glass Subject: Bridge programs To: info-ibmpc@USC-ISIB.ARPA One of the most useful bridge-playing programs for the XT comes as part of Turbo GameWorks, from Borland. Not only does it bid a good hand, but it comes with the source! It beats me in duplicate most of the time.... --Brett Glass ------- ------------------------------ Date: Sun, 27 Oct 85 16:00:04 PST From: Ya'akov_Miles%UBC.MAILNET@MIT-MULTICS.ARPA To: Info-IBMPC@USC-ISIB.ARPA Subject: DOS 3.1 RESTORE bug There is a VERY SEVERE bug in PC-DOS 3.1 RESTORE.COM utility. Specifically, if BACKUP.COM elects to create a backup file which straddles more than one floppy disk, RESTORE.COM will sometimes (!) fail to restore the complete file - what RESTORE.COM does is to restore the 1st segment of the BACKUP file to hard disk, and completely ignore the rest of the BACKUP file on the 2nd BACKUP floppy... No warning message is issued by RESTORE, and the disk LOOKS ok when you DIR the files. The only problem is that such files are missing huge hunks off their rear ends, and the usual symptom is the message "BAD EXE FILE" from DOS, or "INVALID OBJECT MODULE" from LIB, at some (future) time when you try to use your compilers... Also, it "would-be-nice" if BACKUP analyzed the file and performed some kind of squeeze (Huffman-code, Compression, whatever works best), and then flags the kind of squeeze used in the 128-byte header prefix which is present in all BACKUP saved files. Hopefully RESTORE would read the header, and then figure out the correct unsqueezing algorithm to use. Please note that the (public-domain) utility ARC.COM, distributed by System Enhancement Associates 21 New Street Wayne, New Jersey U.S.A. 07470 operates in this manner, with a spectacular saving in file space... Finally, has IBM considered replacing the Intel 8088 cpu chip with the (pin-compatible) NEC cmos chip, the uPD 70108-5, which executes up to three times faster, and implements the complete Intel 80186 instruction set? I have seen the Intel 8088 replaced with the NEC uPD 70108 on the IBM-PC/jr, the IBM-PC, and the IBM-PC/xt with spectacular results... ------------------------------ Date: Tue, 29 Oct 85 17:09:10 est From: jcm@ORNL-MSR.ARPA (James A. Mullens) To: info-ibmpc@isib Subject: Dos Path Hints Here is something which I found interesting and useful. If you want to add more directories to an existing DOS PATH, you can do so without retyping the entire PATH over again. Here are 2 (very small) BAT files which do this: FILE: pathb.bat -- adds directory to beginning of PATH set PATH=%1;%PATH% FILE: pathe.bat -- adds directory to end of PATH set PATH=%PATH%;%1 To use: pathb your-new-beginning-path-directory-here pathe your-new-ending___-path-directory-here Example: >path C:\ >pathb A:\ path A:\;C\ >pathe b:\ path A:\;C;\;b:\ >path A:\;C:\;b:\ The effect seems to be the same as the normal DOS PATH command, except that lower case characters are not translated to upper case -- this does not seem to cause problems.

Here are some instructions that might help. In order to modify the status of hidden files so that they may be deleted or otherwise manipulated it is only necessary to change the file attribute byte which is located in the twelfth position of the catalog entry. The possible combinations of that byte are listed below. The following information is excerpted from the IBM DOS Technical reference manual part number 1502346 for DOS 2.10. 01 File is marked read-only. 02 Hidden file. 04 System file. 08 This is a volume label entry. 10 This defines a subdirectory. 20 Archive bit. Used to indicate backup status. If you don't have a disk utility tool like Norton's you can use Debug to change the status. Before you work on a live disk try formatting a new disk with the /s option and then examine the directory entries of the DOS files. The following procedure will show you how to this can be done using debug. Format a disk with the /s option.

I have not been able to find a similar driver with Version 4.1. In particular, the C. Itoh M-8510 printer worked fine with Version 4.0 and does not seem to function with Version 4.1. In Word Perfect's arsenal of printer drivers, is there one that supports the C. Itoh M-8510 ? I know that there is a Proprinter and an 8510 driver (limited support), but these do not function correctly. Failing that, is there a way within Word Perfect to construct a nonstandard driver, or is it just a matter of finding a driver that is more or less compatible? Several faculty members have invested quite a but of time and money, and they would like to know.

Karn) To: info-ibmpc@usc-isib.arpa Subject: PC/IX TTY driver bug There is a bug in PC/IX (IBM's version of UNIX System III for the PC/XT) that has annoyed me for a long time. When a remote user logs out from either of the serial lines, frequently the driver close will hang, disabling the line. The only way to restore it to operation is to reboot the system. I sometimes have to do this several times a day. Does anybody have a patch that will fix this? H E L P!!
