It takes both 8" and 5.25" disks and will convert the documents from word processor format A to word processor format B. Thus, if your friend knew which PC-based word processor that he/she would be using, the files could be directly converted. While the Keyword box itself is expensive (about $8000), I am sure that there are a number of service bureaus that would do the conversion and at a reasonable cost.

Danowski asked how to get the Z-171 internal modem to work YTERM. To use the modem with other software you must first set the modem to external. 1) Go to the World Map 2) Select Set-up 3) Using the arrow keys move the cursor to the Modem Block 4) Change Internal to External This will make the internal modem Com Port 2, and the serial port Com-1 Now just set your program to Com2 and use the standard Hayes AT command set. (ie ATTD 555-1212 to dial with tones) I use Kermit with the following in the MSKERMIT.INI file: SET PORT 2 SET BAUD 1200 SET TERM HEATH-19 Note the port must be set before the baud rate. Hope this answers your question.

Indeed, the Bios does not, nor does Dos. A couple of observations: 1) If you have some other device that wants to use that interrupt, just disable interrupts on the printer (the normal case, I believe) and use it. Since no one else uses it to print, you win. 2) The real problem with interrupt driven printer drivers boils down to how the interrupt signal gets generated. From the printer's point of view, all it does is raise (or is it lower?? it has been a long time) the "ack" line. In fact, it does this as a rather short pulse. On the parallel interface, the interrupt is generated from signal *level*, rather than transition, and the pulse from the printer is not latched. Turns out the pulse is so short as it make it probably not possible to guarantee detection of all interrupts (i.e., new int comes in before the interrupt controller is reset and so the new int gets lost). I eventually gave up on writing an interrupt driven printer driver. This suggests that care be given to any device being built to use the parallel port to make sure the "ack" pulse is long enough. chris ------------------------------ Date: Mon, 29 Dec 86 17:42:32 EST From: ANDERSEN Subject: PCjr Add-Ons I recently purchased a "jrHOTSHOT Multi-function Upgrade Plug-in" from ES Quality Products, 5311 Mango Blossom Ct., San Jose, CA 95123 (408) 224-5574. The jrHOTSHOT is a small circuit board that plugs INSIDE the PCjr (take out the internal disk drive, unplug the 8088 processor, plug in the jrHOTSHOT, plug the 8088 into the jrHOTSHOT, replace the disk drive - actually not difficult, took me under 30 minutes, as I recall). It comes with 256K or 512K of additional memory and can have neither, one or both of two options - a real-time clock and a diskette controller. The diskette controller has a cable that then attaches to an external diskette drive (or two external drives, if you so desire). Prices range from $149 for a 256K board to $269 for 512K, clock and disk controller. I'm pleased with my purchase. I got the diskette controller, but have not yet attached a diskette drive. Everything else (512K and clock) works fine. Comes with a "60-day money-back 'full satisfaction' trial period" and 2 years' guarantee against material defects. Needs no ex- ternal power supply for the jrHOTSHOT; external diskette drive(s) would, of course, require their own power supply. I have no connection with ES Quality Products except as a satisfied customer. ------------------------------ Date: 29 December 86 09:49-PST From: JUNK%UVVM.BITNET@WISCVM.WISC.EDU Subject: PC-based emulation of Tektronix 4107 Graphics Terminal The rumour that I hear is that Tektronix(!) is about to announce both a software-based solution, and a hardware-based (single board) solution. ------------------------------ Date: Thu 1 Jan 87 00:58:29-EST From: John Romkey Subject: CodeView Interrupt Problem I ran into an interesting problem with Microsoft's CodeView, the symbolic source debugger that came with their 4.0 version of C. I thought a few people out there might be interested. I had a fragment of assembly code that was enabling an interrupt at the interrupt controller. It looked something like this: mov dx,[intc_port] in al,dx and al,[int_mask] out dx,al The idea was to read the current value of the interrupt controller's mask, mask another interrupt on, and write the value back out. While I was single stepping through the code with Codeview, I found that AL got loaded with 0xFF, which was absurd. All the interrupts were disabled! I tried doing an input from the interrupt controller mask register by hand, and got something like 0x89. Both before *and* after single stepping through the IN instruction. Finally, I put a breakpoint after the code and just ran through it and found that the IN instruction did get the right value. Alas. It looks to me that while single stepping over an instruction, CodeView disables all the interrupts at the interrupt controller. This problem caused a lot of confusion for a fair amount of time, as I was trying to find out why a particular piece of code broke when I converted to Microsoft C 4.0 (I figured out why later; something to do with an odd symbol declaration and the linker).

What happened to me was that the sensor was very sensitive, and the tape covering the notch had a small depression, enough to enable writing to the disk. -russ ------------------------------ Date: Wed, 24 Dec 86 8:30:18 GMT From: Keith Dale Subject: Genealogical Software Martyn, The program, Genealogy ON DISPLAY (v3.1), is available from the SIMTEL20 archives in pd:.

The Church of Jesus Christ of Latter-day Saints (LDS), which sponsors the largest private genealogical record collection in the world, also has a record keeping program for $35. It is called "Personal Ancestral File 2.0". At that price their objective is clearly to break even on distribution and to encourage genealogical research. Their license agreement specifically invites co-development (code is written in Microsoft C). The program prints pedigree charts back 99 generations, family group records, and optionally LDS temple ordinance information. It handles every combination and permutation of relationship imaginable. It is available for IBM and CP/M-80 (and maybe others). I use the IBM version. It is very fast, and seems very complete. I have about 1000 names into it, and have had no problems.

Segall) Subject: Xenix Help I'm having serious problems here trying to compile some C code on XENIX 2.0. The program(s) were originally written on a 4.2 bsd system without much regard for memory usage, so they turned out pretty large. When trying to move them over to XENIX, I had to figure out the correct compiler flags. The most obvious was to use the Large/Huge model; however, in this mode the compiler screams "Compiler error: Infinite spill" or some similar garbage, and dies out on me. After some chipping at the source, I was ready to try a Medium model compilation. The code compiled and linked fine, but when I tried to run the executable back came the message "Not enough core" and I was back at square one. I tried talking to the people at IBM, and they won't even aknowledge any problem. Their basic attitude seems to be: (1) We don't debug user code. (2) The message "Infinite spill" doesn't exist. (3) The "Not enough core" is produced by a perror(3) call (it isn't - not in my code anyhow; the first thing I do is an "fprintf(stderr, ...)"). How am I supposed to show them that this is not so _WITHOUT_ their looking at the source code is a mystery to me to this day! I am running on an AT with 1.5 Mb of memory and a 60 Mb Priam disk, if that is of any help. The executable file comes to about 105 Kb text + 30 Kb data. Thanks for your help, Robert. roseg@taurus.bitnet P.S. - An interesting note on the Priam disk: if you follow the XENIX installation instructions, you end up with 4 par- titions: The BITmap 1 sector Xenix 1 ~18000 sectors Xenix root + swap Xenix 2 ~50000 sectors Xenix /usr FREE ~30000 sectors Now I wanted to put DOS on the free partition - and surprise: the DOS fdisk doesn't recognize the partition at all! The solution: after you format the disk for XENIX, create a new file system on the extra partition (boot from the floppy, use Xenix fdisk to define the partition, and do an mkfs). Copy the /usr file system there, and tell Xenix about it. Finally, delete the middle partition, and use DOS fdisk to define it as a DOS partition. Install system normally on C:, and you're done. All you need now is to use fdisk in order to switch from DOS to Xenix.

The Apple drive heads are larger than an IBM drive, so the Apple drives can't read/write to the smaller tracks that the IBM format uses. Another thing is that the IBM is double sided, while the Apple is only Single. IBM has 9 sector-tracks, while the Apple has 16 sectors. Basically, it spells incompatibility. The only way you can write (maybe) IBM readable disks is to hook up an IBM drive to the Apple. You would need a special interface, which I believe are a little hard to find. But a friend of mine picked up a whole handful of them today at a "junk" store... >or which would run on an IBM PC and allow it to read and/or > write Apple-formatted disks? (I'm talking about software, not a > hardware card, for instance.) Well, no SOFTWARE could ever do what you want... You will definately have to get into some hardware modifications, or some special interface... (and probably software on top of that!)
