"RBBS-PC" was written in compiled basic by Tom Mack, who distributes the program, essentially free, through the Capital PC user's group. The address is Capital PC User group Membership P. O. Box 3189 Gaithersburg, MD 20878 If you don't want to join the user's group (PD disks are cheaper for members), RBBS-PC can be obtained by sending a check for $8 to the Capital PC Software Exchange P.O. Box 6128 Silver Spring MD 20906. RBBS-PC is distributed on two double-sided, 9-sector, diskettes. Allow 3 to 4 weeks for delivery -- remember this is an all-volunteer effort. Be sure to specify RBBS-PC CPC14-1A on "diskette # 18". Include a label with your name and address. The exigencies of RBBS-PC software releases may mean that diskette 18 contains an earlier version of RBBS-PC than CPC14-1A (either you bought diskette 18 sometime ago or there has been not enough time for diskette 18 to be updated to this most current version). At least two bulletin boards keep the most current copies of RBBS-PC CPC14-1A for downloading. They are: (703) 759-5049 --+ +---- East Coast (Great Falls, Virginia), (703) 759-9659 --+ (415) 689-2090 ------- West Coast (Concord, California). I looked at Fido and decided against it because I didn't want to get involved in forwarding too many people's mail and problems of paying telephone bills. I looked at Colussus but when I implemented my BBS it had already dropped out of sight. RBBS-PC seems to be very well supported. its comes with the source code (all be it in basic!). It has all the features that I wanted, including the ability to have conferences and run programs remotely. There's also a fair amount of support software out there. Current RBBS version is 14.1A. It can be downloaded from my system. I have no commercial interest in any BBS program.

I think it has at least as strong a claim to be a "standard" as does Fido, if not stronger. RBBS-PC is, I think, much more user friendly than the Fidos that I have used. It does not, however, have the network mail feature for exchanging mail among many PCs. It does have conferences, multiple file directories, and multi-user support. Many utility programs have been written for it. The primary author is Tom Mack, but many people have contributed modifications. The latest version is 14.1A, but 14.1B will be out very soon. The major new feature in 14.1B is Kermit support. To address the reliability question, I have been running 14.1A, with Tom Mack's April 13 fix file applied, for 2-3 weeks now on a 5-user system and it has never crashed (so far -- it's bad luck to say things like this). RBBS-PC may be copied freely as long as it is not sold. The source code (in Microsoft QuickBasic) is included with the package. The latest version may be obtained for an $8 copying/mailing fee from Capital PC Software Library P.O. Box 6128 Silver Spring, MD 20906 There is also a very good commercial BBS package for the IBM PC called TCOMM. It is written in C and has a lot of nice features. It can be tried by calling 301-428-7931 at 2400, 1200, or 300 bps. A demonstration package is available for downloading there. Another good commercial package is PC-HOST. It is designed for businesses. It can be tried at 301-949-8848 if you are persistent enough to get past the busy signals. ------------------------------ Date: 22 May 1986 16:19:24 PDT Subject: Re: BBS Software From: Richard Gillmann To: Info-IBMPC@USC-ISIB.ARPA Here's a brief list of BBS software currently available.

To: info-ibmpc@USC-ISIB.ARPA The output voltages in the Zenith are different from IBM's color card (and other equivalents), thus the MAX-12 monitor is unable to detect whether it is connected to an IBM monochrome card or a color one. Princeton is willing to tell you how to change the Zenith video but this requires hardware modification and will thus void the Zenith guarantee. ------------------------------ Date: 21 May 1986 0924-EDT From: "Bernie AT&T:617-467-5664 DTN:297-5664 LDP Workstations" To: info-ibmpc@usc-isi cc: watson@akov04, abn.iscams@usc-isi, garrison@gold Subject: REFORMAT.ARC Rick Watson was nice enough, to 'test' REFORMAT on his 20MEG hard-disk - and 'slightly' enhanced same. 1. Looks like the 'standard' formatter uses 16bit FATS -- REFORMAT didn't handle that -- fixed 2. If re-ordering takes place on the 'logged in' disk , obviously DOS doesn't know about it - and shows a 'pretty damaged' disk.

Yes, PC VMS, as in VMS on a PC. While we were initially quite sceptical, and indeed did not REALLY expect the software to even show up, I must say that I am quite impressed. PCVMS is an operating system which can be used in place of MS-DOS. It is multi-user, allowing two additional users through outside ports, [supposing one would want to do that] and multi-tasking. Not only are the common VMS commands available, but many of the significant VMS system services are available as well including event flag support, ASTs, QIO, Logical name translation, and timers. The documentation is very good, given that one is already comfortable with VMS, it is NOT just retyped VMS documentation. As an aside, as good joints are to good woodworking...due to the process scheduling, the print spooler, called the print symbiont in VMS, is the smoothest I've ever seen, far superior to the standard print command. The printer just continues to chug along almost without interruption and the console process seems to barely be affected. The above is after using PC VMS for less than a week and without multiple users, but for $99.95 including source, you can't go wrong. The companies address is; Wendin Inc. Box 266 Cheney, WA. 99004 There is also a PC UNIX which appears to be very similar, we haven't put it up on our PC, so I'll say nothing.

To: info-ibmpc@usc-isib To kill the EGA cursor, use a routine like this one... mov cx,2000h ;turn on bit 5 of ch register -- cancels cursor mov ah,1 ;request ROM-BIOS function 1 int 10h ;ROM-BIOS video services interrupt int 20h ;DOS end-of-program This will generate a .com program about 12 bytes long, which will leave your cursor off until something else turns it back on. If you replace the 2000h with 0607h, you should get the regular 2-line underline cursor back. Note that this routine should work with any BIOS-compatible video board...EGA, color, or not. [Watch out when you turn the cursor back on, though -- 0607h gives a hyphen on the monochrome display, rather than an underscore. -rag] ------------------------------ Date: Wed 21 May 86 08:26:03-PDT From: David John Buerger Subject: Video Cards -- Everex To: fulton%comet.DEC@DECWRL.DEC.COM cc: info-ibmpc@USC-ISIB.ARPA I've been quite pleased with the Everex EDGE and the Everex GRAPHICS EDGE cards. We have installed quite a few on campus, with very few failures. I would probably recommend against buying the Hercules or Hercules compatible cards, mainly due to their limited use. The only software that will run on these cards is that having Hercules drivers. On the other hand, Everex cards (and the like) not only provide "Hercules" compatibility, but also may act as a straight color monitor. This will allow you to run anything with IBM color monitor drivers. The range of useable software is therefore much wider with this type of card. While most of these "Everex-type" cards are probably reliable, I've found Everex to contain more related features. Everex's phone number is (415) 498- 1111; they're located in Fremont, California. I have no relationship with Everex--just a satisfied user. David J.

The result is a few new, good, programs: Cache2.Arc Real small disk cacheing program with more smarts (described in the doc file). Give it a try. Ccompile.Arc Small-C compiler. I wasn't sure if this was available elsewhere on the net, so here it is. NewKey24.Arc NewKey v2.4 keyboard enhancer. I think this is the newest version. I haven't tried it yet, but soon... Mark&rel.Arc !!! Now this one is useful: run MARK in between loading resident programs (SideKick, Lightning, CED, et). When you want to remove them from memory, just run RELEASE and give it the name of the label you gave to MARK. RELEASE removes all resident programs AFTER the specified MARK (so no holes are left in memory). Here's an example batch file: AUTOEXEC.BAT: MARK SideKick SK (run sidekick) . . . LOTUS.BAT: RELEASE SideKick (frees that memory) LOTUS (run Lotus) MARK SideKick (when done, set a mark) SK (Load up sidekick again) I'm not sure these batch files actually work, but you get the idea. These are all available from [UTEXAS-20] via anonymous login. See the file FILES.DIR for information on the other files available.

To: fulton%comet.DEC @ decwrl.DEC.COM CC: info-ibmpc @ isib I do not have experience with the Zenith ZVM-1240 monochrome monitor. However, I have had experience Zenith ZM-135 RGB monitor. This monitor has a DB-25 on the rear of the machine. It can take inputs from Commodore, Apple, IBM, Zenith (obviously) and several other machines. The pins from the DB-25 are selected based on the type of machine that is doing the signal driving. The monitor is currently being used with an IBM compatible machine. I would imagine that you have the same type of options on the ZVM-1240. However, ... I am using an Everex Edge graphics adaptor. This can interface with either an IBM compatible monochrome or RGB monitor. The book says it can do the following: * Hi-res mono text/graphics, * is Hercules board compatible (quite true), * can select color mode for the adapter and mono mode for the monitor and thus run those programs designed for the CGA (also true), * uses mono character set when running in color mode with a mono adapter, * can display 132 cols in color/mono mode (mono mode good, color mode readable), * does four colors in CGA Hi-res mode (if the software will support this but appears to be true), * does Lotus/Symphony software without modification (also true) In short, I am pleased with it.

The result is that if you try to format another, the system hangs. Until we or someone else figures out the purpose to which this memory is put, and a safe way to relocate this buffer or whatever it is, the safest way to get around the problem is to re-run FORMAT for each disk you wish to format. In other words, always answer 'N' to the prompt. I hope no one got bit by this problem.

Granoff I have a bit of a problem...I am writing a window manager and naturally it is important to be able to read areas on the screen for later restoration. I have figured out how to read the characters that are on the screen but I can't seem to get the attributes. A good window manager should restore attributes when it closes a window! Here's the gist of my thinking: In TURBO Pascal, I am using the Mem[] array to address the screen (I have an AT&T PC 6300, so the address of the screen (Col 1,Row 1) is $B800). I determined that an offset of 160 bytes is the memory address of Col 1, Row 2. The Mem[] array is of type Byte, so if a character in memory consists of 2 bytes (1 for the character code and 1 for the attributes), then the byte at address $B800+$01 should be the attribute of the character in Col 1, Row 1. Right? (Or perhaps the bytes are reversed i.e. addr $B800 is the attribute and $B800+$01 is the character). Anyhow, I can't extract the attributes. I would prefer not to use interrupts (although I know it's relativley easy that way); reading from and assigning to the Mem[] array seems to be quite speedy. If anyone has any experience with reading/writing characters AND attributes to the screen, I would appreciate hearing from you. Thanks in advance. I will summarize any answers I get and post a summary on the net. Mark H. Granoff (mhg@mitre-bedford) ------------------------------ Date: Fri 23 May 1986 17:12:29 EDT From: Subject: Configuring a High-Powered Graphics System on a PC AT To: info-ibmpc@usc-isib I'd appreciate any help anyone could give me on configuring hardware & software for the following system: Several friends of mine are working on a grant which involves, among other things, putting 3D animation onto videotape on a low budget (i.e., well below VAX scale). The graphics board picked for this is one of the new AT&T TARGA boards, with 512x512x32 resolution. It's made to run on a PC/AT. This particular board was picked for its price/performance ratio, and the rest of the system has to be configured around it (so no 68000 machines, unfortunately). The rest of the video part of the hardware is pretty well worked out: they're getting Sony BVU-800 or 5800/50 decks (the 800 is supposed to be higher quality & more durable, but is more expensive -- anyone have any experience with either?), an EECO editor, and either a Lyon-Lamb animation controller or another one (whose name I forget) that fits on a board inside the PC. Now they need to pick the machine that runs the TARGA board. It must: 1) Be PC/AT compatible (enough to run the board correctly) 2) Run at at _least_ 8MHz 3) Have a floating point coprocessor (80287) 4) Have many megabytes of RAM (at least 2, 4 preferred, 8 great) 5) Have a hard disk of at least 80 MB 6) Communicate with a Mac+ (used as a front end) As you can see, the more souped-up the PC, the better, as long as it still runs the graphics board OK. The software requirements are as follows: Since MS-DOS has problems with addressing large amounts of memory in any kind of sane fashion, they plan to use UNIX(tm) or some other *IX. What experience have people had with various UNIX-like systems running on an AT (clone)? Will they (the systems, not the people ;-) recognize the hard disk/RAM/coprocessor additions above? Along with the OS, they need various tools like editors, compilers, etc. What compilers (Pascal/C/Modula2 family) are available for the *IX world? How compatible are _they_ with the hardware requirements above (esp. coprocessor & huge address space)? If they choose C, they'll need lint or somesuch (large project). Any other software recommendations? Please send responses (or questions) directly to me & I'll summarize them for everyone else if appropriate. Thanks for your time, whoever you are. -- Tom O'Brien arpa: obrien@LL ------------------------------ To: info-ibmpc@usc-isib.arpa Subject: Microsoft C and Environment Space Date: 23 May 86 19:11:47 PDT (Fri) From: Randy Has anyone noticed that Microsoft C fails to recognize expanded environment space? I have a compile command line that generates the error "argument list for p0.exe too big". The manual says "The combined length of all arguments on the command line (include the program name) may not exceed 128 bytes." Well my command line is well under 80 bytes. I called Microsoft to find out what the deal was. They said that my environment space was too big; if I undefined some environment variables things would work. (My guess is that the command line is passed a temporary environment variable between the passes of the compiler.) So I undefined some things, and it worked. Now for the kicker: I've defined an expanded environment space with the undocumented /e switch to the "command" command. In other words, I have a line like the following in config.sys: shell=c:\command.com /e:x where x is the environment size in paragraphs. This feature has been discussed in info-ibmpc before. BUT, MS C seems to ignore an expanded environment size, no matter how big x is. It seems to always check against a 128 byte environment. Have I made myself clear? Has anyone else run up against this problem, or is there something obvious I can do to fix things? I'm sort of desparate for a fix. Randy Day.

I don't know what its specification is. I hope somebody out there can tell me about it. The controller was WD1015-03 of Western Digital Corp. I found most controllers made by WDC were WD1002-WA2. Did I get a wrong controller ?

To: INFO-IBMPC@USC-ISIB.ARPA I have a program that uses the 8253 Timer chip to control the period of tones generated as part of music on a PC. The software is written to access the same timer that is used to drive the speaker, but uses it to measure elapsed time rather than to actually generate the signal driving the speaker. The speaker signal is generated by toggling the AND gate that lies between the 8253 and the speaker. I use this unusual approach so that I can control the "loudness" of the note by adjusting the duty cycle of the square wave, while relying on the timer to maintain a fixed period. My problem is that I've discovered that the XT and AT apparently use a different frequency clock signal to drive this timer, and as a consequence, the notes come out several octaves higher than on a standard PC or PC Jr. What was especially surprising is that I've found a very old PC (probably a 64K motherboard version) that also has a higher frequency clock driving the timer. Has anyone else run into this? I would have expected the timers in the various PC, PC Jr, XT, and AT models to be more compatible! At present, I think the only thing I can do is try to measure the clock speed by letting the timer count between 10 msec DOS ticks, and compensating for the variations in the software. Any other ideas would be appreciated!

The numbers I've heard are $140 for the basic system, $100 for the development tools, and $140 for nroff, troff, etc. Does anyone know anything about this port, or have any experience with it? If it's reasonable, and the prices for real, it's a good deal. ------------------------------ Date: Sat, 24 May 86 14:42:29 edt From: grebyn!karl@seismo.CSS.GOV (Karl A.
