Briggs > pbriggs@golden.ncw.net I'm running a Clover port on my BBS. This is on the Civil Air Patrol Digital Network. Our National Clover Network consists of 22 Clover equiped BBS, all operating on 7.920mHz. How well does it work? After using it for six months, I think it is one of the slickest things I've ever used. We pass traffic overnite that used to queue for days or weeks waiting for a good opening on the same channel. It works better than HF packet, AMTOR, PACTOR, and as far as I can see, better than G-TOR.

Hank "...MUCH software available for it..." but what about the difference between Quality and Quantity? Just how many word processors, terminal programs, spreadsheets, etc, is enough? Sometimes more choice means more choice among better products, but not in this case. The best PC/Windows software are ports from the Macintosh. I recommend you choose a Macintosh, I did 5 years ago and love it. Unless there is some reason you CAN NOT use a Macintosh, a Macintosh will never bother you about video drivers, video modes, mouse drivers, "real" mode, AUTOEXEC.BAT, CONFIG.SYS, Extended Memory vs. Expanded Memory, memory managers, HIDOS, IRQ conflicts, CD-ROM drivers & cards, sound cards, and the magical 640k limit. You would not want a Macintosh if there is one particular software package you need to/have to/want to run. One of the things I do at work is write software for embeded 68HC11 based systems, on this Macintosh. The editing and compiling environment on the Mac is the best that can be found anywhere. I use the same Mac to draw the embeded system's schematics, layout and autoroute PCB's, parts lists, documentation, everything except in-circuit emulation. The Nohau emulator is hosted on a PC, as is my EPROM programer. Additionally, (at least with the Powerbook 180) the accessory video port may drive either a second monitor, or a copy of the LCD. The difference is when you have a second monitor, both the LCD and monitor are running at the same time and your "desktop" is expanded to the sum of the 2. The mouse slides right off one onto the other. If you want to see a big drawing, just stretch it across both monitors, the Mac's operating system will take care of it, the application doesn't have to know. PC's can not begin to do this. Macs support up to 6 monitors at once. I'm using a 21" 24-bit monitor, a 19" 1-bit monitor, and a 14" 16-bit monitor on a Macintosh IIvx. No video drivers. No jumpers. No hassle. On the other hand, Unix is often chastised for being obscure, complex, and difficult to maintain while I've found Unix to be much easier to maintain than PC's, MS-DOS, and Windows. And a PC running Unix presents the worst of both worlds. Rarely does a Mac run Unix, but it can, and DOS also, at the same time. 73, David Kelly, N4HHE dkelly@nebula.tbe.com ------------------------------ Date: Wed, 24 Aug 1994 09:49:20 From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!boulder!csn!col.hp.com!sdd.hp.com!usc!howland.reston.ans.net!EU.net!ub4b!idefix.CS.kuleuven.ac.be!rc1.vub.ac.be!artipc2!dany@network.ucsd.edu Subject: How do I get IP address?

To: ham-digital@ucsd.edu Has anyone had any success using a Baycom type modem with the HP 100LX palmtop? Before I go out and mess with it, it would be good to know if it is possible or not. The Hamcom interface I built wouldn't work with the 100LX serial port, and so I am now skeptical and would like some reassurance before I invest in the parts to build an interface for Baycom.

To: ham-digital@ucsd.edu Just go buy a KPC-3 works good tastes great. Seriously I used to use a Baycom from Tigertronics. It is a memory hog and likes power. I don't think the added cube of the KPC-3 is enough to warrent the hassle of the Baycom. The KPC-3 runs forever on a lithium 9V battery. My mobile com program is a freeware item called pax. The only real advantage of the Baycom and associated software is the lower box which shows all packets received so you can sniff the call of a local BBS when in a new area. You can do this with 'passall' and 'trace' with other modems. Pacom also makes a pocket sized modem with a nicad internal however I have spent a great deal of time trying to get there stuff to work and am not yet impressed. Hope this helps.

The FCC takes a dim view of broadcasting in amateur freqs. Now don't get yourself all bent out of shape - and don't go grabbing your Part 97 and flaming me with quotes from the current regulations. I am just pointing out that while the broadcast model uses the frequency more efficently, the FCC may not like the hoards of HAMs using it without special permission. I personally could do without the FCC knocking on my door with a NAL. I suspect special arangements would need to be made similar to the ARRL's for broadcasting their code practice & such.
