Dat klopt, in Apeldoorn. Overigens kun je dat niet altijd aan het adres
zien. Bij Digital Equipement Corporation had ik een Amerikaans .com adres
en bij Ericsson een Zweeds .se adres. Dat is soms best lastig. Ik dacht
even dat je een Amerikaan met nederlandse voorouders was, maar
"doornenburg" en "tiscali.nl" duide ook op Nederland.
Even reageren op je andere mail (Engels is uiteraard geen punt...):

Op APRS zijn ook enkele weerstations actief. PE1NAT in Noordholland is 24
uur per dag actief. Hier in Apeldoorn hebben we een home-made weerstation,
helaas zijn daar bij onweer een paar componenten kapot gegaan en is de boel
nog niet 100% gecalibreerd.
Ik ken Weatherlink verder niet, maar het is leuk dat je als
niet-zendamateur dankzij Internet mee kan doen met dit soort wereldwijde
weer experimenten.
Succes met je hobby. Met vriendelijke groet,
Henk.

640k RAM and a 186, 286 or even an 8088 will run APRSdos..

Before you slog away trying to reconstruct old DOS source code to run on
low end machines, you might want to consider:
a) CDROM drives cost the same as floppy drives (<$20), and you can put a
lot more on a CD-ROM (such as Knoppix, a "run on anything, run off CD-ROM
only" version of Linux)
a1) USB disk drives are also cheap, non-volatile, and fairly large. 256MB
is around $25 (on sale). I haven't tried to boot off one yet, but it might
work. Compact Flash is another choice, however, even though the media is
cheap (thanks to cameras), I don't know about the drive (socket you plug
the media into).
b) I'd venture to guess that Pentiums (1s, Pros, 2s) are more common as
junk PCs than 486's these days.
c) For a sitting in the corner, dedicated machine, you should really give
consideration to power consumption. Newer machines consume less power (and
they're less likely to need a new power supply in the first place.)
Along the lines of the last, there is a very interesting set of
Motherboards based on VIA chipsets. (VIA EDEN and VIA EPIA among others)
They are Intel/AMD compatible, very low power, and only 17x17 cm (3x3
inches) (mini-itx form factor) and have no fan. The processor is soldered
onto the board (reducing mfr cost) and is typically a VIA C3. I would think
you could probably get one of these, RAM, box, etc, with 12VDC power
supply, for <$200.
WalMart, if you want to patronize them, sells a fully functional PC for
$200. The PS fan is a bit noisy, though. Comes with Lindows, a Linux
version with a windows lookalike interface, etc. but you can boot anything
you want on the box, once it's sitting on the desk. Similar deals are
available all over the place.
Dell is selling servers for $399.
I guess the upshot is that I wouldn't spend a huge amount of time and money
trying to resurrect an old piece of software just to run on old computers,
which are on their last legs anyway. (That said, I confess I have several
286 and 486 machines out in the garage that get used occasionally)
I recognize that using the old 486 is a "zero capital" solution to getting
a station on the air, but, I think that you can do better. By now, junk
heaps have more powerful computers, and, considering that you're going to
be investing $100 in the radio, maybe investing $100 in the computer isn't
such a bad idea.
Certainly, if you were buying everything brand new, one of the Mini ITX
computers + a low end mobile rig is the way to go. Someone has a web page
up where they are putting together an APRS node using one of these, but the
URL escapes my memory.
(BTW, if you have a newer computer with the soundcard on the mobo, then you
don't need the TNC. Just a cable from soundcard to radio.)

I was just thinking of doing all that work up front. for them...
or rather probably making the distribution disk the same, but then adding
BUILD.BAT file that would build the bootable disk. But I dont know if a
modern PC will boot from a floppy. I just tried it on a windows 98 PC and
it wont boot from Floppy, but maybe I had a bad disk and need to try
again...
>Are you talking about an APRS DOS "lite" (Home ;-)version?
No, the full up one will fit.

that it contains any secrets, but I guess most of you cannot read it

Kind regards,

>>2) Removes lots of stuff not needed any more
>
>What stuff is not needed ?
Mostly the OPS-DIGI list and its overhead. Remember the OPS digi list
allows you to change your outgoing path on the fly with just a 2-key
shortcut to any of 15 different paths.
ALso it allowed you to set up percentages of the time to use any of the
paths.
Also it allowed you to send EACH message line via a specific
path by just putting /XY in the tocall and it would use the /XY
path for that message.
All of this was needed back in the old days when you could not
use a generic path beyond W,W. So you needed to use directed
paths for anything longer. These days with WIDEn-N and the new
paradigm that you shouldnet be useing long paths on RF anyway,
meanse I can get rid of all that code...
I doubt anyone really used that stuff anymore... I dont...
Bob
