Subject: KPC-3 Hacking
From: Miller Scott Contr 30SCS/FTI <Scott.Miller@vandenberg.af.mil>

X-Message-Number: 48
Following up on what I mentioned earlier... this is kind of a low priority
right now, but I want to be able to write custom code for my KPC-3.
Obviously, a lot of low-level code is going to have to be written from
scratch (I'm not even going to look at the Kantronics code), so I'm thinking
it might as well be released to the community so others can build on it. Or
laugh at my rusty embedded programming skills, or whatever. What are the
chances that Kantronics is going to have a fit about third-party firmware?
Legally, you'd think they wouldn't be able to do anything besides maybe say
it voids the warranty. But laws like the DMCA seem to give corporations
some pretty broad powers these days.
Thoughts, anyone?
If anyone's interested, here's what I've figured out from the schematic...
Memory Map
0000-7FFF RAM (Bank-switched on P60-63, up to 16 banks)
8000-FFFF ROM (Bank-switched on P64, 2 banks)
(DS1215 Phantom RTC shares RAM address space, if present)
Port Usage
P20 RXD from 3105
P21 TXD from 3105
P22 CTS (Port 2)
P23 TXD (Port 2)
P24 RXD (Port 2)
P25 CON LED, DCD
P26 PTT
P27 LED Master
P50 CD from 3105 (Inverted)
P51 XCD (Port 1)
P52-54 Unused
P55 Aux power detect
P56 RTS (Port 2)
P57 Unused
P60-63 RAM Bank Select
P64 ROM Bank Select
P65 RX LED
P66 STA LED
P67 Mail LED
All LEDs are active low
Port P55 is kind of weird... it's low if J7 is set when you're running off
power from either DB connector. Otherwise it's connected to the power input
pin of whichever connector you've selected with J6. On a normal RS-232
connector this should be grounded, so it'd show up low when something's
plugged in. Not sure exactly what this is used for.

Near zero. You have to buy their TNC to use it.

I can't imagine that they have anything to say about it.
They have rights to the fw in the existing rom of course, but that's where
it ends.
Take out the rom, and it's just a pile of parts.
I don't have ANY spare time at the moment, but I am interested.

Be careful here. They changed processors between the KPC-3 and the
KPC-3+, right? I think they us a 68HC11 now. I know where to get
free compilers for the HC11.
Don't bother with the 6303 stuff. You can't buy those TNC's new
anymore. The quantity on the used market is bound to go down quickly
as they age.

I went to site of Tiger maps, only to find them NUMBERED in a fashion I
have no idea which is for my geographical area. Did I miss something?, is
this (Tiger maps) a bit OVERKILL for a STATIONARY APRS station?
(Is this TRIP really NESSARY?)

The files winaprs uses are a bit trickier to find than other formats but
Tiger maps are not "overkill"
Tiger maps are an excellent alternative to what has been available in the
past. If someone had not already made detailed maps for an area one might
want then they would be forced to purchase extra software to get anything
better than a state or county outline.
I was lucky to find some maps for my region that someone had made into
winaprs ".map" files but there are no such maps for the area I'm about to
move to so now using tiger map data I can go download the data files I need
for that area to have street level maps without resorting to purchasing
precision mapping etc.
Tiger maps compatability is what first drew me to Xastir because at the
time Winaprs had very limited tiger mapping compared to the data xastir can
use. After testing out how Winaprs is using tiger data I'm not super
impressed especially after using Xastir.
For me... Tiger is very much worth the "trip"

In a message, the author asked about the numbering of the tiger maps and
wondering how to know which is for the area he is in. I would also
appreciate knowing the answer. Is there an index? As I travel all over the
country in my RV, I am also interested in knowing if I need to download all
of the maps that I saw?

The "B" implies a much faster part. At least, with Motorola parts.

Tiger map files are identified by FIPS code.
The list of counties and their FIPS code can be found here.

Anyone have the documentation or a Kantronics KAM all mode TNC, or know of a
web site to get it?
I need the Installation and Commands books. Electronic format would be just
fine.

Hi there,
If you've always wondered about APRS on the Cybikos and you'll be at
Dayton, then make sure you stop by at the West Mountain Radio booth.
Some friendly folks there (Robert, WP4YJ and Ned, KA1CVV) will be using
their Cybikos for APRS.

H all,
What hurts with all this talk about Tiger maps, amount of memory, speed of
computer and disk space, is the fact that SO many of us already invested in
the Precision Mapping software to run with Waprs261, only to have a map
that only fills two thirds of the screen, the other third just goes wasted.
Now, to browse the States with Tiger maps, you need to download 500
gigabytes of files, install only the area you are concerned with, unload
it, and go thru that process for another area because no way will the
computer load the states as we did with Precision Mapping and not crash..
This is of course, only my opinion, but I think this is a tremendous step
back for all the aprs users that stuck with a good program, but could have
be better.
I mean no disrespect to the Sprouls, and appreciate all they have done. But
to say they can't fix Precision Mapping is a problem.
Now, go down to the street level of the Tiger maps, and when all of the
street names are on the map, I defy you to pick out which street you are
actually looking at in any kind of reasonable amount of time because all
the street names run horizontal, regardless of the direction the streets
run!
My 2 cents worth,
Robbie, wa9inf
