This is more than a dongle but not as much as a pain, not mention there would be less stress if you used a keyboard or the serial port regularly.

This is scary to look at, but it's similar to the above but without the simple expensive board.

I'm still looking around for other dongle solutions. i'm not giving up yet.

is P! in that shot the connector that nobody can find or another interface?

if you don't need the ground shell on the serial port, an RJ-45 female makes a lot more sense to me than a DIN-9 female for the Newton port if it'll fit, you don't need FCC certification for bog's sake!

post a link to the spec and pinouts or the .PDF docs on the chip on that guy's card, the whole freakin board layout is there for the world to see!

the price looks right to me for his board if it gives you a SECOND serial port. i'd have just put in the hours flipping burgers to buy one of his when i was a kid.

maybe the pinouts on the connector in the Newt he's using will suggest a way of getting the signals off the original port on that connector, dunno. find the specs/pinouts on the port.

this looks like PLAYTIME!

P1 is for a slot that apple had left open for a internal modem that never took off. The connector that nobody can find is the interconnect piece, the part that plugs into the newton on the dongle. Apparently it's a proprietary interface that apple made and nobody else has in stock anymore.

As far as the rj-45 that would be great, but there is no software internally that supports it without NIE, newton internet enabler. You'd still have to start out with a serial connection to get the software to the newton. Unless you're thinking of some sort of localtalk/ethernet guts connecting to P1. (THAT COULD BE TOTALLY POSSIBLE!!!) Then what would happen is that the rj-45 port would be just a serial port allowing appletalk over ethernet internally!!!! hmmmm... I have a local talk box i can crack open. I'll shoot some shots when i get back from work.

I think the plug for P1 would be easy enough to find somewhere. I'll post something on the newton talk list about pinouts asap if i can't find it on the web.

BINGO! but the RJ-45 would only be a readily available, more robust connector for the newt's existing serial port. it would be tapped from that modem connector if the signals are available on the pins. it'd be very easy to fab a circuit board or adapter cable if you can get the right part to mate with the modem port.

i HATE those flimsy DIN-8 connectors, crap shack sells a DB-25 to RJ-45 adapter that might make a good basis for a homespun serial dongle atachment point, NOT a 10baseT adapter. (in this suggestion anyway! )

I see what you're saying about the rj-45 connector, just use the physical plug for this application. Hmmmm.... so what would happen, is make a similar board to the SER-001 but with a rj-45 female plug and also make a adapter for rj45 to serial. what if we used an rj-12 plug for a phone-net connection? Just a thought. The rj45 plug actually fits in the hole in the 2000 behind the door. It would be a tight fit, but functional. I wonder if that was intentional...

As far as that dude who took the pictures of his board, would we still have to see the bottom? and the newton community is pretty cool about keeping info out and open. I could see him offering a built one or just plans. i'm just guessing though.

this is starting to get out of my realm of knowledge. Unfortunately i don't know anything about electronics, or at least enough to make something without plans. I can look stuff up all day, but i don't know how to apply any of it.

good thought, the components from a phonenet connector might work as an internal adapter even jumpered to the chip as in ~coxy's suggestion, but i thought a generic serial port would be more useful, even with an unconventional connector.

http://www.mpja.com/product.asp?product=8777+TT
find a link to the connector on the newton side.

the bottom is in the shots too, nopro! but if you get the pinouts of the connector on the newton it probably won't matter. it looks like that might be a standard laptop cable or board interconnect.

. . . me either, just fake it!

ok, i posted on the newted community, i emailed paul guyot and the guy who did the mod of the second link i posted at the beginning, and emailed the newton talk list. All asking for info on that internal port. I read some of the newton tech journals but they didn't really talk much of the hardware, which doesn't surprise me. They probably want to keep that secret.

As long as i don't break my newton, i'll try anything.

what did ~coxy suggest? i seem to have missed it.

here's a picture of my opened newton 2000 . The ruler sucks, but gives an idea of exactly what we are dealing with.

http://homepage.mac.com/avavricek/PhotoAlbum7.html

ok, and here is a link of what i think is the right match, if now, then this place will definately have it. The mistake would be my fault. i don't know how much though.

was there a schematic of your newt in any of the docs?
i have a feeling that the newt's serial port signals are not going to be on that connector.

if you could take a shot from above that looked like the diagram in that second link it would help a lot because the appletalk transceiver chip marked in the diagram:
http://dev.newtontalk.net/~dpadilla/images/dongle_killer_sch.jpg
is the same as the one on the adapter that provides a second serial port as seen in this pic:
http://mrpcbman.tripod.com/images/SER-001B_front.JPG

see: http://www.linear.com/pdf/sn1323f.pdf

looks to me like the P1 connector is for the unbuffered i/o bus signals of the strongarm cpu and the modem circuitry would act just like the appletalk transceiver on the serial card. so my estimate right now (when i'm REALLY tired) would be that connector P1 is a no go.

then you should probably get a job to make the money to buy that serial adapter instead, it looks sweet and $42.50 with free shipping is a bargain compared to the work parts and risk if you ask me!
check out these warnings:

soldering jumper wires onto the IC in the procedure described as dangerous in the link above.

soldering to the PCB as in the link you found and said sounded scary is probably MUCH safer than soldering to the chip.

here are great info links from googling for "ltc1323cg":
http://guelph.unna.org/unna/apple/documentation/Inside%20Newton2000/Inside%20the%20Newton%20MP2K.txt

http://www.venus.dti.ne.jp/~yos/newton/newtonhacks.html

if you still want to try, you can find most of the signals for that modem connector on the last link. it looks like gobbledegook to me right now, but babelfish the other .jp site hits on the chip ID and look for other number variations for the same part and see where it leads.

I've got the dongle and a job, i was just trying to help people out that didn't have one. I'm thinking that this project might be way over my head. There is that dongle destroyer sitting right there.

Good job with the links, i didn't do very well this time around.

I just installed one in a friend's Newton last Friday. Works perfectly, and it's a pinch to install. No problems whatsoever. The build quality is superb.

Also, the same guy (PCBMan) is working on other projects for the internal port. There might be some nice goodies coming soon(ish).
