Well I haven't gotten to the point where I actually decided what solution I'd actually use. Ideally, it would be a two arduino solution, where one would take care of building a complete "LocalTalk" packet, and SPI would be used to trigger an interrupt on the second arduino which would throw the...

I dont know how much help I can be, but I'd be glad to test it. I'm working on a couple of other hardware related projects and know my way around software well enough, and I *might* be able to help. I can solder and test for sure though

The other awesome thing about the Logic analyzer is that once I get through with this project and no longer need it anymore, or upgrade, I can reprogram the FPGA to start work on the Apple IIGS VGA card I've been wanting to work on :D

Yeah i'm going to go ahead and get the bus pirate or https://www.sparkfun.com/products/9857. I'm leaning toward the Open Logic sniffer because it has the ability to look at 16 channels. The Bus pirate is really neat though, cause it'll automatically figure out what its talking to on the fly...

Yeah I had just double-checked. Oh well --- I'll look for a MAX488 and a serial cable I guess. Out of all the mac stuff I have, I dont think I have a serial cable.

Oh okay so I still need a transciever --- I'll still need to buy a MAX488, or do some level shifting somehow. Once I get it to 5V levels, I should be able to view the bits...I'm assuming the MAX488 will be for output back to the bus

Is there any upper limit to the size of a frame? Because I'm not sure if I have enough ram in my 328P to store a entire frame in RAM? I'm going to have to do some research on interrupts. This is exactly the kind of project I need to teach myself low-level AVR things, and on the surface it seems...

Okay I wonder if I can forget the RS232 stuff because its worthless to me anyway in this project, and just write some code for the arduino to look at data coming in from the PWM pins -- I really could use a logic analyzer but the salae logic is like $199 which is a little out of my range right...

Wow! That frame chart will help immensely! :)

Yeah for that part I've already realized I'll need to buy a MAX488 or similiar. Yeah decoding the transmissions is something that was an obvious plan item (and a big one at that) but I hadn't gotten there. Gotta get PHY done first, then work backwards.

The phonenet adaptor takes those TX/RX pairs and combines them into a single TX/RX pair. It's rather a simple schematic to look at, yet it works perfectly. I think I'm going to see if wiring that port up RS232 fashion works -- if it does then I kinda know that this might work out. I'm just...

The hurdle I'm at now is the physical connection. I'm not sure if I can just wire the port up like RS232 (as on the Mac to internet via serial thread) or If I have to go RS422. I can buy the transceivers online, so thats not a problem, it just isn't fun waiting for parts.

I'll be doing this tomorrow to see if I can read anything out of the serial port

Inside Appletalk in hardback form has been purchased. I suppose at some point i'll need to buy/build a logic analyzer but for now more research is needed.

Problem with that is instead of a picture you get some garbage text like FULL PG PIC or something.... And the font for some reason is KILLING my eyes --

Eh -- it's on amazon for like $4. So i'll just buy it. I dont even know at this point which questions to ask so i'll just buy it. I really really really am on top of this project though lol

I found out that the data is encoded using some modulation to ensure the data is valid and that the Appletalk driver itself (in software) talks directly to the port, not via any other serial method. I was confused to find out that schematics for creating a DIY phonenet box didn't include...

Now I believe they're *compatible* but i'm not sure how compatible. Some say apple supported 232 right out of the port for modems, but I'm not totally sure if I do whatever is needed to make it look like a 232 port if i'd get appletalk traffic, and then other sites say it's a differential...

Thanks -- It's nice knowing I can give back to the vintage mac community. According to some, I might be able to make RS-422 work like RS-232 which would work nicely in my arduino, but I'm not sure its literally that easy. Anybody else have any ideas on that? Once I get that part worked out, the...

PLEASE PLEASE lemme know if you get this done and tell us how you did it. My SE/30 front panel is major borked and its cracked.
