    Macintosh Portable: IT LIVES!

    I was the one Charles had said was having the same issue. I thought initially it had to be the controller, because in my case, it would type the correct character, THEN type an incorrect character. Example is 'u' and 'backspace'. It would type a U, then backspace it. I and enter do the same thing...if you hit an I, it'll type an I, then hit the return key. Now that I've thought about it, it's actually the microcontroller just scanning the rows and columns, and executing them in order, based on thier position and the rows/columns being scanned in order to find the key being hit. So, I took the key caps off of the offending keys and blew them out, i'm still having issues with the keypresses...issues persist. None of the keys themselves seem to behave "shorted" together, yet I do see continuity between keys where they aren't on the same row or column. the X/Y for U has continuity with the backspace key, even though they're on different rows and columns. Could the coupling caps go bad, causing this behavior?

    DIY Localtalk - Ethernet converter

    OK. Totally glazed past the part where chips are available that contains the SCC built in ---- *thats* where I wanna be. With the raspberry pi being way more powerful, shouldn't we consider doing this in software (which I'm much more familiar with). I wanted to get involved in a hardware project to teach myself hardware things though, so maybe I can start buying stuff

    Haven't given up on the BTW. If someone manages to have more spare time than I do feel free to run with this lol I still need to re-cap a bunch of stuff. At the moment I seem to lack time *and* money.

    DIY Localtalk - Ethernet converter

    Easily done with a raspberry pi. Convert the serial output to RS232, and have a service that listens to the serial pins on the r-pi and translates them to a virtual mac serial port. Done. Everything already exists at a software level --- netatalk for appletalk, the serial port driver for a real mac serial port, and of course linux on the r-pi. The only part needed is gluecode to convert the RS232 signals to a virtual localtalk port That part is easy --- question is....is it cheating (too easy?)

    I'm restarting work on this. There have been plenty of implementations of this already, and the protocol is seemingly simple to bitbang. In fact, most implementations of this are essetntially bitbanging at the right speeds to perform the magic things. There's an arduino with USB host capability that I'm in the process of acquiring. I've just moved and settled in and finally moved my computer stuff into its permanent home, so forgive me for taking so long on this. Essentially, there's an USB stack for the arduino that allows for controlling a keyboard and mouse. The other end would just bitbang everything to a ADB keyboard and mouse. I've already had limited success with speaking ADB via an arduino and there's plenty of reverse implementations of this on the internet. Everything will be opensourced, and should be possible via an arduino.

    ADB to USB adaptor

    wow major thread neglect here on my responses. I had thought about the switchbox, but I literally lack ADB keyboards. There's a arduino already out there that implements a USB host interface and will enumerate HID devices (it's all built in). Then there's a arduino "chip" that you program against for talking to the GPIO pins on the other side. That's what I'm after --- but right now i'm still in spring cleaning mode.

    By chance if you have any extra drive trays available please PM me. I have a G4 XServe project (liquid-cooling) that is waiting for drive trays.
  8. Just kind of stumbled on this thread...the modem-to-modem connection is definitely possible. There are two things you need to fix to enable this: First is line power -- all telephone lines provide a low amperage power to communicate/power phones/etc. this page describes the "line simulator" that is required to make this work. http://www.jagshouse.com/modem.html Second part is the modems themselves. There are several lines between a modem and serial line that need to be possibly manipulated. An example I can think of is the following: I had a laptop with a modem (running linux) that connected to the 56k modem on my dreamcast. There was a web browser disk that would allow you to dial up to a ISP and connect to it, and allow you to browse the web. The first part is the easiest --- the physical part. Hook em up together. Done. The second part is telling the OS on the "server" side that whenever the modem answers, it needs to provide IP services (PPP). Typically, in windows, this is provided via DUN listening on a serial port. Now, the last part is the oddest part and the one I dont 100% remember: Ordinarily, modems are connected via telephone switching stations, which take one active call, route it to where it needs to go, prefixing that "connection" with a telephone ring. The idea is to simulate that. You'd dial any number, setup PPP/DUN, and to connect the call, you'd connect the lines together. The modem would detect the carrier and the ringing noise on the line, put the modem off the hook (answering the call) and there ya go. You *may* have to configure the dialing end to "ignore dial tone before dialing" because there wont be a dial tone. But once the modem dials the number, it'll send out carriers and the "server" modem will be listening.

    The E Series is da bomb! It's my work laptop now, and it's awesome (except for running some uber-locked down ultra-secure non-admin image of Win7). If you enjoy warm a warm pepsi, with all of the scanning processes going in the background, your cold pepsi from the machine turns warm in about 15 minutes.

    DIY Localtalk - Ethernet converter

    The book has arrived --- and I'm selling off things to fund this personally. So I'll be starting on this most likely this weekend
  11. What about this guy? http://www.ebay.com/itm/Apple-Mac-ATi-Radeon-9250-128MB-PCI-VIDEO-Card-Model-109-A27531-00-Xserve-G5-/170971841204?pt=PCC_Video_TV_Cards&hash=item27ceb742b4 I've been watching this for quite some time now, and if it may work with CI/QE support, i'll go ahead and buy it.
  12. Yeah -- I got this machine for $100 so I really cant complain. It's a awesome machine, and it fits neatly under my computer desk with my other 1U equipment in my condo. mcdermd: If you happen to have more info on this --- that would be awesome. I'm not doing anything like video editing or gaming -- it's more for smoother OSX things, and getting hardware acceleration working for watching H.264 movies (not HD). Mostly, I use it for running X11 applications via X11Forwarding from my i7 xen machine or my laptop.

    DIY Localtalk - Ethernet converter

    I had considered the Propeller, and the issue is that memory accesses are *slow* on these, and each cog has a specific amount of memory its allowed to access. And the total amount of memory available per cog is slow. I know about arduinos, I built a robot based on a arduino, and I have a arduino in my toolbox. The parallax, being a multi-core processor, is designed from the ground up to be useful for parallel programming. I reallly wouldn't be taking full advantage of the multiple cores, because everything is completely sequential. LocalTalk packet recieved from serial->tear it apart->convert it to a ethernet packet->send out. and the reverse. If I did this with a prop, I could certainly have two or three cogs work on multiple serial packets (or ethernet packets coming from ethernet) it's not completely thread-safe, IE I could have a situation where packets could "process" in the wrong order and cause problems. Those are the reasons why I was leaning toward arduino. I think the propeller is neat ( and I do have a project that will totally take advantage of its unique and awesome power) but I'm not sure if it would be useful for this..

    Yeah The Dell D610-630 and the 810-830 are SUPERB machines. I got a few of them from a company that traded up. They really are excellent machines, and I used to have one at work and loved it. Honestly, as long as you take care of it (keep the dust out of the heatsink), a Compaq 8510p is also excellent and the screen has a super resolution. I also had one of those at work. What I use as my daily machine now is a not really expensive hp elitebook 8560p with a i7 in it. Honestly, as long as youtube isnt in your "normal daily" category, I would have been fine with something like a G3/G4 something. As a web developer though, I need something with a little more juice.
