  1. Hi all, I picked up a 240 MHz G3 card for my 6100, which fits the AVcard with some kind of adapter. I got the whole working 6100 along with it for 10 euro's. I am only looking for a new fan to fix the one that is broken in the power unit... Jelly

    Strange board on Mac 512k

    I will make new pictures, with more detail of the chips you mention. If I connect the board to the 512, I get a bong and a black screen. No effort is made by the Mac to start from a floppy. Since I have not found the time to try to make a good startup floppy, I have not seen the Mac boot completely. However, without the alien board, the Mac gives the blinking disc icon and you can hear it scan the (faulty) floppy. Jelle

    Strange board on Mac 512k

    Hi Osgeld, Nope, the images are still here: http://img638.imageshack.us/g/img8261r.jpg/ I thought a few days ago: let's ask my dummie-question at the liberation forum, they will be able to explain to me in simple enlish what it is I found on my 512k... but your inputs are close to abracadabra to me with abbreviations like TTL, IIRC and so on. But don't mind my 'noob-ism', I will ask a new explanation once you guys agree on the case first. Keep the discussion alive. I have never started a discussion anywhere that made it to a second page Someone said earlier that the power cable was strangely connected to the board, and later another guy said that it was nothing more, nothing less than the usual power/data cable for a Mac 512 logic board, but now necessary to connect the alien board. That is correct. For my own convenience I connected the two connectors on the board, for communication I had better not done so. About the NTSC/PAL discussion: it is and is not off topic. I was my fault in fact, by commenting on the matter that I started this bragging about 'another ancient technology' and I must admit, that in the time I worked with some PALevangelists, they always picked on the USA with lousy NTSC quality, complaining that they were not compatible and so on. My judgement was coloured without me knowing all the ins and outs. Since we all have fancy plasma these days, HD is the way to go... Next I must compliment all of you for using beautiful english styles, pointy and sharp but always with respect and the right tone. My native language in dutch but I always try to make an effort in using proper english. I got to learn some new thing here already. Another reason (next to the techie side) for me to visit this forum every now and then. Having all this said, please call on me if there is anything in detail you need to identify this board. Please do not ask me to connect it to the 512 because I can't get it running, I do not have an external monitor to test it and all the audio equipment I have here is a Mac for downloading and an iPod for playing music.

    The Price of an SE/30 in 1990?

    Funny how divers people are thinking about Apples development through the years. My first Mac was a Colour Classic with external Power CD (2499 and 699 dutch guilders new @ Correct in some sale) and from that moment things only got better. There was no Jobs at Apple, I believe Sculley was also gone and there were new models coming every now and then to suburban Holland. My country was, for Apple, in those days, a part of Apple Scandinavia, with very low focus. It changed later on by the way and Holland (Benelux) is a tier 1 country now, which means dutch is always in the first tier for software localization. My second Mac was a 5500 black mac, zillion times bigger/faster, still not very expandable, and that is exactly what somebody before me wrote here: I had the money and expansion sounded complicated and expensive, buying a new one is only expensive, not complicated and fun! After the 5500 I bought the first iMac 233. Also no expansion, also expensive and also a loads of fun. Buying new Macs has always been fun for me, like I even like to buy old Macs now for fun. Apple = emotion, an old manager once told me, and that emotion is positive for most people. Jelle

    Why are newton developers such greedy pigs?

    I did the eMate-wireless trick from geektechnique and it works! Dead thread or not, suckers like myself keep reading them every now and then. Jelle

    Strange board on Mac 512k

    I will make new, more and better pictures this weekend. Your speculations make me curious too. Even though I have always been wondering what the advantages of NTSC were/are, next to the existence of PAL (or even SECAM) it does sound eligible that the board has got something to do with a second monitor for this Mac. Checking the markings on the various chips on the board leaves me helpless on either a chinese website I can't read or stuck in a very technical environment: I am not a techie... Hope you guys will check my next posting also. Thanks. Jelle

    Strange board on Mac 512k

    Hi all, Thanks for your replies. Here a URL with a picture, hope it works: http://img43.imageshack.us/img43/3598/img0659j.jpg or http://yfrog.com/17img0659jj What program should I use on the SE30 to format an 800k floppy to 400k MFS? Or burn a system 2.0 image to an 800k floppy... This is such old technology, I lost all my knowledge over the years and the internet just seems to think I recall all the necessary steps... Thanks all, Jelle

    Strange board on Mac 512k

    Hi, Yesterday I picked up my first 512k. They are hard to get in Europe so I had to pay a whopping 20 euro for it But, on boot no glory. I opened it up and after scanning the molded autographs (yes!) of the creators, I picked up a service source manual to see what was going on inside. But my 512 k did not only have a logic board on the bottom and another board on the right, but also one on the left. No serials, no inscriptions, just IC's and some connectors. The connector from the standing board on the right was disconnected from the logic board and connected to the alien board and from there reconnected to the logic board. From the alien board 2 other connectors could be found: something that looks like the mouse-connector from this Mac (also the modem/printer connector) and one connected with two small pins to a cable guided outside the Mac with on the end 2 audio-like plugs, like the ones you find on your old record player. I can't post pictures here, but if you want a picture, please notify me. Disconnecting this board resulted in a booting Mac, but now I need to make a boot floppy. How does that work since I only have 800k floppies? I checked the floppy-drive inside and it is definitely a 400k model. My SE/30 only seems to initialize floppies to 1,4MB (?), also really odd in system 6 is my guess... Kind regards, Jelle
