  1. You are indeed correct, I was thinking about the other one that appeared recently. My sincere apologies. Welcome!

    is this card anything special?

    Looks like a card that allows for an FPU and then acts as a horizontal riser, if I had to guess.
  3. Yeah, we have discussed it here, as far as I know.

    ID Mac Plus 030 upgrade card

    I never would have guessed there was an actual tool for that.
  5. Wow, that is so not something I would ever do...

    Suprise found in a Quadra 700

    The 601 was a good first step, like the first Pentiums. Not great, but good enough to get things rolling.
  7. From what I've read Newer Technologies was able to essentially drop in a 740 G3 in place of a 603e processor on one of their blackbird CPU daughterboards because they are apparently fully pin-compatible, However, by the time their 740 G3 prototypes were completed, the interfaces for the CPU daughterboards were no longer being produced, so the project was dead in the water. Also, apparently in Japan, a guy was able to take a Newer Technology NuPower 167 Mhz CPU daughtercard, pop off the 603e, drop a 740 G3 in its place, and it worked without any difficulty. From what I can tell, the PPC740L would be a drop-in replacement for the 603e. What do you guys think? Based on this datasheet: http://datasheets.chipdb.org/IBM/PowerPC/7xx/PowerPC-740-750.pdf Would creating a PPC740L G3 CPU Daughterboard For Blackbird Powerbooks using a Newer Technology NuPower 167 CPU daughtercard as a base work? What frequency do you think we could get it to work at? Also, do you think it would be need active cooling? I'm thinking yes. As such, do you think that would be difficult to implement given the space constraints in the blackbird?
  8. Yeah, putting stress, such as another card, on a non-recapped system is a good way to bring out weird bugs. It pushes beyond the very little capacity that the system has for functional operation.
  9. Very interesting. I'll have to look into those bridges some more... Have to try and find one that is willing to speak 68030 bus, or the only way to talk to the 68040 side of the bus is to somehow interface with the CPU daughterboard directly...

    Disk Images

    Yep, your file types are borked Give TChange a shot: ftp://ftp.apple.asimov.net/pub/apple_II/images/disk_utils/tchange_info.txt ftp://ftp.apple.asimov.net/pub/apple_II/images/disk_utils/tchange.bin

    Powerbook 540c won't startup

    Thank you. The info you have provided has been quite helpful for those of us who eventually will have to recap their power supplies as well. Damn things.

    transceiver networking

    I had noticed the switch as well, but I figured that was the very first thing he did after installation
  13. Yeah, unfortunately, since it works as a PCI bus, it seems as though it would be very difficult to back-port it to any of the Powerbooks that use the '030 bus style, since that is more or less NuBus type (No such thing as an '030 bus that can handle PCI, at least as far as I am aware)

    transceiver networking

    Yeah, they are uncommon in home networking these days since everything has built in diagnostics for troubleshooting. However, in your case, those aren't available, so that is your only choice for testing functionality on the local system

    transceiver networking

    It's something you can attach after the transceiver that will allow you to test the hardware in your machine to see if its functional. It will help give you a better idea of where the problem might be. It's a little Ethernet plug: It looks like an ethernet plug that has its cable chopped off, but its supposed to be just a blind end. The loopback plug will allow you to test your system hardware

    Farallon EtherMac Adapter

    If you are going to install Open Transport on anything System 7.1 or above, I would use this: http://macintoshgarden.org/apps/open-transport-13-gold-master 1.3 is the highest version that 68k machines can handle.

    transceiver networking

    Use a loopback to test the card and the transceiver. If that fails, you know you have a hardware problem with the card or the transceiver. (the chance that it is the transceiver is very low, they are very simple devices)
  18. I thought the StartUp Disk control panel had a default it automatically went to if there was no selection?
  19. 4W, that's it? That would be 50% of the maximum that the 740 puts out. Very nice. Software controlled clocking? Hmm. I'd have to read up about that and how Mac's work with those.
  20. Those are exactly the type of heat sinks I was considering. Looks like he FX's heat dissipation could be manageable. I had no idea the 2300 was so similar in architecture. I can completely see what you are talking about. It appears that our two projects do certainly intersect. Anything you learn can be applied to future plans for the BlackBird project, and vice-versa.

    128k keyboard deep cleaning

    Very nice! Reminds me of the "Like New" Model M keyboard I got on CrudBay. Like new my left testicle! I had to take the damn thing apart and scrub every inch of it to get the crud that has accumulated in every aspect of it over obvious years of use.

    transceiver networking

    I don't think that will work with the hardware he has. Despite the title of the listing, that is not AUI, it is AAUI. They are not mutually compatible. AAUI is a dense 14 pin D type connector: AUI is a standard size 15 pin DB-15 type connector:
  23. That's an interesting idea. I must admit, I am not terribly familiar with the 2300's setup. The 750FX was indeed what I was thinking for B1, it would be the least difficult of the most advanced chips to implement. I agree, you have some strong points here in favor of the CX/CXe. The thermal budget is one of the biggest challenges we have and >6.7W is within the realm of reasonable, with some modification we are looking at for the thermal management system.
