I had to run Lord Nightmare's code and get the latest sound files. Here they are:

I'm not sure on this, but you may have luck doing a wake-on-lan through a VPN connection. If you have a router running dd-wrt in the target location, it should at least be possible to talk to the router through VPN (which would be on all the time) and have it send a wake-on-lan.

I have not tried this but it seems to me that a • (option + 8 ) pushes items to the end of the alphabet and a ° (option + shift + 8 ) or a space pushes it to the beginning.
It might be worthwhile to disable everything but these two extensions using Extensions Manager, including disabling all...
Note that using a single transistor will invert the signal.
With N-Channel:
input -> output
0 -> high-impedance (open circuit)
1 -> 0
With P-Channel:
0 -> 1
1 -> high-impedance
To achieve all 3 states, you would need 2 separate signals whether you use transistors or a...
You can decode the address range 0xFAXXXXXX with 2 chips if you have a 7400 (quad 2-input NAND) and a 7432 (quad 2-input OR). This leaves one extra NAND gate.
We should quantify ROM vs. paged ROM vs. RAM vs. SCSI vs. NuBus speeds. If you can get the data there fast enough (i.e. parallel ROM like dougg3's current designs), ROM should be the fastest but by how much I'm not sure.
I just pulled out the datasheet for the Atmel AT90USB647:
So the port values in fact affect the pull-up resistors when in the input direction. I would recommend writing all 1s to the ports to activate the pull-ups when reading. This should return all 1s whenever polling the ports with no SIMM...
If information is available directly on the address/data bus, that is the fastest possible access. But it seems like there would be a lot of overhead when connecting this with serial flash memory, in at least these ways:
- Extracting/converting serial data to parallel
- More complicated...
8 MB is the limit of the ROM slot, after that you have to start adding clips for more address lines, if it can work that way. Each clip would double the max ROM if the memory controller allows this.
Max ROM SIMM = 8 MB * 2 ^ (# of clips)
We also talked about using some sort of large flash...
Well, to me if you're using old software, it's nice but not especially critical to have the latest version of the old software. We can probably get by if we track down combo updates, security updates, and java updates. Anything else, like Safari, iTunes, Airport stuff, etc. - we can just...
I know enough 68k to be dangerous, but not without strict reference to the instruction set and lots of head smashing upon the keyboard.
I want to chime in that the Mac Plus that I tested my HD-20 on is not known good, so there is a chance that the drive is still okay, or just a short or open or...
I don't know if a powered hub would fix that or not. I think that it would fix it if the +5V line was disconnected, though I'm not sure what would happen to the signal without a common ground if that got disconnected. Testing for power could at least give some useful clues.
