So then in theory, one could simply remove those two pins from the connector of an 800k drive and then be able to use either type of cable with that drive? That seems odd because I don't recall any missing/snipped wires or unoccupied connector holes in 800k drive cables. We should figure out...

SMD means that the component is soldered on the surface of the board, as opposed to having wires that go through the board and are soldered on the other side. SMD things are typically smaller and require more experience and more precise tools to replace. Capacitors do go bad with age, even if...

Is the USB hub in the display supposed to show up in System Profiler like the hub in a keyboard? That might shed some light. Also - could you test these ports for if they are getting 5 Volts like they should? One way to test this is by plugging some sort of device that charges off of a USB...

You know what would be even better is if sheepshaver would delve into the hard drive image or installer CD and automatically access the Mac OS ROM file before starting the Mac emulation.

Yes, it's always possible to find Mac ROMs on the internet, but these are not necessarily legal downloads. The advantage of the Mac OS ROM update is that it comes straight from Apple and can be downloaded legally. So what I'm wondering here is if a patch to the Mac OS ROM update download is...

Oh my god, I am really sorry I have mislead some people in this thread.

Obtaining the Mac OS ROM file requires an old Mac to run TomeViewer and extract it from the Mac OS ROM update installer. This is not readily available to everyone who would like to use Sheepshaver. Would it technically be legal to provide a patch that once applied to the compressed Mac OS ROM...

Would it be possible to emulate toolboxes on one end for the 68k app and then on the other end provide Mac OS X toolbox hooks that reflect and affect the state of the emulated toolboxes? The overhead seems pretty big, but maybe with a fast Mac it would be tolerable? Are the toolboxes so...

If this was simple, someone would have done it. This proves to me that there is a lot that I am not aware of concerning what all goes on between 68k apps and Mac OS Classic. I am wondering why, instead of a complete system emulator approach that boots Mac OS - a computer in a window, what...

It troubles me that the power light does not turn on when the logic board is removed, because I was under the strong impression that the power light turns on in this condition if the analog board is good. That would point to an analog board issue. Can anyone verify what happens when you plug...

Dastardly thoughts of heat guns and irons are entering my mind - maybe as a last resort.

I'm not totally straight on how RAM sticks work on a signal level. I understand that something has to go through and refresh the contents of RAM constantly. Is this process within the realm of a microcontroller's ability? Also, for this RAMmish ROM SIMM, can address and data connections be...

This gets me thinking about microcontroller vs. FPGA because talking in serial is good for microcontrollers and talking right away in parallel is good for FPGAs. I'm starting to wonder if we could get by with just a microcontroller. FPGAs are fairly complicated to program in my experience. I...

I am no longer convinced that the green light is supposed to turn on when you remove the logic board. I know that it does on 5500s, but we need to verify this for 5xx series Macs like the Mac TV. (The Mac TV is most equivalent to an LC 520)

There are of course intermediate options to improve the single buffer method as well, for example, having a multitude of flags for discrete chunks of memory, then updating just the chunks that have been flagged. I'm brainstorming here - not necessarily is any of this reasonable or within scope...

For non-volatile, there is probably no way to directly write to the Flash in real time, so it would need to be buffered or double buffered. If we can supply twice as much RAM on this SIMM as ROM, then that would give us space for a double buffer. When the SIMM first powers on, it would need to...

With this theoretical FPGA / RAM module on a ROM SIMM, would it be feasible to then make a volatile read/write ROM disk? How about Non-volatile? I'm not aware of how the 68k does a write operation to memory or if that signal is available in the ROM SIMM slot.

Very cool idea to use DD-WRT with a login for WEP, I hadn't thought of that and that sounds quite secure. You could, in theory, bridge this router wirelessly through WPA to your main router creating a secure wireless WEP to WPA bridge. Plug in power cord, stash it atop the fridge or wherever...

As long as you are using an FPGA, you could have 2 modes of operation. "loading ROM" mode and "ready" mode. In "loading ROM" mode, you can hard-code this sort of functionality: Reset vector: location 0x0000 0000 At Location 0x0000 0000: Load reset vector with location 0xXXXX XXXX (default...

One definite workaround is to write new software and release it under a free software license such as GPL. From what I understand, it is even perfectly legal to reverse engineer file formats which allows, for example, Open Office to legally read and write real Microsoft Office documents...
