Mini file host

But since it would not be emulating any Mac that ever existed, there definitely would be compatibility problems.

It would work except when it didn't, which is not very satisfactory. If I implemented this, it would mostly be as a stepping stone to emulating later Macs, which is the preferred solution.

After figuring out how to patch the ROM to support a different size screen, I investigated whether it would be possible to patch the ROM so that it could function elsewhere in the address space. The answer was no. The Macintosh System software, in particular the part that installs bug fixes for traps that otherwise would be implemented ROM, assumes and depends on the exact address of the ROM.

It would not be enough to patch the ROM, any System Software version that might be used would have to be patched as well. But there is a later software update that is supposed to make a Mac II bit clean I assume by providing replacements for many of the ROM routines. Unfortunately this doesn't work in Mini vMac yet, for unknown reasons. Maybe in the future. I've received a " report " that there was a third party upgrade for the original Mac that allowed it to support more than K of memory.

So presumably it is possible for Mini vMac to do the same. I have not investigated this yet. Mini vMac does not currently support networking.

All that software will work in Mini vMac, but there is no modem emulation. Mini vMac emulates the serial ports with nothing attached. But that is likely quite some way away. A real Macintosh has a small amount of memory that is preserved when the computer is turned off. This memory, the PRAM, is used to hold settings such as sound volume, start-up system drive, and printer connection. Very early versions of Mini vMac also did this, until one day Mini vMac stopped working for me.

I eventually realized that it was because the saved PRAM was corrupted. This was a problem on real Macs too. A possible future feature for the Mini vMac build system is to make this easier, by providing build options for the more useful PRAM settings. Run time options are more complex to implement than compile time options, and would make the program larger.

If implemented in a simple way, having to constantly check what machine is being emulated at run time would make the program slower. Another major concern is that preference files can get corrupted. Similar to the PRAM issue mentioned above. This is a very common problem with a lot of software.

Not having a preference file prevents this problem. I would prefer to continue trying to make it easier to use compile time options. Mini vMac is small enough that you can keep multiple copies of it, each customized to a different use. Porting to other operating systems is fun, and central to the goals of Mini vMac. However, it takes a while for me to learn enough about programming for an operating system as different as these to port Mini vMac, and relatively few people benefit, so that is not too high a priority for me.

On the other hand, if someone who is already familiar with an operating system would like to port Mini vMac to it, I'd be happy to assist, such as by answering questions about how Mini vMac works. Mini vMac is intended to be portable, has been ported a number of times already, and is relatively simple, so I think it should be relatively simple to learn enough about Mini vMac to be able to port it to a new operating system compared to me learning enough to program for a new operating system.

In theory, Mini vMac can be ported to anything vaguely resembling a computer, so long as it has enough storage. However, it would be very difficult to create such ports, and impractical in the extreme. Note that there are 2 Agents for Dameware. With this Configuration: End User will have to approve permission when connecting to the remote system. Enable or disable File Transfer option to the and from the remote system Note: These configuration settings will create a registry file that you can then use when connecting through Dameware, or you can roll out via 3 options at the bottom.

Select the Install Options Tab, select Configure. Select the Checkbox for "Permission Required" the checkbox "also when Locked" applies to the remote system state. Check Permission Required for these account types. Limit DameWare Techs to connect only at certain times.

Non-Administrators: Access Tab. Disconnect if at the Logon Desktop. Select Additional Settings Tab. Select the Include Configuration File, you can edit the. Using this address simply returns control to the local machine. This essentially blocks access to domains with an address of You can create an extensive hosts file to exert control over how your computer access hosts over the network. This is often required in corporate settings where internal networks are employed.

You can also leave the hosts file alone and let DNS handle locating and forwarding your network traffic. Since the absence of an entry for a designated domain in your hosts file does not preclude you reaching that site through a DNS lookup, you might be wondering why you would ever want to edit it. There are several reasons why editing your hosts file makes sense to improve your speed when connecting over the network. You may also encounter situations where the hosts file is not working as it was intended to and is causing connection failures or other issues with your network traffic.

Today, many users never access their hosts file and get along quite well using DNS servers to lookup IP addresses. While you may never need to edit your hosts file , having the ability to do so gives you control over how your computer interacts with the Internet.
