Q: PowerBook 145B--Network Extension
Recently I was given a PowerBook 145B, and when trying to access the Sharing Setup or Users and Groups, I get the following message:
"This control panel can be used only when the Network Extension is present. To open this control, first put the Network Extension in the extensions folder and restart your Macintosh."
How do I do this?
Also, I cannot connect to the internet. I don't believe that there is an internal modem since the Mac was set for an external one, which I don't have. Are there any sources for telephone modems, either internal or external?
The Mac appears to be running OS 7.5, and I am not at all familiar with this OS.
Thanks in advance.

Hi again,
Depending upon the type of internal modem, you may or may not need additional software. For an Apple (Fax/Data) modem something like the Express Modem 1.5.5 here could be of interest. It may become necessary to open the computer in order to determine the card type.
The PowerBook 145B does not have USB (nor do the operating systems in question support USB). So, if you wish to use an external modem, do look for an old serial modem instead.
Combine the "on disk" and "available" values for the (formatted) total.
Probably not enough RAM (see also the technical specifications). It is per se possible to enable virtual memory in the Memory control panel (using space on the hard disk = slower).
Yes, providing that you are using a separate boot floppy, you could do this. The 7.5.3 download is a bit special, since the nineteen files (once the .bin has been decoded) have to be placed in one folder on the hard disk. These files (one .smi and eighteen .part) together constitute a large disk image. You mount the image by double-clicking on the first (.smi). The installer will be found in the mounted image.
In principle, you could use any Mac or PC with a floppy drive for the download, if the MacBinary (.bin) decoding is kept intact until the individual floppy-sized segments/files have been copied to the PB 145B hard disk. Use an appropriate early version of StuffIt Expander on the PowerBook for the decoding. Before you make any attempt to erase anything from the PB 145B, it may be a very good idea to save existing files like StuffIt Expander and the PC Exchange control panel onto a Mac-formatted floppy.
Network Access (here) can be used to make a startup floppy. You can create an actual sector-copied disk from the downloaded Network Access image via the present system on the PB 145B (use Disk Copy 4.2 for this).

It does look like I do have an internal modem after all, as there is a telephone connector on the back. It may just be that I don't know how to configure it. Or it may not be working.

I do have an Apple external USB modem, but I am not certain how I could use that.

The hard drive says 69.4 MB on disk. I don't know if that would be considered an 80 MB disk or not.
Combine the "on disk" and "available" values for the (formatted) total.
I get the impression the disk is pretty full, as sometimes when I try to open something, I get a message saying there isn't enough memory to do so.

You mentioned the 7.5.3 download. Ideally I would like to do something like an erase and install and remove all of the previous owner's stuff and have a fresh installation of the OS. Am I right to assume that this would be possible on OS 7.5? Also, would I need to use floppy discs to accomplish this?

Would I want to download the 7.5.3 system on my MBP and then put it on a floppy and then boot from the floppy?
