With this, I was able to download from an FTP server using Fetch:Īlthough the serial port speed is set to 19200bps, download speed is only 1.8KB/s or around 14.4Kbps. With PPPD running, click Open on the Config PPP panel and your PPP connection should be established. Refer to my previous article more more details on setting up PPPD. By configuring the above script to run in the background as soon as the Raspberry Pi starts up, the PI is now efficiently a minature PPP server. It will auto-start again after each connection session. This causes PPPD to keep running on the host machine and constantly looking for new connections.

Contrary to what I read on some other sites such as this, no level shifters are necessary, even for USB to serial adapters, as the RS-232 procotol should be tolerant enough to intepret the voltage levels of the RS-422 protocols used by the SE appropriately.
To test the connection, I used ZTerm on the SE, with a terminal software such as Putty or TeraTerm on my PC, configured both serial ports to se to the same configuration (baud rate, stop bit, partity bit and handshake settings), try to type on each of the terminals and make sure that you can see what you type on the other side. For this, I used the following pinout, found on : The two serial ports of a Macintosh are mini-Din-8 connectors labeled with a telephone (the “modem port”) and a printer (“printer port”) and an adapter or a custom-made cable is needed in order to connect it to the standard DB-9 or DB25 serial ports found on most PCs. The connection will be very slow but should be usable for simple tasks. But as I am not sure if my external dial-up modem would work with the Mac, my plan is to use a cross-over null modem cable to connect the Mac to my Raspberry Pi hosting a PPPD server, and use MacPPP and Config PPP on the SE for Internet access. However, without a hard-to-find SCSI to Ethernet module (such as the Asante EN/SC or the DaynaPORT SCSI/Link) or a PDS Ethernet Card designed for the SE (one made for the SE/30 won’t work), the only way is to use an external modem on the serial port and access the Internet via dial-up. With this in mind, I started to look for possible ways to connect this machine to the Internet.
My first wish is to be able to access the Internet, albeit in slow and primitive fashion, on this vintage machine. Obviously I do not expect to torrent or watch HD movies on it, but simple stuff like email, FTP, telnet, or even web browsing should be possible. The machine now works just fine on a 256MB SD card running as the SCSI hard drive and 4MB of memory: Using Amigakit’s SCSI2SD adapter, I was able to remove the dead 20MB SCSI hard drive and emulate it using a micro-SD card. Below is a photo of the machine, complete with keyboard and mouse, running MacWrite: The machine could not power on at first, but after cleaning up the motherboard, reseating all socketed chips, and replacing the RAM with using spare SIMM modules from my junk box, the machine managed to boot up just fine. Last week I found a vintage Macintosh SE that had long been hidden inside the store room of my apartment.
