Jeff Keacher has just unveiled a new computer project he has been working on to get his 27 year old Macintosh Plus computer system online to surf the Internet for the very first time using a Raspberry Pi mini PC to help a little.
The Macintosh Plus computer is powered by a 8MHz CPU, 4MB of RAM, a 50MB hard drive and black-and-white screen offering an impressive resolution of just a 512 × 384 pixels. Those were the days.
Keacher equipped his 27 year old system with a copy of the MacWeb 2.0 Web browser, which hr retrieved from a long forgotten FTP site and connected it to a Raspberry Pi to emulate an old school dial-up modem. Even though a dial-up modem was not actually required. Keacher explains a little more:
“Getting the Mac physically hooked to the network was a bigger challenge. The Mac Plus didn’t have an Ethernet port, and things like WiFi were years from being invented when it was manufactured. A couple of companies made SCSI-to-Ethernet adapters about 15 years ago, but those were rare and expensive. I thought about the problem for a while, and it occurred to me that I could channel the early days again: I could use the serial port and PPP or SLIP to bridge to the outside world. Like dialup without the modem.
I set up my Raspberry Pi and ran some Cat-5 to it from the router. Using a level shifter and a variety of old adapters, I managed to get a serial cable working between the Pi and the Mac. That took care of the hardware.”
