Getting the Mac physically hooked to the network was a bigger challenge. The Mac Plus didn’t have an Ethernet port, and things like Wi-Fi 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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
