So you want to dump a ROM, but don’t have a breadboard? Use a Teensy, some female-female jumpers and if you have one, a ZIF socket. The power and ground wires have been cut and three additional leads soldered to each one to provide hard-wired values for for Vpp, !PGM, !CS and !OE signals. To make wiring easier, prom.c maps the address lines sequentially down the left side of the Teensy, and the data lines sequentially down the right side. Up to 14 bits of address line are supported, allowing up to 16 KB PROMs to be dumped.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
