Breadboard-less ROM dumping – using an Adafruit ZIF socket and F/F premium ribbon cables

7673323120

Breadboard-less ROM dumping » NYC Resistor. Uses our lovely ZIF sockets and F/F premium ribbon cables – the pull-apart rainbow colored ribbon makes it a lot easier to do this sort of project without getting an eye-ache!

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.


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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
