Rather than use a microcontroller to run the relay, [glitch] wrote a simple Ruby script on his computer to turn the EPROM eraser on for the precise amount of time that is required to erase the ...

Turn on the EMP-20 Programmer (in back). There is a power light next to the ZIF socket (Zero Insertion Force) and the ZIF’s handle should be straight up. Set the "T" switch on the shelf next to the ...

Some earlier units were capable of programming both PROMs and EPROMs. See EPROM. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

To prevent slow erasure over a period of years from sunlight and fluorescent lights, the quartz window is covered with an opaque label during normal use. Selecting EPROM chips requires the selection ...

But there are simpler ways to generate patterns, including an old-fashioned EPROM, as [DrMattRegan] points out in a recent video. Generating video signals is an exercise in periodicity.
