This script supports disabling and enabling the Software Data Protection for AT28C256 ROM chips. The cheaper chips available on Ebay and from Chinese sellers are pre-owned and may have SDP enabled, as ...

This is a simple circuit for programming the 28C16, 28C64, 28C256, and similar parallel EEPROMs using an Arduino. Since the Arduino doesn’t have enough pins to directly control all of the address, ...

Behold this ATtiny85 based EEPROM programmer. It seems like a roundabout way of doing things, but [Quinn Dunki] wanted to build to her specifications using tools she had on hand. What she came up with ...

Chameleon adaptive analog modules from Okika provide preprogrammed, ready-to-use analog functions in a compact 14×11-mm form ...

When we first looked at [Anders Nielsen’s] EEPROM programmer project, it was nice but needed some software and manual intervention and had some limitations on the parts you could program. But through ...

NOTE: For this lab you will need to remove the EPROM containing the original AIM 65 operating system and replace it with your own. Ensure that you keep this chip safe as it takes time to make ...
