Teeprom
About the Teeprom PCB
Teeprom is an open source PCB design by bkw777, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 38 × 16.6 mm, with 3 components from 3 distinct parts.
Other key parts include the AT28C256-15SU. By type, the board carries 1 IC, 1 capacitor and 1 resistor.
From the project
These are all virtual UV EPROMS / virtual mask roms, using electrically programmable EEPROM, FRAM, or FLASH with the pinout adapted to work in place of 27Cxx UV/OTP EPROMS or standard mask roms, on a specially shaped PCB and 3d-printed carrier to create a virtual Molex 78802 modu
These are all virtual UV EPROMS / virtual mask roms, using electrically programmable EEPROM, FRAM, or FLASH with the pinout adapted to work in place of 27Cxx UV/OTP EPROMS or standard mask roms, on a specially shaped PCB and 3d-printed carrier to create a virtual Molex 78802 module to fit inside a Molex 78805 socket.
Teeprom is an EEPROM module for Tandy Model 100, 102, & 200 portable computers.
