README

        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

![Teeprom render](PCB/out/Teeprom.jpg)

[Teeprom](http://tandy.wiki/Teeprom) is an EEPROM module for Tandy Model 100, 102, & 200 portable computers.

# Meeprom

![Meeprom render](PCB/out/Meeprom.jpg)

[Meeprom](http://tandy.wiki/Meeprom) is an EEPROM module for any other Molex 78805 socket that expects a 27C256 or standard mask rom chip. Not for Model 100/200. Examples: Tandy Model 600, Kyotronic KC-85, Epson PX-4, PX-8, handheld terminals like Intermec 9440, various industrial equipment like Allen Bradley SLC-500 PLCs, etc.
