Story

 

Flash-based ROM IC-Card for TANDY WP-2

Supports writing directly from the WP-2 without a seperate programmer and programming adapter with a relatively simple and reversible even solderless mod to the WP-2.

See the github repo for full info and files:

https://github.com/bkw777/WP-2_IC-Card/

ROM image and software for writing the rom to the card:

The 3d-printed cover below assumes a 256K flash chip (39SF020A) so no bank switch, and no write-enable switch (use a solder-blob instead).  
If you want to fully populate with a 512k chip and both switches, then see the github for the openscad file to generate a version of the cover with cavities and sliders for the switches.
