LGP-21

Collect ‘em all! Released in 1963, the LGP-21 was the last member of Librascope’s family of serial memory computers: Lower cost, a simplified user interface, and slower than the LGP-30. Designing an FPGA replica is meant to be a “practice run” for me – next, I hope to contribute to the restoration of two real LGP-21s at the technikum29 computer museum!
