I spent this week testing the FDD control card in simulation. The testing process has come with some challenges, especially because the FDD control card is meant to be controlled by the 6502 (which is not included in the test structure). Instead of using the 6502, I am carefully toggling the signals on the control card to emulate RWTS sequences and making sure the output of the control card follows as expected. There are a handful of output waveforms available online that can be used to check if the emulator is working properly.
Overall, this portion of the project is on track for our “Testing and Verification” weeks.
For next week, I hope to have the FDD control card fully tested and have some testing done on the other peripherals. I also would like to start writing the peripheral drivers.
