    Supporting immediate mode for the BIT instruction is a nice addition to the 65816, but ... it only sets the Z flag, unlike all the other modes which set N and V as well?! What a kludge. 😬

    Been reorganising and partly rewriting the low level SD card SPI code for the W65C265SXB. Couldn&amp;#39;t get anything to work reliably. Weird noise on the MISO line, not the clean idle state, but still some kind of response to the initialisation sequence. Checking for dodgy jumper wire connections, trying out old revisions of the code, etc. Then finally realised that I had not turned on the power supply output to the SD card, so whatever it was doing was off whatever current it was leeching...

    Activating the 3D board preview in KiCad is by far the fastest way to log out of my workstation PC, currently. Display server dies instantly, no questions asked. Enjoyed the long stretch without problems like this, but I guess I will have to turn off the hardware accelleration again. 😐
