Ok, good to know that something is running on the Quapple. As a corrollary to my original question, do you have a guess as to why CUPL 4 won't compile...

Thanks for the explanation! I looked at the code briefly and it doesn't look too bad to implement what you suggest. I am not familiar with Python threading, but I...

With the chip straight out of the parts drawer, xiflash does not detect it (I was jumpered for e000h). I then wrote the image to it using my device programmer...

Another problem, perhaps related to the EEPROM. If I enable the secondary controller and write the setting, the floppy configuration splash no longer appears during boot! Had to reflash with...

Hi, Sergey. I'm guessing you're too busy to respond. Thanks anyway for your work on this device. Since the second FDC is working at the hardware level I can use...

Hi, Stephane. Ooof. I haven't looked at, or thought about, this code in 5 years or so. I'll need to refamiliarize myself with the SysEx signaling (i.e. reading my own...

Hi, Stephane. At the time I was working with the Katana (2016) Wireshark and USBpcap were not able to see both sides of the communication. I ended up using the...

Colin may have better suggestions, but I took a simple approach: There's an area of the Sysex address space that holds the current "live" panel settings. If you look at...
