Yes, I have the logic analyzer and several low band units. All I'm missing is time but I'll do my best to set one up for testing.

If anyone is willing to do an Xcat-2022 with a modern processor I'd be
willing to help with the firmware.? With Kicad and places like JCLPCB
it should be much easier now!
Maybe just a daughter board for an ESP32 module or a "Blue pill? ??
(Why an ESP32 ... because you can GET them!? Unlike lots of other
things.)
The Xcat raced the F8 processor to provide data, I don't know if the
same technique would be viable with an X9000, but it will be easy to
find out.? Does anyone with an X9000 have a logic analyzer then can
connect to the "code plug" chip?

Likewise the control head is programmed with a separate executable via this interface. The radio has socketed firmware in 32, 64, 128 , and 256 channel capability. The 128 being most stable. The control heads vary in capability with some having socketed EEPROM and 8K expansion.

However this would require an interface to emulate some analog control head circuitry, speaker? and mike connections, as well as provide a BT tranceiver for the SB9600 bus.
