I just found a couple of replacements for the radio stack which match them all up.
The audio panel, whilst not quite as complex, has the virtue that it's clearly visible. Even on a decent 17" monitor, the buttons on the previous version needed magnifying glasses.
The autopilot doesn't include autothrottle (or the Mach hold setting!) which makes it more realistic in my view.
I'll be uploading this to Simviation.com ONLY later tonight. Hope you like it.
