The [Zon X-81](http://localhost/product/zon-x-81/) and the T/S 2068 both use the AY-3-8910 Programmable Sound Generator (PSG) and they both interface with the PSG by using the PSG registers, so any sound settings will be usable on both. I tried the SOUND command on Zesarux and it seemed to have some extra noises with it. I know that the Zon X-81 emulation on the sz81 emulator is good, so I thought I would start there.
