Works great. Check your CPU socket.
Be sure to check your machine to see if you need a CPU socket. My Z80 was soldered to the board so I had to de-solder that first then add a 40 pin socket. Only took an extra 15 minutes or so, but keep that in mind when ordering. Machine booted right up and works as advertised.
Also the addition of this board requires you to add some height between the CPU and sound board. After that, it will no longer slide into the metal cage inside the machine. I used Amazon: "Nylon Hex Spacer Standoffs" and built a wood box for this to slide into as a replacement.
