I bought the OPL3LPT from Serda Shop: [[https://www.serdashop.com/OPL3LPT|OPL3LPT]]

It's an Adlib compatible add-on for PC parallel (printer) port.

To make it work, I had to:
  * Make a AT keyboard to USB Mini power cable adapter
  * Download latest oplutil: https://github.com/pdewacht/adlipt/releases

EMM386 was needed. To load it, I had to edit config.sys on my [[Toshiba T3200SXC]]:
  device=c:\windows\himem.sys
  device=c:\windows\emm386.exe noems
  
Then I could load ADLIPT
  cd oplutil
  adlipt.exe

And Lemmings was running fine with Adlib sound.
