Comment (by athrxx):

 So, I have checked which SCI 1 game driver disassembly I actually used
 when I updated the drivers. And it actually is based on KQ5. The PCJr
 variant has been derived from {{{tandy3v.drv}}}. The PC Speaker version is
 from {{{std.drv}}} (and it is identical to the SCI 0
 variant, anyway).

 I see that KQ5 also has another sound driver: {{{tandy.drv}}}. We do not
 have anything based on that. I would assume that it is just another single
 voice driver, probably similar or identical to PC Speaker, for the Tandy
 hardware. But I haven't checked. I have just taken a quick look at the
 file to see whether it is a sound or a graphics driver...
