I got an email from David Ko who forwarded these amazing images:
abandonware box running King's Quest 4. note the little box under the right speaker... Roland MT-32 baby!
took a long time to find all these sierra titles
mmmm vintage sierra
Near as I can tell, Mr. Ko has every Sierra On-Line game ever made in the original boxes, and a set of vintage computer systems to run them all on, too.
Impressive, to say the least. My hat's off to you, Mr. Ko.
