D.R.C. is probably Digital Research Computers or Digital Research
Corp., Texas.
I list S-100 card manufacturers on this Web page:

...but I don't have a sound effects card manual for that brand.

I have several of the manuals for the DRC S-100 Sound Effects board. We
used to OEM them for use in our video game products. The board is IO-mapped
to any 4 contiguous ports, and uses two General Instruments AY-3-8910 sound
ICs. Along with the hardware manual came a hard copy of DRCs Sound Command
Language manual, and a copy of GI's AT-3-8910/8912 Programmable Sound
Generator Data Manual.
