Sometimes you really want to use your legacy SoundBlaster instead of emulating it for classic games. While modern PCs don’t have ISA slots, [TheRasteri] is fixing this shortcoming with his dISAppointment board. (via Adafruit)
ISA was the standard card bus for PCs during the golden age of DOS gaming, and many of these games will still run on modern x86 hardware. Unfortunately, they run into hiccups with regards to sound since they were designed to specifically support ISA-based sound cards. [TheRasteri] found he could access the ISA bus lurking in modern computers through the Low Pin Count (LPC) bus which is exposed on the TPM port in many modern motherboards.
Testing the card with DOOM, he gets music and sound effects with no emulation required. Open Source files and a more detailed video are on the way, so stay tuned if you’re hankering for more ISA goodness on your modern rigs.
We’re no strangers to ISA here. We’ve covered the basics of the ISA bus as well as plugging ISA cards into USB and how you can emulate vintage ISA cards with a Raspberry Pi and FPGA.
