Building a Beavis Ultrasound ISA PnP Clone: From InterWave to EEPROM
Build an ISA Plug and Play clone inspired by the Gravis UltraSound PnP using the InterWave AM78C201, an IW78C21M1 1MB sample ROM, a 93C66 EEPROM for PnP configuration, and a GAL as glue logic. Learn why EEPROM byte/bit order matters and how the design’s structure helps debugging.
