This is the first prototype of the Micro/Elf expansion board. This board provides an 8-bit IDE/CF interfce, a Q/EF? (jumper selectable) serial port, a socket for SRAM/NVRAM/EPROM (jumper selectable), and an expanded version of the Micro/Elf expansion bus. This board is shown with a 32k NVRAM that i used when developing the BIOS for Elf/OS. This version of the prototype had quirky issues when writing CF cards and therefore was redesigned.
