The Tarbell Double Density Floppy Disk Controller was a S-100 bus peripheral card manufactured by Tarbell Electronics in the late 1970s.
It interfaced with the Western Digital FD1791/1793 floppy disk controller chip and supported both single and double density formats (FM and MFM encoding).
This emulator features a real Intel 8086 CPU emulation implementing the full instruction set architecture including all ModR/M addressing modes, segment registers, flag computation, ALU operations, string instructions, and more.
The 8086 was Intel's 16-bit processor released in 1978, featuring a 20-bit address bus (1MB), 14 registers, and complex instruction set computing (CISC) architecture.
This emulator parses ImageDisk (.IMD) format files and loads them into the 8086's memory space for execution.
