Double+ speed Osprey Co-Processor. Occupies one ISA/EISA PC slot. Writable control store, FPGA implementation of PDP-11 architecture with 4 MBytes of tightly coupled, zero wait-state memory. Includes FPJ11^® compatible hardware floating point. Performance equivalent twice the DCJ-11^® and 100%; of FPJ-11. On-card x86 microprocessor rapidly processes "virtual" I/O instructions. This card is used for Osprey/PC applications where all applicable I/O devices are emulated on the PC by Osprey software. Includes standard environment support for MS-DOS^® V6.2.2. Windows/NT^® environment support available.
