205 architecture evolved into the ETA10 as the design team spun off into ETA Systems in September 1983. A final development was the Cyber 250, which was scheduled for release in 1987 priced at $20 million; it was later renamed the ETA30 after ETA Systems was absorbed back into CDC. CDC CYBER 205 Architecture: ECL/LSI logic 20 ns cycle time (or 50 Mhz) Up to 800 Mflops FP32 ans 400 Mflops FP64 1, 2, 4, 8 or 16 million 64-bit words with 25.6 or 51.2 Gigabits/second 8 I/O ports with up to 16 200 Mbits/second each Cyberplus or Advanced Flexible Processor (AFP) Each Cyberplus (aka Advanced Flexible Processor, AFP) is a 16-bit processor with optional 64-bit floating point capabilities and has 256 K or 512 K words of 64-bit memory. The AFP was the successor to the Flexible Processor (FP), whose design development started in 1972 under black-project circumstances targeted at processing radar and photo image data. The FP control unit had a hardware network for conditional microinstruction execution, with four mask registers and a condition-hold register; three bits in the microinstruction format select among nearly 50 conditions for determining execution, including result sign and overflow, I/O conditions, and loop control. At least 21 Cyberplus multiprocessor installations were operational in 1986. These parallel processing systems include from 1 to 256 Cyberplus processors providing 250 MFLOPS each, which are connected to an existing Cyber system via a direct memory interconnect architecture (MIA), this was available on NOS 2.2 for the Cyber 170/835, 845, 855 and 180/990 models. Physically, each Cyberplus processor unit was of typical mainframe module size, similar to the Cyber 180 systems, with the exact width dependent on whether the optional FPU was installed, and weighed approximately 1 tonne. Software that was bundled with the Cyberplus was System software FORTRAN cross compiler MICA (Machine Instruction Cross Assembler) Load File Builder Utility ECHOS (simulator) Debug facility Dump utility Dump analyzer utility Maintenance software Some sites using the Cyberplus were the University of Georgia and the Gesellschaft für Trendanalysen (GfTA) (Association for Trend Analyses) in Germany. A fully configured 256 processor Cyberplus system would have a theoretical performance of 64 GFLOPS, and weigh around 256 tonnes. A nine-unit system was reputedly capable of performing comparative analysis (including pre-processing convolutions) on 1 megapixel images at a rate of one image pair per second.
