The rules on the size of computer that could be legally shipped from the US, Europe or Japan to the People’s Republic of China were yesterday significantly eased, with the new limit set at a Processing Data Rate of 550m bits per second, which seems to imply a 32-bit RISC MIPS rating of about 17: the previous limit was 285M-bits-per-second, and the new rules mean that most DEC VAXes and most Unix workstations will now get through; personal computers with a 116Mbps data rate can now be exported there in bulk, where the limit was previously 15Mbps; the rules for the Comecon countries have also been eased, and machines rated at 78Mbps may now be exported to the Eastern Bloc where the previous limit was just 48Mbps.
