【Toshiba】 TOSBAC Series 7/70

This was the first Japanese produced 32-bit industrial computer designed for large-scale real-time online applications, and it was announced by Toshiba in 1978. It was designed throughout for ease-of-use and expandability based on Toshiba's wealth of experience in the control field, due to Toshiba's previous TOSBAC-7000 Series and TOSBAC-40 Series, and the series had the following features, which were based on a 32-bit architecture:

(1)High-capacity, high-speed hardware which aimed to achieve powerful processing capability and high-speed response
 ・Main memory
Logical space: 16 megabytes (Address space 24 bits)
Maximum mountable: 1 megabyte
 ・Arithmetic speed
Basic addition/subtraction: 0.36 microsecond
DMA transfer: Max. 8 megabyte/sec
(2)Outstanding expandability
Peripheral equipments: Addressable up to 16x255 devices
Achieved a composite system coupling a maximum of 8 machines via shared memory.
(3)Enhanced system maintenance capability based on RAS (Reliability, Availability, Serviceability) design
a. Expanded use of LSI
b. Main memory ECC (error correction) and other detailed error detection
c. Designed for improved maintainability, with features like online maintenance and remote diagnosis

(4)Outstanding cost-performance due to a revolution in mounting technology, based on innovations such as large PC boards, mother boards and back panels
(5)High-level languages, and highly expandable/flexible real-time software
