how is Research Machines 380Z and Amstrad PCW connected?
Research Machines 380Z The Research Machines 380Z (often called the RML 380Z or RM 380Z) was an early 8-bit microcomputer produced by Research Machines in Oxford, England, from 1977 to 1985.
IBM System 9000 The IBM System 9000 Instrument Controller (aka CS9000 or S9000) was an IBM workstation that was announced in 1982 for use as a laboratory computer. It was based on the Motorola 68000, running at 8 MHz and was one of the few systems that used Motorola's Versabus. Input/output ports included three RS-232 serial ports, an IEEE-488 instrument port plus analog and parallel I/O. It ran a custom operating system called CSOS, standing for Computer System Operating System. IBM also offered XENIX on the S9000, but this required at least 640 KB of RAM. The machines shipped with 128 KB RAM as standard, and this was expandable up to 5.2 MB in 256 K increments.
