VERSAdos is an operating system dating back to the early 1980s for use on the Motorola 68000 [1] development system called the EXORmacs which featured the VERSAbus and an array of option cards. They were typically connected to CDC Phoenix disk drives running one to four 14-inch platters. The EXORmacs was used to emulate a 680xx processor in-circuit, speeding development of 680xx based systems. It also hosted several compilers and assemblers.

Contents

VERSAdos and the EXORmacs were produced by Motorola's Microsystems Division.

Overview

VERSAdos was a real-time, multi-user operating system. It was the follow on product to the single user MDOS that ran the 6800 development system called the EXORciser.

Both systems features a harness with a CPU socket compatible connector.

A Modula 2 compiler was ported to VERSAdos. [2]

<span class="mw-page-title-main">Motorola 6800</span> 8-bit microprocessor

The 6800 is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year.

The Motorola 6809 ("sixty-eight-oh-nine") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes.

The 88000 is a RISC instruction set architecture developed by Motorola during the 1980s. The MC88100 arrived on the market in 1988, some two years after the competing SPARC and MIPS. Due to the late start and extensive delays releasing the second-generation MC88110, the m88k achieved very limited success outside of the MVME platform and embedded controller environments. When Motorola joined the AIM alliance in 1991 to develop the PowerPC, further development of the 88000 ended.

The Motorola 68000 series is a family of 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel's x86 microprocessors. They were best known as the processors used in the early Apple Macintosh, the Sharp X68000, the Commodore Amiga, the Sinclair QL, the Atari ST, the Sega Genesis, the Capcom System I (Arcade), the AT&T UNIX PC, the Tandy Model 16/16B/6000, the Sun Microsystems Sun-1, Sun-2 and Sun-3, the NeXT Computer, NeXTcube, NeXTstation, and NeXTcube Turbo, the Texas Instruments TI-89/TI-92 calculators, the Palm Pilot and the Space Shuttle. Although no modern desktop computers are based on processors in the 680x0 series, derivative processors are still widely used in embedded systems.

The Interactive Disassembler (IDA) is a disassembler for computer software which generates assembly language source code from machine-executable code. It supports a variety of executable formats for different processors and operating systems. It also can be used as a debugger for Windows PE, Mac OS X Mach-O, and Linux ELF executables. A decompiler plug-in for programs compiled with a C/C++ compiler is available at extra cost. The latest full version of IDA Pro is commercial, while a less capable version is available for download free of charge.

The System 9000 (S9000) is a family of microcomputers from IBM consisting of the System 9001, 9002, and 9003. The first member of the family, the System 9001 laboratory computer, was introduced in May 1982 as the IBM Instruments Computer System Model 9000. It was renamed to the System 9001 in 1984 when the System 9000 family name and the System 9002 multi-user general-purpose business computer was introduced. The last member of the family, the System 9003 industrial computer, was introduced in 1985. All members of the System 9000 family did not find much commercial success and the entire family was discontinued on 2 December 1986. The System 9000 was based around the Motorola 68000 microprocessor and the Motorola VERSAbus system bus. All members had the IBM CSOS real-time operating system (OS) stored on read-only memory; and the System 9002 could also run the multi-user Microsoft Xenix OS, which was suitable for business use and supported up to four users.

PL/8, is a dialect of PL/I developed by IBM Research in the 1970s by compiler group, under Martin Hopkins, within a major research program that led to the IBM RISC architecture. It was so-called because it was about 80% of PL/I. Written in PL/I and bootstrapped via the PL/I Optimizing compiler, it was an alternative to PL/S for system programming, compiling initially to an intermediate machine-independent language with symbolic registers and machine-like operations. It applied machine-independent program optimization techniques to this intermediate language to produce exceptionally good object code. The intermediate language was mapped by the back-end to the target machine's register architecture and instruction set. Back-ends were written for IBM 801, S/370, Motorola 68000, and POWER/PowerPC. A version was used on IBM mainframes as a development tool for software that was being designed for the IBM AS/400, as well as to write the "i370" internal code for the "Capitol" chipset used in the IBM 9377 processor and some ES/9370 models and the millicode for S/390 and z/Architecture processors.

<span class="mw-page-title-main">Dimension 68000</span> Microcomputer introduced by the Micro Craft Corporation in 1983

The Dimension 68000 is a microcomputer introduced by the Micro Craft Corporation in 1983 that sought to emulate the Apple II, the IBM PC, and various CP/M-centric computers through a family of coprocessor expansion cards and emulation software. The Dimension 68000 can also run as a standalone computer based on the Motorola 68000 from which it gets its namesake. The computer is mostly the brainchild of Mike Carpenter, a former executive of a scientific instrument manufacturer who incorporated Micro Craft in Dallas, Texas, to develop the Dimension 68000. It had a market lifespan of three years and received mixed, mostly positive, reception from the technology press. Criticism was leveled at the $6,250 price tag for the computer with the full deck of coprocessor cards, as well as the extent of the emulation power of those cards.
