HP 64783A/B Emulators for Motorola 68040, 68EC040, and 68LC040 Processors HP 64783A/B Emulators for Motorola 68040, 68EC040, and 68LC040 Processors Technical Data Design, debug, and integrate real-time embedded systems Description The HP 64783A/B active probe emulators support Motorola 68040 microprocessors from 16.7 to 40 MHz operation. These emulators offer the measurement capabilities that include interpreted displays of on-chip registers, nonintrusive display of emulation memory, deep trace analyzer, and hardware break events. In addition, hardware assisted software breakpoints allow setting of breakpoints in target ROM space to simplify the debugging of ROM. Foreground and background monitors are included to make it easier to accommodate various targets.

  • From 128K to Quadra: Model by Model
    Chapter 12 From 128K to Quadra: Model by Model IN THIS CHAPTER: I What the specs mean I The specs for every Mac model ever made I Secrets of the pre-PowerPC Mac models I Just how much your Mac has devalued Yes, we’ve already been told that we’re nuts to attempt the next two chapters of this book. Since 1984, Apple has created more than 140 different Mac models — including 35 different PowerBooks and 53 different Performas! Each year, Apple piles on another dozen or so new models. By the time you finish reading this page, another Performa model probably will have been born. So, writing a couple of chapters that are supposed to describe every model is an exercise in futility. But we’re going to attempt it anyway, taking the models one by one and tracking their speeds, specs, and life cycles. This chapter will cover all the Apple Macs — both desktop and portable models — from the birth of the original Macintosh 128K to the release of the PowerBook 190, the last Mac ever made that was based on Motorola’s 68000-series processor chip. When you’re finished reading this chapter, you will be one of the few people on Earth who actually knows the difference between a Performa 550, 560, 575, 577, 578, 580, and 588. 375 376 Part II: Secrets of the Machine Chapter 13 will cover every Power Mac — or, more accurately, every PowerPC-based machine (those with four-digit model numbers) — from the first ones released in 1994 to the models released just minutes before this book was printed.

  • Lessons from Discarded Computer Architectures
    Lessons from Discarded Computer Architectures Andrew E. Fluck University of Tasmania Locked Bag 1307, Launceston, Tasmania, 7250, Australia [email protected] Abstract. The BBC microcomputer was one of several nationally produced which were superseded by the International Business Machines (IBM) Personal Computer (PC). This reflected the results of both an international market com- petition and rivalry between different US processor manufacturers. Along with the hardware, valuable software and supporting educational ideologies were discarded. As we make choices about technological innovation, to what degree are we selecting potential efficacy or responding to marketing hype? Keywords: BBC microcomputer, IBM Personal Computer, Apple II, computer hardware, operating systems. 1 Introduction The BBC microcomputer was an 8-bit machine based on the Motorola 6502 proces- sor. It made a huge impact in British schools, putting predecessors into the shade of its colour graphics. Its successor, the Archimedes was almost as successful, but ran into the juggernaut of the IBM PC – and the rest is history. Almost. 2 The BBC Microcomputer - A Withered Branch In 1979-80 the British Broadcasting Company (BBC) started the BBC Computer Lit- eracy Project and put out a tender for a microcomputer to accompany the television series The Computer Programme. Acorn was a firm started by two former Sinclair employees, marketing director Chris Curry and researcher Hermann Hauser. Their firm won the tender in April 1981 and released the BBC Microcomputer later that year. The large keyboard unit connected to a conventional television, which became the screen for the computer. Based on the 8-bit Motorola 6502 processor, the initial model had 16k bytes of RAM, and cost GBP 299.
