Included are sections on system set-up, basic operation, installation of additional peripheral devices and basic theory of operation. You may find upon first reading through this manual several terms and concepts with which you are not familiar. This , of course, is due to the fact that the personal computer is the result of new and fast changing techno­ logies. Although it is not necessary to fully understand these technologies, the learning of a few basic concepts and the ter­ minology (or "buzz words") used to describe them will prove invaluable as you begin to use your computer . A glossary of computer terms has been included to help you through the early learning process. The first-time user of a personal computer may also find it useful to discuss with his computer dealer (or a local computer club) the various computer publications for beginners. Many well written text are available describing basic computer operation as well as the many programming languages available for use on your Heartbeat computer. Remember that your personal computer is a "tool" . A strong understanding of that tool and its capabilities will broaden the nature and scope of problems which it will solve . 1 ***** I NTROD UCT I ON * ** * * The D-G Heartbeat is a compact computer system designed to be hardware and software compatible with the popular Heath/ Zenith Z89 / 90 computer product line . The Heartbeat offers advanced features not found on the standard Heath/Zenith computer such as 4 MHZ operation, real-time clock/ calendar, two RS-232 serial ports , five peripheral expansion slots , 128 Kbytes (expandable t o 256 Kbytes) p arity checked RAM and provisions for an optional AM95ll Arithmetic Processor. The Heartbeat may be used with most popular video terminals on the market although the Heath/ Zenith H/ Z19 , H/Z29 and ZT - 10/ll video t erminals are recomme nded for full Heath/ Zenith software compat ibility. The Heartbeat cabinet design provides for inclusion of hard and/or floppy disk drives as well as other desired pe r ipheral inte r faces a nd is color­ coordinated for use with the Zenith Z29 and ZT-10/ll video t e rminals . A typical Heartbeat system will consist of the Heartbeat "main­ frame" with two floppy disk drives installed , a video terminal and a prin t er. In this configura t ion the lower d i sk drive will be Drive "0 " (or "A" in a CP/M system) and the upper disk drive will be Drive "1" (or "B" ) . Since many othe r Heartbeat system configurations and options are available , the user should discuss his particular system configuration with his dealer before attempting to use his Heartbeat system. 2 Physical Description The D-G Heartbeat is packaged in a compact metal enclosure which may be placed o n a d esk top or "hidden" wi thin the desk o r work cabinet .

  • VPIP (Vinculum Peripheral Interchange Program)
    VPIP (Vinculum Peripheral Interchange Program) (Beta Version – 24 February, 2014) With the recent introduction of the Universal Serial Bus (USB) interface cards for the Heathkit H8/H89 computers (http://www.koyado.com/) these classic machines now have the ability to access files on USB media such as memory sticks. This is a significant step forward for these computer systems, which previously have relied on floppy-disks for removable storage and backup. The heart of the USB capability is the VDIP-1 interface module from Future Technology Devices International (http://www.ftdichip.com/) running the Vinculum VNC1L Firmware. This module and firmware implement all of the details of the USB interface protocol. The purpose of the VPIP program is to provide a convenient interface to the USB device from the HDOS command prompt. VPIP is loosely modeled after the PIP utility provided with HDOS, however it only implements disk-to-disk copy and file listing (directory) commands. You’ll still need PIP to delete, rename or copy files to the screen or printer. Similarly to manipulate (copy, delete, rename, etc.) files on the flash drive you’ll need to use a personal computer or other device. VPIP currently can only be used to access storage devices via the USB port, not printers, keyboards or other accessories. You can run VPIP two ways: with a single command provided on the command line, or interactively. To run VPIP interactively type VPIP at the command prompt: >VPIP :V: The :V: prompt will be displayed at the left margin of the system console whenever the VPIP program is awaiting input.

  • MEDICAL DEVICES: SECURITY CHALLENGES for Hdos and MANUFACTURERS
    W H I T E P A P E R MEDICAL DEVICES: SECURITY CHALLENGES FOR HDOs AND MANUFACTURERS RICH CURTISS | DIRECTOR, COALFIRE INTRODUCTION This paper aims to help organizations understand the issue of security in the context of medical devices. Medical devices have not historically been included in HIPAA compliance regulations or healthcare security and risk programs, yet their capabilities make them prime targets for exploitation. Increased connectivity of medical devices has exposed them to cyber attacks from which they not were designed to prevent. At stake are both patient safety and privacy plus healthcare delivery organizations’ (HDOs) network security. One objective for this paper is to get this issue on the radar of HDOs. We’ll also review the benefits of ‘security by design’ and the concept of embedding security into devices for medical device manufacturers as they seek market differentiation, rapid go-to-market capabilities, and security throughout the product life cycle. SAFE VS. SECURE In the age of the digitized enterprise, the security of electronic protected health information (ePHI) is paramount on every front and endpoint. HIPAA does not regulate medical devices, but it does impose requirements on covered entities and business associates for the safeguarding of ePHI that is created, received, maintained, or transmitted. For this reason, medical devices should be included in HDOs’ HIPAA security programs, and security should be embedded in every stage of a device manufacturer’s product development lifecycle. Beyond patient privacy, the lack of medical device security can be a patient safety issue if an attacker is able to compromise them.

  • Speeding up Your Heath H-89/90
    Speeding up your Heath H-89/90 Now that you have installed the Z67-IDE, you are probably still 'WOWed' by how much faster it boots and runs with the quick read/write access on the Z67-IDE. WARNING! Speed is addictive! So, now you want to make the processing faster as well. This is rather easy on the H-89/90 computer and requires NO modification to the CPU circuit board. There is a speed modification board that is available from Norberto Collado that simply plugs into a socket and will give you software selectable 2 or 4 mega-hertz operation. By-the-way, you don't have to be running the Z67-IDE to use the Speed Board. It will work just as well for a floppy based system. What's Needed: OK, it is just a bit more complicated than what I just said. You also have to replace the CPU chip with a Z80A (4 MHz) or a Z80B (6 MHz). Occasionally, the installed memory chips aren't fast enough and also have to be replaced with faster chips. The good thing about this modification is that if you install it and it doesn't work because the memory is not fast enough, you simply simply continue to boot and run at 2 MHz just like before without modifying the software. Then, after acquiring faster memory, install the new memory chips and perform the speed test. You should now be now be able to run at 4 MHz. Once the hardware modification is complete, there are still some software changes to be made.
