The HPDrive Project Why and how If you got a working vintage computer system like the HP 9845 you probably want use some mass storage as well. Since today most of the built-in tape drive systems fail (and because using those tape drives as storage - even if they do work - is not recommended anyway), another type of mass storage peripheral is needed. If you own one, a floppy disk drive like the 9895A is certainly a good choice, of course in combination with the appropriate 98034A/B HP-IB interface. If you can't find a 9895A drive or any other mass storage in working condition, emulating a real vintage drive on a conventional PC is an attractive alternative.

What is dlportio? Dlportio.sys is a Windows driver. A driver is a small software program that allows your computer to communicate with hardware or connected devices. This means that a driver has direct access to the internals of the operating system, hardware etc. The free file information forum can help you determine if.

Since the 98034A interface is the only peripheral interface which is directly supported by the 9845 operating system (besides the 98041A disk interface), it is probably a good idea to build this emulator for use with an HP-IB connection. At the PC side, only a suitable IEEE488/GPIB interface card is needed, plus the emulator program itself. The dedicated IEEE488/GPIB interface still is the best choice for compatibilty with old HP-IB systems and in case of doubt (in terms of compatibility) superior to home-brew solutions since those industry solutions have in general been designed and tested thoroughly against the standard. And emulating a real drive behind an IEEE488/GPIB interface has the advantage that drive functionality is totally transparent for the host and there is NO change needed on the host side (such as creating new drivers etc.).

HPDrive Setup Beyond replacing a vintage HP-IB mass storage drive, an emulator has some additional advantages: • Since the data is actually stored at the PC side, it is easy to use this way to exchange data with the PC, just through transferring the data to and from the emulated drive storage. • The emulator can use binary image files as replacement of real mass storage media, so direct archiving is simplified. • The emulator can be configured to simulate different types of drives, firmware revisions and media. • The emulator can work with much higher speed than the original drives.

Certainly, an emulator will never really replace the feeling with a real vintage drive, reading real vintage floppies, making all that noise, and drawing lots of power. But it can be quite useful, especially if you don't own other mass storage in working condition. So I decided to do all that work, scanning all the HP-IB commands which go forth and back between a 9845 host and the peripheral, checking out the manuals which describe higher level HP-IB based command sets like the AMIGO command set, finding out how to low level program those GPIB boards under modern operating systems and whatever was needed to get this task done.

The result was a mass storage emulator program: the HPDrive utility. HPDrive runs as a console application under Windows 9x, ME, NT, 2000, XP, Vista, Windows 7, Windows 8 and Windows 10. Pacote Adobe Cs6 Download Completo Portugues Crackeado.

It now supports the AMIGO, the CS/80, and the SS/80 command sets, early semi-device-independent peripheral controls used over an underlaying HP-IB connection. Those protocols were quite popular at the time of the 9845s, and even the systems which followed the 9845s like the series 80 or series 200 systems mostly supported AMIGO based drives like the 9895A, the 82901 or the 9121. CS/80 and SS/80, which were successors of the AMGIO command set, are widely implemented, however since documentation of CS/80 and SS/80 hard drives in general doesn't include a description of certain drive side routines (so-called 'utilities') and functionality is hard to guess, utilities - as far as they are used by host drivers - may or may not work. Malayalam Kavitha Renuka Download Mp3. HPDrive is by far not restricted to HP 9845 computers.

Due to its generic design, it is now supporting many combinations of host systems and HP-IB drive emulations. However, since my personal focus is mostly on the HP 9845 series in combination with the emulation of the standard drives which are supported by this system, in general this is what is most thoroughly tested. But Series 80, 200, 300, 1000 and 64000 seem to work pretty well, too. Also many instruments which use HP-IB drives as mass storage. Even the Viper cards (HP's measuring coprocessor cards) are running with HPDrive.
