Only Ultra 2 SCSI (LVD) 8 bit drives can be connected. A fairly inexpensive drive can be used if more storage space is the only criteria.

Yes, PC’s with a PCI bus on their motherboards can take advantage of Ultra 2 SCSI (LVD) drives. You need a PC Ultra 2 SCSI controller to connect the drive. The data Xfer rate of a disk drive is one important parameter in the overall storage subsystem’s performance, but the data bus (50 Mhz, 66 Mhz, 100 Mhz), carries the data from the drive to the CPU. Microprocessor clock speed , SCSI controller support of a particular drive interface, Ultra SCSI, Ultra 2 SCSI etc.

You cannot have a differential feature, that is 12 meter cable length in PCI based Macintosh or PC’s without a PCI Ultra 2 SCSI (LVD), Low Voltage Differential Card, since Macintosh logic boards and PC mother boards do not support the Ultra 2 SCSI (LVD) feature. Earlier, support for differential drives were available only on high end workstations. Now Ultra 2 SCSI (LVD) Cards are available for Macs and PCs.

Only Ultra SCSI (8 bit) drives can be connected internally or externally. Ultra SCSI 16-bit drives have to be connected via a PCI Card. Ultra SCSI (16 bit) can be used with a card but a performance gap of 40 MB/s exists since Ultra SCSI (16 bit) offers only 40 MB/s (max). Ultra 2 SCSI (LVD) is highly recommended if planning to gain maximum performance with a PCI card.

The answer is definitely yes. However, exactly how you do it depends on the type of Ultra Wide host adapter you have. If it is single-ended SCSI and the LVD disk is multimode LVD, you can connect the disk directly to the host adapter. The multimode LVD interface on the disk will switch to the single-ended mode. If the Ultra Wide adapter is differential (HVD), they can still be connected, however, you will have to use a SCSI expander called an HVD to SE or an HVD to LVD Converter.

LVD, which stands for Low Voltage Differential, was introduced in the SPI-2 document of SCSI-3. It is also called Ultra 2 or Fast-40 SCSI. It uses 3 volt instead of 5 volt logic level and is not directly compatible with the "old" differential (HVD) SCSI. LVD again doubles SCSI data throughput to 40 Megatransfers/sec. Cable lengths are 12 m (40 ft). Single initiator-single target applications may use up to 25 m (82 ft) of cable.

This is a tough one to answer, instead we have made a performance Matrix that gives comparative analysis of drive performance parameters and features with their prices, so that an accurate decision can be made based on performance / price comparisions.

No, Ultra 2 SCSI drives are platform independent. Most of the workstations running UNIX have a SCSI 68-Pin connector or an 80-Pin SCA connector, you can install directly, internally or externally.

Yes, with our I(2) Drive WebDAV server you can connect to your account from Windows "My Network Places". You can also mount a drive from your Mac. There is also support for Linux systems via DAVFS2 to mount to your I(2) Drive.

In addition to the obvious benefits of longer maximum cable length than single-ended and a doubling of data throughput, there are a number of other benefits. LVD/MSE and single-ended offer some compatibility. The lower operating voltage of the LVD bus means lower power dissipation, so the differential drivers can be included on the LVD ASIC rather than having to mount them external to the chip. This results in smaller boards, less heat dissipation, higher reliability and lower cost.

LVD is backward compatible through the single-ended interface if it is multimode LVD. It is doubtful that anyone will build LVD devices that are not multimode. Remember that connecting a single-ended device to a LVD/MSE bus will cause the entire bus to switch to the single-ended mode with its data throughput and cable length limitations.

The Apple High Speed SCSI card has a set of Dip Switches on it; the Rev C doesn't, and the ROM chip date is older than 1989, if it shows at all. The Apple SCSI cards older than REV C don't work in my IIe or IIgs...... The Apple High Speed SCSI card has a printed label on one of the chips showing the name "Sandwich II" on it.

The O drive is your College/Division drive. The College of Arts and Letters O: drive is called "artletter." All faculty and staff in the College of Arts and Letters have access to this drive. This storage space is intended to help you store and back up data or share files with others in your College.

There is a way to use ESDI drives with an SCSI interface (such as a PC with an SCSI card or a Sun workstation). It seems that Adaptec makes a translator which allows you to connect ESDI drives to SCSI controllers. I have an Emulex MD-21 which is the device you want. It is an ESDI to SCSI converter. It controls both 10 and 15 mbit/sec drives and provides a SCSI-1 interface on the other side. The interface will handle two ESDI drives as logical units 0 and 1.

The firmware upgrade changes the way the drive reads out the SCSI id settings. It can therefore happen that after the flash the SCSI id of your drive conflicts with the SCSI id of another device. you see in the table above, the SCSI id 0, 2 and 5 do not change as an effect of the flash. SCSI id 7 is normally reserved for the SCSI controler and should not be used.

One possibility is DMA compatibility. If your memory card is not DMA compatible, then switch 1 on the Apple HS SCSI card should be open (up). Another possibility I guess is a SCSI ID conflict. The Apple HS SCSI card's ID at the factory is set to 7. Here are the Apple HS SCSI card switch combinations: Third, the scsi chain needs termination power to work properly. This is different from termination. Both are required for a properly functioning scsi chain.

Again, because the mail isn't stored on a "local" file system to the login servers, this doesn't happen automatically. If you would like to have it happen for you, though, you can add this line to your ".login" file: This will not only tell you if you have new mail, but also how many new messages you have waiting for you when you run pine.

No. Most cards that are 100% ASPI compliant will work with our drives. However, we recommend using Adaptec SCSI host adapters as this is the brand of adapter that we ship with all our systems, and they are known to be fully compatible with our drives.

I had many problems when I first started with the Iomega Zip on my GS and it isn't the most reliable thing - But it works. Attach a terminator adapter to the back of the remaining port on your external HD - The Zipdrive has a weak termination and requires another terminator source. Last, if you are working on the GS for a long time and suddenly the Zipdrive Icons don't pop up when you load Finder, simply eject the zipdisk and push it back into the drive.

I have had a Zip Drive hooked to a CMS SCSI card (1990 ROM) for 2-3 years in my IIgs without a hitch. Basically you just go into the setup for the CMS card. It will partition the drive into 32 meg sections which you can access two at a time-- It makes three on a Zip disk. Then once GS/OS is booted it tells you that the disk is unreadable and asks if you want it formatted and you hit ok for each virtual drive and there you have it.

These are general-purpose analog signal-input ports. The most common use is door-position sensing with magnetic door sensors. Other devices which are commonly used with these ports include water sensors, smoke alarms, and current transducers. The ports have an input voltage range of 0 - 5VDC; in addition, a weak pull-up is provided on each input, allowing the ports to measure passive devices such as dry-contact switches.

If you want an LED to show when a drive is being accessed, you need to connect the LED to a pair of pins designated on the particular drive for that purpose. No one signal on the SCSI bus indicates drive activity. The bus goes through many phases in the process of accessing a device, and signals are re-used for multiple purposes. While you could design a logic circuit that decoded the SCSI signals and activated an LED at the right time, it is way too much work to do it that way.

Multimode LVD and LVD/MSE (Multimode Single-Ended) are terms for the same interface. It is an implementation of SCSI that automatically switches between the LVD and the single-ended mode. When a single-ended device is connected to a multimode LVD/MSE bus, the entire bus switches to the single-ended mode. Otherwise LVD/MSE devices operate in the LVD mode.

No software of any sort can truly low-level format today's modern drives. The ability to low-level format hard drives was lost back in the early 1990's when disc surfaces began incorporating factory written "embedded servo data". If you have a very old drive that can truly be low-level reformatted, SpinRite v5.0 will do that for you (which all v6.0 owners are welcome to download and run anytime).

All Solar Converter charge controllers except for the smallest have an LVD function or an LVD driver to control an external relay. To prevent low battery voltage from destroying your battery, the unit can be used to disconnect the load from your battery when it's out of charge to prevent damaging it. Normal operation resumes once the battery has received some charge either from the PV charge controller or auxiliary charger.

No. Unless you have other SCSI devices that are enhanced by these features, you will not need these cards. All three drives designations represent the same model. Some of the 2022s are OEM drives. After the firmware update, the drive will show up as a 2626. Assuming Z: is the CD-ROM/CD-R drive that the Easy CD Creator installation disk is loaded, MANUAL.PS is the file you wish to print, and your printer is connected to LPT1: Windows 98 tries to read the contents of a blank CD when entered.

It is a 30% discount off your water bill.

Ultra SCSI, defined in the SPI-2 document of SCSI-3 offers a maximum data throughput of 20 Mbytes/sec for Narrow (8-bit) SCSI. Ultra Wide SCSI is the 16-bit version that offers 40 Mbytes/sec data transfers. Ultra Wide single-ended SCSI has a maximum cable length of 1.5 m (5 ft) with more than 4 active IDs and 3 m (10 ft) with 4 or fewer active IDs. Ultra Wide differential SCSI has a maximum cable length of 25 m (82 ft).

To move one or more files, you'll need to open the windows for your local hard drive and your Connect 2 School "My Documents" folder. Once these are open, you can drag documents between these storage areas. Open the folder containing your files on your local hard drive (____ on Client Drive) using the above FAQ. Leave this window open. Now open the "My Documents" folder (H: Drive) on your Connect 2 School desktop.

The AKAI's (s2000/3000/3200XL) O.S. currently indexes not more than 510MBytes of space - and talking about space, the maximum partition dimension is 60MBytes. There is no use in buying a 2GB HD because the rest of the space will never be used under AKAI OS at the moment and you cannot even create a double partition in order to use the rest of the unindexed space for your PC because it is completely incompatible with AKAI's OS way of working.
