- BRIEF DESCRIPTION
-
- Oktagon 2008 is a SCSI-2 controller card with up to 8MB of RAM for
- the Amiga 2000/3000(T)/4000 models of personal computers. The card also
- functions as a hard card, with supplied mounting hardware.

-
-
- LIST PRICE
-
- I do not know the list price of the product, but I paid $129.95 (US)
- from my local Amiga dealer in Portland, OR, USA.
-
-
- SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
-
- HARDWARE
-
- A SCSI-1/SCSI-2 3.5-inch or 2.5-inch form factor hard drive
- is required for operation. I have installed a Quantum 1080
- Empire SCSI-2 hard drive on my controller card.
-
- [UPDATE: "It is not. I use the Oktagon 2008 with only a
- CD-ROM attached."
- Thanks to c.creutzig@hot.gun.de (Christopher Creutzig)
- for this update. - Dan]
-
- No RAM is required on the card for operation, but ZIP style
- sockets provide for up to 8MB of Fast RAM. 1X4 ZIP chips in
- groups of four, either Static Column or Page Mode, are
- supported.
-
- All sizes of hard drives are supported, as long as they
- are as I described previously.
-
- The card is processor independent for compatibility, but
- a faster CPU probably means faster speed.
-
- Supports all current Motorola CPU's including the 68040.
-
- SOFTWARE
-
- The Oktagon comes with its own HD toolbox, on a single,
- autobooting, double-sided, double-density 720K floppy disk.
-
- Surprisingly, it works with all revisions of the AmigaDOS.
- All features are implemented with the latest revision of the
- OS, while some selections are ghosted out for older
- revisions (like AmigaDOS 1.3 and below).
-
- Full functionality is obtained with AmigaDOS 2.1 and above,
- yet even though compatible with AmigaDOS 3.0, it doesn't
- seem to take advantage of any of the newer features present
- in 3.0 as far as I know. As the Oktagon is a Zorro II card,
- this may be the reason for this decision.
-
-
- COPY PROTECTION
-
- None.
-
-
- MACHINE USED FOR TESTING
-
- Amiga 2500 (rev 4.5)
- 2 MB Chip RAM, 4 MB Fast RAM
- Kickstart version 37.300, Workbench version 38.35 (AmigaDOS 2.1).
-
- INSTALLATION
-
- Installation is simple, as the Commodore Installer software is
- used. I selected the "Expert" mode, and found most of the defaults to be
- standard, so even the "Novice" mode wouldn't be much different. You can even
- choose the language in which the installation will occur (English is the
- default, while French and German are supported), and if you have AmigaDOS
- 2.1 or above, locales are also supported. The Amiga Style Guide is completely
- supported throughout the entire installation process.
-
-
- REVIEW
-
- The Oktagon 2008 is a SCSI 1 and SCSI 2 host adapter for the Amiga
- 2000 family of computers, and supports the A3000T, and the A4000 as well.
- The card is packaged quite securely, and comes with the mounting hardware
- for the drive, a short, but easily installable 50 pin ribbon cable, and a
- power cable.
-
- The documentation is written in a "German first, English second"
- booklet labeled "Harddisk Controllers & HD Installation Tools". It was well
- written, and includes both a step-by-step and expert installation
- description. Throughout the book were suggestions, warnings, and helpful
- tips about hard drive installation, use, and maintenance.
-
- [UPDATE: "The documentation unfortunately leaves out a lot of
- important subjects. For example, the terminators on-board are
- nowhere described. They are there, nevertheless, and as soon as you
- get an external drive attached to the controller, you will have to
- pull them out (the two black lines next to the connector for the
- internal drive), unless you do not use an internal drive."
- Thanks to c.creutzig@hot.gun.de (Christopher Creutzig) for this
- update. - Dan]
-
- After I assembled the hard card, and powered up my A2500, the
- installation software had an automatic mode by default (which I don't
- recommend, unless you want one single partition), or can be changed to
- manual mode (for creating multiple partitions). After selecting the
- appropriate mode, you can set the number and size of partitions by using the
- intuitive editor. One caveat here, though, is that you must specify the size
- of the partitions in blocks, so a calculator is handy.
-
- Once the size and number of each of the partition(s) are set, then
- you have to format each using the AmigaDOS "Format" command from a gadget
- tool on the requester. Depending on the size of your drive, this can take
- quite a while for large drives, and seems more like formatting a large
- floppy than a hard drive.
-
- After formatting your partition(s), you can either install AmigaDOS
- (for which there appears to be no utility included), or restore from your
- favorite backup program. One nice feature is the ability to update the
- AmigaDOS type through the corresponding utility. You can also save the RDB
- contents to a file on a floppy should disaster strike, like a corrupted RDB
- sector.
-
- All in all, this is a fine product from a supportive and growing
- company, and I would highly recommend getting the card if you are in the
- market for a fast and inexpensive host adapter.
-
-
- DOCUMENTATION
-
- The printed documentation comes in a 136-page, perfect bound
- booklet, with the first half in German, the second in English. My
- congratulations to the writers for the excellent translation and low
- spelling error count. The docs are very straightforward, and cover every
- aspect of installation, use, and maintenance. All levels of expertise are
- covered, and beginners to experts alike won't be disappointed or confused by
- the nomenclature.
-
-
- LIKES AND DISLIKES
-
- I like the ease of use, the intuitive system that is completely
- style guide compliant, and the use of many of the advanced features found on
- the more recent AmigaDOS upgrades.
-
- About the only dislike I had was that in order to properly partition
- off the hard drive, I had to enter the number of blocks manually. This
- requires a calculator, or figuring out manually the size of the partition(s)
- in blocks, rather than using the sliding type of gadgets found on other,
- more intuitive installation tools, like Commodore's HD Tools. My suggestion
- to BSC: dump the manual entry of partition block size, and use sliding
- gadgets with a readout of partition(s) size in megabytes.
-
- One surprise was the inclusion of the program GigaMem. This virtual
- memory manager is included in the startup disk supplied, and includes the
- documentation, but not the registration. I will give a review of GigaMem
- v3.0 in a later installment, after fully testing and evaluating it. As it
- sells for $79.95 (US funds) at my local Amiga dealer, it makes for the
- frosting on the cake, so to speak.
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- I have owned three hard drive controllers and three hard drives in
- the past several years, and the Oktagon compares quite favorably. As it
- stands, it's easily the fastest and most compatible of the three controllers
- I have owned. Unlike previous products, this one was up and running in less
- than half an hour, which by my previous experience is a record. The external
- 25 pin SCSI connector is also a plus, and has provision for both snap-in and
- screw-in connectors, while past controllers used only one or the other.
-
- BUGS
-
- None noted.
-
-
- VENDOR SUPPORT
-
- Full addresses and phone/fax numbers are supplied, but the hotline
- for technical support is sent back only after registration card is received
- by BSC. I am not associated with the vendor in any way other than being a
- satisfied customer of BSC/Alfa Data.
-
-
- WARRANTY
-
- Full one year warranty on parts, and the installation software.
- Warranty appears to be transferrable, as no mention is made about the
- transfer of title to warranted merchandise.
-
-
- CONCLUSIONS
-
- This is an excellent product at a fair price. Considering the
- performance capabilities exhibited, I would hazard a guess that the faster
- your machine, the faster the throughput. According to SysInfo 3.14, I get
- 2.5 MB/sec reads, and 2.48 MB/sec writes. Diskspeed 4.2 also gave very high
- marks, and I will UUencode the tabulated results to anyone with a valid
- E-mail address, if requested. Seek speed showed my drive had seeks of about
- 6 ms from beginning to end of each partition, and 2 ms average seek from
- adjacent tracks, and 4 ms for 8 random seeks on 90 percent of the drive. It
- would appear that faster processors coupled with faster drives will produce
- the best results, naturally enough, but faster than your average comparable
- equipped host adapter. I'd give BSC and Alpha Data (the manufacturers) a
- rating of 4+ stars out of 5, and a full five stars if they make the
- appropriate changes to the partitioning software.
