-
-
- SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
-
- HARDWARE
-
- Amiga 1200 with unused trapdoor expansion slot.
-
- SOFTWARE
-
- None.
-
-
- COPY PROTECTION
-
- None. Well... the board is multi-layered (four or five layers?), so
- I wouldn't want to copy it anyway :-) . And copying the chips would
- probably take a few evenings too... The board is not hard drive
- installable, but you could probably install it into an 8" floppy disk
- jacket. :-)
-
-
- MACHINE USED FOR TESTING
-
- Amiga 1200.
- Toshiba 250 MB 2.5" IDE hard drive.
- Commodore 1940 multisync monitor.
- AmigaOS 3.0 (Kickstart 39.106, Workbench 39.29).
-
- Blizzard 1230-II board with
- 40 MHz 68EC030 CPU
- 40 MHz 68882 FPU
- 12 MB RAM (4 + 8 MB 70 ns SIMMs)
-
-
- INSTALLATION
-
- After any SIMMs, FPU, and add-on cards are fitted, the card plugs
- into the 150-pin expansion connector in the bottom of the A1200. It is a
- rather tight fit. Connecting it isn't really a problem though, unless you
- use two SIMMs -- and if the SIMM in Bank 2 is two-sided, it's REALLY tight.
-
- (See next section about attaching memory, etc., to the board.)
-
-
- PHYSICAL DESCRIPTION
-
- The card has the same basic shape as any other vendor's "1230" card,
- but the placement of the various chips and connectors is a bit different.
- There are components on both sides. On the side that faces the trapdoor lid
- are the 68030 CPU, FPU sockets (both PLCC and PGA), a connector for an
- optional FAST SCSI-II controller card, oscillator(s), a number of jumpers,
- plus some other chips. On the other side are two standard 72 pin SIMM
- sockets, a battery for the real-time clock, and even more chips. On the
- edge opposite the 150-pin connector is a second (custom) expansion connector.
-
- The 68030 is socketed (PGA), so a 40 MHz 68EC030 can be upgraded to a
- 40 or 50 MHz full 030 later. The reason for the two FPU sockets is that the
- PLCC versions are cheaper, but they're not available at frequencies higher
- than 40 MHz, in which case you need the PGA one. For some strange reason,
- the board requires a separate FPU oscillator even if the FPU and the CPU are
- clocked at the same speed (as is the case with my board). The oscillator
- costs about $6, so this isn't much of a problem.
-
- The board accepts industry standard 32- or 36-bit, 72 pin SIMMs, the
- same kind that are used in A4000s, Microbotics/Paravision 12x0, and lots of
- PCs. Any size from 1 MB to 32 MB is accepted. A very rare and extremely
- useful feature is that the two SIMMs can actually be of different size! Any
- combination is possible, from 0+1 via 4+8, 2+16, etc, up to 32+32 MB; I use
- 4+8. The memory is configured with the jumpers.
-
- But the Blizzard's capabilities don't stop there. As I mentioned, the
- board has two connectors for add-on cards. One is used for an optional
- (currently available) FAST SCSI-II controller sub-board. This is a cute
- little thing that rests on the Blizzard "motherboard". It connects via a
- cable to a SCSI port, to be attached instead of the blanking plate on the
- back of the 1200.
-
- The other expansion connector is more of a mystery, although
- according to some magazines, Phase 5 have announced two possible add-ons,
- one of which is an MPEG decoder card (like the one for the CD32). How Phase
- 5 will solve this problem, which the Commodore engineers considered
- "unsolvable", remains to be seen...
-
- Finally, the board has a jumper to enable the mapping of Kickstart
- ROM into RAM (also on boards with the MMU-less 68EC030 CPU). More about this
- later.
-
-
- IN USE
-
- The board is COMPLETELY auto-configuring; just "plug and go". There
- are no software patches, "Expansion" directory files, or anything. It
- doesn't even need a "setclock load" command in the Startup-sequence to set
- the internal Amiga clock! With my configuration, the 4+8 MB RAM was mapped
- to one contiguous chunk at address 0DC0 0000 - 0E7F FFFF. Strange placement,
- but it probably always places the border between the two SIMMs at 0E00 0000.
- A full 64 MB system would thus occupy the space 0C00 0000 - 0FFF FFFF.
-
- I have used the card extensively since I first got it some weeks ago,
- and it is simply a dream to use. I upgraded from an A1200 with 4 MB fast RAM
- and a 68881/14, but it's still a very noticeable step up. I use the Amiga for
- various types of applications; like ImageFX, Imagine, Scala, Final Writer,
- OctaMED, WinGnuPlot, and Amiga Oberon. Software that's sluggish on the
- 68020/14 system -- and that can include several of the above applications,
- with large projects -- now runs MUCH smoother and faster. Of course, the extra
- RAM also makes the machine a lot more stable. Upgraders from stock A1200s
- will probably notice much faster hard disk access, too (SysInfo reports 2.1
- MBytes/second from my internal IDE; I got the same results with only fast RAM,
- but only about half that with the unexpanded 1200).
-
- At first I was a bit worried about heat problems -- the plastic
- trapdoor lid became rather hot, not to mention the 68030 itself. But I have
- used it for longish (18+ hours) sessions, and haven't encountered any
- problems. The temperature seems to stabilize -- at a rather high level,
- though. (Hint: I wouldn't like to sit with the 1200-030 in my lap for any
- period of time!) Some A1200 accelerator manufacturers recommend that the
- machine be used without the lid present, but this does not seem necessary
- with the Blizzard.
-
- As previously mentioned, the card has a MapROM option that copies
- the Kickstart ROM into RAM. Note that MapROM, as opposed to the standard
- AmigaDOS "CPU FASTROM" command, also works on MMU-less (68EC030) systems.
- While this makes a lot of sense on an A500 or A2000 (which have 16-bit
- ROMs), it's not very critical with the 32-bit (but rather slow) A1200 ROMs.
- AIBB tests show a speedup ranging from zero (most of the integer tests) to
- more than 50% (WritePixel) with MapROM enabled, but the typical speedup is
- less than 10%. Obviously, using MapROM will cost you one half meg of RAM.
-
-
- BENCHMARKS
-
- Any accelerator test has to give a few benchmark results, so here
- goes. I have listed the results for all the AIBB 6.1 tests. All figures give
- the performance relative to an unexpanded A600 (7 MHz 68000, ECS, no Fast
- RAM); that is, the A600 score is 1.00 on all the tests. In addition to the
- internal AIBB modules (stock A600, stock A1200, A3000/25, A4000-040), I have
- included the results achieved with my previous setup: A1200 with Microbotics
- MBX1200z, 14 MHz 68EC020/68881, and 4 MB Fast RAM.
-
- The Blizzard was tested with both CPU caches ON, instruction burst ON,
- data burst OFF, and MapROM enabled. 68020 and 68881/2 code was used wherever
- possible. I have not listed the A4000-040 FP results with 68040 specific FP
- code, mainly because it is my experience that very few programs are optimized
- for this (and you can find the 040 FP results in AIBB anyway). For quick
- reference, the fastest machine in each test is marked with an asterisk.

-
-
- I also ran AIBB's "All Tests|Make Module" option, which (after some
- time...) reported that my machine was 1.05 times as fast as the A4000-040 for
- integer operations, 0.67 times for graphics operations and 0.47 times for
- floating point operations.
-
- The AIBB results are about as expected and very similar to those
- achieved with other similar boards. Of course, the floating point results
- are the most impressive ones -- up to 160 times as fast as an unexpanded
- 1200 -- but the integer tests are the most important ones. Thankfully, the
- results there are also rather healthy -- typically 4-5 times the speed of
- the 1200.
-
- The A4000-040 is heavily outperformed by the 1230 in a few tests:
- MemTest, which fully reveals the slow memory system of the 4000-040, and
- Savage, which is slower because the 68040 must emulate the transcendental
- functions of the 6888x in software. On some other tests however, the 4000-040
- is several times faster. A Blizzard-equipped 1200 is somewhere between the
- 4000-030 and the 4000-040 in terms of performance, probably closer to the 040.
-
- I have also tested some programs with the Blizzard board. "mp 1.03"
- (Michael van Elst's Berkeley-based MPEG decoder) runs at up to 8.4 fps in
- 8-bit grayscale with "DebbieHarry.mpeg" (a 160x128 IPB MPEG stream which is
- available on aminet, and which, incidentally, I made myself on the very same
- machine), and 5.5 fps in HAM6. This is about 2.5 times the performance I got
- from my Microbotics MBX1200z setup. "aMiPEG 0.4" plays the same MPEG at 4.6
- fps in full-screen (scaled) DblPAL HAM8 resolution.
-
- As for floating-point performance, CineMorph runs a LOT faster. I
- never timed it with my old setup, though, so I don't know the exact speedup.
- And "rot3d" now flows quite well in full-screen mode.
-
- Just for fun, I also ran a benchmark that we use at work to compare
- our various machines. It came in 30 (thirty) times faster than an IBM PC/AT,
- five times faster than a Compaq 386-387/20 PC, well above the VAXstation
- 3100, at about the same speed as the Apollo DN4500 (which is also 68030
- based) and VAX 8600, slightly slower than the HP-Apollo 400t, but was
- outperformed by a Cray X-MP by a factor of 12, and a HP 9000/730 by a factor
- of 25. Ah well...
-
- Finally, recall that my Blizzard is the 40 MHz version. The 50 MHz
- 1230 should be up to 20-25% faster.
-
-
- DOCUMENTATION
-
- The board comes with a 16-page Users Manual in English. The
- language is clear and concise, although the manual is a bit vague about the
- necessity for two oscillators even with a CPU-synchronous FPU. But
- otherwise, the manual is very good. It includes pictures, figures and
- tables explaining FPU and SIMM installation, jumper configuring, etc.
-
-
- LIKES
-
- I like EVERYTHING about this board: the speed, the unmatched
- flexibility and expandability, the full AutoConfig, and the price. I really
- can't think of anything negative to say about it. One of the things I
- REALLY like is the flexible memory system which allows different-sized SIMMs
- to be used simultaneously, a feature I haven't seen in any other board.
- This system means that you never have to scrap more than one SIMM when you
- upgrade. For instance, when 16 MB SIMMs become more affordable in the
- (near?) future, I might sell my 4 MB one to some PC user, keep the 8 MB one,
- for a total of 24 MB Fast RAM.
-
-
- DISLIKES AND SUGGESTIONS
-
- None!
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- I waited this long with buying a "real" accelerator board for my
- A1200 because I saw major flaws in all the ones previously available. Here
- are my complaints:
-
- Microbotics 1230XA: Only one SIMM slot. Memory doesn't autoconfigure
- under AmigaDOS 3.0. No expansion capability.
-
- GVP A1230 Series I and II: Uses non-standard GVP SIMMs, which are
- more expensive and more difficult to sell when upgrading. If two SIMMs are
- used, they must be the same size. Series I didn't have much expansion
- capability, there's no 50 MHz 68030 option for it, and it doesn't have a
- real-time clock. The new Series II board fixed many of these problems, but
- it's significantly more expensive than the Blizzard and offers no advantages
- over it.
-
- Cheap accelerator boards like the Blizzard 1220 (28 MHz 68EC020) can
- in my opinion not be considered to be "similar products".
-
- I guess another similar product to compare a Blizzard-equipped A1200
- to would be the A4000-030. The 4000 is quite a bit slower, more expensive,
- and, in contrast to the 50 MHz 1230-II, doesn't have an MMU. On the other
- hand, it's more expandable -- 68040 accelerators, 24-bit graphics cards,
- 16-bit audio cards, etc, can easily be added in a 4000. Then again, the
- Blizzard has its two expansion sockets, and the 1200 also has a PCMCIA
- connector. One reason why I've chosen to stick with the A1200 is it is
- physically very portable.. I can just put it in a medium-sized shoulder bag
- and take it along to work, friends' houses, hotel rooms, the summer house, or
- wherever. If there's not a multisync or VGA monitor around (there usually
- is), I can always connect it to a TV -- the 1200 has both SCART, composite,
- and RF output.
-
-
- BUGS
-
- The need for two oscillators might be a (hardware) bug; other than
- that, I have not found any bugs or problems.
-
-
- SUPPORT
-
- phase 5 have listed a phone number, fax number, and mail address for
- owners in Germany. All other users are asked to contact their distributor or
- dealer concerning guarantee claims or technical inquiries.
-
-
- WARRANTY
-
- One whole page of the manual describes the terms of the guarantee. I
- have no intention of quoting all of it. Basically, the board comes with a
- 12-month parts and labour guarantee against material and manufacturing
- defects.
-
-
- CONCLUSIONS
-
- It seems to me that the Blizzard 1230-II combines the best from all
- the other 1230 boards. Two standard SIMM slots. Different size SIMMs can be
- used simultaneously. Full autoconfig. As expandable as the new GVP boards.
- 40 or 50 MHz options. Both PGA and PLCC FPU sockets. Very reasonable price.
-
- On a scale from 1 to 10, I can't help but give it a score of 10. I
- really can't imagine how this board could be improved -- at least not without
- renaming it "1240" (probably infeasible due to heat and/or power problems) or
- "1260"....
