- SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
-
- HARDWARE
-
- An Amiga 1200.
-
- SOFTWARE
-
- None.
-
-
- COPY PROTECTION
-
- None.
-
-
- MACHINE USED FOR TESTING
-
- Standard Amiga 1200:
- 14 Mhz 68EC020, 2 MB Chip RAM, AGA chip set
- AmigaDOS 3.0
- 1 internal 880K floppy drive
- Western Digital (Caviar2420) 405 MB 3.5" IDE hard disk (internal)
- 1 external 1.76 M floppy drive
-
-
- INSTALLATION
-
- Installation is quiet easy. There are no switches and no setup
- program. You simply open the trapdoor and push the device into expansion
- port. The manual explains installation in 2 paragraphs with 2 pictures.
-
- Unfortunately, I had a trouble with the installation. The metal
- cover of my A1200's main board did not allow me to install the board
- easily. Probably my 3.5" hard drive inside puts some pressure on the metal
- cover. I made some bendings on the metal cover near the expansion slot.
- Now it works without any problems.
-
- If you have a 2.5" hard drive in your A1200, this will not be a
- problem; otherwise, you will need a little effort to fix it.
-
-
- OVERVIEW
-
- When you open the black box, you will find a booklet and a Blizzard
- 1220 card in antistatic pocket. It is a good quality product with a well
- designed printed circuit board and electronics.
-
- The parts of the product are:
-
- * 4 MB RAM
- * Additional RAM socket
- * 28 MHz 68EC020
- * Clock & calendar
- * Optional FPU socket
-
- Lets look at those parts individually.
-
- 4 MB RAM
-
- There are factory installed 8 memory chips (DIP) on the board. Its
- access time is 70 ns, and it is 32-bit-wide autoconfig Fast RAM. (DIP -
- Dual inline pocket.)
-
-
- 4 MB ADDITIONAL RAM SOCKET
-
- It is possible to add 4 more MB of RAM directly into the board. The
- booklet says you may order a BLIZZARD 1220/4/ADD4 memory module for this
- upgrade. But I think they are ZIP type RAM chips. (I didn't see any ZIPs
- before; I'm not sure.) You can upgrade your card to 8 MB maximum. (ZIP -
- Zigzag inline pocket)
-
-
- 28 MHz 68EC020 PROCESSOR
-
- On this card, there is a 68020 processor faster than the one in your
- A1200. Your machine will run twice as fast with this processor and twice as
- fast again with 32-bit Fast RAM. The result is A3000 or A4000/030 power.
- It means your A1200 will be 20 times faster than an A500 on integer math.
-
-
- CLOCK & CALENDAR
-
- There is a battery backed up clock on this board. Its very useful
- for programmers, database users, and other people who have a need for files
- with accurate timestamps. It has rechargeable batteries. Batteries aren't
- included in the warranty.
-
-
- FPU AND CRYSTAL SOCKET
-
- You can add a PLCC type 68881 or 68882 FPU (Floating Point Unit)
- running at 14 to 40 MHz on this board. If you choose a 14 MHz 68881 or 28
- MHz 68882, you don't need an additional crystal.
-
- There is a switch with "14 MHz" and "28 MHz" positions. There is
- another switch for an FPU faster than 28 MHz. In this case, you must add a
- crystal for it. For example, if you use 33 MHz 68882, you need a 33 Mhz
- crystal to support its clock speed.
-
-
- BENCHMARKS
-
- The board has really satisfied me with its speed. I wasn't expecting
- its power before buying it. Here are some benchmarks.
-
- AIBB 5.5 (020+ optimized code, and comparison base is A500 NFR)
-
- This Machine A3000/030 A4000/040
- Write pixel 11.57 4.10 26.12
- Matrix 10.64 10.14 16.22
- Sieve 9.95 9.28 11.88
- IMath 20.06 18.29 41.66
- Dhyrstone 6.43 5.96 18.96
- MemTest 8.34 6.70 11.54
- Sort 7.13 7.13 19.67
- TGtest 3.36 1.62 2.93
-
- As you see, with this board, the A1200 slightly faster than an A3000.
- AIBB doesn't have results for A4000/030, but they must be similar.
- Another good point is my hard drive operations have gotten faster.
- Before, I could read a maximum of 900 K/sec with a 256 KB buffer from
- my 3.5" IDE hard disk. Now, results are much better.
-
- DiskSpeed 4.2 (WORD aligned, MEMF_FAST, 70 MB partition)
-
- File create 45
- Open file 112
- Dir scan 439
- File delete 284
-
- seek/read 797 seek/sec
-
- 4 K buffer ..... Create 470 K/sec
- Write 632 K/sec
- Read 988 K/sec
- 16 K buffer ..... Create 616 K/sec
- Write 921 K/sec
- Read 1011 K/sec
- 64 K buffer ..... Create 833 K/sec
- Write 1164 K/sec
- Read 1407 K/sec
-
- CPU rate: 1164 CPU available: 36% CPU avail index: 420
-
- As you see, with this board the IDE driver speed is very close
- to SCSI speed.
-
-
- DOCUMENTATION
-
- It comes with printed documentation in both English and German.
- Only you have to know how to install and how to add a FPU. The booklet has
- enough explanation for both.
-
-
- LIKES
-
- An AGA machine behaves differently when you add Fast RAM. A 256
- color Workbench has acceptable speed now. I have 2 Meg free Chip RAM for
- graphics. Image processing programs run much faster. I can make a 25 frame
- morph without leaving the machine half an hour. Compression and
- decompression are not painful any more. I can see a moderate JPEG picture
- in 3-6 seconds. Hard disk operations are much faster, and icons appear in
- your windows without any waiting!
-
- I bought it primarily for the 4 Meg RAM and the clock, but I couldn't
- imagine how fast it is with a 28 MHz 68020. I like it! For this price, I
- get the the power of an A3000. It's very interesting. Adding a 40 MHz 68882
- will give an acceptable speed for floating point arithmetic and 3D
- rendering.
-
-
- DISLIKES AND SUGGESTIONS
-
- I would like some luxuries! There should be a software switch for
- 14/28 MHz and to disable/enable board features. Also, I don't like its RAM
- expansion. I prefer SIMM upgrades, which are easy and cheaper.
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- I didn't see any other 68020 accelerator for the A1200 on the market.
- There are a lot of 25 Mhz 68030 accelerators that give the same result, but
- they are twice as expensive.

- CONCLUSIONS
-
- It's a very good product. Well designed. It has the best
- price/performance ratio if you compare it with similar products. In my
- opinion, you don't need highly expensive 68EC030 cards for this speed.
-
- If you use your A1200 for programming, desktop publishing, graphics,
- painting, animation, and video work, you need some speed and some Fast RAM.
- The Blizzard 1220 is very affordable solution for it.
-
- If you are a 3D artist or you need a rendering machine, you should
- add a 40 MHz 68882 FPU and 4 more Megs of RAM. (Or better to buy an A4000/040!)
-
- I can't understand why Commodore (RIP) didn't put a 28 MHz 68020 and
- 2-4 MB Fast RAM on A1200 as standard or as an A1200+ model. It gives really
- acceptable processing speed for a home computer. It doesn't cost too much,
- and 3rd parties could survive by producing faster 68030, 68040 and 68060
- boards.
