- Blizzard 1230-IV Turbo Board
- ----------------------------
-
- Phase 5
-
- From: Gordon Harwood £179.95
-
- For those of you who have never heard of Phase 5 or their brilliant range
- of turbo boards for the A1200/A4000 and other Amiga's here is a small bit
- of info.
-
- Phase 5 are a German company producing many Amiga hardware bits'n'bobs
- but they have sprung to fame with the Blizzard range of turbo boards.
- All the boards run at chip legal speeds, this means the Motorola chip
- hasn't been altered in anyway to make it run faster, commonly known as
- 'clocking'. This is common practice in the PC world and is starting to
- encroach on the Amiga world. The problem with clocking a chip is it runs
- at a speed faster than it is spose to and this ends with the computer
- locking up at times and worse still the CPU burning out! So you will be
- glad to know that Phase 5 don't clock the chips :)
-
- The Blizzard 1230-IV Turbo Board is an 030 based turbo card for the A1200
- that plugs into the trap door slot some of its features are.
-
-
- 68030 CPU with MMU at 50Mhz
- So this means the average performance of your A1200 will increase by up
- to 500% In tests I found it to run at least 4-5 times faster than a basic
- A1200 and twice as fast as a A4000/030. Now thats speed for you.
-
- A 72 pin SIMM socket that takes the standard single-sided or double-sided
- SIMMS. It will also take the 32 bit sims and the PC style 36bit sims.
- As the 36bit SIMS are in use more by the PC this option could save a few
- pounds. Another bonus is the board auto configs to the SIMM you plug
- into the socket, so there is no need to play around with jumpers.
-
-
- Map ROM function.
- This if set will load the Amiga ROM into fast RAM and by doing so will
- speed up many operations. The downside being it takes up 512k of memory.
-
- Option to install a maths co-processor. If you use your Amiga a lot for
- Raytracing or any other maths work then you can speed up those type of
- tasks by installing a maths co-processor.
-
-
- DMA connector.
- This little interface built into the card will allow a extra SCSI card to
- be plugged in that will give full fast SCSI compatibility. The SCSI card
- also has room for another 128megs of ram. NOTE: this card is an option
- and costs around £90.00
-
-
- Asynchronous design.
- This means if you use a genlock with your Amiga this board runs in time
- with the system clock so all video out put etc will be perfectly stable.
- Some turbo board cannot be used with genlocks so take care.
-
-
- Real-Time clock with recharging battery.
- Why did the old Commodore never put a battery backed up clock in the
- A1200? Anyway this board has one, what else could you want?
-
-
- Installing the card.
- The card was a bit of a bugger to install as its a tight fit in the
- trapdoor but once installed it ran OK even if it did seem to get a bit on
- the hot side. The heat generated worried me so much I took the trap door
- off and drilled a few small holes in it with a hand drill. Then rased
- the Amiga slightly off the desk buy placing a few extra rubber stops on
- the ones all ready on the bottom of the Amiga. This let some air get to
- the turbo board and made me feel a bit better. Although as the Motorola
- chip hasn't been clocked it shouldn't over heat anyhow.
-
- Anyhow the board has been in my A1200 that runs a 24hr BBS 7 days a week
- and it hasn't over heated yet.
-
- Right here comes the only niggle I had with the board, sometimes when
- inserting a disk into the floppy drive the computer would crash. This
- might not be fair to blame the board as I pretty sure its the fault of
- the old Commodore PSU that gives out a very wimpy power. So if you do
- buy this board I think you best think about buying a Goliath PSU at the
- same time.
-
- To sum up if your after a turbo board for your A1200 at a price that wont
- destroy your bank balance then consider this one. The price is right and
- its one of the fastest around and remember the chip hasn't been clocked.
