- for the 50 MHz model with MMU and 8 MB of luurrvely RAM. The memory
- was on special offer and was quoted as being a 60ns SIMM. Insured 48
- hr. carriage and the Gold warranty was included in the price.
-
-
- LIST PRICE
-
- Well, dunno, but it was advertised in Amiga Format for
- U.K. pounds 179.95 for the bare accelerator.

-
-
- INSTALLATION
-
- Before I start: BEWARE. The following describes opening up
- your Amiga's case and if you are unsure of this or still have a
- warranty on your machine then doing this can invalidate your warranty,
- your sanity, and your whole damn machine if you do not take the
- appropriate anti-static precautions beforehand. Please pay attention
- to this. YOU HAVE BEEN WARNED.
-
- I have done this sort of thing before in my machine with a
- previous RAM only expansion and found that it saved a heck of a lot of
- time, effort, and mucking about to just remove the top of the case,
- lift it over, move the keyboard out of the way, pull back the metal
- shielding in the vaccinity of the edge connector for extra safety from
- short circuits, and just tilt the board and plug it
- in. Unsurprisingly, the same idea applied here also. (NB :- if you
- are looking down from the top of the machine the idea is that the
- 'lip' of the board goes ABOVE the support guide rail i.e. inside the
- machine, not outside).
-
- The problem is that the board will not go more than about 3mm
- onto the edge connector by the strength of your fingers alone (unless
- your first name is Arnold and your surname begins with S and is almost
- unpronounceable). I had to use a screwdriver and use the leverage from
- the plastic case of the A1200 to force the git on. Suddenly, just when
- you think you are about to break the thing it jumps forward fully onto
- the connector with a reassuring firmness. Nice one. All done.
-
- There is no heat sink or fan supplied with the board but it
- doesn't say in the manual that it needs one. The memory came already
- fitted to the board by Harwoods. The processor faces downwards so the
- underside of the computer desk acts as one big expensive heat sink. On
- other products my friends have, the CPU faces the underside of the
- keyboard (so you can warm your fingers while typing on a frosty cold
- winter's night ;) . There are two jumpers on the board, one for
- mapping the ROM into Fast RAM and one for the RAM speed
- setting. Mapping your kickstart ROM into RAM will help speed up the
- execution of commonly used system functions, since the ROM is slower,
- even though it is 32-bit wide. Doing so will obviously cost you 512K
- fast RAM. A funny thing here, though. I thought that the ROM was
- copied across into RAM and then the MMU is activated to point to the
- start of the ROM image in fast RAM, but when you run either Sysinfo or
- AIBB they both state that the MMU is disabled or not in use. However,
- when I use the AmigaDOS 'cpu -fastrom' command and then run the info
- progs again they both say that my MMU is 'in use' or 'enabled'.
- Odd. The second jumper can only be set if you have 60ns SIMMS or
- greater. It allows you to decrease the wait states (presumably to
- zero) on your memory . You need this jumper to be set (as long as your
- mem is fast enough) otherwise the INST BURST and DATA BURST modes will
- be unavailable). I enabled both jumpers (mapping = on, faster mem =
- on). You don't have to tell the board via jumpers what memory it has
- on board because this bit is autoconfig. I chose not to replace the
- trapdoor lid after installation because:
-
- 1) It was held rigidly in place by the support rail,
- 2) It provides extra cooling to make a good reliability.
-
-
- REVIEW
-
- Right, you are now ready to try loading Workbench.
- WHHOOAAA!!!!! This thing is excellent. Nice large amount of 'other'
- memory in the titlebar, bootup time reduced to 15 seconds for fully
- loaded Workbench with AREXX, BlitzBlank, Virus Checker, Toolsdaemon,
- fairly lengthy 's:user-startup' and 8-colour high res PAL screen. Same
- stuff took 26 seconds before. A general look around makes you realise
- this is like a completely new machine. 8-Colour mode is blindingly
- fast, 256 colour mode is now *very* useable, icons pop up VERY fast,
- text scrolls like lightening, and GIF decoding feels faster than
- HP-RISC or 486. You can now have backdrops on WB in 256 colours, use
- MUI and AMosaic Web browser or Digital Universe without waiting 'till
- Christmas for all that OOP C++ code to do it's stuff.
-
- How the hell did I live without this before? Oh yeah, I can
- now emulate a Mac at the speed faster than the Uni's IIci as well,
- should I wish it.
-
- There is no software whatsoever with this Blizzard card, but
- what on earth do you need it for anyway? It is completely autoconfig
- and transparent in use . I must say also, that the engineering of the
- board is absolutely beautiful. It is a pity it has to be hidden away
- when it is in use!
-
- There are only two things of software that appear to be
- incompatible with this board. Wordworth 3 for some reason objected to
- it, and I heard that Imagine 3.0 guru's (although it was a very old
- version apparently). Absolutely everything else worked fine including
- Imagine 2.0, Final Writer 4 Lite, etc, etc...
-
- What else can I say about this product? It is fabulous. A REAL
- performer at a bargain price. Buy one tomorrow, you won't regret it
- for a instant.
-
- FAQs (unofficial) from Usenet about this board to be answered
- to the best of my ability coming up next! Check these benchmark
- performance figures out first though...

-
- Sysinfo 3.24 says I am getting 9.90 MIPS.
-
- Notice the cool MemTest figure. This is due to two things,
- one; it looks large compared with the slow memory subsystem on the
- A3640 CPU module in the stock A4000, and two; I got 50 ns SIMMs for
- some reason, when I actually ordered a 60ns one. Luck City!!

-
- FAQ (MINE)
-
- Q1. Is the Fast RAM autoconfig & will games and demos run much faster if
- they are not on a DOS disk, or does it need a patch in the
- s:startup-sequence?
- A1. Yes, it is autoconfig as advertised. Many of these games and demos on
- non-DOS disks are much faster. Some (e.g. platform games) are not because of
- the mainly custom chip usage rather than CPU usage. No, you don't need ANY
- changes to s:startup-sequence or s:user-startup etc. No software supplied
- with it, as stated before. It is plug and go.
-
- Q2. Is the SCSI expansion board available right now?
- A2. Well, I can't verify this but the advert states they will be available
- first quarter '96. However, there is good news because the 1260 / 060 50 MHz
- board also shares the exact same SCSI expansion so there will be quite a
- demand for these ensuring their production. It is 89.95 U.K. pounds, and also
- includes a second SIMM socket. It apparently goes from the expansion
- connector, under the floppy drive, and comes out of that plastic blanked off
- port at the back of the machine.
-
- Q3. Is it SCSI-2 ?
- A3. Yes, as advertised, but I can't check this yet.
-
- Q4. Is the SCSI DMA or not (i.e. will it block all other tasks when accessing
- SCSI peripherals?)?
- A4. Yes, as advertised, but can't check.
-
- Q5. What is the speed of data transfers from the IDE/floppy drive with the
- 50 MHz?
- A5. My Hitachi DK221A-34, 2.5 inch, 340 MB IDE hard drive (1.1 Amp) has now
- gone up from 800K/sec to 1,193,317 bytes/sec according to Sysinfo 3.24.
- Floppy access is now at 22,940 bytes/sec.
-
- Q6. Can it remap Kickstart for shadowing into fast mem (faster execution of
- commonly used O/S functions)?
- A6. Yes, & it takes 512 K of fast to do this. You can either use the
- "cpu fastrom" command in Dos or the jumper on the board.
-
- Q7. Is remapping done by a software patch or jumper?
- A7. By a jumper or by standard dos command as above.
-
- Q8. Is the fast RAM mapped into the PCMCIA port's address space thus
- disabling the use of it?
- A8. No, it puts it way above the port and into the top part of the 030's 4Gig
- address space at $78000000 to $7877FFFF (using 8MB SIMM with Kickstart remap
- on via jumper). This means you can still use the port exactly in the same way
- as before.
-
- Q9. Does it have Inst cache, Data cache, Inst burst, Data burst and can they
- be all independently set?
- A9.Yes, but the Inst burst and Data burst modes are unavailable and appear
- ghosted with RAM access speeds of slower than 60 ns. With a 60ns or faster
- SIMM and the fast mem speed jumper set you can have all 4 modes available,
- and note that no matter how many modes are available, they act independently
- from each other.
-
- Q10. Can it be used for virtual memory with the MMU?
- A10. Yes, VMM etc. works fine with e.g. big custom page on a paint package.
- Without it I can't use 1600 x 1200 pixel screens, and with it I can. Simple
- as that, really.
-
- Q11. What memory does it take? 72/76 pin SIMM? 50/60/70/80 ns? Parity/non-
- parity? Industry standard or GVP? ;) Single or double sided? Fast page mode,
- EDO, or Ultra fast page mode (4K refresh) SIMMs?
- A.11. It takes 72 pin or 76 pin (32 or 36 bit, respectively) SIMMs, and
- ignores the extra (parity) bits on the 76 pin (36-bit) mem. 70 ns
- (nanoseconds) access or faster mem is required for use with this board.
- Parity or non - parity mem usable, board regards them as being identical.
- Industry standard SIMMs with 72 or 76 pins are the only ones usable (NOT GVP
- type). Single or double sided usable. Standard (fast page mode) or EDO
- (Extended Data Out) or the better Ultra fast page mode mem is usable.
- I used a pre-installed SIMM bought with the board which was 8MB, 32-bit,
- fast page mode, 72-pin, 8 chip, single sided, 50 ns, no parity.
-
- Q12. Is CPU surface mounted? Is there a separate socket for FPU? PGA or PLCC
- type usable? FPU clock speeds below 50 MHz usable? 68881 or 68882? Extra
- crystal needed?
- A12. CPU is in a PGA socket, not soldered to board. One socket for FPU, PGA
- type only. Thus PGA FPU usable only. FPU clock speeds below "not recommended
- by Motorola" in manual. 50 MHz only. 68882 type FPU only. No extra crystal
- needed.
-
- Q13. Does it still recognise the hard drive after a warm boot (3 finger
- salute) or does it need a cold boot (off at power)?
- A13. Yes. Recognised after warm boot every time. Recognised after cold boot
- 90% of time (may need a warm boot in about one in every 10 cold boots). All
- early startup menu options usable and it recognises the hard drive every time
- after any option is set. Wonderful!
-
- Q14. Can you completely disable the board and get the machine to act exactly
- like a stock A1200? How? Keyboard, jumper, or software?
- A14. Yes. Just hold down '2' on the main keyboard (not numeric pad) to
- completely disable the board. Hold down ctrl-A-A for more than 10 seconds to
- return to the accelerator.
-
- Q15. Is the clock compatible with all Workbench clock prefs setting programs/
- clock progs?
- A15. Yes. You can set it with sys:prefs/time and show the clock time with
- sys:utilities/clock. It also doesn't seem to get reset or overwritten by
- software failures, EVER. My old ram board's clock did though.
-
- Q16. Does it take a lot of power? Will I need a new supply to prevent
- crashes / lock -up?
- A16. No. I have the 50 MHz 030, 8MB SIMM, and Hitachi 2 1/2 inch hard disk
- (1.1 amp) and I am still using the standard lightweight type power brick (23
- watt). No problems whatsoever, no crashes. I have seen a similar setup with
- Blizzard II in a friend's machine but the hard drive was 1Gig and the power
- light was much duller.
-
- Q17. How long can you leave it on for with SIMM slot used, hard disk, stock
- power supply? Does it get too hot? Does it crash / lock up because the power
- supply gets to hot?
-
- A17. With my set up I have used it extensively (150 hours) since I got it so
- far and it has never gone wrong. This also includes 2 x 12 hours ish renders
- in Real 3D, and a 7 1/2 hour transfer of a 76 meg file down a serial cable to
- a PC at 57600 baud. It does make my desk warm up underneath even though it is
- 3/4 of an inch thick wood. Temperature on the underside of the desk after a
- very long render session feels slightly cooler than hand warm water. It never
- gets any hotter, but remember I left my trapdoor lid off. It never overheats.
- The power supply gets about as warm as a hot cup of tea after 1/2 a day, but
- never any hotter. No crashes / lock ups experienced. Nice.
-
- Q18. Will I have to ever replace the clock battery?
- A18. Not for a couple of years, I reckon. It is self recharging and socketted
- so it can be replaced in event of problems.
-
- Q19. Is it a brand new '030 processor or a factory second/second hand/from a
- Mac?
- A19. It is a brand new beautifully finished, socketted, MC68030RC50B as
- printed on my chip.
-
- Q20. Is it an overclocked CPU?
- A20. No, it is a full 50 MHz 030 processor.

-
- DOCUMENTATION
-
- You get a small manual, but the necessary things are explained
- clearly and concisely. No real technical stuff is explained, but let's
- be fair-this board is just totally plug-and -go!!! The installation
- instructions are in a step by step format.
-
-
- LIKES
-
- Speed !!! 10 MIPS / 20,000 Dhrystones of pure POWER
- RAM expansion !!! (YEAH!!) -any industry standard 32-bit SIMM to 128MB
- SCSI-2 expansion module with DMA & another SIMM slot !!!
- Plug-n-go !!! -no faffing about...
- The integration of the RAM, SCSI-2, 50MHz, MMU
- and no drawbacks into a single product!!!
- Compatibility !!! -with almost all game/demo/serious software available
- Can disable board for TOTAL A1200 compatibility at a keystroke!!!
- Reliability !!! -works perfectly, a dream to own.
- Real time clock that never gets reset!!!
- Is there any better 030 A1200 expansion available anywhere in the world?
- NO!!!
- Am I mighty pleased with my purchase? YOU BET YOUR ASS!!!
- If it could cook would I marry it? Errmmm... I might chose Kim Wilde
- instead, but I can't get her on mail order for 179.99!!!
-
-
- DISLIKES
-
- None. (for once in an Amiga product review...:)
-
-
- COMPARISON TO OTHER SIMILAR PRODUCTS
-
- I was thoroughly sick of reading about other people's problems
- with 1200 accelerator boards and was originally going to buy a
- Blizzard II/III but after hearing other similar rave reviews in
- comp.sys.amiga.hardware I took a chance on Bliz IV. I have seen a Bliz
- II in operation but I don't know about that one in detail. I saw the
- GVP at another friend's house but couldn't possibly afford one at the
- time. It was good though, but needs special GVP SIMMs at slightly
- bigger prices.. It was also a whole MIP slower !?. Go figure.
-
-
- BUGS
-
- None found.
