Yes, indeed, but if the user wants to put it in a desktop case, that's his prerogative. Personally, a Tower is the way to go IMHO.

desktop A1200 case is fine as long as you know what you are doing ie add cooling in the right place.

the A1200 case is low profile case so i use blowers to blow the hot air out to the front lower part of the orignal air vents so no extra hole to cut in the outer case.

using orignal feet and trapdoor ( no cutouts )

BLIZZARD PPC 320Mhz with 80Mhz bus........awaiting fix for 83Mhz bus.

** leave the card in a working state** i think this is best for you,as if something go's wrong you be unhappy. if you have problem with 4.77 to 4.78v then do some changes but if it works fine at 4.77v then just leave it.

I think you've missed my point. When I have the floppy connector connected straight from the power supply to the main board - the 5v main line reads 4.97v - but DOESNT boot from the hard disk or floppy drive. It starts to, but then simply stops!!!! Surely 4.97v should be spot on????

However, when it disconnected, I get about 4.78v - which makes it boot from the hard drive/floppy drive.

But in order for machine to turn on and to recognise/power up the bppc card, i need to have the 2 connectors connected first, then I have to remove the floppy main board connector as soon as the green light comes on, to get it to boot!!!

So to summarise, what I do to get it to boot is:

- Both power leads in (4.97v)
- Green power light goes from dim green to bright green
- Remove Floppy Power Lead (from PSU) voltage drops to 4.77v whilst machine is still on)
- System boots!

If I don't pull out the floppy power connector after dim green light has gone full green, then it starts to boot, then simply stops.

Otherwise, if I leave both power connectors, machine comes on, starts to boot, then stops and hangs on the light green screen.

4.77 or 4.78 is not a bad voltage thats good,4.9v is even better and should boot with everything attached.

you should have molex connected with extra power fed-in at the floppy connector via the PSU on the motherboard. NOTE: some users use a split lead here to power both floppy and motherboard at the same time here.

the floppy can then be powered direct from the power supply by one of the other leads (floppy connector lead) **it should boot**

with the above set-up you have lots of wires all over the place,but do what you think is best.

if it fail to boot i would back-up data and try re-install at the new voltage.

** BUT IF IT'S WORKING JUST LEAVE IT AS I DON'T WANT YOU TO DAMAGE YOUR CARD **

sometines it's best to leave it alone.

here on my system it reads 5.01v im using ANTEX TRUEBLUE PSU ( for testing only ) and have no problems whatsoever.

4.7 volts is a little low i reccomend min 4.8v. your set-up you may just get away with 4.7 volt but when it starts to read/write data with the cpu at full load can lead to read/write errors.

some users take the voltage after boot-up,but take the voltage during boot-up and see how much the voltage drops. if you have a CD rom drive add this as well,see how much the voltage drops.

another way to reduce the voltage drop is to have a shorter molex lead but extra power feed is recommend at the floppy connector.

its also a good idea to add a extra fan somewhere inside a A1200 desktop to keep the card cool.

Small improvment no problems found yet with OS4.0 but it's early days (BETA)

DO NOT TRY THIS ON YOUR BLIZZARD CARD THIS CARD HAS MODIFICATION TRYING THIS WILL DESTROY YOUR CARD.

ony a small problem with warp-up under OS3.9

NOTE: you have to find the right 50ns simms.

for some strange reason i have faster 50ns simms which fail to work.
it also seems the layout of the simm card may also play a important part.

its the two chips near the Bvision socket, the chip on the far side and one under the phase 5 heatsink.

i use a washer for the one under the heatsink. but you must check that the washer comes into contact with the chip and the heatsink as well as the CPU and heatsink all at the same time.

the best think about it what iv found if the card starts to overheat it give out more of a early warning ie just crash without any damage to the card.

this is one reason i have a higher bus speed than any other Blizzard card out there,but you have to have the right 50ns simm.

some 50ns simms will fail at this speed.

first link

onboard cooling no wires to connect.
very low noise fans.

i can add something here,its about the ram settings on the blizzard ppc card.

switching from 70ns to 60ns will give you inproved performance,but to get the very best out of the blizzard ppc card you have to use the free config and turn everything off ie no-precharge and so on.

here everthing is faster than 60ns setting i can play all games with a 800x600 with a prelude soundcard enabled using OS3.9.

the performance you will gain will depend on what oscillator/processor is fitted to the card.

theres a small peformance gain under OS4.0

NOTE: this setting will not work for most if you have say 64Mhz and above as you are going to need 50ns simms iv found a few 50ns simms do not work with this setting.

WARNING: with this setting you must have four chips kept cool,if you fail to cool the four chips you will damage your blizard ppc card.

iv started to edit my screen modes as during installation it loads screen modes i can not used. can someone please comfirm the following.

1. under the test screen mode it shows lets say 1024x768 32bit but on the second line it shows 1024x768 24 is this correct for 32bit screen?

2. why is there nothing shown in the picasso p96 mode in the prefs draw?

if you like FREESPACE you should also like SILENT THREAT addon for FREESPACE.

this has not been converted for the amiga but i love this addon.

you be a expert after playing this addon,very hard even in medium settings.
