That looks familiar... ebay auction

Elrick · 29 April 2008, 21:56

This is the same product.

Boot_WB · 29 April 2008, 21:59

Ahhh, the business end of a Blizzard 1230 mkIV (If I'm not mistaken).

Brings back memories of building up my first A1200. Sniff.

Lips2k8 · 07 May 2008, 23:13

do you still have this chip? if so how much do you want for it? do you have the crystal that goes with it?

For a Blizzard 1230/IV the crystal is not required.

Zetr0 · 08 May 2008, 14:56

@Lips2k8

indeed, as fc.studio states the card sets the speed of the FPU to the same frequency of the CPU on the Blizzard card itself.

If however you are intending for the card to go onto another *different board then you may require an Oscillator (crystal) of appropriate size and frequency for that board and FPU. ie. 50mhz

Amigakit sell them, serivce is second to none!

although you can get them on fleabay from time to time

Akira · 08 May 2008, 23:56

Why did you offer me this if you sold it on ebay?

T_hairy_bootson · 09 May 2008, 01:18

Maybe he has more than one?

Got any more Elrick?

I may be interested... if... The price is right!

Akira · 09 May 2008, 15:41

Found it more cheap on eBay, I am not interested in paying double for a used cheap when I can get a new one.

I'm also afer one, any ebay search hints (apart from the obvious)?

Akira · 10 May 2008, 22:22

I just searched for 68882

NovaCoder · 11 May 2008, 04:49

ok, thanks

Hungry Horace · 11 May 2008, 20:10

oops. i should have paid more attention here, i'd like this for my blizzard too if the price is reasonable.

have many times considered the one from http://asb-computer.com but the euro->gbp exchange rate doesnt seem to be in my favour these days :/

Charlie · 11 May 2008, 21:16

FWIW:
50mhz 68882's are bloody hard to find...
...the good news is slower ones aren't (sold by Vesalia for instance)
AND all known 68882's will reliably overclock to 50mhz regardless of their rating without any extra help. (even the 25mhz ones)
This is very good for any A3000 owners stuck using the motherboard CPU+FPU combo. (Well, those with 68882) There's a hack to change the 25mhz clock to 50mhz - you never know, some people may be doing rendering on their unexpanded A3000.

This is NOT true of 68881's which are generally only as 'good' as their rating.

Eclipse · 12 May 2008, 00:58

Hi,

Got any links for this hack? I am interested in an FPU but I dont want to pay through the nose for one.

Anemos · 12 May 2008, 15:38

I could not find easy the FPU@50 !
this time i have one FPU 68882@33 PGA, on my Blizzard 1230 IV !
all looks like fine whit that smaller FPU, sysinfo ect..
thing that is no problem , eh? ?
question : with what program or utilities can test the FPU only?

sorry for off topic ..

Hungry Horace · 22 May 2008, 01:03

@ Eclipse - thanks for the (incrediblly heavily packaged) FPU!

Anemos · 22 May 2008, 01:08

Horace you have Blizz whit FPU now..
make one sysinfo screenshot to see..

Hungry Horace · 22 May 2008, 01:17

er... no! your Mips is (are?) better than mine atm!

Yoto · 22 May 2008, 01:25

I may be mistaken, but apparently there are 20 units of that chip available here:
http://www.questcomp.com/InventoryPa...n=MC68882RC50A
and in this site this guys claim to be known manufacturers of this part...
http://www.motsupply.com/focusparts/MCM-110sum.htm

Zetr0 · 22 May 2008, 02:47

@Yotoxionomai

Thanks for the links

alas i fear you would have to buy in bulk as the minimum order i think is $250

Yoto · 22 May 2008, 11:43

I only need one so...who else needs too...

klx300r · 22 May 2008, 19:28

hmmm what games would really benefit from the FPU?? I know games like ADoom make no use of it and you would think that 3D shoot em uppers would need it most

Graham Humphrey · 22 May 2008, 19:33

Quake requires an FPU I think.

Sorry Akira, I've not been paying attention:
25mhz->50mhz FPU?
Just plug the slower part into a socket expecting a faster one - done!!

A3000 FPU hack:
http://aminet.net/search?query=a3000+fpu

Hope that helps.

For 68882, if tried with a 68881 all the magic smoke will come out.

Eclipse · 25 May 2008, 03:59

Hi Horace,
I couldn't get hold of a CPU box, so did the next best thing without it getting damaged.
We have millions at work but get sacked if we take the smallest of items

although the anti-static bubble wrap found it's way out

What speed will you be running it at? I used to run it at 14mhz as I didn't have a crystal.
In hindsight it would of been a damn sight easier dropping it off.

alexh · 25 May 2008, 10:13

You could buy MC68882RC50 for $1 from http://www.datamemorysystems.com/ until last week when someone bought all their stock

They still have 33MHz ones.

There is a rumour that they can get more but the price (supply & demand) will go to $15 which is still very reasonable.

But to me $15 is too much for a chip you will never ever use.

Zetr0 · 25 May 2008, 13:13

That whole thing seems a bit fishy to me...

I rekon they were inundated with over-seas orders and then googled a price check...

then frantically canceled the non shipped orders to make more money..

Akira · 25 May 2008, 16:08

Could be.
In any case, I got some units

Zetr0 · 25 May 2008, 16:10

@Akira

how many did you plumb for in the end?

Hmmm, very fishy!
Expect 68882's going for stupid money on your local friendly fleaBay shortly.

Zetr0 · 25 May 2008, 20:55

anyone wanna do a group buy on the 33mhz ? imma gonna try and get 20 of them anyone one else?

Will they clock reliably to 50mhz...anyone know for sure (don't want to kill my card)?

Zetr0 · 27 May 2008, 02:26

@NovaCoder

I seriously doubt that it will damage your card, I believe at worse the FPU will just cease to function. and at $1 a pop, i can handle that loss... most 33mhz will happily clock at 50mhz but as with everything there is NO guarantee.

I am getting a few for some up-coming projects
