Blizzard 2060 in Amiga 2000 Problem

[actung_bab]

I got dud amiga blizzard 2060 card in my amiga 2000 i was told mine was probley broken when i brought it , apprently somone tryed install 060 cpu arournd the wrong way and the logic chip needs re programing, which think is impossible as caompany no longer supports amiga . dce , if you hold down both mouse keys can you get into eraly start up and see what boards are showing up . my card didnt even show as ram board

Thanks for the reply mate yep i brought it from you then , thanks for extra info on the card it looks amazing pity though , sorry you lost money on it too . yes i got to send anthony some machines 2000 and a broken 4000 .

Thanks for all that though I'm not having much success with the 2060. I've checked over -- sorry, I should have pointed out I still have the manual for the blizzard 2060 (discovered quitely decomposing in the loft under a load of boxes). I've tried different jumper settings and following what it says, but to no avail. Also btw that blizzard card wasn't in the A2000 bought off ebay sorry if it sounded like that -- I bought the blizzard 2060 way back in the late 90s actually directly from a company (I can't remember where from now!), it wasn't in the A2000 off ebay. It's just sat around unused and gathering dust; assuming the company wasn't lying the last time it did anything was when it was tested by the company I bought it from after returning it to them. I must've given them my (then) home and work 'phone number as that's how I found out about them testing it, they called me at work!

I'm not able with the 2060 inside to get to the early startup. I either get a white or black screen x.x . I can get into this if I remove the card.

As a sort of postcript or addition to this story - and now that I remember it I also recall back in the early 90s (when I had the A1500) that I had a Powerpc board inside it as well. Nothing to do with the CPU of the same name, this was a board made by KCS (european company) and was basically an entire XT PC on a board. The CPU was on the board itself with video being done by the Amiga (so I could have VGA 16 Color but very sloooowly!). Originally bought it for my *very* old WB1.2 A500 (which I still have!) though eventually ended putting it into the A1500 via an adapter card that KCS sold at the time to convert the KCS "trapdoor" board into one which fits into an A1500 or A2000. And now I remember about it -- guess what -- that had problems in the A1500 as well (and this was before I even had the blizzard card). Had to go back to KCS a couple of times probably because of some sort of fault on my A1500 (which at the time I wouldn't have known about). As for the A500 I kept it and still have it now, was going to sell it or trade it in back in the early 90s (when I got the A1500) but was told (when asking about a trade-in) "nobody wants an old amiga with WB1.2 roms any more, has to be at least 1.3!". Sorry I'm going off topic.

As to the whereabouts of the board and adapter I'm not sure. They might even still be about. Maybe! The photocopied manuals I got with it are definately still about!

Anyways back on topic -- prehaps I should remove the 060 CPU and check it over and see if it's been put in the correct way at all? It dosen't look like it's ever been removed! And while I think of it .... although it's not possible to tell just by looking at them btw sometimes when chips die (for example memory chips) they get very hot. None of the chips on the blizzard seem to be getting like that. The 060 CPU just got a little warm though. To tell if it's round the right way I guess I'd also need to prize off the heatsink as well though x.x .

Would put a picture up here as well of the card, would that help at all?

I'm wondering if maybe possibly just prehaps this is some sort of power supply issue. The A2000 (ebay purchase) was being cranky right from the start and needed several power cycles just to get it to start up. I read somewhere maybe elsewhere on this board that more modern accelerators need a *lot* of power and that it may be too much for the power supply. Thinking about it how old is the PSU in the A2000 -- I'm guessing none are younger than 20 years of age now. To elminate this at least I've bought a ATX to Amiga power supply from amigakit. At the very least it should elimiate the power supply from the problem.

my card the cpu doesint even get warm or any temp so you car sounds like cpu whould be fine i leave it as is, this is not 100 % but i think i read where some early amiga 2000
you have to disable the on board cpu this chould be 100 % wrong though

Might have to check the capacitors though I hope they aren't bad. I'm not 100% sure if I can remove and replace them myself without causing any damage. I wonder how easy it is to test/replace them? It looks a lot easier than modern stuff whereby capacitors are the size (almost) of a full stop!

Well I got the PC power adapter eventually and I can say I've managed to advance forwards - slightly. I used the hard drive card (which was in the A2000 when I bought it) and the blizzard card inside the A2000. I was using the hard drive card so that I could at least have something which would boot to WB.

With memory installed in the blizzard card, no joy. Stuck at white screen. Without memory in the blizzard I got to the WB screen though the amiga acted very oddly. It loaded up to WB, but the mouse pointer was completely missing and I had a ludicrous amount of memory free (in the order of about 30 to 40K free).

I also removed, cleaned the socket (best I could) and reseated the 5271 chip (which I found out was the buster chip). Put the blizzard card back in with memory installed back in the blizzard but this time removing the hard drive (Since the blizzard card has a SCSI controller I was thinking *maybe* there's a conflict between it and the hard drive card that was originally in the amiga). More success this time -- although I had no WB to boot to, I got the purple incert disk animation the amiga gives you if it can't boot. Even had a mouse pointer too!

Still trying, right now its gone back to stuck at a white screen again x.x

try holding the 2 mouse buttons in this state and see what says about the 2060 card
from memory its said words to effect defective with mine

I'm no electronics expert but I guess it might be a possibility. Depends on if they have anything to do with supplying power I guess. Don't capacitors that have had it go open or closed circuit though? (Can't remember!).

I've been trying to look over my amiga motherboard btw and two of the tracks near the battery look a bit lousy. Here's a picture (warning -- large picture 300kb) ;

the picture is a bit deciving as it looks different in different light and its dark here so I had to hold a torch and a camera at the same time (flash on the camera you can't see anything). I'll try for another picture tomorrow.

The tracks lead to a chip U801 an M6242B which appears to have something to do with the real time clock.

There are quite a lot of capacitors to look over on that A2000 board! Glad I have a DMM to check 'em with! (a UNI-T UT803).

Looks to me like battery acid damage like one my amiga 4000 mbs and i brought a
Amiga 2000 that looked brand new then i powered it up and wreaked it as the battery leaked aghhh that was mint machine , clean it of as much as possible mind you i say already done as battery has been removed
