A1200 floppy problems
« on: March 07, 2006, 11:51:40 AM »
I have just received my Amiga 1200 won on ebay.

It's got a few anoying problems (ie: A1 condition :pissed: : the hard drive wasn't even screwed down, and was being held in by two broken rubber bands. The Blizzard '30 wont slot into the machine unless I remove the heat sink that was attached. I can live/get around those two. The case screws were loose.

What is anoying me is that the floppy drive is stuffed     :madashell: It wont format or read flopyp's. Even freshly working/formated ones from my A500.

I'm wondering if this is normal practice for A1200's to have this model of floppy: Panasonic model JU-257A51P, and on the end of the ribbon cable where it connects to the motherboard is a little circuit board with two resistors, a diode, a capictor and a IC (I would take a photo, but my camera takes crap shots at close range) with these markins:

Made by Philips

TL      74HC03N
HA      960900PS
AN      Hnn9501PC
ID

Is this floppy drive a standard PC floppy with a converter? (Cool if it is as I have heaps of PC floppy drives I could use). I'm rather pissed of if this drive is a standard amiga floppy (it trys to format the floppy as 880K) as they are very hard to find now.

I think the Panasonic drives are indeed the modified standard PC drives which sometimes refuse to load certain games. It sounds like your drive is stuffed.

the floppy maybe is dirty, try a disk cleaner sometimes makes miracles. the bliz030 don't have any heat sink, maybe this card is overclocked or has some kind of troubles.

If i am going to have bugs on my system,
at least let me keep the latest versions.

... or maybe the previous owner thought it was sweet and nice to add a heatsink on a such hot CPU.
Mine doesn't have one too and doesn't crash, that is the PSU the main responsible of crash on a Blizzard card.
For the Circuit at the end of the floppy, I thought about the "A357-REAL HD adapter" that allow you to use a PC drive.

I must be going blind in my old age!  :-D  :-D

On the back of the circuit board:

Amiga Technologies 1996 (At the top)
Artwork by DCE (Part way down)
318010-01 (At the bottom)

Does this give anyone more information, and does it mean I can use a standard PC floppy drive?
