Hi!

I'm in need of atari mega st internal power supply photo - i've desoldered one part that needs to be reinserted in certain polarity assuming its shown on PCB as its usually is, but not this time - now i don't know how it should be soldered

i know there are several diffrent brands and pcb for this power supply, as i'm using another one, but still want to repair this one
this one features quite big sharp optocoupler (white/cream chip) in the middle of pcb

Candle, here are 2 quick pics I had on my HD. If these don't give you what you need, let me
know, I can pull my Mega ST4 offline and snaps some pics there. Take me about 5 mins to get
it apart (I've done it many, many times).

first one is the version i need, just can't quite see anything on that picture
if You could make some hi-res picture Ronald, it would be great

Well, unfortunately those are just pictures I had on my hard drive. I don't actually
have that first P/S here.

I'm not sure if it will help or not, but I took a few pictures of the ones I did have
here - although they don't look exactly like that first one.

Sorry I couldn't be of more help. You might want to post this same question at
Atariforum. You might get lucky there.

bummers
but thanks anyway
maybe someone else will have the one i need
would not want to register on yet another forum i spent too much of my time here already

[DarkLord]

I went ahead and posted a request over at AtariForum - hopefully someone will be able
to help. If they do, I'll post it here.

Keep your fingers crossed.

I have some MegaST's laying around. Dug them up only a few weeks ago, disassembled, cleaned, put everything together again and put them aside :-)

If there's still no reply after a few days, bump this topic.

First MegaST I opened seems to have another PS but I'll attach a pic anyways.

This one is in my Rev1 Mega 1.

[candle]

just a remainder

Checked my other MegaST and it has the same PS as above so both mines are different.

Whew, I'm glad. Was beginning to think you had the only Mega ST left with that power supply.

Thanks go to 1024k (Mark) at AtariForum.
