My 500+ Project

So many goodies...  who was a good boy lately

lol does your better half realise the postie is delivering all these new computers bits?

Lol, naughty boy is more like it, have been going over my monthly "toy allowance" by quite a bit lately. :whack:

Funnily enuf I went for a walk at lunch and just came around the corner as he had left my place so I waved and he pulled over on the street and gave me my parcel after I signed his little PDA thingo. He's never really asked me what all my parcels are tho.

My NOS 1200 arrived today!



I had to clean the cables and remove Petro's Sig from the top of the case but the a1200 is in spectacular condition!

[djos]

Yaaaaay! It works great too!





So I chucked in my ACA1220 and that  works great also:



Im just running some ram tests on it now to see if it's stable (& so far it is).

EDIT, no memory errors so maybe i dont need the timing fixes?

[djos]

Thanks Gertsy! I'll be dead before this beauty leaves my possession!

[djos]

Awesome Amiga you have there!

Very cool that he signed it...  should have signed the bottom tho

Az

Yeah I was slightly annoyed he signed the top when I asked him to sign the bottom only and he only signed the top and the Box.

[djos]

There is any test which indicate that the A1200 mobo' needs any time fixes ?

Im not sure, it's seems 100% stable so far but i'll be able to test it more once I get my CF-IDE adapter from Kipper in a few weeks and can run some AGA demo's. The OCS demo's & games I've tried so far have have been flawless.

Btw folks, my 500+ is now officially for sale (SWMBO has decreed I will sell it as promised):

It was my Birthday last week and my awesome wife bought me a couple of retro T-Shirts:

[djos]

and today I got the below IDE-CF Adapter which seems to work very well (it's very fast) but I have one small issue, I dont get a HDD activity light - any ideas?

[djos]

Man, that is another beautiful system you've got there.  Just add an Indivision and you'll be all set, although after that then you'll probably want a PCMCIA network, and USB, and...  

Re: your question about the hard drive light, seems pretty common.  Here's one link that might help you:

PS - I sent that link with the cool shirts to my girlfriend, said "if I only had an awesome girlfriend like this guy's awesome wife *hint hint*".  I'll probably be sleeping on the couch tonight, ha!

Cheers mate, looks like i'll be modding my cf adapter tonight!

Yeah an Indivision sure would be nice - might just stick with my GBS for now tho. I aleady have a pcmcia wireless network card (netgear) - just need to spend the time to get it working.

hehehe, nice one, hopefully your GF takes the hint and doesnt get mad at you.

Well that was pretty simple, turns out mine is reversed as others have found here:

but the fix is just as simple:



and the result, all 3 lights now work!

Last night I finally got around to modding my A520 for S-Video using these instructions:

http://members.iinet.net.au/~davem2/overclock/a520.html

Completely disassembled with 99% of components removed (I missed 2 resistors @ R15/16 that I later removed):


I found one major diff on mine and that was mine was missing thru holes for R18 so I just soldered the resistor onto pads that matched up with the right tracks R18 would have used - I did make a mistake in this pic, one of the wires is soldered to the wrong point and as a result I only got Luminance & no Chrominance until I found and fixed it.


Mostly finished (havent mounted the S-Video connector in the case yet):


Hmmm, no Red's! - I suspect it's corrosion in the DB23 causing the issue as the rca jacks are badly corroded and before the mod the colours from the composite connector were pretty crap too:




btw, Considering I no longer have a 500+, I really should get this thread renamed "My Amiga Adventures"!

[djos]

Finished it off this morning:





Just need to fix that missing red issue now.

[djos]

yes, as I mentioned above it worked but the colours were screwy too (missing red).

[djos]

Cheers mate, I'll try that

[djos]

So it really didn't work :p chip could be bad?

try replacing the three electrolytic caps in a row, should be one for R,G and B

The closest resistor size I have to the original 22uF 16v units is a 47uF 16v - I dont know enuf about caps, can I substitute these?
