CD32 power supply / compilations info

[chaoticjelly]

Hey guys,

Well I finally managed to get hold of a CD32.. only problem is, there is no power supply!

I thought that I had one kicking around somewhere, but it turns out that the three dark coloured Commodore power supplies I have - one is 4 pin, but SQUARE connector.. and the other two are 4 pin with ROUND connector BUT... they have the pins in a REALLY strange arrangement (I wonder what they could be power supplies for)

I could probably get an old ATX PC psu - but would I have to really mess around to get one to work.. how would I go about that? I read a guide on a website, but it wasnt very clear, would I just make an adaptor from a molex connector to a 4 pin din, and just plug the CD32 in that way?

Also, Im looking for the compilations (100, 200, 444 and any others) does anyone know where I can get these?

I tried ebay and some guy was flogging the 200 compilation, but he wants 16.99 for it and im not paying that!!

Heys CJ,

Before you start plugging in to the mains like mad (although fun can be detrimentus to your CD32), you are however in LUCK as power-supplies are my *ahem* speciality

I will give you a mod that should work with what you have *gonna go through my notes *

[Zetr0]

well i started, googled a pinout, and there somes allready done it lol.

heres a link. http://www.ianstedman.co.uk/Amiga/am..._PSU_to_a_CD32

good luck

[edit]

Btw after reading this is a very good resource, however i have engineered a far simpler way of converting an ATX psu ( you dont need a7474 D-type flip flop chip unless you intend to run a line from ser to ground the +5 and reset the psu) *you can do this hardware to a reset btn*

Thx for the help zetr0

I saw that page a while ago and I was wondering if I buy this here:

300W PC ATX PSU

And i make up one of the adaptors on that site (molex to 4 pin din)

I can just plug the PC power supply into the adaptor via the molex, then the 4 pin din into the CD32, turn on the PSU, turn on the CD32 and away I go? (not in the exploding sense, but the CD32 powers on????)

Please let me know 'o master

Also where can I get these CD images

I only have Chaos Engine and James Pond 2.. good games but I want more

Okay my friend, what you need to do is the following,

*RELAX* and *BREATH*

like any modification clear your mind before continuing, if you are in the least bit unsure take a break and talk with a professional electrician.

once you are read to continue, we are to begin.

use take a 4pin molex from the PSU power supply, you need 1 black(gnd) 1 red(+5v) and 1 yellow(+12v)

attach these according to the schematic, and it will sovle your power problems


as a last note, you will have to connect the green(or brown) PS-ON to any ground(black) on the atx psu, as this turns the power on

then all thats left is to power on your cd32

I got my CD32 hooked up using my spair ATX powersupply I had around by using an adapter cable.
You can find one on ebay that works well, just do a search for "Supply Adapter cd32"

You will need to wire a short-ciruit on the ATX connector between pin 14 (PSU-ON) and ground (black wire)

Thank you guys!!!! I can do this :-)

I'll make the adaptor myself no problem hopefully lol I just hate those damn barbs in the molex connectors annoy me no end..

Tnx for the help, and if anyone knows where to find these CD32 compilations so I have some dam games to play then you'll be a greek god to me!

I made a powersupply for CD32 using the PSU from an old SCSI cabinet. It's much smaller than an ATX supply, and can fit in a small container like those black plastic ones that Maplin sell.

The old c64 Floppy drive power supply works, but i sometimes with serious problems. If you try to switch on the cd32 it takes almost 20 times till it runs.
But after that, it works fine.
