MB-6582 mk2 optimized power supply confusion


MD

Recommended Posts

I am having confusion about the optimized power supply..... I havent ordered any parts for my mb6582 yet (figured id research first ) but i am hitting a big wall trying to figure out where the mods on the c64 psu go. Pictures of the main board PCB indicate to me that they do not happen on the board and i find the schematics I have found searching the forums very straight forward as far as components used ( diode bridge etc) but vauge as far as position in the physical makeup of the box. I want to do this as cleanly as possible and what I neeeeeeeeeeeeed is a picture of how this is done in the construction. If I am wrong (if it is on the top right corner of the board where the core section is) id like to know and id also like a close up of that section. I am obviously about it so ANY help would be great thanks.

I'm not sure exactly what you mean by "mods on the c64 psu".

Do you mean:

1. how to configure the PCB to be either 9V only or 12V/9V (i.e. PSU Option A and PSU Option B)

2. the first run of PCBs which expected 5V supply on one pin, but some C64 PSU transformers output 5V on a different pin

If it's #1, that's in the documentation.

If it's #2, that was fixable in the revision 1 boards by soldering a wire across two pins of the socket, and fixed in revision 2 boards.

Note also I have been very lazy and not updated the documentation with PDFs of the latest PCBs. There are only a couple of minor differences.

There's no mods to be done to the C64 PSU.

You don't need pictures, you need the pdf that you can find on the wiki.

I downloaded and read the pdf here http://www.ucapps.de/mbhp/mbhp_8xsid_c64_psu_optimized.pdf before asking this question....The PSU options are very well documented and talked about all over the forum (thanks) I was just wanting to see it in more tangible form and was kinda curious about the 7809. But after I posted this i realized that the c64's i got off ebay dont come with psu's so! onto option D.

P.s. thanks for the replies on this

p.p.s wilba is a bad mofo

I am realizing that more and more as i look at the pcb PDF. I suppose I could just buy another c64 with a PSU. I would REALLY appreciate a close up pic of how this board gets power ( call it a wet dream i just want to see it). I have a lets say....good understanding of electronics i went to school for it for 2 years and i have lots of building experience from robot kits etc. This is just a little looser than that and i just dont want to get anything wrong.
