Now I have two #C64 wedge PSUs, both perfectly working.
The one on the right might be a slightly older model, but the specs are the same: 9V AC 1A and 5V DC 1.5A.
Oh, wow! It's one of those older #C64 boards made in 1983, assy no. 250407!
The SID and PLA are socketed and might have been replaced. Other than this, the PCB looks pristine.
How do I open the RF shield of the VIC-II without wrecking it?
The #C64 which I recently repaired is revision 250425, designed in 1984.
The first thing I notice is that the SID and the PLA switched places on this newer board. This revision also consolidates all clock generation logic down to a single IC: the MOS 8701 right next to the VIC-II.
@codewiz What a beauty!
@codewiz I personally don’t like to use the wedge bricks. I have several. They give me the heebie jeebies. If Commodore didn’t pot everything into resin one could service them, but alas…
@root42 I bought a RetroPower PSU for the Amiga, thinking it also had the 9V AC output for Commodore 8-bit machines, but... nope
If it can't be modded, I'm *not* buying another expensive variant of the RetroPower. Which PSU would you recommend?
@codewiz I know that there are differing opinions about them, but I only had positive experiences with PSUs from c64psu.com
They are based on regular Meanwell supplies and also provide the 9VAC. Yes, ripple is higher than on old, non switching power supplies, but in the years I have been using them I haven’t had issues yet. If you plan on using lots of expansions (REU etc) make sure to pick a beefier variant.
They also have variants to power both a C64 and a 1541-II at the same time.
@root42 If only they came in a proper shade of beige!
@root42 I don't understand why nobody is selling a single PSU with 5V, +/- 12V, and 9V AC.
The RetroPower came close, having a unified DIN connector on the PSU side and adapter cables that can be purchased separately for each computer model.
@codewiz That is a thing of beauty
@codewiz Did this come out of a pyramid or something?
@slyborg It was shipped via Poste Italiane in 1983
@codewiz I hate to be the one to tell you that you got scammed, but that C-64 may not be new
@codewiz Nice... Amiga 4000
