My SE/30s are very ill. Stock PSU issues, mostly. They’re recapped, but their +5V rails are too low. I might try tweaking the voltage pot - but +12V is already quite high.

As I recall, anecdotally, they got worse after recapping. The big cap is a slightly different capacitance than the original, I hope that didn’t mess things up.

I didn‘t change the big cap..

Have you played with the pot yet? I’ve been putting it off as it’s a fiddle to do, but I need to try.
I might regret this purchase lol

On a Macintosh restoration journey!
Anyone know anything about this mystery USB Port '0' on the Yosemite board? (Next to the firewire module)

The Yosemite schematic says J18 should be a test point for the 14MHz clock going to the IMI SG500 clock generator, so the silkscreen for a supposed USB port seems unrelated. There is mention of a removed internal USB port during the prototype phase in the schematic changelog, so it may just be orphaned silkscreening for that.

That’s interesting!

yeah, agree with @obsolete and @Daniël - that's definitely an RF connector footprint of some description, probably is an SMA but I'm not familiar enough with 'em to be able to tell them by sight so I'll trust @obsolete on this one :-D. No idea what the usb0 silkscreen is doing there.
Hit 94.7MHz bus speed on the Beige today, it’s stable but the clock generator can’t seem to handle more. I have some ideas to push it further.

I want a PM6100 now. :D
Hello--I was seeing some posts about PB100 batteries that you were making. Is that still something you have available? I would love to have a battery for my PB100. Thank you!

Making them is kind of a pain... But yes I sell them on Ebay.

Thank you--I actually ordered one from you yesterday. Looking forward to receiving it, but I understand if it takes time to make it.
Thanks again!
