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!

Odds aren't good given hard to find parts but gonna try...

Ok..hmm. :) I'll ping you once I get to the point where I need new new ones :)

Well, after recapping everything, it powers up to a blinking green light and then eventually a solid green light. I then believe it attempts to print a test page and the printer comes to life, but then it stops and the red jam light goes on. It feels like it's unable to suck in a page from the paper cartridge. Will need to debug further when I get some more time.

Hi Max1zzz,

I also am quite interested in the SCSI Card for The Rocket. Can you be so kind as to inform me when these will be ready for purchase next month?
Thank you for making these SCSI cards available to us Mac IIci Rocket owners! 😎 Very Cool Indeed!

Probably in the next month or two, the SCSI chips are on their way to me right now and the PCB design is done, just need get some PCB's produced and order the rest of the bits :)

Beige G3 running a 87.3MHz bus. :)
Swapped out the reference crystal.
ASP still thinks it’s 83.3.

@Snial I wonder how it’s doing it’s memory performance calculation.

Theoretical maximum is one thing, i don't think I've ever seen even 200+ in Gauge Pro. I'm unsure what it's using to calculate either.

"moving memory" = moving from one memory address to another = 1/2 the speed. If you add latency (333) you can subtract at least 50% again. Then there is wait-states from the controller, CPU and software induced (read-write cycle ... maybe with crc-check). The potential 266MiB/s memory (moving) throughput will more likely be maximum of 133MiB/s. Typical is about 1MiB/s per MHz so 87MiB/s would be considered normal.

I was able to fit a Cabletron Ethernet NIC into the SE FDHD - a bit tight with two floppies and an HDD in there. Had to cut some sheet metal from the HDD tray to get sane clearance. This was my final goal for this restored Mac, but after years of using it with serial PPP, it's fun enough with Ethernet that I may reconsider parting with it. :)

Coming right up! I'll have it open again b/c I have decided to try and fix the very slight jitter on the video. Why not go for 100.0% restored? 🤓 The parts (NP cap, diode, transistor) arrive later today.

Me complaining about my Beige G3 23 years ago lol

I really wanted to like Mac OS X when it came out, but I couldn’t. It took buying my first MacBook Pro in 2007 to properly feel comfortable with it.
