Lots of activity on the PSU front for 6500 recently and in the far distant past. Some 14 years ago I was looking into 6500 and Beige G3 ATX conversions. Going for an ersatz TAM/FatBack form factor build now that will be powered entirely by the 250w PicoPSU pictured above. In his discontinued...

Indeed! Love your work. Thinking you could cram your design into a lower version of TAM/CSII riser's form factor? Looks simple enough in terms of parts count. Pigtailing the board to a panel mount connector for the backplane opening allows all kinds of tomfoolery! 😀 Not to mention opening your...

Top View of same, 6360 is great, can still use the CSII NIC along with the additional PCI TwinSlot gambit. A USB WiFi Thimamajig attached to a powered hub, fed from the pigtail should be something like 10% better throughput than the CSII 10bT card, no? TAM Tent Template shows the CSII...

Trying to keep things as simple as possible, I sourced a six inch right angle FW M->F pigtail cable to match to the 12 inch RA USB M-F pigtail cable on hand. Looking at my original TwinSlot Riser setup, I'd figured a setback increase was in order. Experimentation proved that an additional .3"...

Hearing mention of vestigial implementation on the 230 board for the second serial port just now blew me away! How much higher throughput might that Printer Port(?) connection have than the Modem card interface? Thinking it might put an entirely new spin what I recall as a Modem WiFi card...

OMG!!!!! @This Does Not Compute enough with the tease! Is it the tablet or do you have a specific Duo schematic? 😀

Glad you guys like it! Did you get a load of my matrix test bodge? 🤪 Hoping somebody will wed that table/switch matrix to a USB KBD controller at long last. PiPortable hybrid is an obsession awaiting retirement, which will be a year or two off.

Thanks! Interesting, but don't think it's the Beige G3 DT PSU, as it's listed at 230 W maximum continuous in the ServiceSource. I'll have to pull my 6500 PSU apart to compare the innards to those pics. Makes no sense to me, but maybe Apple really did do a custom PSU for the TAM? If so, my...

Yep, thanks! It shows the flange reinforcing/supporting the fan side of the PSU can. Does air enter the surround at the top and then is exhausted out that vent at the back of the surround? Hinkiness if so! I see a nice chunk of the 150 W available power never makes it down the supply cable to...

Looks like you're probably right. Development was hurried, so they must have used the already UL approved 6500 PSU? What a kluge! :rolleyes: My 150 W 6500(?) PSU looks a lot like that picture. Only the A/C passthru for display connection is missing. Looks like the metal housing is enclosed...

Thanks, I'll mock it up and post pics. If any TAMs reside within an hour or so from Raleigh, NC or are in the D.C vicinity between June 12 and June17th I'll be up there for a bit.

Is anyone in the U.S. interested in doing the physical/fitment testing the cardboard prototype for me? No harm can be done by my paper/cardboard doohickey. pm if interested. ;)

Can anyone take some pics from the "inside" of the FatBack with a card and its PCI riser bolted up to the slot cover for me? Clearance measurements between the top of the stock riser and inner surface of the lid would be a huge help. This is about the only time I've ever been interested in...

Hrmmm . . . how much does the CPU actually do while communicating with a network? Your posts, especially that video, have me energized to take the physical experimentation cardboard mockups to fruition. I'd love to send that guy a riser that interfaces correctly with the fatback slot cover's...

Thanks! Forgot all about that fix! Saw it and commented on it in January '23 and then promptly forgot. I fell off both forums for quite some time, just getting back into things here and there and digging back into this project for R&R. Interesting commentary in that video: The lack of slot...

According to everymac L2 G3 cards were released between 1/4/99 thru 11/1/01 for different architectures. January 4, 1999 - https://everymac.com/upgrade_cards/sonnettech/crescendo_g3_l2/crescendo_g3_l2_225.html January 4, 1999 -...
