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 -...

Methinks the problem lies within the funky Gazelle architecture, not power issues, hence that firmware upgrade. Problems with FireWire bridges and my no longer supported TEMPOtrio abound, the Alchemy architecture was solid at its 40MHz bus speed. G3 L2 accelerators and combo cards were devekoped...

Thanks for the input. I saw a similar TAM upgrade using the 6400/6500 riser almost twenty years ago. Interesting that he's using USB and SATA cards. I've got a SATA card ready to go, but I've been using a USB card for the diagrams as that's what folks expected to see five years ago. Ideally...

Last pics for the day: Mock-up in my 6360 with Sonnet Tempotrio in the top/setback slot. Card isn't supported in the funky Gazelle architecture of the TAM/5500/6500, but docs say Alchemy Macs are supported. USB, Firewire and faster ATA/133 bus all on one card. Slot connector is spaced .2"...

No doubt there, good results have been achieved with all kinds of crazy concoctions/methods . . . given enough experimentation. No fuss/no muss has a quality all its own. ;) Hopefully this is the original formulation? It's branded with the trademarked name. ISTR RetroBrite was originally...

Parallel Developments: TAM - Internal PicoPSU - AUX Power for Expansion Slots TAM - Fatback - Printable copy & FatterBack maximum expansion Mod of baseline model? Cardboard template development, close approximation achieved I think: Baseline TAMtent w/ Rage128/DVD Daughtercard TwinSlot...

From the pics I have on hand, in terms of size the two(?) parts seem easy enough to be printed? Repro FatBack would seem to be in some demand I'd think, many are missing and unavailable in the wild? FatterBack version would bow the curve of the hump out a bit - providing more overhead for...

Cooling in a TAM will be the sticky point, don't have one, but tinkering with a FauxProtoMac counterpart. Maximum Power spec for expansion cards in 6500: PCI Expansion Slot - PowerMac 5500-6500-DevNote The main logic board uses the industry-standard peripheral component interconnect (PCI) bus...
