I'm curious what's in yours now and what other card you'd install if you had a second slot available? ATM I'm experimenting with a USB card and a Rage 128 Pro pushing 1920x1080 out the back along with the onboard Video in my 6360. Prototype TwinSlot cards still need a bit of tweaking, but...

Hi, Joevt, hoped you'd join in here. Just rebuilt the TestBed and have successfully tested 6360/6400 boards but haven't located my 6500 board. I'd though I might have corrupted my CF boot disk, but it was the reader that died? My first thought was that there might be some machine ID setup on...

I've got a test rig that'll boot Alchemy and Gazelle boards, but not my AIO 5500 sub-variant of Gazelle. Does it fail to POST due to lack of internal CRT hookup or might there be another issue with this particular board? If display is indeed the problem, will it POST with the external...

That's what I'd figured, but thought to ask. Thanks!

Might the 5300ce be using the 1400 ROM to support its 800x600 panel?

Yep, what a wonderful world of Apple's approach to things. If you've already got PDS equipped form factors in production, just use bailing wire, chewing gum and duct tape to shoehorn something that doesn't really fit into it in a way that would make Rube Goldberg look like a strict follower of...

GREMLINS! Got it to boot up in both slots without problem. I'd reinstalled the backplane plate to the card, but it wasn't screwed down properly/firmly, which probably caused some stress between card, riser and logic board connector.:oops:

Sonnet Tango 2 is a combo USB/FW card incompatible with TAM/5500/6500 Gazelle architecture machine unless the fix is applied. It should be good in my 6360 and 6400 Alchemy architecture machines, along with the 5400, which I'm happily not dealing with ATM. Why is it preventing full boot and...

It's Alchemy Architecture, not Gazelle in which this card is problematic without the Great Gazelle PCI Fix. Makes no sense to me unless some PCI equivalent of DeclROM in a NuBus Mac is present? Any suggestions?

Here we go: Dunno, my money is on PSU-C being my 6360, just a hunch based on differences/improvements? I think I need to trade for another working 6360/6300, too many Logic boards on hand,. Thankfully I have the front shelf from my Q630 stripped of its MedusaMess which is in a...

Thanks, what are the identifying characteristics? I'll get the pics posted of the other two this afternoon. __________________________________________________________________________________________________________________ Teaser: Official announcement after all kinds of testing complete...

PSU_A - Can it be identified from these pics? Any other method? Need to take better pics of PSU_ C & PSU_D FAN threw Autofocus off badly.

Thanks very much, put some work into it and sharing some of the pics I've collected over the decades. I've never seen a serious discussion and nary a mention of cooling in the Compacts outside of stories of SJ's vehement opposition to best practices for such approach to engineering the 128K...

No swivel feature, but the raised height/angled ergonomic correction provisions would have alleviated many of the 128K Mac's packaging, neck fatiguing and inexcusable design sins. I've always wondered why every known ZFP Case is flat on top? Angle the b***h! I've long been treasuring a 17"...

Deletion of the Twiggy drive in 128K prototyping with substitution of the Sony 3.5" FDD was the root cause of a multitude of cooling/longevity issues for the Compact series.** Sheet metal enclosure on the Shugart 5.25" Drive Mechanism***** based Twiggy drive created a chimney effect...

Been studying up on the TAM, It's appear to be a stock 5500 board, the only difference (but for ID resistor setup) would the unpopulated SCSI port connector. SCSI devices internal and external DB-25 port are connected through that crazy I/O daughter board at bottom that hides the missing...

I think that I just put put in a "request from supplier" for purchase of an MC68020rc33 for $15.00? Ebay is $40-50, surprised I found any of them available at all from anywhere.! Wondering if the timing GAL setup in the the Performer we've cloned might be convinced to clock double 68020 to...

I hope they taped the vents at the top of the bucket closed! If not the fan's just sucking air in from them, down, back and right out. Close the vents and it'll be cooling the logic board by air in from the vents front-n-sides like it was supposed to be cooled by convection. If you tape it up...

Did a more refined diagram in AI8: In parallel TD thread, It came up that USB-C can only output one voltage at a time. But the little Power Converter/Power Supply is the only powered device and only pulling one voltage from USB-C, so it should be continuous? Pathetic TAM PSU is on its own in...

. . . hopefully! Start of this project was info about the anemic TAM PSU issue from many sources, here, Tinkerdifferent, WWW and ThinkClassic back in that day. Was working on putting together a better Initial Post, but what the heck . . . just chuck it out to the pack of wolves! :p...
