How the hell do you remove the '040 from a Rocket Stage II ? 😳

I bookmarked your article a while ago. But I’ll have to wait until I get a microscope and the appropriate soldering tip. :)
The 33MHz '040 is rock stable at 50MHz in the Q700 with QuadDoubler by the way. (y)

Don't worry about a microscope or fine soldering tips for that mod. It's all normal scale stuff, not fiddly. I don't have a microscope and you could do that mod with a 5mm tip iron (not even exaggerating).

Great, will try soon then :-)

I acquired a busted tray loader iMac. Battery had leaked and destroyed the motherboard. The display, though, I'm unsure and think it might still work. Since these used the DB15 Mac monitor connector internally, what are the chances of shoving my LC475 in there somehow. I know about the oddities around the specific refresh rates. But, would it be worth pursuing, or not bother? The display might not even work.

Sounds not unlikely to work. Maybe you need to use two video adapters in series (Mac to VGA and VGA to Mac), maybe also not..

Let's give it up for Lee Felsenstein's Osbourne 1 which turned 45 on April 3rd. That's right, in 1981 this featherweight 25 pounder ushered in the mass-produced portable computer!

If the apple headphones are 3.5" and not lightning, I'd actually use them with my newly restored iPod 4th gen

The Apple phones work fine on my iPod touch. I also have a set of black headphones that don't appear to be Apple. They also work but sound tinny compared to the Apple set.

I like the sound quality of the Apple ear buds. I just would like to use them with a 3.5” standard headphone jack, so if that’s what they are I’ll take them.

Yes they are standard headphone jack. Where do I send them?

New visitor. A parts dual 867.

The case design is actually quite logical and well engineered but it’s crazy just how much they’ve hacked this case design about to beef up airflow. I think someone must’ve been panicking about the amount of heat the 7455s put out.

Hello there !
I've been using Macs since 1999. Always looking for the latest and greatest tech but just got interested in reliving previous experiences with Apple hardware. Don't get me wrong, the latest Mac models are great, but kind of miss that soul previous Macs had.

The Meanwell RPT-60A is just too tall to be a safe fit in the LC 475 power supply's chassis... The two heatsinks touch the top housing's edges even if you try to insulate them by brute force, and I'm afraid if I leave the top off instead, it's just going to short against the case's RF shield.

I actually mounted it with little brackets to the side. The stand-offs were just spacers.

Oh, right, I saw yours while lurking the thread with the RPT60-A builds! If I had access to more than basic soldering/crimping tools, that'd probably be a much nicer way to go about it, especially since then you don't have to run jump wires for the two chassis/safety grounds.

I fixed the insulation issue with HS1 hitting the safety ground in a way people familiar with this will either love or hate. Since the printed base is too thick and makes it impossible for any joints to touch the chassis on the bottom, even under extreme pressure, I just took the existing, plastic insulation layer and flipped it upside down. Knocked it, pushed on it, tilted it, no fuse explosions, no live chassis.

@Chuckdubuque : Cray-1 IT staff (mostly plumbers) all smoked in the 1970s.

@ClassicGuyPhilly I didn't really grasp the Cray-1 architecture up until a couple of years ago. The architecture diagrams I saw in the 80's implied massive execution unit parallelism, but primarily it's a large register cache with a pipelined EU for each Vector and some scalar opcodes (with chainable operations across EUs). https://www.chrisfenton.com/homebrew-cray-1a/

@Snial I'm glad you have such a firm grasp...you have quite a challenge ahead of you homebrewing one of your own. ;)

That said I'm seriously considering having a set builder make me a full scale replica for my living room which could be broken down for rentals

OK, so if you could pick a set of 8 vintage Macs for your collection (68000 to G5, desktops/laptops/servers), what would they be? I've deliberately limited it to 8 to force hard decisions ;-) !

Hi, Well I would say ... SE, SE/30, Quadra 700, Iici, LC III, LC 475, iMac G3 and PowerMac G4 AGP.
