The World's First G3 Swapped TAM

[@dosdude1]

This was definitely a sweet upgrade to perform! Hopefully I can resolve the weird cache card upgrade extension issue. As for OS X, you’ll definitely want to connect an external display, especially during the installation, as Open Firmware does not show any video at all on the internal display of that machine. Once the installation is complete and you select the correct display resolution, in theory, OS X should begin working on the internal display. Also, when you install, ensure that OS X is installed onto the first 8 GB partition of an IDE drive, otherwise it won’t boot.

[@DGgraphicsNY]

Amazing!! You are the man.

[@LovelyAlanna]

Hello, I'm curious, what is that lamp thing you used to heat up the chip to be able to remove it? I've never seen one of those before

[@sjgrall]

I knew the G3 was based on the 603e, but I didn’t know it (740 specifically) was “pin” (ball) compatible per se…fascinating. If only my soldering skills weren’t awful….nah, I’d just use an upgrade card

[@LabCat]

Shenanigans like this are a breath of fresh air for those of us who grew up in an era of "Why not? Try it and see if it works" hardware hacking and computer modding. I don't even think that you'd be able to do the same thing between, say, an M1 and an M1 Pro (although it'd be awesome if you could).

[@boomers_pb]

M1 to M2 or M1 Pro to M2 Pro seem more likely, the die carriers between the Pro and base M series chips are a different size. Knowing Apple, they probably move around data and power balls just to fry anyone's hardware who attempted such a thing.

It amazes me how flexible macs can be with CPU upgrades.

[@raven4k998]

or the g3 is compatible with that old cpu in terms of the socket

[@tomshotdogs6645]

This is what makes it so frustrating to me that Apple takes such a strong anti-consumer, anti-repair stance. If I could just swap parts out when they break; or just.... run the code I would like to run on my devices without the machine fighting with me... I'd still be a dyed-in-the-wool Apple user. Hell, even now, I just got an M1 macbook by chance; even with all the frustrations I have with modern Mac OS, there's a lot about it I REALLY like... It's just that the stuff I don't like is so unpalatable, I feel bad using the thing.

[@johntrevy1]

@@tomshotdogs6645 The only problem I have with the AS systems are the soldered storage. For those not made of money and prefer Apple you are essentially forced to use an external storage solution to extend the life of the machine.

[@ZeroHourProductions407]

@@johntrevy1 it feels blatant, that apple went with arm specifically to spite the hackintosh movement, where it was possible to use AMD CPUs and have a resulting build that performs better. That and time and again, arm silicon can't multitask to save a literal life. Source: every phone, ever.

[@johntrevy1]

@@ZeroHourProductions407 In today's energy crisis it makes sense to go with ARM. ARM is rapidly catching up with X64 in performance. As regards to the Hackintosh, well Apple sort of created it in the first place.

[@RetroHoosk]

My experience with the XPostFacto 'bricking' the 6400/6500 (and I imagine the TAM due to its similarities) is purely because OpenFirmware on these machines defaults to using the serial port, you have to set XPostFacto to use the keyboard for input and the internal video for output manually.

[@danielnesbitt9565]

I have run OS X 10.2 on my 5500/225 years ago (it was painful) and IIRC you need to enter a few commands on a seemingly blank screen (the OF prompt sets the screen brightness insanely low for some reason). The version of OpenFirmware used in these series of Macs is apparently buggy too.

[@LightTheUnicorn]

I love how unique and characterized your various machines have become, from the misbehaving clones to the cursed SE/30 and now the absolute chaotic beauty that is the TAM G3. Totally wild, love it!

[@10MARC]

It's interesting that almost the entire market for accelerators on modern machines has totally dried up. I suppose in theory people still upgrade their CPU's directly, but going from one generation to the next with a card is just not done anymore. Modern computing is rather boring, actually.

[@common_c3nts]

[@wallyhackenslacker]

At this point that poor TAM is probably the single most frankensteinian beast ever shown in this channel. If it hasn't surpassed the Cursed Macintosh in quantity and drastic-ness of upgrades already then it's still giving that one a good run for it's money. I would never have the courage to try and mod a machine this much!

[@jaybutler]

It was great to meet you at VCF and to see some of your machines.

[@2dfx]

Not surprised that the CPU swap performs better than the cache card seeing as the cache card is ultimately going through a separate translator/multiplexer which will ultimately hamper performance. The cache card upgrades were always a bodge.

I'm impressed that you have taken mac modding to this level. I'm a bit dismayed in that Wolfenstein 3D and Doom ran 'buttery smooth' on my old 386DX way back in the mid 90's. They should be running on any PowerPC processor like effluent off a soil removal implement. I'd love to find out why this is. Is it that Mac OS just isn't game friendly in how it allows games to get to the hardware? Lazy programming? Might be an idea for a future video.

[@monkeyman767]

It's the first one, certain versions of Classic OS just don't support the calls properly and are translated instead. There are later versions of doom that run flawlessly but there's no real way to identify what version is what, they look the exact same

I remember getting 10.2 running on a Powermac 6500/225 way back in the day. It worked, but it took 10-15 minutes just to boot. I imagine the slower, unsupported architecture and the paltry 128MB of RAM had something to do with it. I think I had it booting up faster on old 604-based Macs.

[@georgesenda1952]

Is there a West Coast equivalent to the shows in Chicago and where you went to ?

[@Nymunariya]

I wonder if the OS X not booting/installer not being happy is due to the list of acceptable macs. That reminds me of e trying to install Jaguar on unsupported macs. There is however a special version of Jaguar 10.2.7 for iMacs that might not check the model id? I'm pretty sure I used that to install Jaguar on a G4 MacMini. That could be worth a short, but IIRC the 6500 and TAM are still old world. So maybe it should be the same process as getting OS X on your beige G3?

[@pmc_]

IIIRC, at least with Leopard, you can edit a plist somewhere in the installer to make it ignore the supported system list. But if anyone can figure it out, it's probably dosdude1 himself - he maintains patchers for more modern macOS versions to allow them to run on older systems than technically supported.

It has always struck me as a little funny that Jobs hated this machine so much yet the design cues are very evident in Apple products even today. Clearly the designers thought more of it than he did.
