Not a Macintosh SE build

[Trash80toHP_Mini]

I'd say that's almost certainly a 640x480 capable 9" or 10" Mono CRT and its neck board. The A/B for it is clearly located on the left side wall of the case I think:

I have a color 10" CRT installed in roughly the same manner with protruding tube tail/neck board and its A/B installed in a Classic in like manner.

edit: I've tried to get the pics above to display here, but it seems opening the links in a new tab will have to do. Does anyone know how to get an attached image from same or another thread to show up as the image intended rather than a link?

Speaking of color CRT in compact... in 2005 I looked for a color CRT that would fit, actually wasted money on 3, always 2"-4" too long. I thought it was impossible. But I found this link in another 68kmla thread.

Project Mac SE Monitor Mod

geektechnique.org

So there is at least one model of color CRT that will fit without protruding.
I can't tell what make or model that monitor is. I tried the contact, it's undeliverable. Anyone know what that is?

Nope, from the "internals" pics it's pretty clear that the CRT in that mod protrudes from the back of the case as well. Camera angles conceal the protruding neck board just about the same distance as in my ongoing project.

The only way to get a 10" color CRT to "fit internally" is to hang a reproduction of the form fitting "BacPack" HDD enclosure off the tail end of a Compact case. Even then the neck board won't fit without creating an offset version of the neck board dropping it lower and to the side in order to clear the chamfer angle matching "roof" of the HDD case extension.

If you want to explore this approach to fitting one of your trio of misses, start a new thread in Hacks and I'll post more pics. Proposed high voltage transfer neck board device might work for the CRT, but would surely be very efficient to the touch.

I didn't see it before. That page is snake oil.

I would consider some other 68k Mac logic board, but as far as I know, there is no other 68030/40 Mac logic board that will fit that is superior to the SE/30 logic board (that takes a decent amount of RAM). You can't fit a Quadra 950, 800, or 700 logic board in a compact Mac, and the other smaller Quadra or LC logic boards that might fit, such as the Quadra 605, use the 68LC040 processor with no co-processor. One option that is attractive, that possibly could be shoehorned, perhaps vertically, is the LCIII+ logic board... but bare classic Mac logic boards aren't usually readily available, and I do not want to cannibalize any viable classic Mac.

The Quadra 630 is far superior to the SE/30 and fits within the confines of the Compact footprint. You can transplant a full 040 into the LC/Performa versions. Maximum memory capacity has been an ongoing subject for the series. All models output 640x480 and 800x600 VGA resolutions for native LCD support. PC compatible versions you might find particularly interesting.

Another member and I have done this installation, his was right side up within the Compact case and mine has a two slot 6x00 board inverted with a ZFP HDD case sub-basement for housing the protruding second PCI card underneath with PSU.

Quadra 630 consideration leads me to think Mystic, then to LC 575 with swapped processor. Sometimes a logic board is available, but there's an underlying brutality to this kind of hack. There's compelling economic reasons not to destroy the OEM machines, and there's other good reasons, too, and I'm not sure I'd want to participate. I like the 575, and I'd really like to have one, but I've worked with similar platform; they're great, but they're big furniture, not fun to move around, less fun in plural. Someday, tho.

Sorry, you're thinking there is running hard up against the sea change that was the Quadra 630 architecture. You're grounding yourself upon the shoals of LC5x5's video system's utter incompatibility with the modern world. Not to mention running straight back into the arms such a build's antiquated SCSI HDD interface and generic expense of putting any modern solid state storage on it.

Q630 and its lesser (some better) offspring give you VGA/SVGA compatibility and dirt cheap IDE adapters to solid state devices. Such a build can be entirely reversible. The original, storage friendly Q630 form factor's housing beats that of an elephantine eared LC5x5 AIO monstrosity hands down I think.

You were thinking Pi, don't think any farther back than the Q630 as both can easily coexist on an A-B switch setup within.
