Since the processor is located on a daughter card, I would assume yes.

Well if 7.5.3 runs about as fast as 7.1 on the Classic II, I may just have to give it a go. The key attraction for me would be the better AppleScript. Maybe the best thing would be to do a fresh installation and try to use it with System Picker, so that I could revert to 7.1. The minor...

You have the required terminator on the end of the internal scsi ribbon cable, right?

Yes, I like a Classic II as well. For certain uses, like pure word processing, it is a fine machine, which carries out its duties with a minimum of fuss. But System 7.5.3? Why, oh why on a Classic II? Mind you, I have a vague recollection that the blessed eQuill, formerly of this parish, used...

Surely that .455kw would mainly be spent on spinning disks and fans, comparing numbers at a furious rate, and generally running the thing — generating heat as wastage in the process. How many watts would be wasted as heat is a guess, but the machine isn’t a simple resistor.

A Quad at full load apparently consumes 0.455kw/hr. If we assume for argument’s sake that 100w of that is dissipated as heat (which I expect is an over-estimate, but whatever), you’d be talking about it providing 2.4kwh a day of heating. So maybe you could actually take the edge off the cold...

There’s an optical sensor in both my (earlier, I think) Turbomousen which has to be clean; there’s also a capacitor, so you know what that means by this stage. Both mine had problems moving the cursor in one direction. One got fixed, and the other needs to go back to rehab, I’m afraid.

Switching processors would require thermal recalibration, but it ought to boot with fans blasting after the switch if the processors are both working. Sounds like a serious hardware fault.

A bad job of applying heat sink paste could give that result. The G5s are hard to get right — I have done the job often, and have needed to repeat the process two or three times over the years because of high temps after the first go. So it might be worth pulling it apart one more time….

The eMate battery is easily replaced by buying one of these (or higher mah capacity), snipping the leads off a couple of inches long, and soldering on the wiring from the original battery...

It does not require a IIfx, no. I think much of the association with the IIfx is that the 24GC so nicely complements the co-processors/ controllers unique to that machine, in the 24GC’s having not only a Quickdraw processor but an actual operating system that boots up, running the Nubus card. A...

Cameron Kaiser. His name leapt to mind just as I pressed the post button.

As I recall, the fellow who developed TenFourFox had IIci cache cards fail regularly in a machine used as a server of some sort running 24/7. I think they may well be prone to failure, but if it turned out just to be two caps, well, that would be a good thing.

I think the Thunderstorm is just a DSP card, so no video out, but an interesting card for image work in a IIfx. Can’t comment on the others, except that none are especially high end.

Maximizing your RAM would open up interesting possibilities for booting and working from a RAM DISK, via Maxima or the like. Combined with memory compression software like RAM Doubler, it would then be possible to have a really large RAM disk in the Q650, allowing you to work from more or less...

I have recently moved and much of my mac gear is in storage. I still have a couple of machines handy, however, one of which is a Classic II. For reasons that need not detain us here, it happens to be a favourite. Now, it has not been used in a while. Last time I tried it some months back, it...

Sorry about that. That will teach me to rely on what I call my memory! It has been a long time since I touched the old gal, but i just dug it out to check. Shift-Fn-Ctrl-Power is the reset combo, apparently. I DO remember having to reset the machine occasionally, however, and that my backup...

Tried pushing the reset button on the back? Anything is possible, of course, with dying components et al., but the Wallstreet in my long experience of it (I used one as my main laptop for several years) was a model somewhat afflicted by GLOD. So yes, the backup battery (it’s not a pram...

I still have it (Spectrum 24/ V, as I recall), but we moved across the country last year and my stuff is still in storage, some of it being rather deep in storage, so I can’t really answer your question, Trash. Sorry. I am going to start excavating said storage and selling much of my old Mac...
