According to the CW documentation, selecting 68881 for floating point should generate fpu instructions on a 68040. There are two codepaths you can follow to compile for fpu, either by using Metrowerks' math.h or by using Apple's fp.h (a comment in math.h says that using fp.h is not recommended...

I need to correct my previous post, it is in fact a 7500 in my cube, not a 7000...

The graphics card in a cube is in a really confined space and does not get good air flow so it gets real toasty, you need to keep that in mind. My cube has a 1.2GHz Encore which actually runs quite cool and quiet with it's little 80mm fan, and I settled on a Radeon 7000 for the graphics card...

I didn't realise until working with mine that the 840av was sold with both tray and caddy loaders, so it would be potentially possible to make one out of two and have the bezels wrong. I'm 99% sure the tray loader will not pass through the opening of the caddy loader bezel... Edit: sorry I...

I haven't got one of these to try, nor ever tried with a Mac, but on several other scalers I've used for other purposes, bridging the single video output across all three inputs results in nice clear white on black...

Same here, even though I bought it second hand on a tight budget and it was pretty old by then, my 7100/66 took me through university - and countless hours for my flatmates and I playing F/A18 Hornet.

I vaguely remember installing MkLinux on a 4400 way back when both of those things were fairly contemporary. It definitely worked as I used it for a little while. The 4400 has the same graphics processor on board as the Mach64, so that would suggest that it's not the video card...

Are any of the Quadra pds slots not on the bottom? Wombat is certainly that way but idk about 900/950? Cable routing is not any easier on the 800 style case, there is no access window at the bottom of the drive cage where it would make sense. So you have to fold and shoehorn the ribbon in...

Possible. I wonder if cables/connectors interfere with the lid?

How so?

Updating this for the sake of accuracy as I revisited it this evening. I guess I never had this fully compiling before, although it does now and runs with exactly the same output as the VS original. The parameter typing was my misunderstanding/misreading the compiler errors. The real issue was...

Yes, I didn't consider that option!

Maybe I'm not understanding your logic, but the plus (and I'm pretty sure the SE and Classic too) uses a 16mhz crystal and halves it for the cpu. The performer can just use the raw clock for 16Mhz no? For this to run at 12Mhz would require a 1.3 clock divider to be implemented on those pals...

Considering the significant differences between 68000 and 020, and the large numbers of pluses probably still in inventory at this point in time, it seems that this would be a very viable method of getting 020's into the hands of developers (internal or external) in the run-up to the II...

So there is, thanks for the tip!

I havent tried variadic macros, but some limited testing indicates that compound literals work fine, as long as "ANSI Strict" is turned off... for example, both of the following compile and run: struct Test { int b, c, d; }; void output(struct Test a) { cout << a.b << " " << a.c << " "...

That would lend even more credence IMHO to the idea that it's an apple prototype rather than a third party commercially released accelerator... Like I said before, it's definitely not a big mac, but from that folklore article: I wonder if these were a run of developer machines, later than the...

The C++ compiler is always enabled, but it's only used for .cpp/cp files - the option forces it to be always used instead of the C compiler. The option that toggles "future" features is to have "ANSI Strict" turned off, and it is off by default anyway. In my VS 2019 project that I mentioned...

That's not so bad - engineered USW joints generally have a few sharp edges around which to fracture cleanly... I'm guessing on your one it left an easily glue-able fracture line?

Is the glue in these able to be softened with a hot air gun? I have a 5300 psu that I'd like to do at some point also...
