Some cards are meant for continuous, sequential writes, like cards meant for video capture. I wish there was more information about what's specifically different about them, since long, sequential writes isn't quite the same as simply lots of writes, but I suppose it has to be at least a little...

Yeah, it all depends on what you want it to do. If you want simple and fast enough for 98% of m68k Mac things, then a SCSI2SD is perfect. I just wish we could buy some more v6 ones now. AmigaKit says they'll be back in stock on 19-March-2019, (which is ten days before Brexit - I hope that...

Actually, all of these motherboards which have two SIMM slots support one single bank SIMM and one dual bank SIMM, so you can have a 64 meg SIMM and a 128 meg SIMM, plus the four on the motherboard for a total of 196 megs.

It's possible to swap boards, but chances are it won't work. The factory-made defect list is usually stored in flash memory on the controller board, and that defect list is much more important than later remapped sectors. If you try, let us know of your results.

You're not wrong, Gorgonops, about 68 pin adapters being more awkward, but sometimes they're advantageous because 68 pin cables are easier to route. A quick look on eBay show lots of SCSI 68 pin to 50 pin adapters for $12 to $14 USD. There are even the very short ones which are small enough...

Actually, you have that backwards. The SCSI2SD will likely be faster than most old SCSI drives, but any modern-ish IDE or SATA drive will be worlds faster than a SCSI2SD. I have several ACARD SCSI-IDE adapters with IDE-SATA adapters in all sorts of various machines. They'll do an honest 80 to...

The QuadDoubler / Quadra Overdrive only runs the processor at double speed when the bus relinquish signal is active. This way, literally everything that happens while the '040 is interacting with the motherboard happens at standard speed so there are no incompatibilities, and when no bus...

IDE to SATA adapters work well. I use them in all sorts of machines, and I even use them with SCSI to IDE adapters. IDE to SATA adapters generally run at up to 133 MB/sec, and with a modern SSD, everything feels very fast. I have yet to find any issues with SSDs on older machines, even Quadras...

FYI, "warm" in the context of electrical parts could be the difference between room temperature and, for example, 140 degrees Fahrenheit. Whether room temperature is 50 or 80 degrees Fahrenheit only changes the amount of warmup time, not necessarily whether warmup will happen or not. Do you...

hfsutils works, but it doesn't mount a filesystem in to the normal filesystem space of the OS. It virtually mounts the HFS volume for use by its own tools. This is fine for occasional use or for automated use, but can be a little tedious since regular scripts need to be modified and you can't...

SoftFPU doesn't help with systems which were never supposed to come with LC040 CPUs. Installing an LC040 in a Quadra 700, for instance, will get you a bomb. Newer machines like this one used updated 650 / 800 ROMs, and those supported LC040s. I think the issue is that something in the 660AV's...

I ran first the 700 MHz version, then the 1 GHz version for a total of 15 years with years of continuous uptime in a 9600 running NetBSD. Interleaved memory is fine so long as the memory is fast enough, and if it runs well with a 450 MHz G4, then the bus is pretty certainly running at 50 MHz and...

A good way to stress test a system is to compile. You could install NetBSD and compile a few things from pkgsrc such as perl, Apache, php 7.2, MySQL 5.6 and so on. Compiling is a good test because it requires everything to work aside from video memory - one bit wrong from disk or memory, and...

The Quadra 630 motherboard which has one SIMM slot can take a 128 meg SIMM, for a total of 132 megs of memory. Any of the "DOS Compatible" Quadra 630, Performa 630, 631, or 640, or the LC 631 should have two SIMM slots. These can take one single sided (single banked) SIMM, up to 64...

What brand of SSD are you using, Bubheart'sDaddy73? I've used Samsung and Patriot SSDs connected to SATA-IDE adapters connected to a Quadra 630, to SCSI-IDE adapters, then to an Amiga 1200, to a Quadra 605, and to a VAXstation 4000/60. Never a problem. You are using Drive Setup, correct? You...

SATA-IDE adapters work well, too. I've used a 2 TB drive, just to see if I could, and currently use a 250 gig SATA SSD in a Quadra 630 type system (Performa 636? 640? Whichever one had two SIMM slots and could take up to 192 megs of memory).

Here's information about changing the clocking on an LC III from 25 to 33 MHz: http://www.applefool.com/clockchipping/lciii.html

2 TB definitely do get 100 to 200 MB/sec, but 30 to 35 MB/sec actual filesystem transfer (not benchmark transfer, which might just be reading or writing in a tight loop) on a first generation PCI Mac is pretty good, especially considering that the memory bus is so slow. I've seen and used...

The first photo appears to be correct, but cropped. I've used many adapters like those. Even the cheap ones seem to work just fine at high speeds (100 MB/sec). The mirrored drive door G4 systems can handle drives of any size. They're not limited at all to 128 gigs. Edit: I looked at those...

We really need to find a source for schematics. I've been wondering about bringing PowerPC Mac minis to 2 gigs, too...
