I'll ignore all the rambling about what's on topic and what's off topic and assume that on topic means anything referring to a RAS hack for Quadra 605 / Performa 475 motherboards. The djMEMC in the Quadras 610, 650 and 800 supports up to ten banks of memory, each being up to 64 megs. This means...

The controller supports drives of any size. The original iMac only supported booting the OS from within the first 8 gigs of a disk. Later slot loading iMac G3s can boot from anything within the first 128 gigs. In order to use larger drives, you need Intech's SpeedTools ATA Hi-Capacity Driver...

The internal bus will only ever do a maximum of 10 MB/sec. I have a Power Mac 9600 with an ATTO UL2D which regularly got 30 to 35 MB/sec with a 2 TB SATA drive on a SATA-IDE adapter, which was on an Acard 160 MB/sec IDE-SCSI adapter. The same setup gets upwards of 80 MB/sec in an Alpha machine

I'd be interested in three sets, possibly more.

You can download any version of NetBSD back to 1.0 here: ftp://ftp.netbsd.org/pub/NetBSD-archive/NetBSD-1.6.2/mac68k I bet you can still easily compile 1.6 on a modern system...

Real-time bitbanging in this case may be faster and easier using the PRUs on a BeagleBone.

Boot to Open Firmware by holding down command-option-O-F while powering on. When you get to the Open Firmware prompt, try: eject cd

I think horizontal sync and video get inverted and vertical sync goes straight through. All you need on the 9 pin for the monitor is: 1: ground 7: video 8: horizontal sync 9: vertical sync No idea where you get the signals from on the Plus, but that shouldn't be hard to find. Ground any...

Back in the early 1990s someone gave me a Mac Classic with a (physically) broken screen. I found and ordered a new tube, but that came in the mail broken. So, instead, I built the motherboard in to a little PC tower case and made a TTL adapter with just a 74LS14 (Schmitt trigger inverter). I...

It seems that none of my Centris and Quadra era machines are stable anymore unless they've been recapped. In the last few years I've recapped several motherboards, but even they started showing issues, so now I'll be recapping or replacing power supplies, too. After recapping my 1U Amiga 1200...

It was cheaper, and it only speeds up things that can use it. All non-floating point stuff runs at exactly the same speed whether an FPU is installed or not. Since many Macs were used for graphics and desktop publishing, FPUs were quite helpful.

Happy holidays, 68KMLAers! I have a nice Quadra 605 motherboard which I've recapped and did the resistor change to run at 33 MHz. Partly since the plastics have become so incredibly brittle, and partly because I don't have the capacitors needed to recap a power supply, I've decided to build...

If you haven't recapped your machine and power supply, it's probably time. I haven't seen any '030 that hasn't needed new caps yet. With regards to BSD, cross compiling a kernel is completely painless. There's a kernel configuration file called "SMALLRAM" meant for a Mac with 8 MB or more. If...

I started writing to say that I don't think I'd still have binary packages from so long ago still around (and I still doubt I do), but then I looked around... At very least, I still have NetBSD 4 sets for mac68k which are compiled with softfloat and therefore don't need an FPU. Also, on an...

I have a Power Mac 9600 with 1.5 gigs of memory running NetBSD. It has been quite useful as memory usage with php under Apache has ballooned over the years. I can't think of another computer from the mid 1990s that could take as much memory or could take accelerators up to what's available for...

I remember Slackware on floppy from the '90s. I don't think any contemporary GNU/Linux is going to support floppies, but pretty much all Unix-like OSes support rooting your filesystem anywhere that the kernel can see. A cross-building environment will be... Interesting. But you talk about...

For the most part, yes. You can use drives up to 2 TB. I've tried > 2TB drives in a Quadra 630, and they do work, but I couldn't find software that allowed me to partition the disk properly. Most standard SATA drives with SATA-IDE adapters will work. The CompactFlash to IDE adapters depend...

What's really cool about the older iPods is that people are almost throwing them in the trash when the battery and/or disk die. A new battery off of eBay or Amazon is usually around $5. A CompactFlash to iPod adapter is usually less than $10. When my 60 gig iPod Photo's disk died, I got both...

Considering you can get a USB-C (Thunderbolt 3) to Thunderbolt 2 adapter and a Thunderbolt to Firewire adapter, and a Firewire 800 to Firewire 400 adapter, it'll work fine. My Firewire iPod has no problems with Sierra. Hold on - there's a Macbook with USB-C which ISN'T Thunderbolt? That seems...

While I love the Apollo / Vampire FPGA accelerators for the Amigas, I think this would be more useful to more people. Since the FPGA wouldn't need to support video emulation and all that, perhaps it'd have enough space for a full CPU, with MMU and FPU, and could be a 100% compatible drop-in...
