A few people have asked how I make use of modern SCA SCSI disks with older machines.
Since high end 10000 or 15000 RPM 3.5" drives are overkill speedwise, and since most of us don't really need 300 gigs on our older machines, I've settled on 70 gig 2.5" disks such as the IBM 90P1316, the...
Although on the Amiga, this is impressive:
I'm sure some enterprising programmer could take this port and bring it to m68000 Macs. It's amazing what these old machines can do!
I recently recapped my LC III motherboard and it works wonderfully. I had an extra m68881, but it's only rated at 16 MHz and the LC III is running at 33 MHz, so I decided to buy a faster rated m68882 from eBay for $6.
I've gotten lots of fake m68040 and m68060 chips from eBay, so I was a little...
Many older NuBus / LC ethernet cards work fine with 100 Mbps and gigabit switches with auto negotiation. However, certain cards seem to not want to work. Some have a jumper which causes the link to stay on regardless of the physical connection.
Does anyone know how to make these cards work with...
After seeing mention about how the LC and LC II can do monochrome video when no VRAM is installed, I tried it. It didn't work. Then again, my multiscan adapter only works with my LC II in 512x384 mode. So, even though the machine booted, nothing beyond the boot grey appeared on the screen (the...
I've got an LC II motherboard which Brett B. kindly sent me. It needed a good cleaning and recap, and now it seems to work. I connected the PCD-50B SCSI card reader that I use with my Quadra 605, and although the LED flashes shortly after power on, it won't boot.
It occurred to me that the SCSI...
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...
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...
Does anyone know of a reputable seller who has L88M mask m68040 CPUs for sale? I really want to finish my Quadra 610 - it has a NewerTech Quadra Overdrive, but it isn't stable with the CPU it has, so I'd like a CPU I know will work.
The last one I bought from "u-barn" on eBay was counterfeit...
There's lots of talk on this site about how cool it would be to see this project or that project, but none is as exciting as a project which could ridiculously speed up our current m68k Macs. Some of us have been following the work of the folks who are making an FPGA replacement for the m68000...
I thought this was an interesting discovery, so I figured some of you folks might like to know.
For ages I've used SCSI-IDE and SCSI-IDE-SATA adapters on various m68k Macs. I just had a 2 TB drive fail in a Quadra 610 so I decided to replace it. One of the spare drives I have lying around is a...
I started an archiving project using a Mac Quadra 610 here:
https://68kmla.org/forums/index.php?/topic/25007-starting-archiving-project-using-quadra-610/
However, the 50 MHz NewerTech Quadra Overdrive proved to be not all that stable. The rest of the machine is 100% stable running at 25 MHz...
I've seen plenty of threads over the years about various web resources and sites disappearing. People put up mirrors, but sometimes those disappear, too. I decided to do something about this.
I'm putting a 2 terabyte drive in to a Quadra 610 which runs NetBSD. On it I'll host and mirror...
In Apple's official documentation and other documentation on the Internet say that the Xserve G5, which has eight memory slots, can take up to 16 gigs using ECC memory. In the past I've bought a couple of 2 gig ECC DDR-3200 DIMMs, but they didn't work. Considering how some regular DDR DIMMs...
Neat article about BMOW's writeup about a rewritable ROM based on work from Rob Braun and Doug Brown:

Hi, m68k users!
I've been using bbraun's djMEMC fix in the NetBSD kernel to support 260 megs in a Quadra 610. However, sometime between last summer and now I've noticed that when I'm booted in to Mac OS 8.1, the Quadra is showing 132 megs whereas it was definitely showing 68 megs in the past...
Flash versions have been growing like crazy lately. It seems that the modified Flash version which gave PowerPC users some respite is now too old for certain sites. I've updated the Flash plugin to report itself as version 16.1.102.64. This, I hope, should last a few months.
Get it here...
Someone decided to put together a parts list and 3D printer files for a compact Mac based on a Raspberry Pi and Mini vMac:
https://learn.adafruit.com/mini-mac-pi/
While the resolution of the screen is only 320x240, it scrolls so it can support a higher resolution. The screen is color and the...
There has been much discussion about ways to get CompactFlash cards onto SCSI busses. Some machines can take a full height 3.5" drive or another option is putting something in place of a CD drive, so SCSI-IDE adapters like the ARS-2000FU (which mounts underneath an IDE drive and makes it full...
