Eight slots means you can have up to 8 gigs of memory. It's not all that picky, but I've found lots of older memory which won't properly run at the full 400 MHz. Considering how cheap the memory is these days, though, you should be able to get matching sets for really not much.

You can use any disk formatting software with SyQuest, but if you use the wrong kind, it won't necessarily support changing cartridges properly without restarting. The SyQuest extension will poll the drive for disk changes.

I have a few machines which are running off of +5 and +12 volts. The only thing that doesn't work is the sound.

My kitty will volunteer one for you. If you have a good thermometer, measure the idle and busy temperatures of the CPU before you replace. I got a few m68040s which were supposed to be the newest mask which got just as hot as an old early 1990s mask before I finally got a real new one.

The only time I've seen caps affect speed is when the SCSI bus was affected and got lots of errors due to capacitor problems. I couldn't see any issues in Mac OS, but in NetBSD I'd get SCSI errors in a constant stream. Recapping fixed the SCSI, and disk access went from painful to what we...

There's only a 2 TB limit. While the SCSI chips support drives larger than 2 TB, the limit comes from using just 32 bits worth of blocks (four billion 512 byte blocks). SCA isn't a problem so long as you get adapters with high line termination, like so...

Welp. I tried on my LC II, too. I even found a monitor adapter with switches, set the screen depth to 1 bit, and removed the VRAM. I get the grey screen and that's all. The machine boots, but I can't see anything. While looking for the monitor adapter with switches, I came across a 512K VRAM...

Just posting for future reference. I eventually got everything working on a 250 meg CompactFlash card in the PCD-50B by using a SCSI2SD set to the same number of sectors as the CF card. For some reason, the CF card in the PCD-50B fails when I try to initialize it using Drive Setup or HD SC...

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 never heard of issues with different masks of m68881 or m68882. From where did you get the impression that it might be an issue?

Very, very interesting... I just recapped an LC II board and tested it with VRAM installed. I'm going to give it a try without.

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...

I'm pretty sure that's the case...

I seem to remember that any model less than 6400 should be fine. A 6400 or higher model motherboard will have a 3.3 volt line which would end up getting 5 volts if put in to a Quadra 630 case. A Quadra 630 motherboard in a 6500 case might short the power supply's 3.3 volt and 5 volt feeds. If...

Keep in mind that many PowerPC cases will put out 3.3 volts on one of the pins, so don't plug in a Quadra 630 motherboard without checking pinouts first...

I've bought several m68040 / m68060 CPUs which were supposed to be the latest mask. Each time, when I've identified them as older, re-labeled CPUs, I've gotten a full refund and haven't had to mail back the CPU. I think most people don't check, or they think they're getting a CPU that should run...

A 128 meg SIMM will definitely work in a Quadra 630.

The LC475 can take 64 and 128 meg SIMMs just fine. I think the idea is that the IDE Quadras only have four banks of memory total, so one bank is the 4 megs on the motherboard, the other is the single bank SIMM socket, and the other two are the dual bank SIMM socket.

When I found a bunch of 128 meg SIMMs on eBay for $8 apiece, I bought a bunch because they'll definitely work as 128 megs in dual bank slots and as 64 megs in single bank slots. Sometimes it's better than trying to find the right kind of 64 meg SIMM.

He he he... Probably. But the list is growing :) https://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/m68k/8.0_2018Q4/All/
