    Designing a portable RAM card

    The Mac LC should be your inspiration because this is exactly what Apple did with it: The LC has a 16-bit bus and it's running a '020.  On the PC side of the fence Intel released the 386SX which was the low cost version of the 386DX.  The 386DX had a full 32-bit external bus and the 386SX had a...

    Nobody likes the G3 all-in-one

    The all-in-one Macs are generally my favorites but the G3 AIO is one I just never could appreciate.  Some of them, like the TAM grew on me over time and the one in my collection certainly gets a lot of "what is that?!" reactions from people who are not so computer-savvy.   The fact that the G3...

    Store demo disks?

    I have a collection of maybe 100 or so, from the 1980s Macs up to the G5s.  I should probably make a website. They are very hard to find because Apple demanded that they all be destroyed after the machines were out of the retail environment. I have managed to find quite a few that I had no...

    Can this be done? PPC upgrade on 6100?

    No.  The right-angle adapter is required for the DOS card to work because has custom chips that pretend to be an '040 CPU.  100% of the data that comes into or out of the 601 PDS and the DOS Card is translated by the adapter.   The same thing happens on the LC PowerMac systems.  They have a...

    Can this be done? PPC upgrade on 6100?

    Bad idea. The '040 uses a 32-bit data bus and the PowerPC 601 uses a 64-bit data bus.  Usually the PPC upgrade cards had a large amount of cache (1MB or so) to offset the slow Quadra RAM.  Taking that into consideration, the whole purpose of the PDS adapter for 6100 was to make the DOS card...

    Max Drive Size for A/UX?

    Got it, thanks! Apple's own docs mention enormous drive sizes but I figured it would fall short of the theoretical limit: http://support.apple.com/kb/TA40318?viewlocale=en_US&locale=en_US

    Max Drive Size for A/UX?

    Hi all, What is the max drive/volume size for A/UX? I expect that there will be limitations on the Mac partition and boot partition but can there be larger "storage" volumes? Any special considerations? Thanks

    iMac Colored Accessories

    Yes! I remember those and I was actually looking for the lamps and figured they would be a nice compliment to a fruit iMac. I was having a lot of trouble finding them and finally found out why...

    iMac Colored Accessories

    In the late 90s there were many fruit iMac-inspired color products and accessories. Some came in a couple colors from the factory (like the Handspring Visors) and some had swappable covers (like the Epson 740i). I am looking around for some "matching" items for fruit colored iMacs but most of...

    Dark spot on 850AV monitor

    A few years ago I was lucky enough to buy a NIB 850AV monitor from a parts dealer on eBay. The video and sound from this monitor are both truly spectacular with one little issue: there is a dark/discolored spot at the bottom-right of the screen. Degaussing using the built-in setting doesn't...

    Questions about WGS95 and A/UX

    Agreed totally. A key reason I am willing to use the WGS95 for this is because it won't be online 24/7 for the exact reasons you mention. I only plan to have it online when I have one or more vintage Macs running and they need to talk to mass storage. There may be a week or more stretch where...

    Questions about WGS95 and A/UX

    Awesome. Thanks for the correction. :) I will look into that. I am also going to read through the Classic Mac Networking Guide and think about this stuff. It's interesting that the printer adapters never mention any of that in the documentation. Why is that? Is it like the Apple thing...

    Questions about WGS95 and A/UX

    Ah, I didn't explain the 2GB limitation. I'd like to be able to mount some of the shares on the old Macs which would certainly be pre-OS 8. That's why I mentioned the 2GB limit. Even though AppleTalk would officially support it, OS 6 or 7 won't. Disappointing, but not surprising. Should I...

    Questions about WGS95 and A/UX

    Actually Apple says that it is: http://support.apple.com/kb/TA29581?viewlocale=en_US I can see the concern. Since my project doesn't involve a multiple user setup I wasn't as concerned about that part. I did figure there would be some stumbling but considering the slow connection I was...

    Questions about WGS95 and A/UX

    I need some advice from the A/UX masters. I've found an awesome use for my WGS95 and A/UX ... as a fileserver and bridge machine for my the classic Mac network I am finally building out. I do have a few questions though. The old Macs will be on a LocalTalk network (ranging from PhoneNet to...

    Tape Drives and Software

    What software (other than Retrospect and some A/UX stuff) can take advantage of tape drives on an old Mac? (This includes the Apple Tape Backup 40SC and the tape drives built into the WGS systems.)

    HPV vs. NuBus video?

    What type of VRAM do the HPV cards accept? Any Apple 68-pin 80 ns VRAM? (Like the type that was used in the LC class Macs?)

    HPV vs. NuBus video?

    Sorry if this has already been covered, but ... Which is faster? The High Performance Video PDS card or a NuBus video card? If NuBus is faster, what level of QuickDraw acceleration will overtake the HPV card? I realize that the HPV card is just a super-fast frame-buffer with dedicated VRAM...

    Please help with iMac G4

    The backlight is working properly. The screen lights up normally but remains a light gray with no image. (It is the same shade of gray that usually appears with the Apple logo.)
