In every instance since the late 1980s, CPUs are faster than memory, which is why the CPU speed is decoupled from memory speed. But using one clock base to drive memory and CPU jus…
The processor card is what determines the system bus speed.

That's backward, isn't it? The system has to be in-time, and that's given by a master oscillator …

My only experience is with the Crescendo Nubus G3 cards and the automatic configuration of their …
That's backward, isn't it? The system has to be in-time, and that's given by a master oscillator crystal to which the memory and processor must obey. In Apple IIs and the early Mac…
I'd either hang onto it or sell it, definitely don't recycle it...I don't think StarMax's are all that common (well at least they're not here in Australia anyway, none of the clone…
Don't the Sonnet upgrades automatically increase in speed depending on the bus speed? The 7600/120 has a 40 MHz bus, while the 7600/132 has a 44 MHz bus, so I think the upgrade is…
So you have the tower version... Nice. Yes, it's nice to have the ability to use standard, easy to find drives yet still have access to SCSI stuff (like my DDS tape drive).
It'll …
603e processor is soldered to the logic board.
It is a very odd beast, something like a 4400, but with five PCI slots (in a riser card), an SVGA port, both ADB and PS/2 keyboard c…

I have one I found in the trash in NYC in the late 1990s. I installed NetBSD on it and now it does NAT / IPv6 tunneling / DNS / NFS / NTP stratum 1 time / DDS-3 tape backups and ot…
When I first bought them, they were around $150. For a while they weren't available for less than $200, but it seems the price is a little more reasonable now, back to what I paid:…
Ought I to keep the StarMax 3000/200 clone I recently acquired, or offer it up to the recycling gods?
Alternatively, is there anyone here who wants it for a clone collection? It's…

The base reference is a 5400 RPM 300 gig Hitachi HTS54323 2.5" SATA drive connected via an Acard ARS-2000SU SATA to UltraSCSI adapter / case.

I have two LCIIIs, none of them have any wires or anything whatsoever, however they are fairly late model LCIIIs, both manual-inject models, and both with October 1993 build dates.
There should be a reset button on the back.

All I can find is a black stamp that probably reads "9B", a bar code and serial number of sorts "*B13020Q5EN6B* SINGAPORE VAIL", and printed on the logic board PCB "APPLE COMPUTER …
Looking at your pic, it seems clear that the vent holes are not at the highest part of the case, when the Mac is mounted at that angle. Would propping it forward such that the vent…
Check the Developer Notes for each machine, they all have a rough logic diagram, listing the interconnections between the various ASICS, the CPU, what is connected to the Fast and …
I don't even think you can - I don't think the Apple PC 5.25" drive has a port for daisy chaining, does it?

I got a used G3/375 Sonnet upgrade a few days ago and put it in my 7600/132 today and system profiler is reporting a G3 at 417mhz! I didn't know these could be overclocked.
Yep, you're correct. The max number of drives you can get on a Mac is three. Two internal (SE only?) and one external.
