I am only speaking in the case of a system with adequate resources. Of course a system with heavy paging activity will run slowly. That was never in dispute. What I'm getting at is that there is really no rational reason to turn off VM if you have plenty of RAM.
FYI, there is no "map" when the MMU is inactive. There is one "map" shared by all memory address spaces (inverted page table) on PowerPC when the MMU is enabled. In addition, the translation lookaside buffer (TLB) exists to reduce the number of page table accesses by way of caching. Please...
10.1.2 has extremely slow I/O with my Fujitsu USB2 MO (MCM3064UB/DynaMO 640U2 Hyper, Japanese market, manufactured February 2003), 10.1.5 massively improves it. Interestingly, the 10.1.5 release notes specifically mention improvements for users of MO drives. I did discover that you cannot mount...
FYI, it appears that macOS 10.13.5 has no problem reading MOs on a Fujitsu DynaMO 640U2 Hyper USB2.0 drive: https://imgur.com/a/3NP38Cn
Parsing the Japanese-language manual, it seems that this drive is officially supported on Mac OS 9.0.4 and up, including OS X 10.1 and up as well. No drivers...
4500 isn't a bad price. TBH, I'd pay that for one all complete like that. I paid about 3000 for an Olympus SCSI unit with just the PSU, and the same for a Fujitsu USB2.0 unit with the manuals and driver CD, both 640MB.
BTW, other sources for media that I've used are rakuten and amazon.co.jp...
I've looked but haven't found one. Not sure if it existed. I know Logitec (not to be confused with Logitech!) sold them in Japan for the 5300/3400, but not the 1400. Incidentally, Logitec also made MO kits with bezels for almost all of the PMG4s.
Edit: FYI, the going rate on Yahoo Japan for a...
FYI, the trick with HDT is to go into the FWB tools control panel and check the removable checkbox for your MO drive's SCSI ID. This tells it to auto-mount MO media. Had to do it with an Olympus MOS360 that I didn't have proper drivers for.
These numbers look far more reasonable. I always suspected that there was a large gulf between MSRP and street price. This was true for almost every other computer maker at the time.
And I frankly wouldn't be surprised if most of those 10/100 cards were effectively behind a NuBus-ISA bridge, with no streaming burst transfer support. IIRC, your point about Quadras and NuBus 90 is correct. I think only the AV machines actually support it for CPU-card transfers, as opposed to...
I'd like to see some objective results. Can someone time, say, a 30 MB file copy with Quadra onboard Ethernet vs. NuBus 10/100?
The white elephant we're all forgetting is that the classic Mac OS networking stack is not exactly a paragon of efficiency. Speculating over theoretical numbers is...
