hardware revision 1.11
1NetBSD/mac68k _VER runs on several of the older Macintosh computers. 2About 4MB of RAM should be sufficient to boot, and the system can probably 3be squeezed onto a 40MB hard disk by leaving off an unnecessary set or two. 4To actually do much compiling or anything more interesting than booting, at 5least 8MB of RAM and more disk space is recommended. About 75MB will be 6necessary to install all of the NetBSD _VER binary system distribution 7sets (note that this does not count swap space!). An additional 25MB or so 8is needed for the binary X11 distribution sets. Much more disk space is 9required to install the source and objects as well (at least another 300MB). 10 11 12Supported models: 13 14 Mac II, IIx, IIcx, SE/30, IIci, IIsi, IIvx, IIvi, 15 Performa 400/405/410/430, Performa 450, Performa 460/466/467, 16 Performa 520, Performa 550/560, Performa 600, 17 LC II, LC III, LC III+, LC 520, LC 550, 18 MacTV, 19 Centris 650, 20 Quadra 610, Quadra 630, Quadra 650, Quadra 700, Quadra 800, 21 Quadra/Centris 660AV, Quadra 840AV 22 23 24Supported devices on all of the above systems include: 25 26 Onboard SCSI bus and most SCSI tapes, hard drives, and CD-ROMs 27 Internal sound--enough to beep on some machines, anyway 28 Most basic NuBus video cards (there have been some 29 problems with some 24-bit color cards and with most 30 QuickDraw acclerators) 31 Both internal serial ports 32 ADB keyboards and mice (both Apple and a number of third party 33 multi-button mice and trackballs are supported) 34 Ethernet cards based on the National Semiconductor 8390 and the 35 SONIC (DP83932) chips 36 (Asante, Apple, and a few others--problems still 37 with Ethernet and many NuBus video cards) 38 Onboard Ethernet based on the SONIC chip for Quadra-series Macs 39 Onboard Ethernet based on the MACE (Am79C940) chip for the Quadra 40 AV-series Macs 41 Comm-slot Ethernet may be working for some machines/cards 42 43 44If your 68030 system is not listed above, it may be because of a problem 45with accessing onboard video, and it may still work with a serial console. 46Some of the known ones in this category: 47 48 Classic-series Macs 49 PowerBook 100-series and Duo-series Macs 50 51 52If your 68LC040 system is not listed above, it is due to a problem with 53floating point emulation (FPE) for this type of processor. Machines in 54this category include: 55 56 Newer LC-series machines 57 Newer Performa-series machines 58 Some PowerBook 500-series Macs 59 60 61What isn't supported, but often asked about: 62 63 Macintosh IIfx: This machine has unusual custom chips for the 64 ADB and serial interfaces which make support for it 65 difficult. Work is in progress on this, though. 66 Quadra 900/950: These machines have I/O processor chips for their 67 ADB interfaces similar to those used in the IIfx and thus 68 face similar support problems. 69 PowerPC-based Macs: This will be a separate effort from the mac68k 70 port. The PowerPC is a much different processor as is much 71 of the hardware inside these machines. If you are 72 interested in this, you might want to take a look at 73 http://www.mklinux.apple.com/. In addition, there is 74 also a NetBSD-powerpc port. For more information, please 75 see http://www.tools.de/~ws/NetBSD/powerpc.html. 76
