1NetBSD/pmax _VER runs on the following classes of machines: 2 - Decstation 2100 and 3100, also known as "pmin" and "pmax" 3 - Personal Decstations (5000/20, and /25) also known as "MAXINE" 4 - Decstation 5000/120, /125, and /133, also known as "3MIN" 5 - Decstation 5000/200, also known as "3MAX" 6 - Decstation 5000/240, als known as "3MAXPLUS" 7 8NetBSD/pmax _VER does *not* (yet) run on these machines: 9 - Decstation 5100 (an r2000-based cousin of the Decstation 3100) 10 - Decsystem 5400 and 5500 (Qbus-based systems, similar to 11 a Vax 'Mayfair' and 'Mayfair II', but with an r2000a or r3000 12 cpu instead of a CVAX cpu.) 13 - Decsystem 5800 (xbi-based multiprocessor, a Vax 8800 with 14 Vax CPU boards replaced with Mips cpu boards) 15 16The minimal configuration requires 8M of RAM and ~60M of disk space. 17To install the entire system requires much more disk space, and to run 18X or compile the system, more RAM is recommended. (NetBSD with 8M of 19RAM feels like Ultrix with 8M of RAM.) Note that until you have 20around 16M of RAM, getting more RAM is more important than getting a 21faster CPU. 22 23Supported devices include: 24 Decstation 2100 and 3100 baseboard video: 25 pm one-bit mono or 8-bit pseudocolour fraem buffers. 26 27 Decstation 5000 series TurboChannel video: 28 PMAG-DV Personal Decstation baseboard 1024x768 frame buffer. 29 PMAG-BA 1024x768 8-bit colour frame buffer. 30 PMAGB-BA 1024x768 8-bit colour frame buffer. 31 PMAG-AA 1280x1024 four-bit greyscale frame buffer. 32 33 NOTE: All supported DECstation vide produces sync-on-green. 34 Be sure to use either a DEC-compatible fixed-sync monitor 35 or a multisync monitor that supports sync-on-green. 36 37 serial ports: 38 ttya and ttyb (can be used as console if needed) 39 40 ethernet: 41 on-board AMD Lance ethernet ("le0"), 42 TURBOchannel AMD Lance ethernet cards. 43 44 SCSI: 45 on-board DEC "sii" SCSI controller (2100 and 3100) 46 on-board "asc" SCSI controller (5000 series machines) 47 TurboChannel "asc" SCSI controller, 48 DEC (LK-201 or compatible) keyboard 49 DEC ("hockey puck" or compatible) mouse. 50 51 52Hardware the we do NOT currently support, but get questions 53about from time to time: 54 Q-bus Decsystem machines 55 Decstation 5100 machines 56 PrestoServe NVRAM on Decstation 5100 machines 57 audio drivers for Personal Decstation machines 58 floppy driver for Personal Decstation machines 59 TurboChannel audio hardware (LoFi) 60 PMAG-C 2-D accelerated framebuffers with onboard i860 processors 61 62 NOTE: the primary obstacle to support of all but the very 63 last item is non-availability of sample hardware for development. 64 65 The primary obstacle for the i860-based framebuffers is that there 66 is no documentation on the accelerator board. 67
