My experience with the Beige G3 is that the stock hard drives are slow as molasses. The built-in IDE bus is only 16.7 MB/s (whichever ATA that is) but the hard drive doesn't even perform up to that level--at least mine did not. Once I installed a more modern hard drive (faster media rate, i.e. faster data from platters to heads) the machine showed a marked improvement in performance. Beyond that, you can easily spend more upgrading than a faster newer machine would cost you on the used market. That said... A faster IDE card would improve things as well. Acard makes a very nice two channel ATA-133 card however, it will set you back about twice what you paid for the machine. Some years ago VST Tech sold an ATA-66 card based on the Promise UltraTek 66 card. If you move three or four SM resistors, possibly pull the half-size metal can oscillator (there are different versions of the UT66 and some have the Osc. and others don't) and desolder and reprogram the Winbond Flash chip, you can convert a cheap (<$5) Promise UltraTek66 into a VST UltraTek66. If you care, I'll try to hunt up the conversion instructions. The Promise cards were apparently OEM in DELL machines or some such, so there are a bunch of them on the used market. The bus speed and bus-CPU multiplier are controlled by a jumper block on the front left of the motherboard. You can change the bus speed >from 66MHz to 75 (IIRC) or 83 MHz by moving jumpers. However, many of the Beige G3s won't operate at 83 MHz and tests show that this doesn't really make a big difference in performance. The 300 MHz CPU can often be run at around 366 MHz, so you can speed your CPU a bit by changing the bus-CPU ratio. Many folks have done this reliably, but my experience was that it caused problems after a while. CPU replacements up to 1.1 GHz are also available but the manufacturer's (PowerLogix) retail outlet (OWC, macsales.com) seems to be out of them. See above about spending more money than a newer used computer would cost... There's a gap in speeds between 500 MHz and 900 MHz having to do with the version history of the PPC750. The machine used PC66 SDRAM but PC100 or PC133 will also work. DIMM capacities up to 256 MB are supported but some addressing modes are not. So you need (I think) 16 chip DIMMs on the 256 MB capacity. IIRC eight chip 256 MB DIMMs will not work or will only be seen as 128 MB. 512 MB DIMMs won't work because of limitations of the Motorola/Freescale MPC106 memory/PCI controller/bridge. For the things where my memory is hazy (indicated by a ? or "I think") check the articles on G3 computers at xlr8yourmac.com. Also, there's a link from the FAQ there to the jumper settings for the Beige G3 motherboard clock and ratio settings. >I don't care for the Mac monitor that came with it--has anyone tried >hooking up a fixed-frequency SOG workstation monitor to it? I've got >a nice HP/Sony model that might be a candidate. Mac DB15 to VGA adapters are common and cheap (=<$4, I sell a multi-rez model for $4 shipped in USA). If the monitor will work with a VGA output, it should be possible to make it work on the built-in video of the Beige G3. However, the Beige G3 and earlier Macs rely on sense codes in the monitor cable to indicate what resolutions are supported. When an adapter is used the sense codes are provided by the adapter. Some adapters are fixed-resolution coded so it's tough to get anything but the adapter's fixed resolution out of the Mac if you use a fixed resolution adapter. Other adapters are "universal" and have DIP switches to support many resolutions, and one of the resolution code choices is "21" multi-resolution". Jeff Walther

microprocessors in my vax 3800

by vax9000＠gmail.com

Today I pulled out the boards in my vax 3800 and I found 7 microprocessors besides the CVAX. They are, 2x 68000, 8096, 80186, 2x 8086, Z80. Just a little discovery to share with you. vax, 9000

The later Revision 2 and >3 use Rage Pro. Thus, I think the video issue you're noticing is probably >the accelerator. The original 300 is almost certainly Revision 1. The video chip can be visually examined, although the "Wings" card (AV card) may be in the way. It will have Rage II or Rage Pro (or Rage Turbo?) printed on it. You may also be able to get this information from Apple system Profiler in the Apple menu. If the ROM DIMM has not been switched out, you can determine your revision by looking at the ROM revision in the first page of Apple System Profiler. Under "Production Information" look at "ROM Revision". If it is $77D.40F2 then you have a Revision A ROM. If this ROM shipped with this motherboard then you also have a revision 1 motherboard. However, the ROM DIMM is pretty easy to switch so there's no guarantee that the machine contains the ROM it originally shipped with and all of the ROM revisions work with all of the motherboard revisions. If the ROM revision is $77D.45F1 it is a revision B. If it is $77D.45F2 it is a revision C and absent ROM swapping the machine probably has a RAGE Pro video chip. If you have a Rev. A ROM, then the built-in IDE channels in the machine will only support 1 device per channel. You need Rev. B or C ROM for two device support per channel. You can also determine your ROM revision by looking at the Apple part number on the two ROM chips on the ROM DIMM. However, I don't remember the numbers. It's something like 341S0409 and 0408 is Rev. A, 341S0494 adn 0495 is Rev. C and I've never seen a Rev. B with the part numbers on it so I can't say, but I imagine it's 341S04xx with xx up close to 90. No matter which motherboard you have, switching to a B or C ROM will enable two device support on the IDE channels. >You might as well get a Rage Orion and I think you'll find the performance >much better. The Rage Orion is a 16MB Rage 128 PCI card, and I know from >personal experience that it is Mac-compatible and has good performance. >They're pretty cheap on the used market. Rage Orion was ATI's name for one of the Macintosh versions of the Rage 128. PC versions of the Rage 128 won't work. (I am not contradicting Cameron, just restating his information a bit.) It may be possible to do a conversion from PC version to Mac version, but I don't think anyone has ever reported a successful modification. The Radeon 7000 works well in the Beige and the Sapphire version of the PCI card with DDR memory is easily converted to Macintosh use. It is also just $30 at Newegg. Simply remove the eight pin SOIC serial flash chip and replace it with a blank ST Micro M25P10. It should then either flash with the current Mac firmware updater from ATI or it may require the R7000-ROM-208 version. It's been a while. I know the latter will work. I'm not sure about the former. Whichever way, update to the latest firmware afterwards, because there are some Sleep issues with earlier versions. 3D driver support is only official after OS 9.2 but if you install the Open GL 1.22 or 1.24 extensions by hand into OS 9.1 it works fine.

We're talking about two slightly different things here, though- 68000 (while it did not have provisions for easily running 6800 code) had a common-mode so that programs built on the 68040 could run on the 68000, but you can also have code that requires instructions (or other things) added on later 68000-series processors, similar to Intel (variable 286-style segments, the copy-on-write provision of the 80486, etc.). The transition between 68000 and PPC was more like the Intel gap between the x86 and the 960 - they are completely different processors with no common heritage (the common heritage piece was provided by Apple in firmware). I haven't worked with them, but AFAIK the new embedded versions of the 68000 (ColdFire?) maintain the tradition of working with earlier 68ks (except in a few cases).

The software probably can work just fine at 68040 speeds, but then when run on PowerPC systems you have the emulation overhead which drops speeds to around a IIci (25MHz 68030, think Sun-3) on a 8100/80 (80MHz PPC601) Some companies didn't want the bother of maintaining two versions (68k and PPC, especially after the PPC machines had been out a year or two), so they would compile PPC only- hence the higher system requirements.

Sorry, but I think it's the worst designed robot in the history of films! Robbie the robot (Forbidden Planet, 3 or 4 eps of Lost In Space 60's tv series, background in Gremlins 1 (or 2?) and even in a Columbo film >from the 70's!), Gort (Day The Earth Stood Still), Maximillion (The Black Hole) and more modern robot's such as Robocop, ED-209 and Caine (all from the Robocop films), plus the T-1000 (Terminator), are much better designed to be menacing and/or cool looking. When I saw the one from the Lost In Space film (from 90's) I just laughed. To be honest, going from the picture, it looks like a cross between the robot's from Short Circuit and Caine from Robocop 2.

One had the giant holding a boulder above his head with John and Don below him and the other one was a 6" (or thereabouts) tall model of the Robinson robot. Not sure where they are now though.
