  1. Neither of those are Yikes boards.
  2. I had a Yikes motherboard I receieved just to take the G4 zif out of it. I'm pretty sure it uses the exact same IDE controller as the later B&Ws. Apple didn't really change anything on it as it was just a stopgap machine. You won't get the high bandwidth but an SSD is going to be a lot more responsive than an old mechanical drive. I'm pretty sure even that will be noticeable. TRIM support isn't THAT big of a deal from what I've heard. Its helpful but most drives still do their own garbage collection and such.
  3. I believe Zip drives (from what I remember about the earlier ones; click-of-death and such) were somewhat unreliable. I would just remove it personally. Flash/thumb/jump/whatever drives are so much more useable and compatible across machines compared to an 'ole Zip disk. Mind you, you might want to replace it if you're using it to move data between it and an older Mac with a SCSI-based Zip drive. I think (based on my B&W being similar) that the faceplate is held on by clips inside and then the drive slides out the front (once you unscrew it that is).
  4. Hey, I was lurking through e bay when I noticed a run-of-the-mill Beige G3 with an unusually high level of bids on it. I looked closer and I noticed an unusual video card (I assume) in it. Since the seller couldn't be bothered to take any inside pictures (I can't stand that), I only have the ports at the back of the card to go by. I thought it might be the port the SGI 1600 used but doesn't seem to be. Mind you, I'm assuming its an actual Mac card and not a PC one someone just threw in there. I'm just interested because this must be what someone was bidding on. I doubt they just really wanted a Beige G3.
  5. I think the Daystar, along with all the other multiprocessor systems of that period, was asymmetrical multiprocessing not symmetrical (SMP). The list of MP software was short and limited to professional-level software. I think I was reading another discussion on another mac board somewhere. Aside from that, an awesome machine. It just looks it means business. Plus, the processor card itself it interesting to look at. I remember seeing one on ebay many moons ago.
  6. Does anyone have any experience in using the DVI port on an 'ole Radeon to output to to a TV? I used a cheapo-generic dvi-to-hdmi adapter but I'm not sure that's what's at fault. I've heard (I can't dredge them up at the moment) that the original Radeon had some issues with the DVI port (no output, etc.). I did used to have it hooked up via good ole VGA but that's not practical as its on the opposite side of the room from the TV now (I have a tested 25-foot HDMI cable I use now).

    Zif Carrier Advice

    Not to bring up a dead thread, but Powerlogix only sold up to 1.1GHz G3s. I believe if you held down option when opening up their CPU Director software, it would give you access to the higher multiplier settings. You could then overclock it to 1.2GHz or beyond. I actually have some results on Geekbench from when I ran my B&W G3 at 1.2GHz. It would eventually cause issues if it ran at that speed for a while, another one I had would just immediately freeze, though. BTW, I personally use a Powerlogix Z-force carrier in my Powerbase (one of only ones, aside from first gen XLR8s that supported it). There isn't really much to the card.

    9600 604ev@500MHz

    Nah, you'd have to use something like Powerlogix's CPU-Director or XLR8's Mach Speed Tools to do so. Mind you, I'm not sure if they'll support a 604, though. I've never tried on anything below a G3.

    9600 604ev@500MHz

    Interesting find. It's always nice to open a computer and find something aside from pure stock components. I'm surprised the Macbench scores are so low (aside from the FPU though). I wonder if setting the cache to write-back and enabling speculative access would help. I remember reading that reaching 450MHz was usually pretty solid but I don't remember 500MHz being reliable.

    Powerbases, L2 caches, and some chips.

    Oh, its been done in a Beige G3 by a braver soul many moons ago. It performed poorly due to the fact that there isn't a way to add the L2 cache it needs on a beige's motherboard, I believe. I don't believe he took it any further. Its an interesting project but doesn't really have any actual benefits.
  11. I finally managed to snag a 604e zif from one of those IBM servers. The chips were usually just included with their motherboards (which I didn't need or want), but one finally came out as a lone chip. It fits in well, dropped straight it. Although, as the picture shows one corned is slightly raised, not by much and I'm sure the pins are still making contact. I haven't actually ran the Powerbase with it yet as I'm having trouble finding a heatsink/clip to fit. I might end up fabricating up something crude but functional. What I'm wanting to know is how interchangeable are the L2-cache DIMMs between the Powermacs. I can grab the 256K one out of my 8500 or the 256K one I believe came out of my nonfunctional 6500 (caps gone). Does anyone know of somewhere to get a 1MB cache that might work in this Powerbase. Its going to need a cache on this motherboard with slow ram and a slow bus. Mind you, that's if it works.
  12. Most likely they simply never flashed it or flashed it incorrectly. In either case they didn't seem to have tested it before sending it out the door.
  13. They could go to 128GB or 127 point something. I think the 8GB "limit" technically could affect OS 9 too when a system file fell out of the first 8GB.

    Powermac 6220CD

    Interestingly enough, I'd been interested in them forever floating around on ebay. I bought one some time back and actuallly used it in my G3-upgraded PCC Powerbase. It was... interesting. This was the "faster" ThunderPower one meant for higher end 604s (no DSP board connections; still there but the pins aren't). It had some interesting (standard on 2D cards at the time) features: pan-n-zoom and setting a virtual resolution higher than the resolution on the display. Performance against my Radeon wasn't impressive for a multi-grand card (I thought it would compete 2D-wise). I honestly think they just plunked their nubus architecture on a pci card. It did have 30-bit DACs, for what's it worth. Being as Radius always gave the card a name (1600 etc) based on the highest resolution offered in 24-bit, I don't know why they called it the Thunderpower 30/1920 since it only had 6MB VRAM and simply couldn't pull it off.

    Power Macintosh G3 Minitower Upgrades

    Late to the party. Anyhoo, if you can snag an original Radeon Mac Edition that would be closer to the 9200's performance than a Rage 128.
