    Let's talk Nubus DOS cards...

    Per the article posted on jagshouse.com (http://www.jagshouse.com/DOScard.html) it seems that the PM 6100 Dos Card will work more or less - under some configs perhaps with caveats - in the following machines: Centris 650 Quadra 650 Quadra 700 Quadra 900/950 Quadra 800 Powermac 6100/66
  2. I wonder, when you "pledged" your hardware, did you apply it directly to the circuit board, or did you apply it onto a cloth and wiped carefully? How exactly did you do it?
  3. Hi Guys, Yeah, I was pretty weary at first taking off the stock cooler since I've read the article about cracking/breaking 601's. I removed the board from the case and made sure to be extra careful when unclipping and replacing the heatsink. So far so good and no damage done *phew* Trag, after taking off the stock heatsink it was pretty obvious that new thermal compound was needed. The stuff was so dried up it wasn't even funny - almost like plaster you use for spackling drywall ... yeah ... I ended up using the heatsink that came with the 486 DX/2 that I pulled off the DOS Card since it offers quite a bit more surface area in comparison to e.g. the heatsink from a 6500 (see the "potential replacement" screenshot, it's tiny and seems to me that it might not be large enough). With the Cyrix 5x86 and it's attached heatsink, interposer and all, and the 601 with the 486's old heatsink, I have about 12-13mm clearance left between both CPUs. I wasn't able to use the stock heatsink since it's just too tall (I have considered just dropping in a fan but the height of the fins won't allow installation of the card). I haven't been able to get too much testing done since I had to get some sleep before work, but I ran the setup without fan for a little while (half an hour or so), using both the Mac and PC side of things to see how hot it actually gets (with case closed and machine slightly raised to allow proper circulation). The Cyrix seems to be just fine, the 601 does get quite warm even with the heatsink. Since there really isn't that much clearance between the CPUs I've tried to figure out a way to see if I could possibly add a fan sideways rather than on the heatsink in order to force airflow over the fins (like some of e.g. the Sonnet G3/G4 accelerators do). Doesn't seem to be an easy way to accomplish this. I was able to mount a 40 x 40 x 10 fan on top of the 601 which *barely* fits. Since the CPUs are not directly stacked on top of each other, but rather slightly offset, there is some room for the fan to draw in air and to force air over the heatsink, but I have not been able to test how *hot* it actually gets yet with that setup. I ran it briefly without the DOS card and it indeed only got lukewarm (which is good) but it remains to be seen how it will perform "in the field", with DOS Card installed and case closed. I've seen some of these heatsinks which came with e.g. the 601 addon cards, they seem to be not quite as tall as the 6100 contraption, but seem to offer quite a bit more surface space. Not sure if this will work in a 6100 considering e.g. capacitors, chips, etc which might obstruct the heatsink, but I might look into that. It would definitely not use nearly as much vertical space as the other sinks I've tried so far... In the end, you may ask why bother with all this if there are different machines which can do exactly the same, if not faster and better? Well... 1.) The 6100 was the first PowerPC machine (sentimental value) 2.) I like the pizza-box form-factor 3.) A "VM" implemented in hardware (an x86 compatible CPU grafted to PPC architecture) is total geekery which I like 4.) I have both old Mac and DOS/Win3x titles which I can bring "under one roof" with this setup 5.) Regarding the Cyrix 5x86, it "smokes" the Intel 486 DX2/66 - when comparing 486s that is Getting off the soap box now, so If you've made it this far, thank you for listening to my ramblings (3:20am and my brain's not working)! ~BeniD82
  4. Hi Guys, I have been contemplating on moving the Cyrix 5x86 CPU which I am currently using in my 640 DOS Compatible onto the 6100/66's DOS Card. Since the Cyrix CPU requires an interposer which converts the 5V provided by the card's socket to 3.45V which the CPU requires, there would very little clearance left between the two CPUs (they are just about on top of each other). It seems that the 601's passive heat sink uses a significant amount of space, so I was wondering if you guys think using e.g. the heatsink from a 6500 in combination with a fan would suffice to cool the PPC 601? The 601's can get pretty toasty, at least when passively cooled, so my presumption is that with active cooling I might be able to pull it off. What do you guys think? Since I am at work I can't provide actual screenshots so I shamelessly ninja'd two from Zone6400 and the Internet respectively Current Heatsink: Potential Replacement: Other considerations are that the Cyrix does not require active cooling and has a "built-in" heatsink on the ceramic itself so it would use less space than the current DX2/66 and its taller passive heatsink. Anyway ... ~BeniD82

    Where should I put her?

    All my machines except for the Cube and the CC are stored in my TV cabinet. Since I don't have a decent CRT for my machines I have repurposed my 40" LCD TV as monitor since it offers VGA connectivity. Kind of overkill for machines which usually just display 640x480 (the 6100/66 DOS Compatible and the Performa 640 DOS Compatible), except for the 7500 which runs at 1024x768. The cube sits permanently on my desk near my PC beast, and the CC is floating around depending on my mood - it doesn't have a permanent home yet. I guess in the end storing/placing your machines will depend on how frequently you plan on using them (if frequent then they should be somewhat accessible). Ideally they should be kept out of direct sunlight and away from artificial lighting in order to prevent any potential yellowing. Also, a less dusty environment can be rather helpful... ~BeniD82
  6. I have to admit that the description for this one isn't very specific. One can only assume at this point, but according to VRAM Chart (http://support.apple.com/kb/TA29136?viewlocale=en_US), if it's 68pin VRAM then just about all of the LC/Performa/Quadra/Centris could use it. Guess it's time to call/email in order to find out more details (speed, etc.) ~BeniD82
  7. Hi Guys, Not sure if you guys have any use for this but I figure it can't hurt to share the information. While most Power Macs these days can or have been upgraded with either a G3 or G4 accelerator containing an exuberant amount of L2 (or even L3) cache on-board generally, in some cases, machines such as the Performa 6100/66 can't really utilize an accelerator if using either a Nubus or DOS Compatibility Card. Since I still wanted to be able to have a somewhat responsive system but without sacrificing my DOS Card, I had been looking for ways to somewhat improve the overall performance. I had been using 256KB of L2 cache so far but I had heard of the existence of a 1024KB (1MB) L2 cache module. Let me tell you, I've had a hell of a time finding one (these buggers seem to be rather elusive!) - until now! Searching the almighty interweb I stumbled upon the site of a company named "Data Memory Systems" which still seems to have some on-hand stock of L2 cache modules. I figured I'd give ordering one a try so I ended up ordering the 1MB L2 Cache Module for the 6100/7100/8100 series of Power Macs, and at $2,-- per module - which included shipping nonetheless - I figured heck why not. I am happy to report that I did indeed receive a L2 cache module rather than an email stating that they're out of stock but haven't had a chance to update their site yet! It's pretty big and heavy in comparison to the 256KB module (I'm scared of it somehow ... in a really strange way) but it certainly works like a charm! The performance increase is quite noticeable, even in comparison to the 256KB module. Anyway, if there are more oddballs like myself who either can't or won't upgrade to a G3 accelerator, here's the link to the site (also, if accessing from the main page, scroll to the "Clearance Items" and then to "Apple VRAM & L2 Cache Cards"): Link: http://www.datamemorysystems.com/Apple-VRAM-&-L2-Cache-Cards/C_1143 Regards, ~BeniD82
  8. To me personally the Radeon 7500 AGP Mac Edition is the best choice when considering the relationship between cost and performance. It fits into the cube just fine and you won't have to do any modifications to either the cube or the card other than removing the slot cover since it won't align with the Rage 128's fencing. I got mine off eBay for 20,-- so that's still feasible (unlike e.g. the Geforce MX/4 or whatever that thing is called exactly). Runs beautifully with full driver support under both OS 9.2.2 and OS X 10.5.8 at 1080p (granted I am at max RAM and using a Sonnet 1.8 GHz CPU). -- BeniD82

    Fully boxed G4 Cube and Monitor

    ... Woah! I would say you got a great deal on your cube, considering I paid about $450,-- for mine, which isn't nearly in as good of condition as yours. From what I can see by your screenshots your Cube is in nearly pristine condition, which is AWESOME! Mine may not be in top physical condition (few nicks and scratches here and there) but I don't like it any less. Makes a great *compact* machine for botch Classic and older versions of OS X, especially if you can source some extra RAM and a Radeon 7500 Macintosh Edition (both should still be readily available on eBay). The Radeon definitively made a BIG difference performance wise in OS X. Again, congratulations, definitively a great conquest! ~BeniD82

    Confusing Cube

    Hey There! My Cube has the tendency to shut off if I move it around. I found out that in my case this is caused by USB connectors on the bottom of the cube. The connectors are in terrible shape (they look VERY ABUSED, bent/broken pins, warped houing - yeah, it's ugly) so when you move the cube, anything plugged into the connectors (especially the Cube-specific Harman Kardon speakers) will cause a short which will shutdown the cube if it's running, and also won't allow me to start it back up. Wiggling on the connector will usually fix it (may take a a few nudges but it will boot up again). Like I said, as long as I won't touch/move/pull/tug on the plugged in USB devices she's purring like a kitten, but boy if you move her ... she definitively doesn't like to be moved I'll have the conectors replaced by a professional sooner or later (my soldering skills aren't *that* great) because it's definitively a pain dealing with faulty USB connectors on the Cube, especially when considering that USB really is the *only* way of adding additional functionality to the system (other than FireWire, but honestly other than hard disks or camcorders/webcams I haven't seen FireWire being used for anything else). If I were you I'd turn the Cube upside-down and inspect the USB connectors to see if there are any broken or bent pins. Specifically look for any pins touching the metal housing because like I said this will cause a short which will not allow the Cube to boot; it will appear as if your Cube had a bad PSU or bad logic board, no startup bong, video, etc. In my case, once I get my connectors fixed I'll just plug in a self-powered hub into the connectors so I won't have to worry about any more wear and tear on the box because USB is so heavily used on this machine. Hope this helps! ~~ BeniD82

    Reply LC PDS Dos Card

    Oh yeah, not to forget, I actually upgraded the original Intel 486/66MHz with a 100MHz Cyrix 5x86 ... had to add a socket/power converter to get it working, but the difference in speed on the DOS side is VERY noticable!

    Reply LC PDS Dos Card

    Sorry for "raising the dead" so to say, but I just wanted to add my two cents... I own a Takky Colour Classic which is now actually fully loaded, containing the guts of a Performa 6500 with a Sonnet L2 G3/500, CS II ethernet, A/V card, and some no-name USB 1.1 board in the PCI slot. Before going for the full-fledged PPC mod, I actually tried the Mystic mod first (LC 575 boad), in combination with the VGA mod, which was shortly after followed by my Takky 68k mod. After making the necessary modifications to the harness, I dropped in the logic board of a LC 630 DOS Compatible (or was it a 640, can't remember, but it has two memory slots) into the CC and I can say it worked like a charm. General video tasks on the Mac side were ever-so-slighly slower than on the LC 575 due to the 580+ models using regular RAM rather than dedicated VRAM and getting ATA/IDE to work properly was ... uhmm yeah ... fun ... but other than that it actually performed really well! Being able to switch between Mac and PC environment on a fly, all self-contained within this little beige box with that tiny 9" Trinitron color tube, I have to admit that this definitively bought my inner geek out of me. Too cool. I've used this setup for quite a while but due to my insatiable hunger for more Power(PC) I ended up replacing this board with the Performa 6500 logic board and couldn't be happier. About a year ago I acquired a Performa 6200 Road Apple for very cheap, tossed the board since I really just needed the case (I played around with it for a bit, and yes, they definitively deserve that title) and dropped in the LC 630 DOS Compatible. This has become my main 68k machine which I hope I'll be able to keep running for as long as I can. It may not be a top performer or the most visually appealing machine when comparing it to the other 68k models, but to me this setup is a prime example of "ingenous professional hardware hackery" which makes it quite unique to me, especially when considering that what we now can do at ease and on the fly in software, e.g. through emulation, actually had been implemented in hardware a mere decade or so ago ... again, this is just my inner geek speaking again. -- BeniD82

    DVD on a pre G3 Mac

    I ran into issues on my cube (stock Rage 128 and Radeon 7500) when trying to play DVDs after having installed OS 9 using the OS 9.1 disk (kept telling me that the hardware could not be found, which is weird knowing that it is an Apple-branded super drive and that it's working great in OS X 10.4). After reinstalling the OS using my OS 9.2.1 disk, the Apple DVD player software apparenly "registered the hardware" and DVDs play just fine. I'm not sure if it's related to the version of the Apple DVD software, DVD/video driver but using the 9.2.1 install did the trick for me. Not sure if it helps but I figured I'd at least throw my two cents out there -- BeniD82

    Apple Pro Keyboard (Black) Sticking Keys?

    So.... I had an epiphany a few minutes ago. Since searching for a replacement "rubber plunger" or "rubber dome" has been pretty much an exercise in futility and I really do not wish to gut a working keyboard just for a few parts, I tried to think of an alternative. I considered some type of coil or spring (such as in a ball point pen) but since I didn't have anything workable available, that idea had to be canned. I ended up cutting a few pieces of foam into the correct shape, placed these under the space bar, popped the bar back in, and voila, it is working! This may not be an elegant solution but it seems to work just fine I'll probably see if I can find one or two springs to try replacing the foam with, but like I said, the foam is doing the trick for now, yay!
