  1. So when I first acquired my PowerWave, it had some posting issues which were due to RAM, which were resolved quickly and the machine ran well. However, after decided to upgrade from the "fine" Mach64 with a Rage128 I had sitting around, things got weird: get a chime and then the screen gets a signal briefly, then nothing. not even a black screen, my monitor just says there's no signal. The machine wouldn't post at all, even after a board reset before powering back on. Tried pulling RAM, reseating the ROM, reseating and changing out CPU daughtercards. Nothing. I put the Mach64 and it immediately posts and boots right up. I upgrade/reinstall the ATi drivers, shutdown, replace with the Rage128, reset the board, power on, and after a few seconds it finally posts. Okay, fine, no harm done I guess. Time comes where I have to reset the PRAM. Upon doing so, I'm back to a black screen, no posting at all, nothing beyond the bong. Would the ROM on the PowerWave just see the Rage128 and not know what to make of it because it's too new? This all seems very odd. Just wondering if anyone has any advice or has had a similar experience. Edit: as an addendum, if it really is something about a contemporary (to a PowerMac 85/9500) that it needs as far as a graphics card, what would be a decent replacement for the Mach64? VRAM modules for them are nearly double what you can get a standalone card for.

    PowerWave weirdness | picky about video card

    Grrr. I keep on discovering new information with each post... Apparently the PowerTower (not pro) 180 (not 180e) runs at a 60 MHz bus speed? even though the Tsunami design spec didn't? The 85/9500 doesn't appear to run at 60. Ah, but the original PowerTower was Catalyst-based?? and only PCC made their Catalyst boards run at 60? My brain right now... I need some sleep. Well, then, I guess the 604/150 from another PowerWave is the non-604e ceiling, if MacInfo.de and Everymac are to be believed.

    PowerWave weirdness | picky about video card

    Interestingly enough, I started to catalog each of the CPU daughter cards in hopes of IDing ebay listings that dont show or are missing the speed sticker/decal, but they didn't seem to differentiate by clock speed. This was all done on a whim, so I haven't put my cards in this list yet—these were complied from ebay. Also on a whim, I bought a $7 card (the one at the bottom), and it was missing its stickers, so once I get it I'll put it in. If everymac is correct, then the PCC 604/180 is the fastest non-e 604. I don't have any other pci, pre-G3 power Macs but I'm sure you're correct in that the PCC cards could NOT be used in genuine Apple motherboards. Eventually I want to add the Apple cards to this list as well.

    Sadly, no Just the PowerWave at present. I would buy this if they shipped… https://minneapolis.craigslist.org/dak/sys/d/south-saint-paul-apple-mac/7026386503.html

    PowerWave weirdness | picky about video card

    Because the PowerWave was based on the original Tsunami design? So the 604e 85/9500 used a revised design then? Hooked it up and tried last night—it could reset the PRAM like nothing was wrong to begin with… PCC used to brag that you didn't "have to pay extra for the keyboard" and I guess there's a reason for that! I was talking it up in my head, with it's wired connection plus TWO ADB ports for peripherals, and the echoes of the EKII on the sides, full extended layout with F-keys and 10-key. But yeah, I can't even move, run, and strafe at the same time in DOOM with the PCC keyboard I need an Apple Design Keyboard to test against, as it was more of the contemporary around PCC's rise to prominence, right? I wonder, since I'm not really going to be using the Mach64 elsewhere, if I should just plop both cards in there for the unlikely event that something goes awry… I still want to track down anything documented about the more modern PCI cards jacking up these 1st gen PCI designs.

    That would make me feel less inane That only happened with the 225 MHz PCC daughtercard, actually. Not with the 132 or with the PoweForce G3 (currently installed), and hasn't repeated itself. It was incredibly weird though. As far as the other machines I've used it in, I have 0 issues with the card, pre-, post-, or with a PRAM reset. The only OWR machine that's given me issues is the PowerWave I did experience that sort of monitor wake thing, but I leave it for minutes on end (in the PowerWave) and I get nothing. Part of me wants to get another NWR graphics card and see if it's repeated.

    PowerWave weirdness | picky about video card

    Y'know, that's something that crossed my brain and immediately dismissed out of stubbornness/pride I had talked up the keyboard in my head... I have been using the PCC adb keyboard ever since I got it, and noticed some anomalies, mostly while playing DOOM— not being able to maneuver like I'm accustomed to. I'll test it out with my AEKII. Thanks for the thought.

    PowerWave weirdness | picky about video card

    Runs just dandy on my 4400 and my beige PMG3. It's a Mac-specific card as well—came from a B&W G3. And, I mean, up until there's a board reset or the PRAM battery is taken out, it runs just fine. I'm kind of tempted to try it again now that I have my PowerLogix G3 daughtercard working. Part of me thinks something funky was going on with the two 604 cards, as they were not the originals that came with the machine (when I got it). It came with the G3, but was running OS 8.6. Right now it's running very stably, and with 0 issues. When I was doing the diagnoses with the other two cards I would get random freezes every now and again. I think I'll try that next just for kicks. Edit; nope. same story... this is almost to the comical stage for me.

    PowerWave weirdness | picky about video card

    I thought I was making progress with my other CPU card (132), and I got the PRAM to zap just fine and booted up. Then I put the Rage128 in and it won't post again. Square one...

    PowerWave weirdness | picky about video card

    Edit: this first test was with the 225/45 PowerComputing CPU card well, I ran TechTool 3 and got some interesting results... it failed on some aspects of the disc, but I can't get the TT CD to boot, so I can't do full repairs on the HDD. No surprises that there would be some after all these years. What was strange was it failed the CPU math test. Don't know what to make of that, to be honest. The repair advice mentioned a few things, but basically said a qualified technician would be able to give a proper diagnosis. One thing that was mentioned was bad solder joints... on the CPU daughtercard connector?

    I should add, the PRAM battery is new and registering 3.666 V on my multimeter.

    PowerWave weirdness | picky about video card

    I did try that, and thank you for your thoughts. Turns out now that I can't zap the PRAM with alt+cmd+p+r ...that is very odd. When I try it just makes the machine hang on a black screen, no chime, nothing. Maybe that's a bigger issue here So so far the only method that works is pull the PRAM battery, put the Mach64 in, boot it, get everything set up, shut down, replace the Mach64 with the Rage128 (no board reset, no PRAM reset). Then it works. But there's something fishy going on here... I'm really starting to wonder if there's something wrong with the foundational aspects, maybe the ROM? Something else?

    PowerWave weirdness | picky about video card

    Now that I'm thinking more about it, again, not familiar with the particulars of the classic OS loading order, I wonder if the OS would really have much bearing on the card's compatibility. I'm thinking no, but someone correct me. So when I boot I get: 1) chime, 2) the monitor going from standby to actual black (getting signal?), 3) then head seek on the HDD, 4) then back to standby, and it hangs. Is it loading parts of the OS at that time, or is it just reading the ROM and prepping everything to load the OS? I'm loading my questions with a lot of supposition… barring any software snafus, I wonder what other hardware considerations there are to think about.

    Mighty Jabba's Conquests

    There's a recent post about it—Dont have the link handy (mobile), but I believe that the sawtooth, specifically, couldnt drive the higher power draw screens of the era, regardless of the graphics card. Edit:

    SE/30 rebooting problem with screenshot

    I just keep snagging the one on JDW's re-capping video https://docs.google.com/spreadsheets/d/18X-EN67lQdZ2crCBAlkHrtqCCoJK6cLw_BkIYdlJvgs/edit#gid=0

    Fan replacement for a Mac SE/30

    Maybe I'm sleep-deprived, so check me if I'm off my nut. Since the intake on these is on the bottom, there's this up and back airflow (blue) which would create kind of a low pressure situation (yellow) right up at the top (where the flyback is). Since the SE there were no more vent louvers at the top of the case, so the air wouldn't flow that direction, right through the flyback cage as might be the best goal. So I'm curious if a cowling, albeit a bit choked, might serve the flyback more by forcing the air to flow through the cage itself? I mean, obviously, it seems like placing the fan higher up, directly in the path of the flyback could have served airflow better (red), but spilled milk and all that. It would be a wonky fit at best, having to make space for board connectors. Way out of the realm of feasibility would be a modified cage for the flyback. anyway enough rambling…

    Discharging a CRT - video

    related: I watched a video which implied the original 128k, 512k models' PSU-come-analog-board didn't have a bleed off for the CRT, which was introduced in the Plus model. Can someone confirm that?

    Sonnet Crescendo L2 500MHz 1M

    I tried to overclock it (the board itself, not the Sonnet!) and I think I need different resistor values for it to work, according to the guide anyway. It's a Starmax 5000 board that almost fit in my Power Macintosh 4400 case (the extra I/O made it impossible without modification). But in essence, I got my Sonnet 500 for the price of that board, which was pretty good—oddly, the board wasn't packed well and the sonnet chipped off several components, so after I got it working of course I was going to tinker with more surface components and muck it up :facepalm: . If I can't get the board working, I might put up a trading post ...post to part-trade+downgrade to a 400. 500 is kind of a waste in a system like the 4400 without the appropriate 50 MHz bus speed, and I doubt I'll be looking/find for a PM 6500 or 5500 locally or for a reasonable price. My previous 400 MHz sonnet card worked with the standard drivers, and I'm finding I need to use the PowerLogix control panel to disable speculative addressing in order for it to boot and run stably at 500.

    Sonnet Crescendo L2 500MHz 1M

    Very nice. I've got a 500 sitting around for me to fix the motherboard it goes to I'm also impressed you got that Sonnet Tempo card in there. Is that for your main booting drive then? Is the TAM's riser just a PCI bottom, COMMII top?

    Macintosh SE/30

    I know there are quite a few people on here who would gladly take an SE/30 off your hands! A good place to start might be to scroll through the Trading Post threads; there was one recently, but I can't recall off the top of my head. Personally, I'm good for the moment, but even in what's called simasimac state, that SE/30 would definitely find a good home with someone here. It will most definitely need the capacitors replaced on the logic board, and the analog board capacitors as well, while it's out, so that's something to figure into how much it's worth. Other things to consider might be how much potential board damage there is, given the corrosive nature of electrolytic fluid over time. Generally, I don't think there are any hard/fast rules for pricing. It's all up to you. They go for many greenbacks on ebay these days, but I can say that from what I've observed, folks on here generally are pretty good about not flipping when they've gotten a good deal. It's kind of a gentlemen's agreement, but again, nothing hard and fast. I'd look for a post, and maybe someone might find this one, and you can start a direct-message dialog with them on the value.

    Broken solder joints

    In JDW's video, he says 350 C / 662 F, but I typically start at around 500 F on my weller station and go up if need be for projects like guitar stompboxes, Though I just looked at mine from the last solder job I did (SE/30 analog board) and it's set at 550 F. If it's a component on a large ground pad, hotter might be better in this case.
  24. The poor man's way of writing Macintosh 800k floppies (if you lack OEM 800k disk blanks) is putting a piece of tape over the non-write-protect hole (one without the switch) of a 1.44 MB disk. Any Old World ROM Macintosh can write and read 800k floppies AFAIK. Everything from the SE Superdrive till the last beige Power Macintosh G3 (pre-blue-and-white G3 towers), i.e. any Macintosh with a native floppy disk drive. Really the exceptions are USB-based floppy drives, which can only read/write Macintosh 1.44 MB floppies (and DOS floppies w/ PC exchange)

    Broken solder joints

    Yes, a temp controlled soldering iron is the safest option for sure. I'm not a fan of fixed temp irons myself, and while you'll pay more, I think it's worth the investment. AIt would be best to remove all the old solder and redo the joint. Also, a container of liquid or gel flux will aid in the removal of the old solder, and as said, rosin core lead solder will make things a lot easier when repairing. I would also get some solder wick as well. I like it more than a solder sucker, and it's cheaper than a vacuum, but that's personal preference. I'm guessing this is all on the analog board? Some of the traces can be pretty fat, so don't worry if it takes a bit longer to melt or apply the solder to those joints. I am super paranoid while soldering, and knowing this takes a lot of the edge off the job.
