  1. Yeah, a straight through serial cable will work. Note you'll get ghosting without a shielded cable though. I picked up a 9 pin straight through cable meant for video on a KVM of sorts I've been meaning to try but haven't got around to it yet.

    E-Machines Big Picture Card w/Mac SE Interconnect

    Hey, I'll take that Big Picture card. It'd be fun to try and make work on the GCC Hypercharger passthrough. Not a lot of information on the card so I bet it won't work on LCDs ,a good multisync CRT maybe.

    Starting on the SE

    No, that'll just gunk up everything in short order. You'll want to clean it up and use something like white lithium grease that doesn't dry out rapidly and won't attract dust.

    SE/30 logic board foreign object?

    That's a small surface mount capacitor shoved in. For what? I don't know, but if it works, I'd leave it.

    Board repair recommendations

    Did you lift a pad or lift a trace? Lifting a pad is generally pretty easy to get around. You can scrape a little of the solder mask off the trace (carefully) and bend the lead over to solder onto that, run a small piece of wire from trace to component lead (if it can't bend) or just run a wire to bypass the trace\pad entirely. If you lifted an entire trace, that's a little more difficult and kind of an achievement on its own. In either case, try adding some liquid flux to the joints, adding new solder, adding a little more flux then using a vacuum desoldering gun to clean everything up. Once I got that done, I lift a lot less pads. There're plenty of people in they bay area give or take (myself included) but man, I only trust myself to repair my own stuff, don't think my skills are up for other people's stuff. [

    Marathon Computer iRack DV

    That's an RS/6000 40p. 66 MHz 601, some amount of ram, 350 meg hard drive, Diamond S3 based video card. Running AIX 4 now, although if I can dig up the PReP floppy for it, NT4 would be fun to try out. It's not particularly fast, but the NT4 support is the only reason I really got it. I've got two other 80 MHz boxes (MCA based), a 375 MHz 604e and a Dual Dual-Core 4.2 GHz Power 6 box sitting here if I want to play with AIX.

    Marathon Computer iRack DV

    Right about a year later, luck strikes again. I'll do some testing and pics later, but I've gotten three more iRacks. Now I have three iRack DVs and two original iRacks. I'm going to have a whole datacenter of these things in a few years at this rate.

    IIsi works, then doesn't

    Power supply caps in these systems (both 475 and IIsi) are known to fail. Sometimes they work after sitting, sometimes they work after a few times, sometimes they work with some heatgun action on the caps, sometimes they don't work at all. In some like the 475 (and LCs) you can often hear the power supply ticking as the thing tries to start and fails over and over again.

    Macintosh LC Takes Forever to Boot

    Does it chime then take 10-20 minutes or does it make no sound and just take that long to get going? If you haven't already, you're going to need to recap as a first step, both logic board and power supply. With these particular systems, the caps aren't a "which one" but "Which one hasn't" unfortunately, and the longer they sit the more board damage they can do. Here's a list of logic board caps you'll need: 5x https://www.arrow.com/en/products/tajc476k016snj/avx 4x https://www.arrow.com/en/products/tajc106m016snj/avx 1x https://www.arrow.com/en/products/tajc107k006snj/avx Total cost (including shipping) is $2.82.

    Apple PHX 100

    But isn't the 603 more akin to a Celeron than a Pentium II/Pentium III? The higher end x86 boxes were the Pentium II and Pentium III, while your home consumer model was typically a Celeron or K6. The higher end Macs used a 604/604e while there lower end were a 603/603e. You could get something more consumer like a 7300 with a 604e just like you could get higher end consumer boxes with a Pentium II/III. Both cheaper than the full blown HP Kayak or Powermac 9500.

    Yellowed(brown?) Performa 550

    I'm all for woodgrain chassis and gold buttons. It'd certainly be unique .

    Tantalum recap success

    I’ve found flush cutters to cut the cap off then flux + desoldering gun to work really well for removing caps and not damage pads. Makes for nice shiny clean pads as well. https://i.imgur.com/QpQEJ5C.jpg[/img]
  13. It’ll work fine without the L2, it’ll just be quite sluggish. Think like a PowerBook 1400/117 if you’ve ever used one of those. No idea on the ram.

    Se/30 have to bang the box to get a screen

    Check the solder joints. I bet there's at least one cracked joint.
  15. I'm not terribly surprised. I have a PowerComputing something or another 200e here that also had bad L2 when I got it. In my case, I wouldn't even get a bong though, just turn it on and nothing. Ultimately ended up just throwing a spare G3 upgrade I had in it and it's been going ever since. Wonder if it's just coincidence or if maybe there's a defective thing with some of the L2s PowerComputing used.
