    SE/30 can’t find HD

    Well, the fuses are fine, I plugged in a Zip drive with active termination into the rear scsi port with no luck, then I got out a magnifying glass and took a look at the scsi controller. Looks like when the previous owner recapped the logic board they didn’t deal with the corrosion damage from cap goo under the scsi controller.

    Yeah, you can see the SCSI controller in this pic of my board (back from the happier days when it was running)

    SE/30 can’t find HD

    Replacing a 44 pin SMD chip like NCR53C80 is definitely well beyond my comfort level, soldering equipment, and skills. Replacing the fuses I could do. There are 2 there .. F2 and F3. One or both? What are the specs of the fuse? They look fine to me, I don’t know how fuses like that look when they blow.

    SE/30 can’t find HD

    I can’t figure this one out. I have a socketed SE/30 with a daystar powercache 40mhz accelerator in it that suddenly stopped finding the hard drive. There is nothing wrong with the drive as it works fine in my other (unsocketed) SE/30, and it won’t find my scsi2sd when I tried that. It boots fine off a floppy or a floppyemu. The motherboard was recapped a couple years age, and it has run fine until now. I tried tattletech, and that said no scsi devices are connected. Lido comes up with an error “Arbitration failed! Check connections and terminators on all SCSI devices.” I tried re-seating all the ram etc. No luck! Any idea what might be wrong? Thanks!
  5. When the PRAM battery is dead, Wallstreets can take a long time to boot unless it has been left plugged in -- mine certainly does. Try letting it sit for a while and see if it works.
  6. Where did you order the PRAM cells from? I've been trying to find a place that will ship to Canada that has batteries for less than US$14 a cell. I will just have to put up with resetting the clock and a slow start if it is going to cost US$84 plus shipping to rebuild the thing...

    Daystar SE/30 Powercache help

    It is the 40MHz . . . the label was worn off the crystal and I originally thought it was a 50, but testing proved otherwise. Yeah, 32-bit clean will be nice. I have 20mb in there now with mode32. I tried to swap the 32mb out of my other SE/30 but those simms did not work in the socked board for whatever reason.

    Daystar SE/30 Powercache help

    I have been playing around with my new SE/30 with a Daystar SE/30 Powercache for the socketed motherboard, and I have a few questions about what is needed to run it. I have OS 7.5.5 on my computer, and I installed the Daystar Power Central v1.3 control panel, which is the only one I could find. I should be using v2.2 with OS 7.7 according to this: http://lowendmac.com/daystar/pages/dsd_products/support/upgrades/faq_03040.html Does it matter that I am using v1.3 and not v2.2? I am considering installing OS 7.1 instead, as I prefer it. Plus I managed to snag a IIsi rom on ebay for $12 and I am a bit intimidated by the number of steps in getting it to work properly under OS 7.5. On the other hand, this computer also has an Asante ethernet card, and from what I gather there is a bit of futzing to get that fully functional under OS 7.1.

    SE/30 Missing HD, Bracket, and LED. What are my options

    I used zip ties to hold the hard drive to the floppy bracket on mine that was missing the HD sled. Just slid them through the top of the FD bracket. The HD shifts a little bit, a couple mm at most, but it seems to hold it pretty well.

    Yeah, I'm going to have to find a long term solution to that broken clip someday. I'm not afraid of soldering, but my equipment and skills are probably not up to replacing it.

    Phew. Just badly seated ram. One clip is broken on one ram stick.

    Oh, for crying out loud. It was working fine, but now that I've put it back together I am getting chimes of death and horizontal stripes.

    It's missing the top sled for the HD though... the HD was just sitting there loose, on top of a piece of plastic. Good thing it never got bumped over as it probably would have taken out the tube...

    Fimbulvetr's finds

    I picked up an SE/30 with keyboard and mouse off kijiji today. The seller was a young guy, and wanted CAN$140 for the thing. The ad said it was upgraded with a 2GB and worked great. I noticed it had an Ethernet card and looked clean and in nice shape, so I decided to check it out. The guy said it was a gift and he had no use for it. After giving it a test run I bought it, and of course the first thing I did when I got home was open it up to check the condition and look for a maxwell bomb that might need diffusing. Not only did I find that it was beautiful and clean inside, it had been recapped (with original style SMD electrolytics), had a new battery, an Asante MacCon Ethernet card, 2TB 50-pin HD, and ... a Daystar Digital 50 MHz 68030 powercache! Somebody must have really liked that guy to give him such a nice SE/30 as a gift.
