  1. I used a super cheap micro SD extension for years in my SE/30 from China I got off of ebay, no problems. I only took it out recently after I moved the computer and snapped the end off of the micro SD card.

    Shoulda backed that card up. 

  2. Completely recapped, and I have a scsi2sd in it. This has been a reliable workhorse until now. There was a video card in the slot that came with the computer when I got it years ago. I never used it, just left it in because it was there. So I replaced that with the network card. The chimes now happen whether or not the network card is in, only at a cold boot with 32-bit on. I tried se-seating the RAM and ROM. 

  3. I am having a weird problem with my SE/30 and an Asante ethernet card... I know the ethernet card works, as I it was working in the SE/30 I pulled it from (the SCSI chip failed on that one, and I don't have the skills to replace it). When I put it in my other SE/30, I the normal chord and a happy mac at startup, then it hangs at the happy mac and I get a two-tone "ta-da" chord, followed by the four-tone low-to-high test chord. Then the computer hangs indefinitely, but when I reboot with the programmer's key it it starts fine, no hangs, no weird tones. The Asante card test from the installation disk runs fine, so the network card is working. The computer restarts fine on any subsequent soft reboots, but if I shut down and restart I have to go through the whole two-step reboot process again. I am running system 7.1, Asante driver is 5.1.2, and I have 32 Mb ram installed on the machine. 

     

    Any ideas what might be going on? Thanks!

  4. Yeah, there is something off with the power supply. From a cold start is just sort of pulses -- fan, light, everything, until it warms up or something, then it runs.  I could re-cap it and see if that fixes it, or I could just pull it out and replace it with a new 12v Molex power supply from China for $7 like this one:  https://www.ebay.ca/itm/External-12V-5V-2A-USB-to-IDE-SATA-Power-Supply-Adapter-Hard-Drive-HDD-CD-ROM/173586174276?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Dd0dd25a599dd4d0b958c5219869fde68%26pid%3D100675%26rk%3D4%26rkt%3D15%26sd%3D264215500913%26itm%3D173586174276&_trksid=p2481888.c100675.m4236&_trkparms=pageci%3Ac5e738c8-39fb-11e9-ba0f-74dbd1809b23|parentrq%3A2b4198ca1690a9cb6e08ffc2ffea363b|iid%3A1

     

    The $7 Chinese power supply is gotta be cheaper than caps.

     

     

  5. Screen seems to be working better now that I’ve fiddled with it. It is still always blank on first start, but one push of the reset button fixes that. The button pusher I whittled out of a bit of dowel ended up working much better than the original plastic one. I may end up whittling replacement pusher for all of them...

  6. Well, I tried swapping out the original Seagate ST-1096N HD with a Seagate ST32151N that I know works, and it didn’t work. The new HD wouldn’t spin up, even the fan on the Ultradrive would just pulse and the power light flickered. I put the old drive back in and it spun up and powered up with no problem. It looks like the old drive will actually mount if the Ultradrive is on its side, but I’m sure it will permanently crap out at any moment.   The new drive shouldn’t need more power than the old one, should it? Why won’t it power up with the much newer drive?

  7. Huh. I bent those metal clip things (which helped, but was how I lost that stupid @#$%&# button pusher ... guess I'm whittling one out of wood now), but I've never had it apart to see the gold finger thingies. I'll have to check that out. 

     

    I wonder if soldering it together instead of relying on pressure contact would help, and if that is even possible.

  8. I have the previous model of the floppyemu. I absolutely love that thing except for the damn screen. It has given me trouble since day one where it goes blank after it has been running for a while or it is blank when it starts up . I have to fiddle with how the screen is seated or reset it a bunch of times before I get anything on the screen. I mentioned the screen problem to BMOW and that was Steve's suggestion for the problem.  The screen is a known weakness with these things, and Steve has mentioned on the BMOW website that he is looking into a new screen. This problem has been getting worse as time goes on, and lately it has taken many tries to get the screen to work and now it sometimes just shows gibberish before I get it to display correctly. Last night was really bad and then I lost one of the stupid fiddly little button pushers for the case, which did not help my mood at all. Does anyone here have any solutions for getting the screen to work more reliably? It is an indispensable tool for keeping my old macs going, but the frustration with using it is starting to drive me crazy.

  9. I recently picked up a GSS Technologies Ultradrive 80 external SCSI hard drive to use with my compact Macs. I've never used an external SCSI HD before. The HD in the enclosure made horrible noises the first couple times I powered it up, then it finally spun up. After a bunch of tries I got it to mount once -- it was still full of some families files from the early 90's -- and then, not surprisingly, it never mounted again. I was expecting this, and had only bought the thing for the enclosure with plans on replacing the drive. I have a good 2 good 50 pin SCSI HDs (a 40 Mb and a 2 GB) and a SCSI2SD that I could put into it. My question is, can I just swap the drive out? Or is there something I need to do to get the thing working properly... I think I would prefer using the SCSI2 SD in it.

  10. 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.

  11. 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.

  12. 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!

  13. 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.  

  14. 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:

    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.
