    8 Pin MiniDIN to USB?

    I just want to add that Amazon sells things that will never work, and possibly cause damage. Like this serial to FireWire adapter https://www.amazon.com/EarlyBirdSavings-Firewire-Adaptor-Converter-Connector/dp/B008XYG4KA/ref=sr_1_7?crid=1OP1LNWV4C2LS&keywords=usb+firewire+adapter&qid=1585281488&sprefix=USB+fire%2Caps%2C160&sr=8-7

    SE/30 does not boot

    I don’t understand why there’s no flashing question mark.

    Discharging a CRT - video

    It might give you a bad shock & burn, but there are no examples of death (until now). Refer to authorized technician only.

    Macintosh SE Clock Battery Mod

    Yeah... NO! When the battery runs down, the clock won’t slow down. It won’t have enough voltage to run the oscillator, and the clock will act erratically, or just not work. The oscillator can only run at its fixed frequency.

    Macintosh SE Clock Battery Mod

    There’s a chance that a alkaline battery will leak.

    Macintosh SE Clock Battery Mod

    I think this is too much “hackery” for a $8 battery that lasts 10 years. I always use the correct 1/2 AA battery. There are too many people out there saying they explode, but that doesn’t happen until the battery is completely dead, and the chemistry reverses polarity, creating a “takeoff” reaction.

    Hate to do this but... SE/30 Help needed

    60/40 solder will do just fine, and doesn’t have a high melting point, which can cause more problems to the traces & vias.

    New member buys a macintosh se/30

    Welcome! From the Classic Mac Repair Notes (http://www.ccadams.org/se/classicmac2.pdf) “The reason for the nonconductivity requirement is that the control is actually a ferrite core inside an inductor carrying large alternating currents. The AC field would induce large currents in a conductive tool, and make it get incredibly hot very quickly, to say nothing of invalidating the adjustment. At the same time, the increased strain that this places on the circuits could cause damage. So, wood or plastic it should be. “ So, by using a metal screwdriver, you’d be changing the inductance just by putting it in there, without even turning it. ...And, the Classic Mac Notes is a good reference that I think everyone here has read or referenced, along with Larry Pina’s books, and others.

    IIci PSU shrink-tube optional?

    The top of the capacitor in the first picture looks popped to me.
  10. I always hated that the Beatles sued Apple, and thought it was stupid. Nobody went to the store and said “I want to buy one of those Beatles computers. It must be a Beatles computer because there’s an Apple on it”.

    IIci PSU shrink-tube optional?

    Do you mean the Standard wrap with the markings / rating / branding on them, or is there an overwrap? The standard wrap is also there because the can is often connected to the negative pin I once saw a video where someone said (while pointing to a bank of caps with overwrap & glued to each other) that its done to reduce vibration while isolating vibration, because caps vibrate (oscillate) when they are working, which I already knew. I think it was Ave, or Mr. Carlson, or Big Clive.... Idunno, It's a big tube out there. Where are the pics? Picture books are fun. Those word books are yucky.
  12. @Knuckx NO! The card is not SCSI. It cannot be used for SCSI. It WILL NEVER BE SCSI!!!! You will have to use the onboard SCSI, or a separate SCSI card. ...And a FAST hard drive, or SCSI2SD. You will get "Disk To Slow" errors if the disk isn't fast enough. You pretty much have a project / learning experience on your hands. But, depending on your patience, it could be fun. (Oh! The drivers & Digi Engine Errors.. UUuuugggg) After all, An iPhone has more power than ALL those cards & computer combined. You can get a 882 for $30 + $10 S&H here: https://www.ebay.com/itm/Digidesign-882-I-O-Audio-Interface-Black-No-Power-Cord-Untested/183991741907?hash=item2ad6c32dd3:g:Hs0AAOSwKVVbOUlz:sc:USPSPriority!60615!US!-1 And you'll need a HD50 cable to link them.... Yes. The same as a Sun Micro HD50 https://www.ebay.com/itm/SCSI-Cable-HPDB50-to-HPDB50-6-ft-HD-50-to-HD-50-SCSI-2-to-SCSI-2-NEW/113164971341?hash=item1a59286d4d:g:ahEAAOSwux5YMxfJ THE CARD WILL NEVER DO SCSI !!!!
  13. I saw someone in Michigan had one of these, and it looked pretty cool and interesting, but I couldn’t find a useful reason to buy it, other than “just to play with”.

    SE FDHD Restoration

    I believe we found it to be this one: https://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/640456-2/A1921-ND/109003 Check end of first page, and beginning of 2nd page of this post for other info.
  15. Geez... another reply from me! I was wrong, and that card can be used with the 882 or Session 8. And you can get protools “3.4 free” here: http://www.oakbog.com/PT3NuBus.html
