    Safest technique for removing SOIC chips on SE/30 like UD8, UE8, UF8, etc.

    Hot air... Single edge razor blades make quick/ great heat shields, btw. If I'm being super careful I'll use kapton tape, a sheet of copper, or aluminum tape (depending on what surrounds the part I'm trying to take off).

    Overclock LC475/P475/Q605 without soldering or spicy-o-clock

    It disables the driver with 24-bit addressing. You'll notice the extension will be (red if I remeber correctly) and show a 24-bit logo.

    My New Quadra 800

    Super good advice! Every caddy cdrom I've seen with the front panel has had bad cap leakage! If it has damage I would leave the ffc unplugged. At least until your sure you have the cdrom @ 100%

    30Video: New video board for SE/30 / IIsi / more?

    I second that! ZZJoe's upgrades are an awesome compliment to an already amazing machine. ZZJoe's (and Bolle's) upgrades make the SE/30 the 21'st century's must have Mac (personal opinion, but i believe many have the same opinion). I love tube monitors, but that LCD looks amazing. It has me on...

    Mac Plus that went on fine (only the analog board)

    Big Bang Theory... 😁

    Mac SE/30 Silent no start-up bong

    Lol. I'm sure if someone banged their head against a wall a number of times when trying to fix an se/30, and then found out about the built-in diagnostics... it would be an amazing discovery. Saying that... I'm pretty sure that is click bait. Gotta get them views. Adrian is fun to watch. He...

    More information on Pro Tools 2 and 3 Systems

    I have a number of cards and a dongle that plugs into the adb port i'd like to get running. It will pass autorization, but is looking fornsomething else to boot. I also have a copy of the drive / software (Bluescsi image - used initiator) if someone needs a copy. I'll check my software / cards...

    Mac Color Classic analog board crackles/whines/sizzles/hisses w/ video

    Is this a crack in the casing?

    Mac Color Classic analog board crackles/whines/sizzles/hisses w/ video

    Sounds like it might be your anode cap or flyback are leaking. It could be your anode cap isn't secured/seated properly. That or your flyback might have a crack. Put it in a dark room and see if you see any arcing. You recapped it so i'm not going to give you the whole spiel about monitor...

    Is there a way to turn the monitor off, but leave the logic board active on my SE/30?

    Thats how i'd do it. It'd be easy to toggle a relay with a single push button. The easiest way, obviously, would to just install a toggle switch into the expansion cover (on the bracket) and run two wires to it. That wouldn't be any fun though.

    Is there a way to turn the monitor off, but leave the logic board active on my SE/30?

    A relay to toggle the 12v on/off then. I, obviously, haven't looked at the circuit yet

    Is there a way to turn the monitor off, but leave the logic board active on my SE/30?

    That should be fairly easy to do with the power supply being seperate from the analog board. Just isolate the 110v going to the monitor circuit with a relay (so you could toggle it on/off). The trick would be doing it unobtrusively.

    Macintosh IIfx logicboard recreation

    I'm not sure if they're requiring you to get 5 or not, but If so I'd be interested in one if your selling the extras. If not, if anyone has a spare iifx reloaded pcb they want to sell lmk.

    Mac Plus not recognizing BlueSCSI after recap of analog board

    At this point I would check my termination power and verify my bluescsi with a different one. Also... make sure your formatting you sd card correctly (exfat or fat32) and see if you can put a blank hda in it and install to it from floppy (ive had bad sd's that wouldnt format correctly). If your...

    Mac Plus not recognizing BlueSCSI after recap of analog board

    Oh. And verify all your voltages are good coming from your analog board

    Mac Plus not recognizing BlueSCSI after recap of analog board

    If that's the case you either have a scsi issue or bluescsi issue. I haven't seen a bluescsi hardware issue (as of yet), but I've had a number of scsi issues. I take it you've done the diode mod for scsi termination since the bluescsi was working before. First thing I would do is try another...

    Mac Plus not recognizing BlueSCSI after recap of analog board

    I'd try reformatting the sd card and putting a fresh copy of your drive on it. I've had this happen to me a couple of times and this solved it (my bluescsi not booting that is)

    Hootswitch, a (work-in-progress) Apple Desktop Bus switch

    This is a super cool project! I've been wanting to have some sort of kvm for a while for my different machines. It looks like you've got the 'K' part sussed. I'm definetly down for building one once your happy with the finished product. Thanks!!!

    AppleSoft ROM Errors

    The built in self test you ran confirmed all is good.. it makes sure all the checksums are correct. You can use the other programs to test peripherals, but because they were written before 2e was a glimmer in apple's eyes the checksums weren't included. I'm not sure if there is a diagnostics...

    AppleSoft ROM Errors

    Your machine is fine. Your using apple 2 plus software to test an apple 2e. It might run fine (that was apple's goal after all), but the rom checksums they used weren't the same.
