    Dead SCSI bus anomaly on old Mac's

    Ok, so, I'd like to bring this subject back up again. So far now, my Macintosh Plus, SE, Macintosh II, and now my Macintosh IIx are affected. What's happening is that one day these macs just start refusing to boot from an external SCSI HD or CD-ROM. Re-capping the logicboard does not help with...

    Powerbook 180C Wont boot from SCSI

    Hello again. My 3rd problem of the week so far lol. Now my Powerbook 180c will not boot from any external SCSI device. Whenever I hook a SCSI cable up to it(I have 3 of them), it wants to boot instantly into SCSI disk mode. Is there a way around this so I can reload the OS?  I don't remember...

    Macintosh SE/30 clock not working / time not advancing.

    I've seen a few hits on google with different machines where the RTC doesnt work anymore, but nothing about the SE/30. My SE/30 boots up and runs, but the time will not advance on the clock. I've replaced the PRAM battery, what could it be? Thanks

    Color Classic not powering on. Makes a chirping noise

    Hey there. I've got a Color Classic that no longer wants to turn on. When the switch is flicked, you can here it it energize or whatever you want to call it, then when you press the on button on the keyboard, it tries to turn on, then makes a chirping noise and shuts off. I've re-capped most of...

    Powerbook 520/540c Power Adapter repair/re-cap

    Ran into an issue where my power adapter for my Powerbook 540c was outputting 16v on one pin, but only 2.xv on the other pin so my 540c would no longer start up. Took the PA apart(it's epoxied together) and discovered 6 capacitors. 2x 330uf - 25v, 2x 100uf 200v, and 2x 100uf 25v. The part...

    Color Classic G1 pin locations?

    Got a Color Classic logic board here that has a bad thru hole connection. Looks like someone did a nasty job at trying to clock chip it (can't be done this easily on a CC) and reamed one of the holes out. Does anyone know where the 4 pins at G1 go to? Thanks!

    SCSI anomalies on all my older Macintosh's

    Been awhile but I've been having strange anomalies on almost all of my older macs. From my Plus's to my 9600. For instance, my Macintosh Plus's will no longer boot from an external HD. It doesn't matter what HD, or what enclosure I use, they just sit there at a grey screen. My 9600 will no...

    SCSI ports not working on 3 Mac Plus's, confused.

    When I was boxing things up to put stuff in storage, I dug 3 Mac Plus's out of a closet and tried to turn each one on. One by one, they all turned on, and came up to the blinking disk icon with the question mark. I thought "okay, at least they all still work". So, I hoped on my 9600 and quickly...

    WoOt! I won one of the items I have been looking for, for a while. 1 used Powermac 6360 for $36.65 ;D Hopefully it arrives in good shape, but so long as the powersupply functions, I dont really care about the rest at the moment. Next is a Powermac 6500/300 Logicboard replacement for it...

    Need opinions, dead 9600/350

    Hello again. I am still searching for a reason as to why my Kansas 9600 logicboard bit the dust a few months ago. I ran this machine since new, almost 12 years(or more) of service with no issues at all. Installed a 36GB Seagate SCA drive a few years back with an SCA to 50 pin SCSI adapter...

    6200 Overclocking procedure?

    Hey, does anyone have the procedure to overclock the 6200 motherboard from 37.5mhz bus to 40mhz? Takashi's 6xxx overclocking site hasn't been around for awhile( http://www.bekkoame.ne.jp/~t-imai/pm52e1.html ) so I was wondering if anyone might have backed up that site to disk, or remembers just...

    Hello!

    I don't know what to say.... a forum devoted to 68K Macs? I think I have found heaven on the internet. :) I really don't know what to say, ummm... err... I'm a long time Macintosh technician, my exp. dates back from the early to mid 90's and I use to know just about everything Macintosh...
