    Performa 631 Compatible IDE to CF Adapter

    I'm a bit stumped.  I am trying to replace the original, and failing, 500MB IDE hard drive in my Performa with an 8GB CF card.  I've tried two different IDE to CF adapters with no luck so far.  Each time I use Drive Setup, both versions 1.5 and 1.7.3, patched and unpatched, I get an...

    What A Wonderful Morning!

    Thanks everyone for your comments! ROM is in socket correctly.  That's why I triple checked ;)   I wanted to be sure I had it not only oriented in the correct direction but in the proper socket pins.  @techknight I'm afraid you're right.  I didn't perform the recap of this machine, I bought it...

    What A Wonderful Morning!

    I've double and triple checked to make sure the ROM is seated in the correct direction.  I'm thinking one of the capacitors may have not been soldered correctly.  I bought this computer recapped before I worked up the courage to recap myself.  I'm going to go back over each of the capacitors...

    Quadra 630 ATX Adapter

    As a new owner of a Performa 631 (I'm jealous of your DOS card) I'll be keeping an eye on this thread.

    What A Wonderful Morning!

    Board swap with my functional Classic worked.  So the problem lies somewhere on the logic board.  I swapped ROMs and the same issue appeared.  Same garbled screen.  Interestingly enough if I pull the memory expansion board/ram I get a very defined checkerboard on the screen.  Dead Mac Scrolls...

    What A Wonderful Morning!

    1/2 good news.  Reseated the ROM of the Classic II.  It's happily starting up now.  The Classic however, no such luck.  I pulled the ROM, gave it a conservative wipe down of deoxit and reinstalled.  Same issue.  @bibilit voltages check out, 5V is at 4.97 and 12V is at 11.97.  I doubt my...

    What A Wonderful Morning!

    I'm in the processing of diagnosing a floppy drive on a Classic undergoing repair that fails when trying to initialize a disk.  I figured it'd be good to see if the disk was any good so I pulled out my Classic II that I recapped last year: Super!  Well, let's not ruin the morning, how about...

    Classic External Floppy Port Issue

    I had planned to replace the drive with a SCSI2SD unit from the beginning, it just happened to work out for troubleshooting.  End result is I have a completely recapped machine that is now rock solid.  I've been running it for at least a couple hours a day. I did discover that the speaker is...

    Classic External Floppy Port Issue

    Update: Finally got a bit of free time to devote to this computer.  Turns out the hard drive was failing.  Drive has been replaced with a SCSI2SD and everything is working great!

    I am so glad I found this forum.  All of these projects amaze me and I love seeing an idea come to reality.

    Classic External Floppy Port Issue

    After some additional testing, HD20 emulation works fine through the external floppy port.  Floppy emulation fails at the external port regardless of whether or not I have the internal floppy drive connected to the logic board.

    External FDHD Superdrive thinks disks are write protected

    I'm working on a Classic right now that is experiencing the same issue.  Thank you for the tip!  Was the switch stuck and the oil helped move it or do you think the contacts inside were the problem?

    Well Crap (SE/30)

    I've wanted to try out Evapo-Rust, the gentleman over at Hand Tool Rescue on YouTube (another great channel) seems to like it.  On the other hand, I've got a couple friends with media blasters so I may just go that route.  I'd really like to explore chrome or nickel plating, chrome is not going...

    Classic External Floppy Port Issue

    As I alluded to in my SE/30 thread, I'm also working on a Classic.  I've running into an issue when plugging my FloppyEMU into the external port of the computer.  When in floppy emulation mode, I am able to select a disk image but the moment the computer begins to access the image, my FloppyEMU...

    Well Crap (SE/30)

    I just watched his video last week.  I may give that a shot if the board is dead after the recap.  I'm a little worried that the WD40 might eat away at more than the corrosion.  That was a great video series by the way.  Highly recommended for anyone who hasn't watched them yet.

    Well Crap (SE/30)

    Thank you @davidg5678 for the links and the schematic.  Both will come in handy.  @Bolle great plan, I'll recap the board and give it a shot before throwing parts at it.  I should have enough spare caps.  Updates to follow.

    Well Crap (SE/30)

    This is the damaged section of the logic board after an initial rinse and dry.  Still not sure what goes in D1, D2 and Y1: And a before beauty shot of the chassis: Still plenty of work ahead of me.  Hopefully the floppy drive will have survived.  I've got a Classic that I started on before...

    Well Crap (SE/30)

    Thanks for the words of encouragement!  Board has gone through an initial rinse and scrub.  I'll be going over everything with deoxit this weekend.  I have a few missing components near the battery damage which I will need to identify and replace: D1 and D2 are diodes (I think) would anyone...

    Well Crap (SE/30)

    So far I've been lucky and have dodged a bad battery so I'm just disappointed that my SE/30 was the one to suffer the damage.  I'm definitely going to start looking for a place to do nickel plating once I've done the clean up. Updates with photos are sure to follow.

    Well Crap (SE/30)

    I finally got brave and cracked the case on a SE/30 that was given to me.  It had been sitting in a hot garage for a number of years. Needless to say, maxcell bomb strikes again.  It was getting dark so I don't have any more pictures.  The chassis is pretty bad too.  I'm inspired by...
