    Some new SCSI2SD problems

    Probably best to start a new thread rather than bring one back from the dead.

    Fingernail Polish to protect exposed copper?

    Down side to superglue is it breaks down at around 100c. So don't expect to be soldering around in it.

    Fingernail Polish to protect exposed copper?

    You can pop the rivet out from the back side by pushing on the center. or from the front by getting a screwdriver in between the top of the rivet and the next layer. You should probably discharge the CRT before doing anything else inside the chassis to avoid shock. I can't speak for the nail...

    Is this disk salvageable?

    You'd probably have to use a flux imager to have any possibility of recovery.

    Dumb AppleTalk Question: Networking Classic and SE

    You mention a serial cable. I believe you actually need local talk adapters not just a serial cable between the two computers.

    Very neat potential solution for our 30-pin Macs and wanting ALL THE MEMORY

    Flux only needed to resolder. Removal with hot air would just be hot air evenly applied and a pick tool to give light lifting pressure. Or you can buy some chip quick rework solder and use an iron instead of hot air.

    Very neat potential solution for our 30-pin Macs and wanting ALL THE MEMORY

    I wonder if the viewer got them on Alibaba or something like that. You could also remove the chips from 72 pin versions. If you search for DRAM 4mx4 on ebay a few sellers turn up. You'll want to verify foot print and package match the Gerber's.

    The disk at SCSI #0 has been remove while in use

    So far I found two files. I'll see if either are something I can share. One is an old FileMaker database that may have private information in it. The other seemed to be in the preferences folder. So far I have been stuffing the whole hard drive and it's going on 10 hours with no issues. It...

    Macintosh Plus - Repair Help

    I've not used a PICKIT to flash EEPROMs. But using a TL866 family of programmers isn't hard assuming its a supported chip. The basics would be to convert the raw file into a format used by the flashing software. After that load the chip and write then verify. If your reading the ROMs from...

    The disk at SCSI #0 has been remove while in use

    Normally my Mac Classic II works just fine. But if I connect up a spinning disk to the external port and attempt to copy a large number of files off to the internal SCSI2SD I get the error message "The disk at SCSI #0 has been remove while in use" and the SCSI2SD disconnects. I end up rebooting...

    Apple IIe Disk card ID needed

    So I attached the floppy. No disk access. I removed the cards added some Deoxit and reseated one at a time. The disk drive started working. I put things back together and it stopped. It was then I realized the problem was a Corvus Systems Transporter Apple card in slot 7 seems to make the disk...

    Apple IIe Disk card ID needed

    I haven't tried the disk drive yet as I have no formatted disks. When I try the Floppy Emu I see no attempt to read the disk but I don't know if I'm selecting the right drive type. Does the controller need to be in a specific slot? I came in slot 6. In slot 7 there is a network card.

    Apple IIe Disk card ID needed

    I recently acquired an Apple IIe. I'm trying to get it to work with my Floppy Emu but not having much luck. That said I don't really know what I am doing when it comes to Apple IIe. I last used one back in the 80's when I was 10. The Apple IIe seems to startup fine. Self-test checks out. I put...
