  1. I assume your external Scsi2sd is terminated right?

    Wiki/Pages article ideas

    Yes! And any PCB designs folks have put together, like this cool Mac Plus internal scsi mod.

    Adding Wi-Fi to my Mac SE/30

    I use the same extender, it's a great and easy solution. I threaded it through the security slot and use a velcro dot to stick the "stub" card reader thing to the rear of my SE/30 case. It is slightly annoying when you open the case, though ... that ribbon cable isn't super long.

    Color Classic Fan

    That’s right. Actually I soldered the stub wires and the snipped fan wires to a pair of 2 pin connectors in case I ever wanted to swap out the fan again. I don’t recall why I chose the FLX model, it was a while ago - maybe just because I figured I couldn’t use the PWM feature anyway? I’m not sure I remember noticing that RPM difference.

    You are correct. I have replaced these with a Noctua NF-A8 FLX in the past, clipping their third wire.

    SE/30 + AppleCD unimplemented trap

    What version of the AppleCD driver are you using? If not already, try using the one linked here: http://main.system7today.com/updates/75x_68k.html

    Very perplexing SE/30 MB ADB issue

    Legacy Macs update the cursor position and redraw the cursor during the vertical blanking (VBL) interrupt when the CRT beam does a vertical retrace back to the top every 1/60 second. This literally interrupts the 68k CPU, which is why you can almost always move the mouse pointer even if software gets stuck or crashes (the exception is cursor movement slows during floppy disk access, which disables interrupts). On the SE/30 IIRC the mobo learns about VBL interrupts when the video circuitry informs VIA2 which informs the 68030 (see Guide to the Macintosh Family Hardware, look up vertical blanking interrupts in the index). I was surmising that if a trace got wonky near your VIA, you could lose cursor movement. It’s just a wild ass guess though, but I’m reaching because I agree that an ADB fault that only affects cursor movement but not clicking or key presses sounds unlikely. I’m more of a software guy so I’m guessing others will have better ideas where to look for your issue on the board though.

    Sounds like your ADB might be fine. Random thoughts- Cursor movement is handled at VBL interrupt time. Is it possible when your cap blew something got damaged between your video circuit and the VIAs?

    Price Check: Classic II

    No PDS at all on the Classic II though right? I assume one could upgrade an SE FDHD to beat the performance of a Classic II using an 030 upgrade.

    What a fun mod. Thanks for sharing that.

    Checkerboard Pattern on Mac 512

    Pretty sure those are custom ROMs from an eBay seller I’ve bought from before. If so they’ve been legit in the past but do try reseating them.

    Checkerboard Pattern on Mac 512

    Sorry, what is that upgrade board on the left? From the other thread, were you guessing that’s a 512k upgrade to the 128k motherboard? How is it attached? What happens if you remove it? Just curious ....

    My compact Mac-themed birthday party

    Sorry about the Plus but this is still amazing. Happy birthday!

    Asanté MacCon SE/30 clone

    OpenWRT is awesome. Among other things I believe the Vonets device doesn’t support 5GHz WiFi at all, does it?
