@ttb I Actually experienced this same problem. I have a few 040's and a P33 and P34 cache. Tested all the accelerators on my iisi, so I knew they were good. The symptoms are exactly as you experienced, and IIRC the P34 worked fine. (I was playing with this back in January, so the exact details...

@TweedyF Sorry to see that.. I also have a board that was nuked that badly. I thought I could bodge the crap out of it and make it work but the traces underneath were too far gone, I had to grab a spare good board off of ebay to revive the mac.. Excellent parts donor though. Twist off all those...

Yep. The second pole of the switch does that. If you look at the photos and then the schematics, you'll notice that there are two jumpers that have been replaced with wires to the switch. :)

I have actually recapped the PSU and Analog board... The inrush current to all the larger value caps on the Horizontal/Vertical circuitry is what causes it to brown-out for a second. A diode and a some larger caps on the logic board might fix this, but I found that powering off the buffer chip...

@techknight Thank you for the help! I'll add those in.

I tried that first, actually. Switching it back on made the logic board brownout and reset. You are probably right, let's add those. Can you show me where to make those mods and I will add it to my original post so we can make the mod better? Side note- I thought about using a piece of...

@Bolle I have two GAL T040's that I just can't seem to get to stay stable, and aim to do the MacCon -> Short Adapter + T040 -> iisi Pivot combo.. I have a few 74*68 chips laying around, and your ProtoCache1.1 short adapter I can modify. What are the jumper settings I need and besides the...

Good questions! Yes, you  will have to cut the case and some of the inner metal chassis. ...but the SE/30's are so awesomely hackable, why not? If you wish to run it as a server, the switch is fairly inconspicuous. As for the reasoning... (besides bringing power consumption down to 34W from...

Hi Everyone, I would like to present my SE/30 monitor on/off switch. It's only a matter of removing two jumper wires on the analog board - W4 and W5 - and switching each of them on either pole of a DPST switch. (With optional LED, DigiKey P/N CKN2068-ND). Full instructions and more photos here...

I’m not sure, but as far as I’m concerned an open-source route is the way to go!

This is great, especially for those machines where it’s near impossible to put a NiC in, like my Macintosh portable!

I want to chime in on the OpenWRT/Vonets discussion- I have found that the Vonets is quite finnicky. A solution that incorporates a device running OpenWRT will be way more functional. Heck- I believe that you can even install it on a Raspberry Pi.

You are awesome! Put me down for two as well please!

Nevermind... I needed to ground pin 4 to 11 (C&VSYNC.GND) and not pin 1 (1 RED GND/Chassis)! http://old.pinouts.ru/VideoCables/MacVideoToVGA_pinout.shtml ...In case there's anyone who also has this issue.

Hi Everyone! I am trying to get my 'AppleColor High-Resolution RGB Monitor' (M1297) working with my SE/30 with a hacked-in IIsi pivot. It just doesn't want to detect it... However if I first connect a VGA monitor through a Mac to VGA monitor adapter, let the computer boot, then switch over to...
