I'll admit that I don't have a solid handle on the theory behind tantalum derating, but the general rule of thumb seems to be that the steady-state voltage across them should be no more than 50%-80% (depending on who you ask) of the rated voltage. So at best, 12 V is cutting it a bit fine, and...

Sorry it took so long getting back to you, I only just found the breakout cable for my card! Pins on the ColorBoard connector are numbered as follows, looking at the component side of the board with the PDS connector to the left: -------------- | 2 4 6 8 10 | | 1 3 5 7 9 | ------...

So, the other day, while I was using it, my SE/30 experienced rather a dramatic failure, dying with a sharp "snap" and a smell of burning electronics. I'd recapped it about a year ago with tantalum capacitors, but I hadn't touched the (Sony) power supply or analog board, so my first instict was...

Huh, interesting, I’ve got a Unifi switch (an older 8-port, can’t remember the exact model) between my vintage Macs and a Netatalk 2.x server and as far as I’m aware it’s never been any trouble. I’ll have a poke around and see if I can find any options that might affect it.

For what it’s worth, I have an ADC Cinema Display that’s always had a similar problem. Sometimes the ports work, sometimes they just never get recognized, sometimes they cause an overcurrent warning. Even happens when plugged into a non-Mac via the big DVI adapter brick. I’ve taken to just...

At least in my case, the 'monitor' that shows it most noticeably is an Extron RGB-DVI 300 scaler - they're pretty cheap, smaller than a monitor, and handy to have around in general, so that might be an option. On the Extron it shows up as a bit of smearing and/or static horizontal displacement...

I'm not sure how useful this will be since I don't have a Sync-inator, but thought I'd chime in, since I see something similar on the output of my E-Machines Futura SX connected to a modern video scaler with an adapter in separate-sync mode (Mac pins 12, 15 -> VGA pins 14, 13). I put my...

Yeah, I need to do a bit of thinking and experimentation here. It doesn't have to be too precise a delay, but if it gets too long, it will start to impact timing of the rest of the bus cycle. I haven't done the math yet, but I think 1-10ns is what I'm aiming for. I was thinking along the same...

With my SE/30 out of commission until I can find replace whatever went bang in its power supply, I thought I'd turn my attentions towards the long-neglected SE version of the ethernet card. My first attempt revealed a fairly glaring mistake in that I'd got the PDS connector pinout backwards, but...

Sure! I've got: Input Configuration: Pixels: Total 1456, Phase 9 Start: 100 H, 130 V Active: 1152 H, 870 V Picture Controls: Position: +64 H, +77 V Size and Zoom both 1152 x 870 Output Configuration will depend entirely on your monitor. Leaving everything set to Auto worked for me. That...

Yeah, the installation situation is unfortunately a bit complicated. The driver for the SE/30 card can be installed drag-and-drop into the Extensions folder, but only if the EtherTalk Driver from a late (1.4.x or 1.5.x) version of the Network Software Installer has been installed previously...

Oops! Thanks for the correction! Mods - any chance we could remove the mention of the 165c from the title just to avoid misleading anyone?

I finished recapping the display in my 180c the other day, with great success, and while I know there are capacitor lists for it out there, there didn't seem to be any references for suitable sizes/footprints for the replacements, so I thought I'd share my notes on what worked for me...

I've been doing a bit of investigation of BlockMove as well, while trying to squeeze more performance out of my ethernet driver - in particular, I've been looking at BlockMove versus the newlib memcpy() implementation in Retro68. I wrote a quick and dirty benchmark, moving memory around in...

Powered on my long-suffering SE/30 this afternoon and something went "bang." Time for some power supply surgery, I suppose.

Can confirm, the RGB-DVI 300 works beautifully on my IIfx with an E-Machines Futura SX. With a bit of fiddling I've got it displaying 1152x870 at 1:1 on my 1280x1024 Dell LCD. Looks a LOT better than being scaled up! It's also very nice that by default it saves configurations per video mode, so...

Ha, yeah, good point. I noticed that the install script from an Asante driver disk I looked at has a bunch of 'dead' rules related to an A/UX driver shipped on Apple's Network Installer disk, despite the fact that they don't include any A/UX drivers! Huh! I'd looked at MPW-emulation tools...

And with some rather hideous hackery, we have an installer! https://github.com/rhalkyard/SEthernet/tree/main/installer I DeRez'ed the installer script from Network Software Installer 1.4.4, and with a bit of reverse-engineering, crudely chopped out the Apple drivers and replaced them with my...

Yes, there’s supposed to be a breakout panel with a 15-pin monitor connector, with a cable that connects to the grey 10 pin connector on the card. I have the same card (a RasterOps ColorBoard 264/SE30) and have a note of the pinout somewhere if you want to make up your own cable. I’ll post...

Just saw this thread crop up, and I'm chiming in to say that I can reproduce this reliably on my network too. At one point I investigated a little and if I remember right, the bogus zone name was coming from the 'STR ' -4066 resource inside the Tardis extension that was supposed to be reserved...
