H3NRY, I'm using a 7.5V supply at 2A. Would that be sufficient, or should I go for a 3A one instead?

What's the average lifespan of an SE/30 Analog Board after it's been put under that kinda load, BTW? Click to expand... Since the SE/30 has a PSU separate from the Analog Board…

Course, the SE/30 was never designed to take a Nubus card. Presumably this also means any back panel connector soldered directly to a (Nubus or IIsi-only PDS) card will end up buri…

Look at Von's diagram: (click to embiggen) His Ethernet card and Daystar adapter both work in either the IIsi or the SE/30. In both cases, cards added to them mount over the mo…

My campus is on spring break right now, but I may be going in during the week to set up our Mac mini server. I'll try out the battery idea. Any idea for a Titanium PowerBook G…

Don't know. I started tracing out the power supply of the beast, but haven't got it figured out yet. It's pretty complex with stuff feeding back on itself. If anyone knows of a sch…

It would be nice to have, but at what cost?

What's the story with the custom voltage regulators, and can an off-the-shelf part be substituted?

The "lisp co-processor" runs its own operating system called "Genera" which is dramatically different from windows/unix derivatives like osx and windows. The operating system is to…

If you want to boot one without a good battery, you need a later PowerBook AC adapter, one that puts out at least 2 amps. I use a model M5652, which is 3.0 Amps at 7.5 Volts. It's …

I don't think it would collide with the tube if the floppy drive in particular weren't in the way. It might well do that if attached to the riser card pictured, however. Click t…

It could well be the power manager. You can reset it - I forget the key combo, but perhaps Apple's support pages have the info.

When I jiggle the power plug in the back of the powerbook, the socket feels a bit loose. It worked well all afternoon today after I did that....I think my son in his enthusiasm has…

I didn't take the PRAM battery out. Will a dead PRAM battery keep it from booting? Click to expand... Yes it will. Unplug it and it should boot up when you press the power bu…

I didn't take the PRAM battery out. Will a dead PRAM battery keep it from booting?

Actually, I take that back. It looks like a power problem. After the two-fingered power manager reset, I can get a pointer to appear, but as soon as it tries to spin up the hard di…

Mine might be bad cappy. I'll investigate. Right now it just clicks, but won't boot.

I second this suggestion. Worked for every pismo I had that did not turn on.
