After replacing two stock PS's in my Dual 1.25 MDD I installed an ATX PS. It's been working great for several years.

What a great trove! Especially the Lisa/XL disks. Quickmail, that takes me back. I still have work emails from the mid '90's in QM format. I don't know know why.

I believe the base base part does. The original PS's for these were 10v 1a.

I remember Doom II ran great on my 840av Quadra. With the Simpsons mod it was absolutely hilarious!

I have one. I did a thread about it when I refurbed it back in ~2018. I never did get the floppy drive to work.

Back in the mid 90's when I was working weekend night shifts at Motorola I spent hours playing TM on the SE's and IIci's we had in the office.

Don't know if this has been posted before. Tells the story of the ill-fated Lisa.

Good God! Hopefully the family will have the time, resources, and willingness to properly sort through all that and get some of it sold off properly. I'm sure ~90% will be sold by the pound but hopefully they can see some profit from the remaining 10%.

I'd like that too. :) I've done a bit of searching but found no good leads. I figure if it can be done some one here will know how.

So I have a Profile HD that I use to run my Sun Rem Lisa 2. Is there a way to connect the Profile drive to my Mac Plus and read/write to the Profile drive? The Profile drive is parallel I believe so I need a Parallel to scsi or parallel to serial adapter?

Very ambitious project! I hope the CPU card goes well.

Does the iBook have the latest firmware? Might try resetting the PRAM as well.

That made me laugh! From Wikipedia: "A/ROSE is infamous for its esoteric purpose, which is generally not understood by Mac end users, as well as for causing many Mac emulators, such as Basilisk II, to produce a system error at boot time." I think in all the years I've used Macs I only ran...

Thanks, back in the day I had it loaded up with four HD's and two optical drives. No wonder the original PS gave out. (twice) I pulled out two of the HD's and an optical drive after the second OEM PS died. It's a dual 1.25ghz system. My intention was to over clock it to 1.42 but I never got...

I did the ATX power supply swap on my MDD a few years back. I got a molex pin extraction tool and swapped the pins in just a few minutes. I used an ATX PS extension cable to route the lines behind the optical drives and clear the full-length nvidia card. The PS is held up with a couple of sheet...

Looks like it drove an Agfa image setter. Just casually googling around, seems like there might still be a (small) market for these. You should a bit more research before you declare it worthless.

(Oh, yeah, ^^^^^what he said.^^^^^^) Hmm looks like at some point they made some 182 pin versions as opposed to the more common 179 pin packages.

You are correct. I misread that portion.

I ran your serial number over here and got this. https://everymac.com/systems/apple/powermac_g4/specs/powermac_g4_1.25_mdd.html Your system may have the same board but different firmware or the description of the system capabilities is incorrect from one of those sources.

Based on the serial number I believe this model will only run OS9 in the "classic" environment. i.e within OSX. (Tiger) This is the "rereleased" G4 version that Apple sold for a while after people complained about dropping OS9 support.
