    Quadra 840av Cold Boot Time

    Yes, more ram will increase startup time. In OS9 you can disable the startup memory test. I think that same option is available in 7.6.1. https://happymacs.wordpress.com/2015/01/30/speed-up-mac-os-boot-time-turn-off-ram-tests/

    Always feels like Christmas when you find an unexpected accelerator card

    Neat find! Fully loaded! Someone paid dearly for that package "back-in-the-day". That's an old '030. 1988

    Anyone Recognize This Weird OS On This Proto Mac mini?

    One of those grey labels says Foxconn so these were used for testing components or perhaps inventory tracking, if the GL50B means anything.

    Anyone Recognize This Weird OS On This Proto Mac mini?

    Huh, fascinating. It looks like Chinese to me. Lots of stickers, like they were used for a long time and/or passed around. Where did you come by these? Also, maybe just a coincidence but there is a device called GL50B GPS asset tracker. I wonder if these were used as a test/programming station.

    Anyone Recognize This Weird OS On This Proto Mac mini?

    That blue and white sticker reminds me of Motorola inventory/property tags. Have you translated the text on the other stickers?

    MDD Power Supply options

    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.

    Macintosh, Lisa, and IIGS Dealer and Developer Floppy Disk trove

    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.

    Apple PowerCD issues

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

    Porting LinuxDoom to System 7 (or trying to) - progress and questions

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

    Macintosh XL, anybody?

    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.

    New version of Tetris Max

    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.

    Interesting short documentary about the Lisa.

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

    Local estate find in San Diego

    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%.

    Connect Profile HD to Mac Plus?

    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.

    Connect Profile HD to Mac Plus?

    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.

    iBook Clamshell - Only Detecting 64MB of 512MB RAM Stick?

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

    What is the SWIM PIC?

    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...

    does anyone make a atx to MDD converter

    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...

    does anyone make a atx to MDD converter

    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...
