    OS X Developer Preview on Pismo?

    I installed 10.1 on my G3 Kanga ( with max 128MB RAM) via XPostFacto but it wasnt fun..it basically ran but without Ethernet. there still is a difference between a Wallstreet-to-Pismo and a Kanga architecturally

    ...well

    ..technically speaking it is working.. :LOL: sticker on the 603e and has some wires soldered, seems stock threw in an old RAM card from another blown up 5300 in which it didnt recognize that card..in this machine it now sees 49MB, guess its 52MB..36MB card with the 16MB onboard.

    PowerBook 2400c x 2: GLOD city

    ''.. Stripped down @finkmac suggestion to absolute barebones just components mounted in the frame, no PRAM, no secondary RAM, speaker, and a sketchy heatsink perched on the CPUs - both chime immediately without power switch needing to be triggered. Switched CPUs around to how they came (noting...

    PowerBook 2400c x 2: GLOD city

    I really wonder why so many of those 2400 CPU cards fail, why components cant be replaced..so unreliable

    Pismo G4 550Mhz Upgrade, overheating issues

    ok, thats cool..from what I've read it depends very much on the individual sample of a G4 you have if you can push it that far.. not tried that. that, additional fan inside the ( emptied) DVD drive, and when this works, maybe just add a little horizontal poti to turn it down or up. I'd look...

    Pismo G4 550Mhz Upgrade, overheating issues

    the pismo was a quite capable G3 machine back then, fanless..but a G4 is quite another thing heatwise. I guess you did some research on that mod and experiences with it before? may try to get something like this working in the CD bay?

    SE/30 battery bombed repair attempt

    maybe the quarz crystal got damaged during the multiple ultrasonic cleanings, or was it removed before that..

    Macintosh PowerBook 1400cs/166 - Power Issues?

    did you get the replacement Schottky yet? I guess you already tried connecting the power adapter and power on with pressing Control+Command+Power and immediately reset the PRAM on the first sound.

    Macintosh PowerBook 1400cs/166 - Power Issues?

    make sure the CPU,RAM and ROM boards are seated in firmly..do you have a spare CPU, maybe it is dead. and when the Schottky was dead, something was causing this.

    Powermac Quicksilver 2002 keep overheating with Fastmac 1.4 Ghz card

    to check if it is indeed a thermal problem I would run it full speed with the case opened, then do some stress tests. If theres no problem, it is heat related. I once build a HackIntosh from my QS with an Gigabyte M-ATX board, 450W power supply and a GeForce 7600GT in it. Did cut some extra...

    Solid-State Drive Options for PowerBook 1400?

    thats the thing I was thinking,too.. and yes, my 1400/2400/3400 work with CF cards and adapter,too..but I sometimes prefer to use a new(ly) good IDE drive instead. so install back the IDE drive and after boot pop in a CF card in the PCMCIA slot and see if it is being recognized/formatable

    Oh, the 540c, I misread, sorry, I thought you meant the 5300. On the 540c I did a repaint job, it‘s a 540c black coffee edition now😏

    5300c revival

    try to identify the original quarz, I'm not sure what the specs are, 3V or 5V.. it seems to be a vintage Epson part? but the small label on it is also on Seiko crystals ( of course the package size and footprint are different) original quarz Epson Seiko
