    Powerbook 3400c CD-ROM Drive

    I repaired the catch mechanism of the CD drive, the drive wasn't staying in the chassis anymore, just popping out. the little spring loaded lever would not return to a straight 90 degree position and therefore not catch the chassis. you must disassemble the parts to get to the bottom and clean...

    BlueScsi CD images

    I now tried to add a OSX Jaguar CD to the sd card but it doesnt work, maybe sheepshaver/Bluescsi only works with classic OS up tp 9.2., but not OSX. :unsure: When I add the Jaguar iso in sheepshaver preferences list, it appears on the sheepshaver desktop, I even can see the OSX installer files...

    Kanga Ethernet on OS X Jaguar

    oh, I wrote 604e above, I meant 603ev of course. Your distro, I mean which exact Jaguar CD ( link) did you use? I used the 2 CD version here ,14,15. I couldnt get it to boot further than the above mentioned line, so I took the chance to upgrade my 9.1 up to 9.2.2. wasnt easy to find the correct...

    Kanga Ethernet on OS X Jaguar

    so just for fun I tried it yesterday evening with my 3400c( with 144MB Ram), so no G3 here, and as you will know, the XPF homepade has some problem notes for the 2400/3400/Kanga listed there: I used XPF 4 for that, so my 604e only can work with 10.2 (10.3 and up only with G3 and G4). I have...

    Kanga Ethernet on OS X Jaguar

    I remember having read here several times that OSX 10.2 is making problems, I would use it with 8.6, 9.1/9.2.2 https://68kmla.org/bb/index.php?threads/best-os-for-kanga.41562/

    Just overclocked my Pismo

    its a bit of a trial and error with the G3.. my 3600Mhz iBook Clamshell did fine @400 Mhz from 366Mhz, but I guess not higher

    Kanga Ethernet on OS X Jaguar

    if Ethernet doesn't work there's obviously something not right with the XPostFacto install, builtin Ethernet should be recognized. is the connector on a little daughterboard?.. maybe its loose a bit.. I only have one working SCSI Ethernet card, 3Com EtherLink III, but it is 68k based, works...

    PB 2400c ram

    thats a lot of valuable info ..reading through the two PDF I wonder how you would compare the form factor of a 3400c RAM expansion module ( has only one side populated) with that of a SO-DIMM 😳..and the connectors maybe a new interesting community challenge..as there is obviously a demand...

    PB 2400c ram

    ok, little update on the RAM, I bought an IBM branded, 64MB, EDO SO-DIMM 144-pin 60ns 3.3v stick, after boot in 8.1 only half of it, 32MB are being recognized..ok, better that before, but still strange. ( I cleaned the contacts three times). I asked the seller and he just went with the...

    Coolest 68k Powerbooks to own?

    having restored a 540 and 540c I must say these are nice machines, but the 190cs is evenly good imho..ok, the design factor comes in and there the 540 are great. I wish the 190 had internal ethernet but a the 3Com Etherlink III pcmcia card still does a good job. This card works best witj older...

    PowerBook 190 revival

    I also tried to replace the original quarz crystal to a 20Mhz one but it didnt work, maybe its not the correct crystal.. rechecked the soldering three times but it didnt get better, then I resoldered the original quarz back and it worked again. The 5300 also had a RAM expansion card in...

    PowerBook 190 revival

    did some updates on the 190cs, I got a bombed 5300c mostly for parts for the 190..display, graphics expansion card for external, intfrared assembly, original working powerbrick and the back door. The 5300 chimed but never attempted to boot, the board has corrosion on many places, as I dont need...

    PB 2400c ram

    its confusing, EDO Ram basically belongs to DRAM, all 144pin, not compatible with newer synchronous SDRAM, ok. EDO came in different packages, some ( as mine above) with 28 pin footprint, others with 32, but all EDO Ram run on 5V, not 3,3V. so, maybe these 32pin EDO can run in the 2400c?

    PB 2400c ram

    ok I did a dis- and reassembly of the machine because I wanted to take a look at the actual RAM thats installed, remove the pram battery and replace the HDD with a SD/IDE card. I guess the encircled two yellow cables are those for the PCMCA/CardBus mod? ( this model is the 180Mhz model)...
