well done..nice! the display brightness and contrast also look quite good.. nice to see one of those rare 550 birds in working condition. the slightly bigger screen of the 550c is nice. the brighter grey plastics color scheme, yes it looks more like the 520/540..if the original state isnt the...

I just disassembled the old drive of my junk 3400c, the CD seems very different from the 1400, more squarish https://68kmla.org/bb/index.php?threads/powerbook-1400-cd-rom.31498/#post-462440

That is the 166mhz board? I cant remember seeing on mine that slim aluminium rail on the top of the board back..have to look that up

thats a really cool looking product/conversion kit..the inner innards remind me of much later iMacs as they also incorporated basically mobile architecture.

great job ..uh, I'd like to have a full 68040 in my 540c, not daring to dream of an even rarer PPC 117Mhz upgrade card.:cool:

It also just can be a dodgy install on the old hdd, I had strange errors/probs.. after a fresh install it was ok.

I wouldnt try out any hard chemicals on that old vintage brittle plastics..the weakening is much worse. If I wanted to restore this I would respray it with a vintage white spray color. And before that I would check how good that old black spray job was done.. meaning, looking for color run...

I dont think that would make a big difference, as long as it isnt slower than 70ns..I had my 540c board populated with chips of this funky looking ram stick..I chose this because it had slim type chips. they are now mixed, 2100 AT-6 and 2100 ALLT-7. here 32mB reference boards

can you post some photos from the insides? also from the powerboard.. here are some pics https://oldcrap.org/2022/05/31/apple-macintosh-powerbook-5300cs/ RAM is soldered onboard, 8, 16, 32 MB depending on model.

wow that machine has seen better days, I remember we had one of thsoe in our graphics agency. Good luck with the restauration, I really would recommend taking it all apart, cleaning it thoroughly, recap everything before usage. .. like Bruce on YT, it will be worth it. The sticky brown dust...

well, make sure the the shim sits correctly, otherwise alignment wont work. I marked the position of the old standoff holes with a silver marker before, so I was sure the new holes wouldnt be off. Then glue it down. Then I just put the brass standoffs on a hot soldering iron for 5 seconds and...

can you clarify what you mean exactly? is your question if the brass screw inserts are fully sunk into its correponding holes, touching the actual back of the display housing?Just compare how deep they are now, thats the height/position they need to be afterwards, otherwise the screws cant reach...

I had similar boot problems tinkering with just installing extensions of the 3com Etherlink III card on my 1400c..as soon as the drivers were installed it just wouldnt boot into 9.1 anymore just straight into the second 8.5 partition. I then learned that to always have a backup copy of the...

Have you cleaned the RAM sockets? I bought the cheapest pc133 512MB so dimm I could find on eBay/amazon and my Pismo 400 and 500 ran well..maybe you could update your Pismo firmware? I have found this on my Pismo CD, when you dont have the right (FireWire G3 PB) model, it wont install.)

external, ok..and what is installed inside the PowerBook? ..a BlueScsi?

does the Iodata idsc21-e look like that? how does that fit into a 520?

is the original old ide HDD still in it? ..maybe it is beginning to die and messing with the OS. you could try another drive ( or ssd) and try a fresh install and compare. I had strange install errors on dying drives

hm, I also had the 550Mhz Ti model, I thought they actually had a PowerPC 7440 with 256k backside Cache..but I also noticed they are quite slow.and the Ti's in general heat up quite a bit. And this would be your Pismo upgrade card, Daystar/XLR8 MACh Speed G4 550? interesting, wasnt cheap I guess.

well, thats the first solution I would try. What iBook G3 is it, Clamshell or white? Both have USB1.1, so a USB wifi stick should work under Tiger. Edimax ew-7811un USB Wi-Fi adapter, the first generation model of it will do WPA2.

I wonder how secure a MAC address filter network actually is..I mean its a bit annoying setting that up as you would have to put in all your devices, phone, tablets, desktops, portables..but should be better than WEP.
