Finally, a working portable!

Finally i have my portable working!

Just got it's logicboard back from it's 8,000 mile round trip to techknight (who i must thank for all the work he put in, removing all 32 ram chips not once, but twice!)

I put it all back together (amazingly i didn't loose any parts while it was sitting around disassembled), connected up a battery and hit a key on the keyboard and finally got a *bong* not followed by the chimes of death . However i still had messed up video, a bit of fiddling around revealed there was a break in the display cable, once i got the cable in to correct position it booted up absolutely perfectly which revealed that it had been decommissioned in 1998! I was very glad to see the 1mb ram card it came with works fine, i had a horrible feeling it was going to have a dead ram chip on it like the portables motherboard did

It still has a couple of lines across the screen which i'm not sure if they are dead rows of pixls or a artifact of the break in the display cable, but i can live with them

Next step is to get my SCSI2SD installed in this and give it a clean install of OS 6, just need to find a 34pin ribbon cable....

Congrats on the Portable! TechKnight is one of the masters of this dying art of Dead Mac Necromancy.

I think its the cable that's giving you problems, or a loose connector on the board.

Congrats, the Portable is among the ones i have missing, i will like to have soon.

Thanks guys

Yeah the portable was one of the ones i never thought i would be able to get hold of, so i jumped at the chance to buy one. (even though it did need a hole lot of work (and money) to get going...)

I like the portables.  I never even saw one in the flesh until I got one.  Weird as that is the same story about the Apple /// I have.  

 

[max1zzz]

Neither had I, but then that's not too amazing since the portable was introduced 8 years before i was born

Dying art? HA... this is just getting going!

yea, that was NOT fun.... Something I really dont wish to do again :-/

Well, when I get fed up with my portable, you might have your chance at it again, techknight!

Glad you got it going! It must be nice to have a fully working portable, I'm still trying to get my backlit completely working again. Getting closer with every repair!

Nice work!

hmm... can't seem to get my portable to recognize my SCSI2SD,.

i'll have to go grab a hdd and try again....

EDIT: The 40MB drive out of my LC is seen just fine and the portable is more than happy to boot from it. can't see why it refuses to see the scsi2sd

haha, of corse installing the jumper for termination would have helped

Seems my LCIII / 475 (can't remember which i initially tested the SCSI2SD on)  isn't too fusssy about termination

I think there's this guy on here that builds these awesome adapters with active termination who could've answered your question.

Oh wait, he did!

 

[max1zzz]

hehe I really should have known better there... For some reason i assumed that pin was for termination power to the bus.... i don't know why... my adapters aren't like that and i had had a really good look over the board before i assembled it

Oh well, it's absolutely screaming now even on my old slow SD card it boots 6.0.8 (from happy mac to desktop) in about 5 seconds
