Need help pointing to strange video problem on SE/30

[genie_mac]

Nice one!

 

[uniserver]

thanks man you were a great help!

 

[insaneboy]

Woohoo!!! Nice work.

 

[uniserver]

Hey what can I say this forum rules...

Mega smart, Determined, Generous people!

fixing that really made me happy.

 

[genie_mac]

Glad I could help. Hope it wasn't just beginner's luck

You guys are an inspiration! Now i'll have to go take a closer look at my board with gangster pinstripes.

 

[uniserver]

came across another SE/30 gangster pinstripe issue,

this one needed 3 lines ran.





Used the VOM, followed the schematic, it's good to go.

Vid 0, Vid 3, Vid 6

 

[genie_mac]

This is getting too easy

 

[uniserver]

well I still have one that is dead, It acts like there is no rom simm inserted,

do you have a magic trace fix for that one ?? lol

the cap near the battery leaked real bad causing corrosion on many of the via's surrounding it.

You know that this is the type of situation that makes me start to think that replacement is better than restoration, right? Not uniserver, he's Marty McFly. Can't back down from a challenge

 

[uniserver]

Here is another Gangster pinstripe SE/30 video fix.

This one also needed a new ADB Fuse. The ports on this board are BEAT, this thing was well USED...

ITs all good now ... works great now. Protected with Anti Corrosion/Polish Treatment.

Awesome! So how many of these video issues have you fixed Uniserver!?!

I pulled this post back up because I am about to embark on trying to fix a scsi issue on another se/30

 

[uniserver]

just 3 so far.

its really a great feeling when they work right again.

i have that video rom for you. its right here. just come over after 6pm so i will be here man.

for SCSI issues I would suggest watching techknights video on youtube.

i just realized bob ross died at age 52, man what the heck, these great people… so young..

for SCSI issues I would suggest watching techknights video on youtube.

And we have people like you that take the time and fix these machines to keep them running, to fill my shoes persey, as I dont have time to do it much anymore. But I digress. I did manage to fix that machine, But I got a board from JDW that acts as if no ROM simm is inserted either. it passed all continuity checks. I think the GLU is bad, as its not switching memory map allocations to access ROM at ADR 0.

 

[uniserver]

So far I have (2) SE/30 boards that do exactly that. they act as if the rom simm is not installed.

Once I can save up enough I'm def. bringing my Classic II to Uniserver to get recapped, and if I can talk him into it, look at my video wobble issue, to see if the analog needs to be recapped, or it is some kind of magnetic interference issue.

Those of us within a reasonable distance are lucky to have him nearby.

 

[uniserver]

sure , no problem.

 

[uniserver]

No Problem.

I love this thread. So am I right in assuming the wired traces bein run between IC's are basically just replacing existing printed circuit traces that have corroded out of continuity due to leaky caps etc??
