Ok so this is interesting. I made the order with UTSource on the 25th of October. I received a shipment notification on Oct 28th with a 9 digit code that is untrackable (with all the Asian postage trackign sites I have used regularly anyway). I Thought this was weird as I paid for and chose...

my LC, Lc II, and LC III system (i have 8) all can start fine WITHOUT a pram battery. the psus are problematic on these systems though.

That number doesnt work with 17 track either.

So in other words it cannot be tracked until its past US customs a couple days from actually being delivered?

The only update I have is UTsource sent me an email a couple hours ago saying my item was shipped USPS but the tracking number they sent was only 9 digits! I emailed them back saying thats not a valid tracking number. So hopefully they respond.

oh what a crapshoot! Well fingers crossed.

I just selected the quantity I wanted and went through the checkout process.. As I would do on any other website. If I did something wrong in the process I would say the interface is very counter intuitive. Yes I will let everyone know how it turns out. So far all I received was a notification...

I paid via paypal so if there is an issue I am confident in thier dispute process. And I own maybe 8 Macintosh LC's. But I know, there is always a risk. I am no stranger to buying chips that dont fix the issue.

The bottom two thirds? Why does it have two 85C30 Serial Chips in one? What is the benefit of that? Trag I bit the bullet and purchased 4 of the AM85C80-8JC. Lets see how that goes and what the time to delivery may be. Says almost 2300 in stock so who knows.

So like Amazon to a degree... Good to know. thank you.

Ok I guess it certainly worth a try as they are the only people to stock the exact part. Thanks Josh.

Thanks Josh. I have been a little off put by UTsouce needing an account before being able to request or purchase anything. Have you or anyone else ever actually purchased from them before? I have purchased plenty from Jameco, Grainger, Mouser, and digikey... But not Utsource. I just want to make...

One of my only 512KB VRAM modules I own thats in my LC II went bad this year or last: I bought 4 of the exact same type of TC524258BJ-10 Ram Chips online. I ended up using 3 of the 4 chips I purchased. I have a feeling one of them may not have been bad but a bad contact. I marked them and...

YMK I appreciate all your help I honestly do. But seems noone else is chiming in at all and this machine has turned into a money pit. Im just going to shove it in the closet and go back to repairing some MAcintosh II boards as those are more straightforward than these classics. I cant say I am a...

so are they selling a new/modern reproduction board for the classic? I heard rumors

I suppose. but I dont know what to try next. And now the RAM isnt working properly.

So I installed the New zilog Scsi chip. Same exact problem. But now my machine is only reporitng 512KB with no expansion RAM card installed. And 2048KB with the expansion ram card! What gives? I am starting to think the problem was something other than the scsi chip all along and now its...

I am looking to buy the Zilog equivalent as I dont see another option at this point.

Ok I ordered a Zilog variant. Fingers crossed.

so the traces are good then. whats left? just the 53c80?
