I wonder if this is a Umax, they made some apple clones for a while.
*Does some googling* nope this is a motorolla one, just missing the label. Umax made some similar cases but this ones almost certainly Motorolla.
Did you also do the two really big high voltage caps? I followed a guide that listed those as "should not need replaced" but mine was acting strange, running for a while ~5 mins or so then clicking on and off rapidly. Replacing those two big ones fixed that problem and its worked perfectly since.
I'm sure a lot of people have done this, but wanted to report my results anyway. The drive was not too bad of shape dirt wise, it was a little dusty but not near as bad as some I've seen. It was not only unable to read/write disks but it also could not auto eject and even manual eject was...
Success!!! I have gotten the system working now, I had to buy an old Dell LCD that was known to work with vintage machines. Using a Dell 1707FP 17 inch LCD, works great! I found that the correct settings were 1 and 2 on the adapter I have.
On the power supply I replaced the two large 250v...
Ok I've not replaced the two big can 220uf 250v caps. The guide i had said "shouldn't need replacing" but at this point its the only caps not redone. I've ordered a few and once they get here I'll replace those and see if that fixes the problem.
And I spoke too soon on the stutter, I just fired it back up and it instantly came back. It stopped after a few seconds and ran smooth which is new, then came back and won't go away now. Damn...
Ok, I removed the daughtercard and resoldered one of the smds that was a little suspect in its soldering. have better soldering tips now too, so I think I did a far better job putting both the SMD and the daughtercard itself back on. Much neater joints! I let it run a while and no stutter...
I did but it was my first time doing SMD's. I had one fall off first time, and put it back on. Maybe I should recheck that work. I hate having to unsolder that thing a third time but it sounds worth looking into.
I'm brand new here, but not new to Macs at all having grown up in the age of the Apple II and the very early macs. I was hankering for my old 68k mac days and I picked up a Mac IIsi to restrore.
My first task was to recap the power supply. my first time doing such a thing though I do have a...
