Is this fixed lol. I bodged a wire from NTSC to the composite jack. Is this the test pattern you get when the keyboard isn't connected? I did this right before I had to go to work so no time to test further.

Yes! I think this is it. There is activity on the pin marked NTSC on the schematic. Looks to be about 1 volt, which Google says is right. So I'm gonna go ahead and buy that adapter. Thanks again for the help, I'll keep you posted on how it goes.

That's probably a good solution if there is any signal being generated. I'll put the oscilloscope on it first, if I see a signal, I'll part with the cash. Thanks again. Maybe this will work and I can get back to that horrid SE 30 you were helping me with lol.

Ok so I pulled the mobo, reflowed that connector for the composite (it was not as janky looking as 8 but guy's, it was a proper connector) and reseated everything in sockets with some deoxit. No change unfortunately. Maybe I'll reflow everything after work and see what that does. If not I'll be...

Just got this IIc, bought as non working. It does have power, it beeps and the disk drive seeks. The issue is no display. I tried on the monitor that came with it, my television, my known working IIe monitor and RGB monitors for both a IIGS and LCII. The last 2 make the computer do nothing at...

Interesting, when I have time (tomorrow maybe) I'll scope out all the RAM SIMMs. If I can identify one or more that aren't properly connected, I can fix it or replace if it's more than one or 2. It'll probably be replaced though. This Mac was obviously stored on its side as all the corrosive goo...

Video ROM. I fixed it. No change. I'm thinking that cause Mac board seriously now

Update! No activity on A(0). It blips on the scope for about 3 seconds then nothing. There seems to be activity on all the other pins on ram and ROM. Confirmed on the video ROM and UD8.

Ok so I salvaged the original ROM. It was manky AF, but it was all surface crap on there. No change at all. Again with the thermal cam, the ICs on the front are getting warm like they're doing something. It's the video ICs that do nothing at all. If I assume one of these ROM sticks works, what's...

Ok some of you might have seen this on reddit already. I bought a nice on the outside se 30 a few weeks ago. So far I've recapped the main board, changed the ROM (ROMinator) and RAM (modern RAM 16MB), then I used the charts on the schematics to check the address and data lines. Found a bunch of...
