It's been February since I posted?
Well life got crazy. Project got put on hold, lots of projects at work, promos, new job roles, etc.
On top of weekly concerts, backpacking and everything in between I haven't gotten to work on this!
I did find out the last information though!
Resistors...
Unfortunately not the most software available as you said..
https://www.apple3.org/iiisoftware.html
This is the place I know with all the best disk images. Even then there is not the most..
Interested to see what others say!
Guess who has a new apple iii board!
Guess who also still has the same damn issue of no video!
lol, at least I have a bunch more ROMs now!
Man these things hate me.
The timing logic on this one is also broken
The problem with this one is straight timing logic to start...
Man is everyone's apple iii literal garbage?
I swear every story is "I got it from a dumpster" or "I had grass growing in it" "I had a rat colony"
So interesting to see where these machines ended up!
Jcm makes a replacement!

Good stuff on getting it to work!
I hope I'll get there someday.. :)
Maybe I'll win/find a donor board and really get going!
What 5v ram chips did you use? Model no?
I need to probably replace all of mine..
Well, replaced got a few IC in the mail and replaced those. B12 because I thought I had a weird issue with dividing signals. But it's still there after replacement.
Instead of 1mhz I get .9, weird.
But I did replace G12, which is the next part in the timing logic,
No matter where I moved the...
Welcome to the club! Started with no knowledge of schematics/how an oscilloscope works.
Making my way slowly through it. It's a beast for sure, not as much out there as the ii
bought for 100 shipped for 100.
I don't like to say the shipping cost!
I took a huge gamble and came out ahead.
Still technically $100! ;) we don't talk about shipping
But yes. USD, shipped from cali -> nc
I fully expected it to show up in pieces. The huge sigh of relief I had when I unpacked everything and to my surprise no damage!
It's a bit yellowed. But for $100 I really can't complain that much.
Well, back at it again. All chips back in their sockets.
A different problem now.
The CPU is clocking at 1mhz instead of 2. I'm trying to make sense of this and maybe I'm looking over something simple.

So here's where the signal for...
I looked at my board and thought "how leaky could it really be"? It didn't look that bad, but I couldn't see that well between the giant group of caps at the bottom.
Then took off all the caps at the bottom of the board to replace and I couldn't actually see anything on the board besides gunk...
Well that's a plus on the keyboard light at least!
I bought this guy for my project: https://m.aliexpress.us/item/3256801783387968.html?spm=a2g0n.order_detail.order_detail_item.3.3501f19ctjVh2i&gatewayAdapt=glo2usa&_randl_shipto=US
Sorry if it's a mobile link but it's the ZEEWEII DSO1511G...
Are you able to swap around some of the RAM chips to see if it makes any difference?
Specifically the ones in the top left of the RAM board are zero page ram. Take some from the left and move it to the right of the board and vise versa.
Any difference there?
The video I'm pretty sure like the...
Well, now that the holidays are out of the way.. my board has been sitting lonley for a bit as I've been out of town. Traveling, family, etc.
I had the day off so I decided to give the /// a vinegar bath, yet another scrub, and a alcohol bath to displace anything.
Scrubbed in a bath with...
Argh!
The se/30 sails the seas with a rominator ii and new caps! Sound is still fucky on boot... but works perfectly in the OS. No clue but not too worried..
Installing 7.5.5 now as my classic ii covers the 7.1 front
Does anyone have a suggested amount that they found to be "the best" for...
