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!

+1 spent the money on that as my first iron. Love it

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! https://jcm-1.com/product/jcm-universal-keyboard-encoder/

Guess who has another apple iii board coming in the mail... Don't worry, this project is still taking up my downstairs More to come!

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...

Ordered an extra apple iii? Got one off ebay/found another one locally?

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

Got any recommendations for a joystick? I need one but haven't looked too far into it

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. https://www.apple3.org/Documents/Schematics/Timing Logic.jpg 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...
