Thanks I luckily found a board for parts or repair I can maybe use to fix my main board.

Make sure this pin has a good connection. I noticed this was faulty on mine causing issues.

I have a Mac II that WAS fully working I had just cleaned and right before I put back on the lid I added a drive B cable to go out the back (for FloppyEmu). Banging my head on the wall but I shorted something while messing with the cable while power was on and now drive A or B will work. They...

------------------ You must have the keyboard connected for the computer to work (don't turn it on without keyboard plugged in). Just unscrew the keyboard and take it out of the frame. When you pull out the chip (and don't have good tools for it) just use a flat-head and very SLOWLLY rotate...

Take a look at this cable (idk if it tells you anything): https://retrofloppy.com/products/ "Apple /// Color Composite Video Adapter" Going to test out that cable and see if better color comes through. You can still get "color" via the B/W composite port on Apple /// but I think this might be...

Did you see any of these? https://apple3.org/Documents/Technotes/TA30822.html https://apple3.org/Documents/Technotes/TA40749.html https://apple3.org/Documents/Technotes/TA48103.html Also might ask on AtariAge forums as well. I wonder if anyone has figured out how to make Apple II to Apple...

Finished my Internal to External converter complete with two-way switch just like IIc had. I can now boot from external port with FloppyEmu or flip a switch and boot from internal. Here is the switch that changes from internal to external drives. Or I can disconnect converter box and...

Interesting but the solution I've adapted from FloppyEmu IIc converter is much simpler and works at the hardware level.

Made it so I can boot from external floppy port. Getting parts to finish it with a switch etc but it works great. Same concept as the FloppyEmu IIc adapter that swaps the drive-enable lines.

So found out the adapter works fine in Apple IIe but not Apple II+

Because Apple II controllers are super expensive and Atari controllers are made new to this day for super cheap.

So I just got one of these: https://console5.com/store/byteboosters-sega-atari-snes-joystick-adapter-to-apple-ii-e-c-c-iigs.html I've tested with two different Atari Joysticks with Mario Bros on Apple II+ and the jump button is always pressed (DPad / Joystick works fine). Using an old Apple II...

You also keep track of how many people had these go bad while using original PSU? The Apple ][+ I got had a bad PSU making a clicking sound with voltages not good. Now that I replaced it with a custom PICO based one my guess is there will be less issues down the line. I have original PSUs for...

Besides the bad ram the bad logic chip was: SN74LS153 to the right of the last upper row of ram as you can see in the picture.

You're right I had 3 bad ram chips. Guess I tested wrong last time. Now its 100% stable and working! Ran it for an hour with no issues. I also added some heat-sinks on chips that got hot. Hopefully it keeps them from overheating and lasting longer. Also modified my FloppyEmu cable so I can...

So I'm having a problem still after adding a disk-drive interface card. It stops reading drive and spits garbage data similar to @bibilit issue he shared here. FYI: Frogger I loaded above was done via tape input.  Many times loading from tapes will have the same/similar issue. What I do: *...

So I made a cable based on this: https://www.bigmessowires.com/2017/01/25/floppy-emu-on-the-apple-iii/#comment-236297 Would be nice if someone would test this on Apple III+. It works on internal and external drives BUT sadly you can't boot from external drive on Apple III so I want to see if...

So was reading people got the official Floppy Emu working on Apple III with a converter cable. However I see Chinese Floppy Emu devices that expanded on Floppy Emu and work in Apple II computers. My question is doesn't anyone know if the card interface is the same on Apple III and Apple II for...

Also any suggestion for a JoyStick interface card? Got frogger running from .wav / tape.  Everything working good so far.
