apple2 europlus (1982)

[counilh]

Hi,
I'm trying to revive an apple II europlus that I bought in 1982 (the equivalent of 2 months salary !) and with which I learned programming and computers. I have some problems re-reading the old floppy disks (a master dos 3.3 ok - also locksmith4.0 - but no game and no floppy under cp / m is readable).
I would like to use your protocol to dialogue with him and show my sons that there is something other than Fortnite in life ... However, in the 2020 photo I do not understand all the wiring (https://user-images.githubusercontent.com/5579123/79223990-577fb400-7e28-11ea-9ac6-105dfd441894.jpg) compared to previous photos (2016 )

If I understand correctly there are 4 pins (3,6,7,8) on the arduino which go respectively to the ports (14,5,2,15) of the game port of apple2. Why on the photo of april 2020 there are 2 rows of the plate ribbon that go to the apple game port. Moreover you use (GND and 5V arduino). Are they okay on 1 and 8 of the game port? Can you enlighten me.
For the rest I am under unbuntu 16.04 lts and I am having fun with raspi and arduino. I managed to install and compile the examples with PLASMA. Also I expect a lot from your help.
Thanks in advance
Regards

Hi there- You can see the pins used for the game port on my website: http://schmenk.is-a-geek.com/wordpress/?p=239 Follow the links to for the game port diagram to make sure you connect the correct pins. I’m not sure where you found the picture from 2020, but it looks like they used a breadboard to build a temporary setup. It may have made it easier to debug, as well. You will need to get floppy images onto real floppy disks in order to run the PLASMA programs on the Apple II: https://github.com/dschmenk/PLASMA/tree/master/images/apple <https://github.com/dschmenk/PLASMA/tree/master/images/apple> Good luck

Hello Dave,
Thank you for the quick reply. What put me in doubt is a correspondence between you and "erangell" (#16) where this montage photo (2020) was a little different from yours ...I will respect the recommendations of your website but for the moment I am trying to replace the keyboard (https://knzl.at/ps2-keyboard-for-apple-ii/), the GI 331- 0931-B having let go, I can not find on the internet the datasheet of this component to read what he has in the stomach ...

Hi Denis- You will need something a little ore sophisticated to replace the keyboard encoder ROM than what you linked to - it expects a working keyboard encoder. Since the GI 331 on the keyboard is unobtanium new, you’d have to source a working pull or a complete replacement for the encoder board like: https://www.reactivemicro.com/product/superencoder-for-apple-ii-and-ii-plus/ <https://www.reactivemicro.com/product/superencoder-for-apple-ii-and-ii-plus/> I’m not sure the above link works with the Europlus - you would have to ask Reactive Micro.
