Apple II Plus Clone: ABC

white_slots_s

This Apple II Plus clone i got in 2018 :  https://finapple.hho.fi/finapple/index.php/2018/11/20/once-there-were-apple-ii-clones but actually never started working, cleaning and testing on it untill now.

board_wired

“Made in Japan” Is printed on the motherboard but this style board can be seen used in lots of different “branded” clones and cases. I had the original NTSC/60Hz 14.31818 crystal i.e. not been modified to european 50Hz usage.

I was also modified with 3 wires to slot 7. I hoewever removed those, but documented it carefully if for some reason that needs to be recovered.

 booted_with_wires_attached

With the wires still attached i could not get correct colors out of it. The display i used does NTSC so it wasn’t the display issue.

wires_removed

After the wires removed i got the correct colors.

karateka_gfx_oddity_2_s

With the wiring removed i could see odd patterns (boxes) instead of “lines” as it should be. What is going on here?

color_test_4

The colors look ok with Samsung LCD/TV with composite/scart adapter. Slight waving color inference on screen specially on BLUE color  as well with white balance etc. Looks like inteference of somesort.

no_color_with_pbvm

No colors with my JVC 9″ PVM monitor either. 

 skyfox_white_very_lowq

The white is dispayed oddly.

broken_plastic_s

The keyboard was cleaned and the spacebar fixed. One out of two small plastic holders for the spacebar metal bar wes brolen and replaced from another clone keyboard. Luckily i had kept that. The keyboard is quite good guality and easy to write. Much better than some of the clone keyboards used with Europlus’s.

keyboard_repairing_s

Borrowing parts from an another clone keyboard.

 

chip_in_wrong_socket_s

Swapped some chips… but it’s always good to use correct chips 🙂

apple_ii_plus_clone_abc_s

Added a own label to the lid “Chipper”. It was computer shop back in 80’s in Finland. I though it would be proper and period perfect. Even in reality most likely some cheaper general electronics store would have sold such clone over here like Bebek.
