My mistake, Tingo! the code is using a One-Shot-Pulse generated at pin 2 and not at pin 3. I've just realized it when changing the MEGA and have the same issue than you. Pin 3 was in used when there were some play algorithms still using a simple bit toggling. When all algorithms started to use OSP, ...
The lettering is not fading but I have doubt about color : unlike TO8 keys the color keys on MZ-700 appear to be sensitive where there is a yellowish taint. The part where there is no yellowish taint has no changes. The lettering looks better indeed.
I tried to retrobright some MZ-700 keys without UV using only H2O2 and heat through a sous-vide cooker (not sure how to call that machine).But I got a better result with TO8 keys as I could refine the experiment.
So the situation is you have no screen activity and no sound activity. Sounds like the CPU is not running. The more I think, the more I believe we need an arduino to take the Z80 bus ownership and be able to access RAM, ROM, VRAM and Intel chips to make some tests and diagnostics. - Monitor ROM ($00...
Many people helped me, to collect information about the machines and i wired them into the emu. The new is MZ80K color from SUC-UK !! ... But if you like, you can help me to modify one 80A core into singlelinemode and reconfigurable CTC. Hi Sharpals, it is not very clear whether you are connected t...
