Hi all!,
i'm new in the forum and also a newbie D64 owner
No experience at all with this machine, so a previous user manual, some books an schematics inspected
Afther a considerable troubleshoting, i've an Eurohard D64 working ... or almost.
Actions performed:
- A depth cleaning
- A new 6809 inserted
- Some replaced keys
- Two new eproms (IC17 and IC18)
All looks well, but some colours are wrongs : green is not pure, almost yellow, red doesn't exits , instead a gray tone is displayed.
Therefore, the image is very clean, with no interferences.
Sounds works and graphics modes seems too.
Did you ever hear something similar? i'm affraid that a hard investigation on 6847 and PAL subsystem should be perfomed
Any information, manual to read more 'easy' to understand than IC's datasheets?
Thanks in advance.
