Composite video mod?
Posted: Sat Jun 01, 2019 6:10 pm
Hello all!
I'm new here. Recently I repaired an Oric Atmos that basically sat in a box for many years. Bought it once as "working", which turned out to be not the case, and since I didn't have spare parts like CPU, VIA, ULA etc it got boxed up. Years later I acquired some parts but was busy with other things. So parts got stored, and well... as usual 'life got in the way'. Never used an Oric machine back in the day, so I have no experience using or programming it. Not familiar with 6502 assembly either.
Anyway, I'm no stranger to hardware (quite the contrary!). So recently decided to have a go at repairing this nice machine. I succeeded in doing so, and did some modifications in the process. Most significantly:
Which brings me to my question: is adding a composite video output to the Oric considered a "solved problem" ? Or are people still struggling with that / only unsatisfactory solutions are known?

- All important IC's socketed now.
- Faulty RAM replaced not with the original 64K x 1, but with 2 pieces 64K x 4 bit DRAMs.
- Composite video output.
