Not sure if this has been covered before, but I want to get peoples feedback on the ever increasing issues with getting your old machines to display on modern displays.
If there is a SCART lead for a particular machine, this is great as it means it is easy to get your display up and running with crystal clear visuals. However some of the more unfashionable or rare machines don't have this option yet and you are forced to use the old RF cable. Increasingly I am finding it hard to get a good display using this.
I picked up a mint condition Oric Atmos and the display is fine apart from some horrendous static audio blasting out and some untuned parts of the screen. My question is, is this simply a case of not being able to tune the TV in enough or is it possible to repair or improve the circuitry in the computer?
The problem with newer TVs with RF connectors is that the tuning is digital and you cant fine tune it very well. You are stuck with the increments the manufacturer has set. This is fine for some machines, but others dont like it all!
I'm only theoretically speaking as I have not witnessed an issue like that myself....
However, are you using a dedicated TV for the Atmos, or are you using one in which you would normally watch the TV channel you are using for the computer?
I'm thinking that if you leave the Atmos on, and do a programmed channel scan on the TV, it might auto fine tune to the specific frequency coming from the Atmos RF modulator when it gets to that channel. The drawback would be that you would probably lose the programming for the rest of the channels you were originally using. Either way, it might be worth a try to see if the problem resolves itself. You can always re-scan the television channels again if you need to.
I've indeed had the same problem with my Nintendo Entertainment System and Pioneer Plasma. The NES does not provide, apparently, a clean enough signal to tune-in perfectly so it makes the fixed digital tuner in the TV even more of a pain to deal with. Keep in mind that many LCD/Plasma TVs do, in fact, have fine-tuning capabilities for their RF inputs (sometimes you have to really search the menu system for it). I ended up using the composite cable since the NES has one instead.
